Abstract
The PD-1/PD-L1 checkpoint pathway is important for regulating immune responses and can be targeted by immunomodulatory drugs to treat a variety of immune disorders. However, the precise protein-protein interactions required for the initiation of PD-1/PD-L1 signaling are currently unknown. Previously, we designed a series of first-generation PD-1 targeting peptides based on the native interface region of programmed death ligand 1 (PD-L1) that effectively reduced PD-1/PD-L1 binding. In this work, we further characterized the previously identified lead peptide, MN1.1, to identify key PD-1 binding residues and design an optimized peptide, MN1.4. We show MN1.4 is significantly more stable than MN1.1 in serum and retains the ability to block PD-1/PD-L1 complex formation. We further characterized the immunomodulatory effects of MN1.4 treatment by measuring markers of T cell activation in a co-culture model with ovarian cancer cells and peripheral blood mononuclear cells. We found MN1.4 treatment reduced cytokine secretion and suppressed T cell responses in a similar manner as recombinant PD-L1. Therefore, the PD-L1 interface region used to design MN1.4 appeared sufficient to initiate PD-1 signaling and likely represents the minimum necessary region of PD-L1 required for PD-1 recognition. We propose a peptide agonist for PD-1, such as MN1.4, could have several applications for treating autoimmune disorders caused by PD-1 deficiencies such as type 1 diabetes, inflammatory arthritis, or autoimmune side effects arising from monoclonal antibody-based cancer immunotherapies.

Abstract
With over 39,000 students, and research expenditures in excess of $200 million, George Mason University (GMU) is the largest R1 (Carnegie Classification of very high research activity) university in Virginia. Mason scientists have been involved in the discovery and development of novel diagnostics and therapeutics in areas as diverse as infectious diseases and cancer. Below are highlights of the efforts being led by Mason researchers in the drug discovery arena. To enable targeted cellular delivery, and non-biomedical applications, Veneziano and colleagues have developed a synthesis strategy that enables the design of self-assembling DNA nanoparticles (DNA origami) with prescribed shape and size in the 10 to 100 nm range. The nanoparticles can be loaded with molecules of interest such as drugs, proteins and peptides, and are a promising new addition to the drug delivery platforms currently in use. The investigators also recently used the DNA origami nanoparticles to fine tune the spatial presentation of immunogens to study the impact on B cell activation. These studies are an important step towards the rational design of vaccines for a variety of infectious agents. To elucidate the parameters for optimizing the delivery efficiency of lipid nanoparticles (LNPs), Buschmann, Paige and colleagues have devised methods for predicting and experimentally validating the pKa of LNPs based on the structure of the ionizable lipids used to formulate the LNPs. These studies may pave the way for the development of new LNP delivery vehicles that have reduced systemic distribution and improved endosomal release of their cargo post administration. To better understand protein-protein interactions and identify potential drug targets that disrupt such interactions, Luchini and colleagues have developed a methodology that identifies contact points between proteins using small molecule dyes. The dye molecules noncovalently bind to the accessible surfaces of a protein complex with very high affinity, but are excluded from contact regions. When the complex is denatured and digested with trypsin, the exposed regions covered by the dye do not get cleaved by the enzyme, whereas the contact points are digested. The resulting fragments can then be identified using mass spectrometry. The data generated can serve as the basis for designing small molecules and peptides that can disrupt the formation of protein complexes involved in disease processes. For example, using peptides based on the interleukin 1 receptor accessory protein (IL-1RAcP), Luchini, Liotta, Paige and colleagues disrupted the formation of IL-1/IL-R/IL-1RAcP complex and demonstrated that the inhibition of complex formation reduced the inflammatory response to IL-1B. Working on the discovery of novel antimicrobial agents, Bishop, van Hoek and colleagues have discovered a number of antimicrobial peptides from reptiles and other species. DRGN-1, is a synthetic peptide based on a histone H1-derived peptide that they had identified from Komodo Dragon plasma. DRGN-1 was shown to disrupt bacterial biofilms and promote wound healing in an animal model. The peptide, along with others, is being developed and tested in preclinical studies. Other research by van Hoek and colleagues focuses on in silico antimicrobial peptide discovery, screening of small molecules for antibacterial properties, as well as assessment of diffusible signal factors (DFS) as future therapeutics. The above examples provide insight into the cutting-edge studies undertaken by GMU scientists to develop novel methodologies and platform technologies important to drug discovery.

Abstract
Endocrine therapy (ET) in combination with CDK4/6 inhibition is routinely used as first-line treatment for HR+/HER2- metastatic breast cancer (MBC) patients. However, 30-40% of patients quickly develop disease progression. In this open-label multicenter clinical trial, we utilized a hypothesis-driven protein/phosphoprotein-based approach to identify predictive markers of response to ET plus CDK4/6 inhibition in pre-treatment tissue biopsies. Pathway-centered signaling profiles were generated from microdissected tumor epithelia and surrounding stroma/immune cells using the reverse phase protein microarray. Phosphorylation levels of the CDK4/6 downstream substrates Rb (S780) and FoxM1 (T600) were higher in patients with progressive disease (PD) compared to responders (p = 0.02). Systemic PI3K/AKT/mTOR activation in tumor epithelia and stroma/immune cells was detected in patients with PD. This activation was not explained by underpinning genomic alterations alone. As the number of FDA-approved targeted compounds increases, functional protein-based signaling analyses may become a critical component of response prediction and treatment selection for MBC patients.

Abstract
Abstract
Microcalcifications are an important mammographic feature of ductal carcinoma in situ (DCIS) and are detected in 85-90% of abnormal mammograms. Calcium transport and calcium channels regulate microcalcifications and are essential for breast cancer proliferation. The breast duct intraductal lumen, which is the origin of ductal carcinomas, has been shown to be a non-sterile environment. We hypothesize that the intraductal microbiome influences calcium handling and mineral deposition in breast cancer. Bacteria have been known to enhance the formation of mineral deposits, including calcium salts, in various non mammalian microenvironments via secreted factors or extracellular vesicle mediated nucleation. We performed a clinical study on a cohort of 150 women who received a suspicious mammogram and were subjected to a follow up biopsy, and we identified differences in calcium handling microbiota between patients who harbored a malignant disease with respect to benign controls. To mechanistically study the role of microbiota in breast cancer calcium handling, we developed a 3D spheroid model of ductal carcinoma in situ using the BT-474 cell line. When exposed to high concentrations of calcium in the culture medium (from 1.75 mM to 2.05 mM), spheroids developed calcium mineral deposits in a calcium dose dependent manner; deposits were identified in internal regions of the spheroid, which correspond to hypoxic areas of DCIS in vivo. Extracellular calcium deposition correlated with cell survival in face of a toxic calcium level. Spheroids were cultured under a continuous flow of Lactobacillus rhamnosus LMS2-1-derived EVs over the course of two weeks. EVs were isolated by sequential ultracentrifugation; the 100K fraction was retained and characterized in terms of size, concentration, and protein content. EV treatment induced increased calcium export and mineral deposition in a dose dependent manner. Our findings support the hypothesis that L. rhamnosus-derived extracellular vesicles influence calcium regulation and mineral deposition in the hypoxic breast cancer milieu. More studies will be undertaken in the future to unveil molecular mechanisms that underlie this interaction, both at the cancer cell and the microbiota level.

Abstract
Abstract
Immunotherapy has shown tremendous promise in the treatment of blood cancers; however, treatment typically fails when attempted with solid tumors, such as breast cancer. However, the cases where immunotherapies have been successful in breast cancer, the results have been remarkable: full remission of stage 4 disease has been observed. This highlights the need to elucidate how the tumor microenvironment (TME) fosters a context of molecular crosstalk that is hostile to inflammatory, anti-tumor immunological responses that present a significant roadblock to consistently successful immunotherapy. Aberrant IL-33 present in the TME is believed to be one of these major factors that drives tumor progression via its ligand, ST2, and the subsequent recruitment of IL1RAcP. This activates MyD88 cascades in dysfunctional myeloid immune cells and myeloid derived suppressor cells (MDSCs), eliciting immunosuppression that promotes tumor tolerance and subsequent disease progression. To this end, preventing IL-33/ST2 signaling activation is an attractive target to possibly manipulate immune cells to recognize and mount a response against tumor cells. Our previous work has identified 4 IL1RAcP hotspot residues of interaction between it and the ST2/IL-33 complex: R157, K238, K343, and K346. Here, we designed peptides, which mimic these hotspots and the adjacent residues that interact with the ST2/IL-33 complex. Wild type peptides inhibit trimer formation in vitro as determined by immunoprecipitation and chemical crosslinking experiments. Modifications introduced to increase rigidity and stability increased affinity in vitro and showed inhibition of downstream signaling in reporter gene cell models.

Abstract
Lung Cancer carcinogenesis is the outcome of a field of premalignant changes that occur in the bronchial tree leading to the overt emergence of the malignant lung cancer. We sought to study the proteome of the microbiome associated with the premalignant bronchial mucosa epithelia. The overall goal is the identify functional relationships between the bronchial mucosa microbiome and the risk of developing lung cancer. We evaluated the proteome of the microbiome using mass spectrometry and specialized microbiome authentication software. This method was applied to a case-control study of plasma samples donors of physician health study who donated plasma at different times prior to the onset of Non-Small Cell Lung Cancer. We also examined bronchial mucosa tissue samples near to, and distant from, the tumor harvested from surgical lobectomy specimens. Highly significant protein biomarker differences were found in the plasma and in the tissue samples that were blindly associated with cancer. These included specific proteins from the mucosal microbiome that may have functional role in the carcinogenic process. These key diagnostic risk markers were shared between the premalignant bronchial mucosa tissue and the plasma, supporting the concept that risk markers of bronchial mucosa lung cancer carcinogenesis can be detected in the peripheral circulation.

Abstract
Abstract
The goal is to reverse cancer immune evasion at the level of the sentinel lymph node (SLN). Reduced expansion of CD8+ T cells and other innate immune effector cells in the cancer draining SLN is associated with progression and resistance to checkpoint inhibitors. Cancer-derived extracellular vesicles (EVs) that are PD-L1+ suppress immune recognition at the level of the SLN. The experimental goal is to remodel the SLN to overcome cancer EV-associated immune suppression and induce immune rejection of the tumor. We developed three methodologies for this project: a) Collection of draining lymph fluid to characterize EVs shed by 4T1 syngeneic breast tumors growing in the mammary fat pad. b) Chromatographic separation and characterization of the repertoire of EVs shed by tumors into the tumor microenvironment interstitial space using western blotting, mass spectrometry, and electron microscopy. c) Nanoparticle (NP) delivery of purified populations of EVs to the tumor draining SLN in combination with cytokine chemoattractants for innate immune cells recruitment. We characterized the in vivo interstitial fluid (IF) content of a GFP-4T1 syngeneic murine cancer model to study resident IF EVs transit to the draining lymph node. GFP labeling confirmed the IF EV tumor cell origin. Molecular analysis revealed an abundance of IF EV-associated proteins specifically involved in mitophagy and secretory autophagy. A set of proteins required for sequential steps of fission-induced mitophagy preferentially populated the CD81+/PD-L1+ IF EVs; including PINK1 and ARIH1 E3 ubiquitin ligase (required for Parkin-independent mitophagy), DRP1 and FIS1 (mitochondrial pinching), and VPS35, SEC22b, and Rab33b (vacuolar sorting). SLN immune cell populations could be massively remodeled by introducing hydrogel NPs which have a controlled release of T-cell and dendritic cell chemoattractant to the subcapsular sinus. NPs were successfully used to deliver concentrated packages of EVs subpopulations to the SLN. Introduction of the large CD81-/VEGF+/PD-L1- EV subpopulation (amphisome characteristics) to the SLN augmented tumor growth, angiogenesis, and metastasis, even when cytokine induction was used to remodel the SLN. In marked contrast, introduction of the CD81+/PD-L1+ EV subpopulation (containing mitophagy components) to the SLN in combination with NP release of chemoattractants, induced immune rejection of the syngeneic breast cancer, reducing tumor growth, and blocking metastasis. These findings demonstrate that different populations of EVs have opposite effects on cancer immune evasion at the level of the SLN and that EV-mediated immune suppression can be reversed by SLN remodeling to augment dendritic and CD8+ T cells.

Abstract
Abstract
Ovarian cancer is the deadliest cancer of the female reproductive system, with the majority of patients experiencing relapse on first-line platinum-based chemotherapies. Identifying potential targets for additional second-line therapies is critical for treating platinum-resistant ovarian cancer. To that end, the evolution of platinum resistance in a cell-based model of ovarian cancer was monitored via characterization of proteomic changes in cancer-derived extracellular vesicles (EVs) after progressive rounds of cisplatin treatment. The content of cancer-derived EVs was analyzed via reverse phase protein array, mass spectrometry, and Western blotting to identify pathways that could be targeted by second-line therapies. Several therapeutically relevant markers were upregulated, including phospho-EGFR (Y1068), multidrug transporter ABCE1, and PD-L1. Monoclonal antibody-based therapies (mAbs) targeting PD-1/PD-L1 have been deployed successfully as second-line treatments for a variety of cancers, but their success has yet to be translated to ovarian cancer. Current mAb-based immunotherapies suffer from several pitfalls including poor tissue penetration, a long-standing issue in ovarian cancer treatment. To offer an alternative to mAb-based immunotherapies, we developed a small interfering peptide consisting of a portion of the PD-L1 interface sequence. This lead peptide underwent several rounds of in silico optimization via molecular dynamics and modeling simulations to identify modifications that could improve affinity for PD-1 or stability in serum. When efficacy was assessed in vitro via Amplified Luminescent Proximity Homogeneous Assay screening, the modifications to the lead peptide were not shown to improve efficacy. However, serum stability studies indicated the modifications dramatically improved peptide stability, with detectable levels still quantifiable via mass spectrometry after 48 hours. The stabilized peptide, titled MN1.4, was chosen for further efficacy testing in cell-based models. A cisplatin-treated daughter line from the OVCAR8 high grade serous ovarian carcinoma cell line was created to model the effects of clinical platinum-based chemotherapy treatments on the most common ovarian cancer subtype. OVCAR8 cells were co-cultured in the presence of stimulated Jurkat T cells to measure markers of T cell activation, including IL-2, via ELISA after treatment with MN1.4 in the presence or absence of EVs derived from cisplatin-treated cells. This model allows for examination of the potential sensitization effects of first-line cisplatin treatment on PD-1/PD-L1 immunotherapy, and how cancer-derived EVs from cisplatin-treated cells can abrogate this effect. We conclude that exosomal PD-L1 may impair responses to PD-1/PD-L1 immunotherapy and should be considered when assessing the viability of this treatment option for ovarian cancer patients.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (S)-pseudotyped viruses are commonly used for quantifying antiviral drugs and neutralizing antibodies. Here, we describe the development of a hybrid alphavirus-SARS-CoV-2 (Ha-CoV-2) pseudovirion, which is a non-replicating SARS-CoV-2 virus-like particle composed of viral structural proteins (S, M, N, and E) and an RNA genome derived from a fast-expressing alphaviral vector. We validated Ha-CoV-2 for rapid quantification of neutralization antibodies, antiviral drugs, and viral variants. In addition, as a proof of concept, we used Ha-CoV-2 to quantify the neutralizing antibodies from an infected and vaccinated individual and found that the one-dose vaccination with Moderna mRNA-1273 greatly increased the anti-serum titer by approximately 6-fold. The post-vaccination serum can neutralize all nine variants tested. These results demonstrate that Ha-CoV-2 can be used as a robust platform for the rapid quantification of neutralizing antibodies against SARS-CoV-2 and its emerging variants.

Abstract
The efficacy of molecular targeted therapy depends on expression and enzymatic activity of the target molecules. As radiotherapy modulates gene expression and protein phosphorylation dependent on dose and fractionation, we analyzed the long-term effects of irradiation on the post-radiation efficacy of molecular targeted drugs. We irradiated prostate cancer cells either with a single dose (SD) of 10 Gy x-ray or a multifractionated (MF) regimen with 10 fractions of 1 Gy. Whole genome arrays and reverse phase protein microarrays were used to determine gene expression and protein phosphorylation. Additionally, we evaluated radiation-induced pathway activation with the Ingenuity Pathway Analysis software. To measure cell survival and sensitivity to clinically used molecular targeted drugs, we performed colony formation assays. We found increased activation of several pathways regulating important cell functions such as cell migration and cell survival at 24 h after MF irradiation or at 2 months after SD irradiation. Further, cells which survived a SD of 10 Gy showed a long-term upregulation and increased activity of multiple molecular targets including AKT, IGF-1R, VEGFR2, or MET, while HDAC expression was decreased. In line with this, 10 Gy SD cells were more sensitive to target inhibition with Capivasertib or Ipatasertib (AKTi), BMS-754807 (IGF-1Ri), or Foretinib (VEGFR2/METi), but less sensitive to Panobinostat or Vorinostat (HDACi). In summary, understanding the molecular short- and long-term changes after irradiation can aid in optimizing the efficacy of multimodal radiation oncology in combination with post-irradiation molecularly-targeted drug treatment and improving the outcome of prostate cancer patients.

Abstract
BACKGROUND Anti-programmed cell death protein 1 and programmed cell death ligand 1 (PD-L1) agents are broadly used in first-line and second-line treatment across different tumor types. While immunohistochemistry-based assays are routinely used to assess PD-L1 expression, their clinical utility remains controversial due to the partial predictive value and lack of standardized cut-offs across antibody clones. Using a high throughput immunoassay, the reverse phase protein microarray (RPPA), coupled with a fluorescence-based detection system, this study compared the performance of six anti-PD-L1 antibody clones on 666 tumor samples. METHODS PD-L1 expression was measured using five antibody clones (22C3, 28-8, CAL10, E1L3N and SP142) and the therapeutic antibody atezolizumab on 222 lung, 71 ovarian, 52 prostate and 267 breast cancers, and 54 metastatic lesions. To capture clinically relevant variables, our cohort included frozen and formalin-fixed paraffin-embedded samples, surgical specimens and core needle biopsies. Pure tumor epithelia were isolated using laser capture microdissection from 602 samples. Correlation coefficients were calculated to assess concordance between antibody clones. For two independent cohorts of patients with lung cancer treated with nivolumab, RPPA-based PD-L1 measurements were examined along with response to treatment. RESULTS Median-center PD-L1 dynamic ranged from 0.01 to 39.37 across antibody clones. Correlation coefficients between the six antibody clones were heterogeneous (range: -0.48 to 0.95) and below 0.50 in 61% of the comparisons. In nivolumab-treated patients, RPPA-based measurement identified a subgroup of tumors, where low PD-L1 expression equated to lack of response. CONCLUSIONS Continuous RPPA-based measurements capture a broad dynamic range of PD-L1 expression in human specimens and heterogeneous concordance levels between antibody clones. This high throughput immunoassay can potentially identify subgroups of tumors in which low expression of PD-L1 equates to lack of response to treatment.

Abstract
Background Because of their direct patient contact, healthcare workers (HCW) face an unprecedented risk of exposure to COVID-19. The aim of this study was to examine incidence of COVID-19 disease among asymptomatic HCW and community participants in Northern Virginia during 6 months of follow-up. Methods This is a prospective cohort study that enrolled healthy HCW and residents who never had a symptomatic COVID-19 infection prior to enrolment from the community in Northern Virginia from April to November 2020. All participants were invited to enrol in study, and they were followed at 2-, and 6-months intervals. Participants were evaluated by commercial chemiluminescence SARS-CoV-2 serology assays as part of regional health system and public health surveillance program to monitor the spread of COVID-19 disease. Findings Of a total of 1,819 asymptomatic HCW enrolled, 1,473 (96%) had data at two-months interval, and 1,323 (73%) participants had data at 6-months interval. At baseline, 21 (1.15%) were found to have prior COVID-19 exposure. At two-months interval, COVID-19 rate was 2.8% and at six months follow-up, the overall incidence rate increased to 4.8%, but was as high as 7.9% among those who belong to the youngest age group (20–29 years). Seroconversion rates in HCW were comparable to the seropositive rates in the Northern Virginia community. The overall incidence of COVID-19 in the community was 4.5%, but the estimate was higher among Hispanic ethnicity (incidence rate = 15.3%) potentially reflecting different socio-economic factors among the community participants and the HCW group. Using cross-sectional logistic regression and spatio-temporal mixed effects models, significant factors that influence the transmission rate among HCW include age, race/ethnicity, resident ZIP-code, and household exposure, but not direct patient contact. Interpretation In Northern Virginia, the seropositive rate of COVID-19 disease among HCW was comparable to that in the community.

Abstract
Background Circulating tumour DNA (ctDNA) is known as a tumour-specific personalised biomarker, but the mutation-selection criteria from heterogeneous tumours remain a challenge. Methods We conducted multiregional sequencing of 42 specimens from 14 colorectal tumours of 12 patients, including two double-cancer cases, to identify mutational heterogeneity to develop personalised ctDNA assays using 175 plasma samples. Results “Founder” mutations, defined as a mutation that is present in all regions of the tumour in a binary manner (i.e., present or absent), were identified in 12/14 tumours. In contrast, “truncal” mutations, which are the first mutation that occurs prior to the divergence of branches in the phylogenetic tree using variant allele frequency (VAF) as continuous variables, were identified in 12/14 tumours. Two tumours without founder and truncal mutations were hypermutators. Most founder and truncal mutations exhibited higher VAFs than “non-founder” and “branch” mutations, resulting in a high chance to be detected in ctDNA. In post-operative long-term observation for 10/12 patients, early relapse prediction, treatment efficacy and non-relapse corroboration were achievable from frequent ctDNA monitoring. Conclusions A single biopsy is sufficient to develop custom dPCR probes for monitoring tumour burden in most CRC patients. However, it may not be effective for those with hypermutated tumours.

Abstract
Background The lack of specificity and high degree of false positive and false negative rates when using mammographic screening for detecting early-stage breast cancer is a critical issue. Blood-based molecular assays that could be used in adjunct with mammography for increased specificity and sensitivity could have profound clinical impact. Our objective was to discover and independently verify a panel of candidate blood-based biomarkers that could identify the earliest stages of breast cancer and complement current mammographic screening approaches. Methods We used affinity hydrogel nanoparticles coupled with LC-MS/MS analysis to enrich and analyze low-abundance proteins in serum samples from 20 patients with invasive ductal carcinoma (IDC) breast cancer and 20 female control individuals with positive mammograms and benign pathology at biopsy. We compared these results to those obtained from five cohorts of individuals diagnosed with cancer in organs other than breast (ovarian, lung, prostate, and colon cancer, as well as melanoma) to establish IDC-specific protein signatures. Twenty-four IDC candidate biomarkers were then verified by multiple reaction monitoring (LC-MRM) in an independent validation cohort of 60 serum samples specifically including earliest-stage breast cancer and benign controls (19 early-stage (T1a) IDC and 41 controls). Results In our discovery set, 56 proteins were increased in the serum samples from IDC patients, and 32 of these proteins were specific to IDC. Verification of a subset of these proteins in an independent cohort of early-stage T1a breast cancer yielded a panel of 4 proteins, ITGA2B (integrin subunit alpha IIb), FLNA (Filamin A), RAP1A (Ras-associated protein-1A), and TLN-1 (Talin-1), which classified breast cancer patients with 100% sensitivity and 85% specificity (AUC of 0.93). Conclusions Using a nanoparticle-based protein enrichment technology, we identified and verified a highly specific and sensitive protein signature indicative of early-stage breast cancer with no false positives when assessing benign and inflammatory controls. These markers have been previously reported in cell-ECM interaction and tumor microenvironment biology. Further studies with larger cohorts are needed to evaluate whether this biomarker panel improves the positive predictive value of mammography for breast cancer detection.

Abstract
PURPOSE Antibody-dependent cell-mediated cytotoxicity (ADCC) is one mechanism of action of the monoclonal antibody (mAb) therapies trastuzumab and pertuzumab. Tyrosine kinase inhibitors (TKIs), like lapatinib, may have added therapeutic value in combination with mAbs through enhanced ADCC activity. Using clinical data, we examined the impact of lapatinib on HER2/EGFR expression levels and natural killer (NK) cell gene signatures. We investigated the ability of three TKIs (lapatinib, afatinib, and neratinib) to alter HER2/immune-related protein levels in preclinical models of HER2-positive (HER2+) and HER2-low breast cancer, and the subsequent effects on trastuzumab/pertuzumab-mediated ADCC. EXPERIMENTAL DESIGN Preclinical studies (proliferation assays, Western blotting, high content analysis, and flow cytometry) employed HER2+ (SKBR3 and HCC1954) and HER2-low (MCF-7, T47D, CAMA-1, and CAL-51) breast cancer cell lines. NCT00524303 provided reverse phase protein array-determined protein levels of HER2/pHER2/EGFR/pEGFR. RNA-based NK cell gene signatures (CIBERSORT/MCP-counter) post-neoadjuvant anti-HER2 therapy were assessed (NCT00769470/NCT01485926). ADCC assays utilized flow cytometry-based protocols. RESULTS Lapatinib significantly increased membrane HER2 levels, while afatinib and neratinib significantly decreased levels in all preclinical models. Single-agent lapatinib increased HER2 or EGFR levels in 10 of 11 (91%) tumor samples. NK cell signatures increased posttherapy (P = 0.03) and associated with trastuzumab response (P = 0.01). TKI treatment altered mAb-induced NK cell-mediated ADCC in vitro, but it did not consistently correlate with HER2 expression in HER2+ or HER2-low models. The ADCC response to trastuzumab and pertuzumab combined did not exceed either mAb alone. CONCLUSIONS TKIs differentially alter tumor cell phenotype which can impact NK cell-mediated response to coadministered antibody therapies. mAb-induced ADCC response is relevant when rationalizing combinations for clinical investigation.

Abstract
Babesiosis among humans is on the rise in North America. Current diagnostic assays for the screening of babesiosis require blood collection by venipuncture, which is an invasive method. Urine on the other hand is a desirable biospecimen for biomarker analysis of Babesia microti infections because it can be collected periodically and non-invasively. Our group uses a new class of biomarker harvesting nanocage technology, which, when combined with mass spectrometry (MS), can determine the presence of parasite proteins shed in different bodily fluids of mammalian hosts, including urine. Using the hamster model of babesiosis, our nanoparticle-MS approach identified several B. microti proteins in erythrocytes, plasma, and urine samples. Surface and secreted antigens previously shown to elicit host immune responses against the parasite were particularly abundant in erythrocytes and plasma compared to other proteins. Two of these antigens, BmSA1 and BMR1_03g00947, showed different localization patterns by immunofluorescence of infected erythrocytes. Hamster urine samples from parasitemic animals harbored lower numbers of B. microti proteins compared to erythrocytes and plasma, with glycolytic enzymes, cytoskeletal components, and chaperones being the most frequently detected proteins. By applying novel nanoparticle-MS methods, a high level of analytical sensitivity can be achieved to detect multiple B. microti proteins in blood and urine. This is generally difficult to obtain with other techniques due to the masking of parasite biomarkers by the complex biomolecular matrix of bodily fluids from the host.

Abstract
BACKGROUND During metastasis, tumor cells metastasize from primary tumors to distant organs via the circulatory and the lymphatic systems. There is a plethora of information about metastasis through the circulatory system, however not much information is available about the tumor cells dissemination through the lymphatic system or the lymphatic microenvironment that aids in this process in breast cancer metastasis. PURPOSE The study designed to examine the tumor-derived secretome in lymph before reaching the draining lymph nodes. METHODS Using a microsurgical technique, we have collected the lymph in transit from the primary tumor en route to the regional lymph node in animals with metastatic and non-metastatic mammary carcinoma and healthy controls. The lymph samples were subjected to LC-MS/MS analysis, bioinformatics, and pathway analysis. RESULTS The metastatic tumor-draining lymph before its entry into the closest regional lymph node contain 26 proteins with >175-folds in abundance compared to lymph from non-metastatic tumor-bearing animals. Among these proteins were biliverdin reductase B, heat shock protein, coagulation factor XIII, lymphocytes cytosol protein 1, and aldose reductase. These proteins were not identified in the lymph from healthy animals. Pathways analysis revealed that cadherin-mediated endocytosis, acute phase response, junction signaling, gap junction, VEGF singling, and PI3K/AKT singling pathways are overrepresented in the lymph from metastatic tumor-bearing compared to the lymph from non-metastatic tumor-bearing animals. Among the significantly up-regulated proteins in the lymph from metastatic tumor-bearing animals were proteins that identified in exosomes include heat shock protein, enolase 1 alpha, S100, and biliverdin reductase B. One of the proteins significantly down-regulated in lymph from animals with metastasis is Kininogen, a known metastasis inhibitor protein. CONCLUSION Proteins and exosomal proteins in lymph draining a metastatic tumor are different from those in lymph draining non-metastatic tumors, and these proteins involved in pathways that regulate tumor cells migration and invasion.

Abstract
PURPOSE We hypothesized that autophagy inhibition would increase response to chemotherapy in the preoperative setting for patients with pancreatic adenocarcinoma. We performed a randomized controlled trial to assess the autophagy inhibitor hydroxychloroquine in combination with gemcitabine and nab-paclitaxel. PATIENTS AND METHODS Participants with potentially resectable tumors were randomized to two cycles of nab-paclitaxel and gemcitabine (PG) alone or with hydroxychloroquine (PGH), followed by resection. The primary endpoint was histopathologic response in the resected specimen. Secondary clinical endpoints included serum CA 19-9 biomarker response and margin negative R0 resection. Exploratory endpoints included markers of autophagy, immune infiltrate, and serum cytokines. RESULTS Thirty-four patients in the PGH arm and 30 in the PG arm were evaluable for the primary endpoint. The PGH arm demonstrated statistically improved Evans grade histopathologic responses (P = 0.00016), compared with control. In patients with elevated CA 19-9, a return to normal was associated with improved overall and recurrence-free survival (P < 0.0001). There were no differences in serious adverse events between arms and chemotherapy dose number was equivalent. The PGH arm had greater evidence of autophagy inhibition in their resected specimens (increased SQSTM1, P = 0.027, as well as increased immune cell tumor infiltration, P = 0.033). Overall survival (P = 0.59) and relapse-free survival (P = 0.55) did not differ between the two arms. CONCLUSIONS The addition of hydroxychloroquine to preoperative gemcitabine and nab-paclitaxel chemotherapy in patients with resectable pancreatic adenocarcinoma resulted in greater pathologic tumor response, improved serum biomarker response, and evidence of autophagy inhibition and immune activity.

Abstract
Abstract
Background: ER- HER2+ BC is comprised of a heterogeneous mix of intrinsic BC subtypes which have differential responsiveness to preop HER2-directed therapies combined with chemotherapy. Patients (pts) with ER- HER2+ BC whose disease progressed while on or who had no response to preop HER2-directed therapy are uncommon and the mechanisms of resistance within this primary-refractory disease are unknown. We utilized RPPA-based protein pathway activation mapping to map the drug target signaling architecture in pts’ primary-refractory ER- HER2+ BCs to begin to assess mechanisms of resistance. Methods: Eight primary-refractory ER- HER2+ FFPE BC tissues obtained from 5 pts (preop biopsies n=4 and/or post-treatment surgical resection n=4) underwent laser capture microdissection to isolate pure tumor epithelium followed by RPPA-based analysis of the levels and/or activation/phosphorylation of approximately 130 key signaling proteins known to be involved in tumorigenesis and metastatic progression. Results: Pts were all treated with preop trastuzumab, pertuzumab, docetaxel, and carboplatin (TCHP) with no response and/or with progression of disease. Three pts also received preop doxorubicin/cyclophosphamide without response. RPPA-based analysis revealed that post-TCHP surgical samples had higher activation of a number of drug targets including receptor tyrosine kinases (RTK) such as MET and ALK, as well as HER family signaling proteins phospho-HER3 and phospho-EGFR compared to the matched pre-TCHP samples. Conclusions: In these ER- HER2+ BCs that were primary-refractory to preop TCHP, in those pts with patient-matched pre/post treatment samples, activation of several potential resistance pathways such as alternative RKT signaling as well as EGFR and HER3 signaling was observed. These data are hypothesis-generating and require exploration in additional ER- HER2+ primary-refractory tissues.

Abstract
PURPOSE To identify proteomic and genomic alterations in residual disease (RD) for human epidermal growth factor receptor 2 (HER2)-positive (HER2+) breast cancer (BC) after preoperative trastuzumab (H), lapatinib (L), or both (H+L) in combination with chemotherapy. PATIENTS AND METHODS Patients with stage II/III HER2+ BC (n = 100) were randomly assigned to preoperative treatment with H versus L 1,250mg versus H+L (L: 750 to 1,000 mg) plus 5-fluorouracil, epirubicin, and cyclophosphamide, followed by weekly paclitaxel. After receiving institutional review board–approved informed consent, targeted next-generation sequencing was performed on 20 patients’ formalin-fixed paraffin embedded tumors to characterize genomic alterations across 287 cancer-related genes. Reverse phase protein array (RPPA) analysis was performed on both the baseline biopsy and RD specimens, when available. RESULTS Two of 20 RD tissues were HER2 negative per next-generation sequencing; one sample had insufficient tissue. Of six pretreatment biopsy specimens, four were comutated with TP53 and PIK3CA. Of 17 HER2+ RD, seven specimens (41%) had PIK3CA mutations always comutated with TP53, and four (24%) also had concurrent CDK12 amplification. Overall, CDK12 amplification was observed in eight of the 17 (47%) HER2+ RD specimens. A total of 12 RD specimens (71%) had TP53 mutations. Although prevalence of individual TP53 and PIK3CA mutations was only modestly higher than published estimates for those in HER2+ primary BCs (55% and 32% for TP53 and PIK3CA, respectively), prevalence of these as comutations appeared higher (41%), compared with less than 10% in several series. On RPPA analysis of the RD tissue with comutations, the strongest Spearman ρ correlations were limited to EGFR and phospho-AKT (ρ, 0.999; P = .019) and phospho-mTOR and phospho-S6 ribosomal protein (ρ, 0.994; P = .048). CONCLUSION HER2-amplified RD tissue after preoperative H, L, or H+L plus chemotherapy was enriched for PIK3CA and TP53 comutations, and the RD tissue demonstrated activation of EGFR/AKT/mTOR signaling on RPPA.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive disease with limited and, very often, ineffective medical and surgical therapeutic options. The treatment of patients with advanced unresectable PDAC is restricted to systemic chemotherapy, a therapeutic intervention to which most eventually develop resistance. Recently, nab-paclitaxel (n-PTX) has been added to the arsenal of first-line therapies, and the combination of gemcitabine and n-PTX has modestly prolonged median overall survival. However, patients almost invariably succumb to the disease, and little is known about the mechanisms underlying n-PTX resistance. Using the conditionally reprogrammed (CR) cell approach, we established and verified continuously growing cell cultures from treatment-naïve patients with PDAC. To study the mechanisms of primary drug resistance, nab-paclitaxel-resistant (n-PTX-R) cells were generated from primary cultures and drug resistance was verified in vivo, both in zebrafish and in athymic nude mouse xenograft models. Molecular analyses identified the sustained induction of c-MYC in the n-PTX-R cells. Depletion of c-MYC restored n-PTX sensitivity, as did treatment with either the MEK inhibitor, trametinib, or a small-molecule activator of protein phosphatase 2a. IMPLICATIONS: The strategies we have devised, including the patient-derived primary cells and the unique, drug-resistant isogenic cells, are rapid and easily applied in vitro and in vivo platforms to better understand the mechanisms of drug resistance and for defining effective therapeutic options on a patient by patient basis.

Abstract
PURPOSE OF REVIEW We discuss recent advancements in structural biology methods for investigating sites of protein-protein interactions. We will inform readers outside the field of structural biology about techniques beyond crystallography, and how these different technologies can be utilized for drug development. RECENT FINDINGS Advancements in cryo-electron microscopy (cryoEM) and micro-electron diffraction (microED) may change how we view atomic resolution structural biology, such that well-ordered macrocrystals of protein complexes are not required for interface identification. However, some drug discovery applications, such as lead peptide compound generation, may not require atomic resolution; mass spectrometry techniques can provide an expedited path to generation of lead compounds. New crosslinking compounds, more user-friendly data analysis, and novel protocols such as protein painting can advance drug discovery programs, even in the absence of atomic resolution structural data. Finally, artificial intelligence and machine learning methods, while never truly replacing experimental methods, may provide rational ways to stratify potential druggable regions identified with mass spectrometry into higher and lower priority candidates. SUMMARY Electron diffraction of nanocrystals combines the benefits of both x-ray diffraction and cryoEM, and may prove to be the next generation of atomic resolution protein-protein interface identification. However, in situations such as peptide drug discovery, mass spectrometry techniques supported by advancements in computational methods will likely prove sufficient to support drug discovery efforts. In addition, these methods can be significantly faster than any crystallographic or cryoEM methods for identification of interacting regions.

Abstract
Human Immunodeficiency Virus-1 (HIV-1) is the causative agent of Acquired Immunodeficiency Syndrome (AIDS), infecting nearly 37 million people worldwide. Currently, there is no definitive cure, mainly due to HIV-1's ability to enact latency. Our previous work has shown that exosomes, a small extracellular vesicle, from uninfected cells can activate HIV-1 in latent cells, leading to increased mostly short and some long HIV-1 RNA transcripts. This is consistent with the notion that none of the FDA-approved antiretroviral drugs used today in the clinic are transcription inhibitors. Furthermore, these HIV-1 transcripts can be packaged into exosomes and released from the infected cell. Here, we examined the differences in protein and nucleic acid content between exosomes from uninfected and HIV-1-infected cells. We found increased cyclin-dependent kinases, among other kinases, in exosomes from infected T-cells while other kinases were present in exosomes from infected monocytes. Additionally, we found a series of short antisense HIV-1 RNA from the 3' LTR that appears heavily mutated in exosomes from HIV-1-infected cells along with the presence of cellular noncoding RNAs and cellular miRNAs. Both physical and functional validations were performed on some of the key findings. Collectively, our data indicate distinct differences in protein and RNA content between exosomes from uninfected and HIV-1-infected cells, which can lead to different functional outcomes in recipient cells.

Abstract
Abstract
PURPOSE: This study aimed to perform molecular profiling of the heterogeneous histological and mutational background of primary adenocarcinoma of the stomach for pre- and post-operational tumor burden monitoring using circulating tumor DNA (ctDNA).
METHODS: Ten patients with gastric adenocarcinoma who underwent surgical resection for clinical Stage IB or higher were included. Multi-region samples (three sites) per resected specimen were used for cancer cellulality estimation, a 151-gene ClearSeq panel sequencing on Next Generation Sequencer (NGS), and proteomic profiling with 294 proteins using reverse-phase protein arrays (RPPAs). The ctDNA level was evaluated by digital PCR (dPCR) using 25 originally-designed sets with the Hypercool Primer & ProbeTM technology based on mutations of individual tumors. With the median follow-up of 808 days, a total of 187 serial plasma samples were examined for ctDNA.
RESULTS: A total of 103 mutations were detected in 30 regions from 10 tumors. Twenty founder mutations (i.e., mutations found in all three regions) were observed in eight tumors whereas two tumors had only non-founder mutations. Twenty-three and 60 non-founder mutations were detected in two regions and one region per tumor, respectively. Variant allele frequencies (VAFs) of founder mutations were higher than those of non-founder mutations (31.2% vs 14.5%; p < 0.01) in primary tumors. With sample regions in which mutations were not detected in trio by NGS, non-founder mutations could be detected by dPCR at low VAFs (ranging from 0.02 to 2.2%) in 95% (19/20) regions. In preoperative patient plasma, ctDNA was detected in 30% (3/10) patients (with a mean VAF of 0.59%). The rate of preoperative ctDNA detection was lower than that of esophageal squamous cell cancer (24/26, 92.3%) and colorectal cancer (10/12, 83.3%) patients. With respect to the tumor stromal effect to ctDNA, no ctDNA was detected in three cases of scirrhous type cancers (0/3, 0%), whereas three of six cases of the other stromal types (3/6, 50%) showed detectable ctDNA (VAF>0.03%). In two relapsed cases with peritoneal dissemination, the elevation of ctDNA was not apparent even at the time of diagnosis of the relapse by CT scan. Among 42 gene-protein matched pairs, the level of proteins did not seem to predict the coding gene mutation. However, tumors with TP53 mutations had significantly higher levels of p53 than those with the wild-type, which was likely due to protein stabilization (p = 0.0004).
CONCLUSIONS: Detecting ctDNA in gastric cancer patients may not be as feasible as in other gastrointestinal cancer patients likely due to the heterogeneous histological and mutational background. If applicable, founder mutations are the most suitable marker for detection and monitoring ctDNA. Mutations in the primary tumor itself did not appear to predict protein levels except for TP53.

Abstract
Abstract
Protein-protein interactions are thought to be the next frontier in drug discovery. However, there are several well-known challenges facing development of protein-protein interaction (PPI) inhibitors that lead to slow development in the field, including difficulty identifying PPIs and difficulty designing small molecule inhibitors of relatively flat, featureless PPIs. We address these difficulties with the development of a novel method of discovering PPI hotspots, called protein painting. This technique relies on non-covalent labeling of solvent- accessible protein surfaces using small molecular dyes optimized for protein binding. The dyes block access to trypsin cleavage sites, allowing for digestion only of undyed interface regions following denaturation of the protein complex. Interface regions can be identified using mass spectrometry and used as target sequences for drug development. Here we introduce new dye chemistries and elucidate their mechanism of protein binding for the first time. This allows for rapid identification of functionally-relevant hotspots without the need to screen many dye chemistries to optimize surface coverage of the protein complex. We applied this method to elucidate functional hotspots for immmuno-oncology targets PD-1 and PD-L1 and Hippo pathway targets YAP2 and tight junction protein ZO-1. To further functionally validate the hotspot regions identified, we focused on the case study of PD-1 and PD-L1. We discovered a hotspot of PD-1 Lys 78 in the protein-protein interface, and rationally designed a series of 8 peptide inhibitors to target this hotspot. The most active peptide YRCMISYGGADYKRITV derived from PD-L1 disrupted the PD-1/PD-L1 complex with an IC50 of 5.07 µM. The predicted binding site of this peptide on PD-1 overlaps the binding site of therapeutic anti-PD-1 antibody pembrolizumab; crystal structures of pembrolizumab and PD-1 show hydrogen bonding between the antibody and our identified hotspot Lys 78. Furthermore, we prepared a cyclized analog peptide CYRAMISYGGADYKRITC by disulfide bond stapling to increase peptide stability and found that this did not significantly reduce inhibitor potency, with an IC50 of 8.02 µM. Taken together, this data suggests a specific region of PD-1 found within the larger PD-1/PD-L1 interface that may serve as a target for development of next generation small molecule PD-1/PD-L1 inhibitors. By focusing drug discovery efforts against only the PPI hotspot regions, we may accelerate drug development against these difficult targets.

Abstract
Protein-protein interactions lie at the heart of many biological processes and therefore represent promising drug targets. Despite this opportunity, identification of protein-protein interfaces remains challenging. We have previously developed a method that relies on coating protein surfaces with small-molecule dyes to discriminate between solvent-accessible protein surfaces and hidden interface regions. Dye-bound, solvent-accessible protein regions resist trypsin digestion, whereas hidden interface regions are revealed by denaturation and sequenced by MS. The small-molecule dyes bind promiscuously and with high affinity, but their binding mechanism is unknown. Here, we report on the optimization of a novel dye probe used in protein painting, Fast Blue B + naphthionic acid, and show that its affinity for proteins strongly depends on hydrophobic moieties that we call here "hydrophobic clamps." We demonstrate the utility of this probe by sequencing the protein-protein interaction regions between the Hippo pathway protein Yes-associated protein 2 (YAP2) and tight junction protein 1 (TJP1 or ZO-1), uncovering interactions via the known binding domain as well as ZO-1's MAGUK domain and YAP's N-terminal proline-rich domain. Additionally, we demonstrate how residues predicted by protein painting are present exclusively in the complex interface and how these residues may guide the development of peptide inhibitors using a case study of programmed cell death protein 1 (PD-1) and programmed cell death 1 ligand 1 (PD-L1). Inhibitors designed around the PD-1/PD-L1 interface regions identified via protein painting effectively disrupted complex formation, with the most potent inhibitor having an IC50 of 5 μm.

Abstract
Bone tissue is critically lagging behind soft tissues and biofluids in our effort to advance precision medicine. The main challenges have been accessibility and the requirement for deleterious decalcification processes that impact the fidelity of diagnostic histomorphology and hinder downstream analyses such as fluorescence in-situ hybridization (FISH). We have developed an alternative fixation chemistry that simultaneously fixes and decalcifies bone tissue. We compared tissue morphology, immunohistochemistry (IHC), cell signal phosphoprotein analysis, and FISH in 50 patient matched primary bone cancer cases that were either formalin fixed and decalcified, or theralin fixed with and without decalcification. Use of theralin improved tissue histomorphology, whereas overall IHC was comparable to formalin fixed, decalcified samples. Theralin-fixed samples showed a significant increase in protein and DNA extractability, supporting technologies such as laser-capture microdissection and reverse phase protein microarrays. Formalin-fixed bone samples suffered from a fixation artifact where protein quantification of β-actin directly correlated with fixation time. Theralin-fixed samples were not affected by this artifact. Moreover, theralin fixation enabled standard FISH staining in bone cancer samples, whereas no FISH staining was observed in formalin-fixed samples. We conclude that the use of theralin fixation unlocks the molecular archive within bone tissue allowing bone to enter the standard tissue analysis pipeline. This will have significant implications for bone cancer patients, in whom personalized medicine has yet to be implemented.

Abstract
Proteomics of Babesia microti has lagged behind other apicomplexans despite recent genome and transcriptome studies. Here, we used a combination of nanotechnology and mass spectrometry to provide a proteomic profile of B. microti acute infection. We identified ∼500 parasite proteins in blood with functions such as transport, carbohydrate and energy metabolism, proteolysis, DNA and RNA metabolism, signaling, translation, lipid biosynthesis, and motility and invasion. We also identified surface antigens with roles in the immune response to the parasite. This first evaluation of the B. microti proteome in erythrocytes provides information for the study of intracellular survival and development of diagnostic tools using mass spectrometry.

Abstract
An accurate urine test for pulmonary tuberculosis (TB), affecting 9.6 million patients worldwide, is critically needed for surveillance and treatment management. Past attempts failed to reliably detect the mycobacterial glycan antigen lipoarabinomannan (LAM), a marker of active TB, in HIV-negative, pulmonary TB–infected patients’ urine (85% of 9.6 million patients). We apply a copper complex dye within a hydrogel nanocage that captures LAM with very high affinity, displacing interfering urine proteins. The technology was applied to study pretreatment urine from 48 Peruvian patients, all negative for HIV, with microbiologically confirmed active pulmonary TB. LAM was quantitatively measured in the urine with a sensitivity of >95%and a specificity of >80% (n = 101) in a concentration range of 14 to 2000 picograms per milliliter, as compared to non-TB, healthy and diseased, age-matched controls (evaluated by receiver operating characteristic analysis; area under the curve, 0.95; 95% confidence interval, 0.9005 to 0.9957). Urinary LAM was elevated in patients with a higher mycobacterial burden (n = 42), a higher proportion of weight loss (n = 37), or cough (n = 50). The technology can be configured in a variety of formats to detect a panel of previously undetectable very-low-abundance TB urinary analytes. Eight of nine patients who were smear-negative and culture-positive for TB tested positive for urinary LAM. This technology has broad implications for pulmonary TB screening, transmission control, and treatment management for HIV-negative patients.

Abstract
Introduction: Recent studies indicated tumors may be comprised of heterogeneous molecular subtypes and incongruent molecular portraits may emerge if different areas of the tumor are sampled. This study explored the impact of intra-tumoral heterogeneity in terms of activation/phosphorylation of FDA approved drug targets and downstream kinase substrates. Material and methods: Two independent sets of liver metastases from colorectal cancer were used to evaluate protein kinase-driven signaling networks within different areas using laser capture microdissection and reverse phase protein array. Results: Unsupervised hierarchical clustering analysis indicated that the signaling architecture and activation of the MAPK and AKT-mTOR pathways were consistently maintained within different regions of the same biopsy. Intra-patient variability of the MAPK and AKT-mTOR pathway were <1.06 fold change, while inter-patients variability reached fold change values of 5.01. Conclusions: Protein pathway activation mapping of enriched tumor cells obtained from different regions of the same tumor indicated consistency and robustness independent of the region sampled. This suggests a dominant protein pathway network may be activated in a high percentage of the tumor cell population. Given the genomic intra-tumoral variability, our data suggest that protein/phosphoprotein signaling measurements should be integrated with genomic analysis for precision medicine based analysis.

Abstract
BACKGROUND Stromal gene expression patterns predict patient outcomes in colorectal cancer. TRIM28 is a transcriptional co-repressor that regulates an abundance of genes through the KRAB domain family of transcription factors. We have previously shown that stromal expression of TRIM28 is a marker of disease relapse and poor survival in colorectal cancer. Here, we perform differential epithelium-stroma proteomic network analyses to characterize signaling pathways associated with TRIM28 within the tumor microenvironment. METHODS Reverse phase protein arrays were generated from laser capture micro-dissected carcinoma and stromal cells from fresh frozen colorectal cancer tissues. Phosphorylation and total protein levels were measured for 30 cancer-related signaling pathway endpoints. Strength and direction of associations between signaling endpoints were identified using Spearman's rank-order correlation analysis and compared to TRIM28 levels. Expression status of TRIM28 in tumor epithelium and stromal fibroblasts was assessed using IHC in formalin fixed tissue and the epithelium to stroma protein expression ratio method. RESULTS We found distinct proteomic networks in the epithelial and stromal compartments which were linked to expression levels of TRIM28. Low levels of TRIM28 in tumor stroma (high epithelium: stroma ratio) were found in 10 out of 19 cases. Upon proteomic network analyses, these stromal high ratio cases revealed moderate signaling pathway similarity exemplified by 76 significant Spearman correlations (ρ ≥ 0.75, p ≤ 0.01). Furthermore, low levels of stromal TRIM28 correlated with elevated MDM2 levels in tumor epithelium (p = 0.01) and COX-2 levels in tumor stroma (p = 0.002). Low TRIM28 epithelium to stroma ratios were associated with elevated levels of caspases 3 and 7 in stroma (p = 0.041 and p = 0.036) and an increased signaling pathway similarity in stromal cells with 81 significant Spearman correlations (ρ ≥ 0.75, p ≤ 0.01). CONCLUSIONS By dissecting TRIM28-associated pathways in stromal fibroblasts and epithelial tumor cells, we performed comprehensive proteomic analyses of molecular networks within the tumor microenvironment. We found modulation of several signaling pathways associated with TRIM28, which may be attributed to the pleiotropic properties of TRIM28 through its translational suppression of the family of KRAB domain transcription factors in tumor stromal compartments.

Abstract
Implementing targeted drug therapy in radio-oncologic treatment regimens has greatly improved the outcome of cancer patients. However, the efficacy of molecular targeted drugs such as inhibitory antibodies or small molecule inhibitors essentially depends on target expression and activity, which both can change during the course of treatment. Radiotherapy has previously been shown to activate prosurvival pathways, which can help tumor cells to adapt and thereby survive treatment. Therefore, we aimed to identify changes in signaling induced by radiation and evaluate the potential of targeting these changes with small molecules to increase the therapeutic efficacy on cancer cell survival. Analysis of "The Cancer Genome Atlas" database disclosed a significant overexpression of AKT1, AKT2, and MTOR genes in human prostate cancer samples compared with normal prostate gland tissue. Multifractionated radiation of three-dimensional-cultured prostate cancer cell lines with a dose of 2 Gy/day as a clinically relevant schedule resulted in an increased protein phosphorylation and enhanced protein-protein interaction between AKT and mTOR, whereas gene expression of AKT, MTOR, and related kinases was not altered by radiation. Similar results were found in a xenograft model of prostate cancer. Pharmacologic inhibition of mTOR/AKT signaling after activation by multifractionated radiation was more effective than treatment prior to radiotherapy. Taken together, our findings provide a proof-of-concept that targeting signaling molecules after activation by radiotherapy may be a novel and promising treatment strategy for cancers treated with multifractionated radiation regimens such as prostate cancer to increase the sensitivity of tumor cells to molecular targeted drugs.

Abstract
Diagnosis of clinical toxoplasmosis remains a challenge, thus limiting the availability of human clinical samples. Though murine models are an approximation of human response, their definitive infection status and tissue availability make them critical to the diagnostic development process. Hydrogel mesh nanoparticles were used to concentrate antigen to detectable levels for mass spectrometry. Seven Toxoplasma gondii isolates were used to develop a panel of potential peptide sequences for detection by parallel reaction monitoring (PRM) mass spectrometry. Nanoparticles were incubated with decreasing concentrations of tachyzoite lysate to explore the limits of detection of PRM. Mice whose toxoplasmosis infection status was confirmed by quantitative real-time PCR had urine tested by PRM after hydrogel mesh concentration for known T. gondii peptides. Peptides from GRA1, GRA12, ROP4, ROP5, SAG1, and SAG2A proteins were detected by PRM after nanoparticle concentration of urine, confirming detection of T. gondii antigen in the urine of an infected mouse.

Abstract
Abstract
The PINC trial (NCT01023477) examined the dosage efficacy of oral chloroquine (CQ), an autophagy inhibitor, as a neoadjuvant therapy to reduce the volume, cause regression and decrease the recurrence of breast ductal carcinoma in situ (DCIS), for any grade or ER/PR/Her2 status. Study Objectives: Establish the safety of preventive doses of chloroquine in patients receiving external beam radiation. Elucidate functional molecular and cellular impacts of in vivo autophagy pathway treatment for DCIS. Study the impact of autophagy inhibitors on the MRI characteristics of DCIS lesions. Study the molecular cytogenetic profile of DCIS lesions before and after therapy. This trial implemented a general strategy to accelerate the pace of community-based translational research. Technology for providing immediate feedback on the therapeutic efficacy at the molecular level can be broadly extended to other trials. Methodology: 12 patients diagnosed with DCIS (any grade or ER/PR/Her2 status) were enrolled and randomly assigned to receive CQ at 250mg/week (n=5) or 500mg/week (n=7) for 4 weeks, followed by standard of care surgical therapy. MRI was performed before/after CQ treatment. DCIS spheroid forming cells were isolated and propagated from fresh human DCIS lesions. DCIS cells were characterized by organ culture, xenograft transplantation, molecular cytogenetics, and 59 cell signaling kinases were quantified by Reverse Phase Protein Microarrays.
Results: 12 patients completed 4 weeks of CQ treatment prior to surgical excision of their DCIS lesion, with 1 yr follow-up information. CQ treatment reduced PCNA proliferation index in DCIS lesions compared to untreated controls (p=0.001) and inhibited autophagic flux (LC3B positive puncta by IHC). CQ reduced the number of mammospheres in organoid culture without altering copy number variation. Xenograft transplants in NOD/SCID mouse mammary fat pads failed to generate tumors (n=4). 7/12 patients exhibited a reduction in lesion diameter by MRI, 3/12 patients exhibited no measurable change, and 2/12 had a slight increase. Calcium export channel protein (PMCA2) co-localized with 3+ HER2 positive DCIS lesions. Tumor infiltrating macrophages migrated into DCIS ducts following CQ therapy compared to controls (p=0.006). Conclusion: Oral chloroquine, as anti-autophagy therapy, generates a measurable reduction in proliferation of DCIS lesions and enhances immune cell migration into the duct.

Abstract
Despite over 60 years of research on antiviral drugs, very few are FDA approved to treat acute viral infections. Rift Valley fever virus (RVFV), an arthropod borne virus that causes hemorrhagic fever in severe cases, currently lacks effective treatments. Existing as obligate intracellular parasites, viruses have evolved to manipulate host cell signaling pathways to meet their replication needs. Specifically, translation modulation is often necessary for viruses to establish infection in their host. Here we demonstrated phosphorylation of p70 S6 kinase, S6 ribosomal protein, and eIF4G following RVFV infection in vitro through western blot analysis and in a mouse model of infection through reverse phase protein microarrays (RPPA). Inhibition of p70 S6 kinase through rapamycin treatment reduced viral titers in vitro and increased survival and mitigated clinical disease in RVFV challenged mice. Additionally, the phosphorylation of p70 S6 kinase was decreased following rapamycin treatment in vivo. Collectively these data demonstrate modulating p70 S6 kinase can be an effective antiviral strategy.

Abstract
Abstract
Background: While genomic alterations are central players in tumor progression, proteins are the targets for precision therapy. The degree by which “actionable” genomic alterations translate into activated/altered proteins and pathway is still under investigation. Using a multi-OMIC approach from the SideOut 2 metastatic breast cancer (MBC) trial, this study explored the concordance between selected “actionable” genomic alterations and protein expression/activation.
Methods: Snap frozen biopsies from 29 MBC patients enrolled in a prospective phase II trial were used for this analysis. Exome WES and RNASeq data was processed using an in-house developed pipeline and identified amplification of CCND1 (6/29), FGFR1 (4/29), and FGF 3, 4, 5, and 19 (4/29) as some of most frequent “actionable” genomic alterations in our MBC cohort. Signaling analysis of the 29 cases was performed using Reverse Phase Protein Microarray coupled with Laser Capture Microdissection. Protein expression/phosphorylation was measured in a continuous scale and classified based on quartile distribution. Concordance between CCND1 amplification and Cyclin D1 expression, along with the activation of FOXM1 T600 and Rb S780, was explored. Amplification of the FGFR1 locus or its ligands was correlated with the level of activation/phosphorylation of FGFR1 Y653/654.
Results: While Cyclin D1 protein expression was greater than the population mean for 4/6 (67%) patients with CCND1 amplification, only 2/6 (33%) patients with CCND1 amplification had Cyclin D1 level within the top quartile of the population (n=29). FOXM1 T600 activation was independent from CCND1 amplification, with high levels of FOXM1 T600 predominantly in the CCND1 wild-type population. Only 1/6 (17%) patients with CCND1 amplification had FOXM1 T600 level similar to the top quartile of the population while a second patient was above the population median. Activation of Rb S780 was above the population median, but below the top quartile, in 2/6 (33%) CCND1 amplified patients. Similarly, none of the patients with activation of FGFR Y653/654 equal to the top quartile harbored an FGFR1 amplification. Only 1/4 (25%) patients carrying an FGFR1 amplification had an activation of FGFR Y653/654 above the population median. Similarly, 1/4 (25%) patients with FGF ligand amplification showed FGFR Y653/654 level within the top quartile while three patients had FGFR Y653/654 activation below the population median. No significant results were found between proteomic (below/above the median) and genomic characteristics by Fisher test (p>0.05).
Conclusion: Molecular genotyping of “actionable” cancer targets alone may be insufficient in predicting whether the actual drug target protein is expressed and/or activated in any given patient's tumor. Although these results need further validation, the combination of genomic and proteomic data may represent a more informative approach for identifying real molecular drivers of individual lesions as well as “actionable” protein/phosphoprotein targets in the absence of genomic events. Multi-OMIC approaches may lead to more effective stratification in precision medicine trials.

Abstract
Prostate cancer is the second most common cancer in men worldwide. Gleason grading is an important predictor of prostate cancer outcomes and is influential in determining patient treatment options. Clinical decisions based on a Gleason score of 7 are difficult as the prognosis for individuals diagnosed with Gleason 4+3 cancer is much worse than for those diagnosed with Gleason 3+4 cancer. Laser capture microdissection (LCM) is a highly precise method to isolate specific cell populations or discrete microregions from tissues. This report undertook a detailed molecular characterization of the tumor microenvironment in prostate cancer to define the proteome in the epithelial and stromal regions from tumor foci of Gleason grades 3 and 4. Tissue regions of interest were isolated from several Gleason 3+3 and Gleason 4+4 tumors using telepathology to leverage specialized pathology expertise to support LCM. Over 2,000 proteins were identified following liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis of all regions of interest. Statistical analysis revealed significant differences in protein expression (>100 proteins) between Gleason 3 and Gleason 4 regions-in both stromal and epithelial compartments. A subset of these proteins has had prior strong association with prostate cancer, thereby providing evidence for the authenticity of the approach. Finally, validation of these proteins by immunohistochemistry has been obtained using an independent cohort of prostate cancer tumor specimens.Implications: This unbiased strategy provides a strong foundation for the development of biomarker protein panels with significant diagnostic and prognostic potential.

Abstract
The cross-talk between tumor epithelium and surrounding stromal/immune microenvironment is essential to sustain tumor growth and progression and provides new opportunities for the development of targeted treatments focused on disrupting the tumor ecology. Identification of novel approaches to study these interactions is of primary importance. Using laser capture microdissection (LCM) coupled with reverse phase protein microarray (RPPA) based protein signaling activation mapping we explored the molecular interconnection between tumor epithelium and surrounding stromal microenvironment in 18 prostate cancer (PCa) specimens. Four specimen-matched cellular compartments (normal-appearing epithelium and its adjacent stroma, and malignant epithelium and its adjacent stroma) were isolated for each case. The signaling network analysis of the four compartments unraveled a number of molecular mechanisms underlying the communication between tumor cells and stroma in the context of the tumor microenvironment. In particular, differential expression of inflammatory mediators like IL-8 and IL-10 by the stroma cells appeared to modulate specific cross-talks between the tumor cells and surrounding microenvironment.

Abstract
Abstract
Background: The identification of organ-specific targetable signatures may help design more effective treatment for patients with metastatic breast cancer (MBC). We took a multi-OMIC approach to assess whether the AKT-mTOR pathway is globally activated during metastatic progression or whether it represents an organ-specific target.
Methods: Snap frozen biopsies from 25 MBC patients enrolled in a prospective phase II trial were used. Sites of metastasis were classified as liver (n=8) and others (n=17), the latter including cutaneous, lung, lymph nodes, and intra-abdominal lesions. Signaling analysis of the 25 cases was performed using Reverse Phase Protein Microarray (RPPA) coupled with Laser Capture Microdissection. Activation of the AKT-mTOR pathway was quantified as phosphorylation of AKT (S473) and the mTOR target p70S6 (T389). Matched exome (WES) and RNASeq data were available for 17 of 25 patients, five with liver metastases. Sequencing data was processed using an in-house developed pipeline to identify somatic events including coding mutations, copy number alterations, gene fusions, and differential expression. Activation of the AKT-mTOR pathway and sequencing data were compared between hepatic and non-hepatic lesions using an integrated RPPA and genomic approach.
Results: Among liver metastases, AKT was activated in 4 of the 8 (50.0%) patients, while 6 of the 8 cases (75.0%) showed activation of p70S6. Sequencing data revealed mutation of PIK3CA in 4 of the 5 liver metastases (80.0%). Three of the PIK3CA mutated specimens with catalytic domain mutations (codons 1023 and 147) demonstrated co-activation of AKT and p70S6, while the fourth case, containing a helical domain mutation (E542K), had activation of p70S6 only. The PIK3CA wild-type liver metastasis demonstrated low activation of AKT and p70S6. For non-hepatic metastases AKT was activated in 2 of the 17 cases (11.8%) and p70S6 in 5 of the 17 patients (29.4%).
Discussion: Although these results need further validation, activation of the AKT-mTOR pathway appears to be a hepatic specific signature in MBC and could be used for the selection of targeted agents for hepatic lesions.

Abstract
OBJECTIVE To display images of breast cancer from a dedicated breast CT using Depth 3-Dimensional (D3D) augmented reality. METHODS A case of breast cancer imaged using contrast-enhanced breast CT (Computed Tomography) was viewed with the augmented reality imaging, which uses a head display unit (HDU) and joystick control interface. RESULTS The augmented reality system demonstrated 3D viewing of the breast mass with head position tracking, stereoscopic depth perception, focal point convergence and the use of a 3D cursor and joy-stick enabled fly through with visualization of the spiculations extending from the breast cancer. CONCLUSION The augmented reality system provided 3D visualization of the breast cancer with depth perception and visualization of the mass's spiculations. The augmented reality system should be further researched to determine the utility in clinical practice.
