Abstract
Although most patients with multiple myeloma respond to treatment initially, therapy resistance develops almost invariably and only a subset of patients show durable responses to immunomodulatory (IMiD) therapies. While the immune microenvironment has been extensively studied in myeloma patients, its composition is currently not used as prognostic markers in clinical routine. We hypothesized that the outcome of immune signaling pathway engagement can be highly variable, depending on which two cellular populations participate in this interaction. This would have important prognostic and therapeutic implications, suggesting that it is crucial for immune pathways to be targeted in a specific cellular context. To test this hypothesis, we investigated a cohort of 27 patients with newly diagnosed multiple myeloma. We examined the complex regulatory networks within the immune compartment and their impact on disease progression. Analysis of immune cell composition and expression profiles revealed significant differences in the B cell compartment associated with treatment response. Transcriptional states in patients with short time to progression demonstrated an enrichment of pathways promoting B cell differentiation and inflammatory responses, which may indicate immune dysfunction. Importantly, the analysis of molecular interactions within the immune microenvironment highlights the dual role of signaling pathways, which can either be associated with good or poor prognosis depending on the cell types involved. Our findings therefore argue that therapeutic strategies targeting ligand-receptor interactions should take into consideration the composition of the microenvironment and the specific cell types involved in molecular interactions.

Abstract
Chimeric antigen receptor (CAR) engineering of natural killer (NK) cells is promising, with early-phase clinical studies showing encouraging responses. However, the transcriptional signatures that control the fate of CAR-NK cells after infusion and factors that influence tumor control remain poorly understood. We performed single-cell RNA sequencing and mass cytometry to study the heterogeneity of CAR-NK cells and their in vivo evolution after adoptive transfer, from the phase of tumor control to relapse. Using a preclinical model of noncurative lymphoma and samples from a responder and a nonresponder patient treated with CAR19/IL-15 NK cells, we observed the emergence of NK cell clusters with distinct patterns of activation, function, and metabolic signature associated with different phases of in vivo evolution and tumor control. Interaction with the highly metabolically active tumor resulted in loss of metabolic fitness in NK cells that could be partly overcome by incorporation of IL-15 in the CAR construct.

Abstract
Interrogation of cell-free DNA (cfDNA) represents an emerging approach to non-invasively estimate disease burden in multiple myeloma (MM). Here, we examined low-pass whole genome sequencing (LPWGS) of cfDNA for its predictive value in relapsed/ refractory MM (RRMM). We observed that cfDNA positivity, defined as ≥10% tumor fraction by LPWGS, was associated with significantly shorter progression-free survival (PFS) in an exploratory test cohort of 16 patients who were actively treated on diverse regimens. We prospectively determined the predictive value of cfDNA in 86 samples from 45 RRMM patients treated with elotuzumab, pomalidomide, bortezomib, and dexamethasone in a phase II clinical trial (NCT02718833). PFS in patients with tumor-positive and -negative cfDNA after two cycles of treatment was 1.6 and 17.6 months, respectively (HR 7.6, P < 0.0001). Multivariate hazard modelling confirmed cfDNA as independent risk factor (HR 96.6, P = 6.92e-05). While correlating with serum-free light chains and bone marrow, cfDNA additionally discriminated patients with poor PFS among those with the same response by IMWG criteria. In summary, detectability of MM-derived cfDNA, as a measure of substantial tumor burden with therapy, independently predicts poor PFS and may provide refinement for standard-of-care response parameters to identify patients with poor response to treatment earlier than is currently feasible.

Abstract
While there is extensive evidence for genetic variation as a basis for treatment resistance, other sources of variation result from cellular plasticity. Using multiple myeloma as an example of an incurable lymphoid malignancy, we show how cancer cells modulate lineage restriction, adapt their enhancer usage and employ cell-intrinsic diversity for survival and treatment escape. By using single-cell transcriptome and chromatin accessibility profiling, we show that distinct transcriptional states co-exist in individual cancer cells and that differential transcriptional regulon usage and enhancer rewiring underlie these alternative transcriptional states. We demonstrate that exposure to standard treatment further promotes transcriptional reprogramming and differential enhancer recruitment while simultaneously reducing developmental potential. Importantly, treatment generates a distinct complement of actionable immunotherapy targets, such as CXCR4, which can be exploited to overcome treatment resistance. Our studies therefore delineate how to transform the cellular plasticity that underlies drug resistance into immuno-oncologic therapeutic opportunities.

Abstract
PURPOSE Although remarkably effective in some patients, precision medicine typically induces only transient responses despite initial absence of resistance-conferring mutations. Using BRAF-mutated myeloma as a model for resistance to precision medicine we investigated if BRAF-mutated cancer cells have the ability to ensure their survival by rapidly adapting to BRAF inhibitor treatment. EXPERIMENTAL DESIGN Full-length single-cell RNA (scRNA) sequencing (scRNA-seq) was conducted on 3 patients with BRAF-mutated myeloma and 1 healthy donor. We sequenced 1,495 cells before, after 1 week, and at clinical relapse to BRAF/MEK inhibitor treatment. We developed an in vitro model of dabrafenib resistance using genetically homogeneous single-cell clones from two cell lines with established BRAF mutations (U266, DP6). Transcriptional and epigenetic adaptation in resistant cells were defined by RNA-seq and H3K27ac chromatin immunoprecipitation sequencing (ChIP-seq). Mitochondrial metabolism was characterized by metabolic flux analysis. RESULTS Profiling by scRNA-seq revealed rapid cellular state changes in response to BRAF/MEK inhibition in patients with myeloma and cell lines. Transcriptional adaptation preceded detectable outgrowth of genetically discernible drug-resistant clones and was associated with widespread enhancer remodeling. As a dominant vulnerability, dependency on oxidative phosphorylation (OxPhos) was induced. In treated individuals, OxPhos was activated at the time of relapse and showed inverse correlation to MAPK activation. Metabolic flux analysis confirmed OxPhos as a preferential energetic resource of drug-persistent myeloma cells. CONCLUSIONS This study demonstrates that cancer cells have the ability to rapidly adapt to precision treatments through transcriptional state changes, epigenetic adaptation, and metabolic rewiring, thus facilitating the development of refractory disease while simultaneously exposing novel vulnerabilities.

Abstract
Abstract
Purpose: Recurrent or metastatic adenoid cystic carcinoma (R/M ACC) is a rare cancer often arising from the salivary glands of the head and neck. While effective therapies are lacking, preclinical models have suggested that retinoic acid agonists may inhibit ACC growth by blocking MYB binding at translocated gene enhancers. We conducted a phase II trial evaluating retinoic acid as a potential novel therapy for R/M ACC. Patients and methods: Patients with histologically confirmed R/M ACC of any primary site with measurable disease (RECIST v1.1), clinical or radiographic progression within 12 months prior to enrollment, and any number of prior lines of therapy were eligible. Cohort 1 (CH1) received ATRA 45 mg/m2 split oral daily dosing on days 1-14 of a 28-day cycle; cohort 2 (CH2) received the same dosing continuously; treatment continued until disease progression. The primary endpoint was best overall response: ≥5 patients in CH1 with disease in response (CR+PR) among N=25 (assuming ≥2 of N=14 accrued in first stage of a two-stage design had disease in response) provided 85% power to target a >10% response rate (one-sided 9% binomial test). Secondary endpoints: safety, progression-free survival (PFS), overall survival. Exploratory analyses: ATRA impact on MYB expression, define resistance mechanisms, and monitor circulating tumor DNA. All had targeted tumor sequencing prior to enrollment. Results: Between 8/2019 and 2/2020, N=14 enrolled in stage 1 CH1. Primary endpoint of response to continue accrual into stage 2 in CH1 was not met; by 5/2020, N=4 enrolled in CH2 when the trial closed to accrual (budget constraints). Among 18 patients, median age: 58, 61% (11/18) women; each patient had a median of 3 organs (range, 1-4) with metastatic disease. 39% had 2+ prior lines of therapy. Best overall response: CR+PR 0%; SD 61% (11/18); PD 28% (5/18); unevaluable 11% (2/18). Median duration of stability 3.5 months (range, 1-12.3+). One patient (CH1) remains on drug with SD >1 year. Half of those who received prior VEGFR therapy achieved SD (4/8). At a median follow-up of 7.9 months, median PFS was 3.2 months (95% CI, 1.8-3.9). N=1 required dose adjustment; N=1 came off drug for toxicity. There were no grade 3-4 adverse events (headache, dry skin were common); no deaths due to treatment. Median tumor mutational burden was 0 (range, 0-5). NOTCH1 was the most frequent alteration (4, 22%) with 2 evaluable NOTCH1-mutant patients exhibiting SD. Mutations in the PI3K pathway, TP53, and TERT promoter were common. Low MYB protein expression was associated with longer duration of stability (p<0.01). Conclusion: While the trial did not meet its prespecified overall response endpoint, SD was observed among R/M ACC patients with disease progression 12 months prior to enrollment. This combined with limited toxicity makes ATRA a treatment option for long-term growth stabilization alone, or worth exploring in combination with other agents for R/M ACC.

Abstract
BACKGROUND Effective therapies are lacking for recurrent, metastatic adenoid cystic carcinoma (R/M ACC) and preclinical models suggest retinoic acid agonists inhibit ACC growth. This phase II trial evaluated all-trans retinoic acid (ATRA) as a novel therapy for ACC. METHODS Patients with R/M ACC (any site) with clinical and/or radiographic progression ≤12 months prior to study entry were eligible. Cohort 1 (CH1) received ATRA 45 mg/m2 split oral daily dosing on days 1-14 of a 28-day cycle; Cohort 2 (CH2) received the same dosing continuously. Primary endpoint was best overall response rate (CR + PR) (RECIST v1.1). Secondary endpoints: safety and progression-free survival (PFS). Exploratory analyses: ATRA impact on MYB expression and genomic predictors of response. RESULTS Eighteen patients enrolled. There were no responses, but 61% (11/18) had stable disease (SD) and 28% (5/18) progression as best response; 11% (2/18) unevaluable. Median duration of stability: 3.7 months (95%CI, 1.9-3.9). One patient (CH1) remains on drug with SD approaching 1 year. Half of those who received prior VEGFR therapy achieved SD (4/8). At median follow up of 7.9 months, median PFS was 3.2 months (95%CI, 1.8-3.9). N = 1 required dose adjustment; N = 1 came off drug for toxicity. There were no grade 3-4 adverse events. NOTCH1 and PI3K pathway alterations were most frequent. Low MYB protein expression was associated with longer duration of stability on ATRA (P < 0.01). CONCLUSION(S) While the trial did not meet its prespecified response endpoint, ATRA alone or in combination may be a low toxicity treatment for disease growth stabilization in R/M ACC.

Abstract
Over the past years, the emergence of liquid biopsy technologies has dramatically expanded our ability to assess multiple myeloma without the need for invasive sampling. Interrogation of cell-free DNA from the peripheral blood recapitulates the mutational landscape at excellent concordance with matching bone marrow aspirates. It can quantify disease burden and identify previously undetected resistance mechanisms which may inform clinical management in real-time. The convenience of sample acquisition and storage provides strong procedural benefits over currently available testing. Further investigations will have to define the role of cell-free DNA as a diagnostic measure by determining clinically relevant tumor thresholds in comparison to existing routine parameters. This review presents an overview of currently available assays and discusses the clinical value, potential and limitations of cell-free DNA technologies for the assessment of this challenging disease.

Abstract
Alzheimer's disease (AD) is the leading neurodegenerative disorder with extracellular senile plaques and neurofibrillary tangles as the major hallmarks. The objective was to evaluate the effect of phloretin in a chronic model of sporadic AD by injecting aggregated form of Aβ25-35 peptide sequence intracerebroventricularly (icv) in Wistar rats. To achieve this, male Wistar rats were injected with aggregated Aβ25-35 peptide icv, followed by 21 days phloretin (2.5 mg/kg, 5 mg/kg) administration after recovery period. Barnes maze and elevated plus maze along with the biochemical estimation of antioxidant enzymes activities were conducted. The hippocampus region of the rat brains were stained with Congo red and Nissl stain. TNF-α was estimated in the brain homogenates using the ELISA assay. In this study, phloretin improved the spatial memory formation and retention in Barnes maze test. Additionally, phloretin alleviated the antioxidant defense biomarkers and thereby reduced oxidative stress, decreased TNF-α-mediated neuroinflammation. Furthermore, phloretin treatment showed decreased amyloid beta accumulation in the CA1 region and less number of pyknotic nuclei in the dentate gyrus of the Aβ25-35-injected rat brains. The above experimental findings evinced the promising role of phloretin in Aβ25-35-injected rats and which further envisage its potential to be explored in the treatment of AD.

Abstract
Background & objectives: Bisphenol A (BPA) is an endocrine disruptor that is widely used in the manufacture of polycarbonate plastics, epoxy resins and dental sealants. It is known to have adverse effects on spermatogenesis in rodents. This study was aimed to evaluate the effects of BPA in adult common marmoset owing to its similarities with human spermatogenesis. Methods: Sixteen marmosets were divided into four groups (n=4 per group) and given oral doses of BPA (2.5, 12.5 and 25 μg/kg BW/day) for 70 days to cover two spermatogenic cycles, and the control group received only vehicle (honey). Testes were processed for histological and transmission electron microscopy studies. Results: Histology of the testis showed sloughing of germ cells into the lumen, increase in interstitial space and vacuolation of Sertoli cell cytoplasm. Ultrastructural analysis of the testis revealed several degenerative effects on the basement membrane, Sertoli cells, Leydig cells and other developing germ cells in the 12.5 and 25 μg/kg BW/day groups as compared to control. Interpretation & conclusions: The observed ultrastructural changes caused by BPA in testicular morphology might be indicative of a perturbed sperm production. Considering the genetic and spermatogenic similarities of common marmoset (Callithrix jacchus) and humans, the study findings are of significance. Further studies are, however, needed to elucidate the mechanism of action.

Abstract
Cruciferous vegetables such as broccoli and kale have well documented chemopreventative and anticancer effects that are attributed to the presence of isothiocyanates (ITCs). ITCs modulate the levels of many oncogenic proteins, but the molecular mechanisms of ITC action are not understood. We previously reported that phenethyl isothiocyanate (PEITC) inhibits two deubiquitinases (DUBs), USP9x and UCH37. DUBs regulate many cellular processes and DUB dysregulation is linked to the pathogenesis of human diseases including cancer, neurodegeneration, and inflammation. Using SILAC assisted quantitative mass spectrometry, here we identify 9 new PEITC-DUB targets: USP1, USP3, USP10, USP11, USP16, USP22, USP40, USP48 and VCPIP1. Seven of these PEITC-sensitive DUBs have well-recognized roles in DNA repair or chromatin remodeling. PEITC both inhibits USP1 and increases its ubiquitination and degradation, thus decreasing USP1 activity by two mechanisms. The loss of USP1 activity increases the level of mono-ubiquitinated DNA clamp PCNA, impairing DNA repair. Both the inhibition/degradation of USP1 and the increase in mono-ubiquitinated PCNA are new activities for PEITC that can explain the previously recognized ability of ITCs to enhance cancer cell sensitivity to cisplatin treatment. Our work also demonstrates that PEITC reduces the mono-ubiquityl histones H2A and H2B. Understanding the mechanism of action of ITCs should facilitate their use as therapeutic agents.

Abstract
Background: Reverse pharmacology for drug development has been highly productive and cost-effective in recent past as it is based on the documented therapeutic effects of plants in ancient texts. Afrodet Plus® is formulated for the treatment of male infertility, which contains ancient herbo-minerals. Its efficacy and safety are validated through this animal study in reverse pharmacology mode. Objectives: This study was undertaken to evaluate efficacy and safety of an Ayurvedic formulation Afrodet Plus® in adult male rats. Materials and Methods: Twelve male rats (Holtzman) between 8 and 10 weeks of age were randomly selected and animals were assigned to a control and two treatment groups. Dosing was performed daily. Various parameters such as weekly body weight, hematology, serum testosterone levels, epididymal sperm count, and efficiency of Daily Sperm Production (DSP) were evaluated. Results: It was found that epididymal sperm count had significantly increased in both low-dose (+27.39%) and high-dose (+40.5%) groups as compared to control group. The DSP also showed an increase of 43.7% at high dose of 180 mg/kg body weight as compared to the control group. An increase in sperm motility and especially progressive motility was observed when evaluated by Computer Assisted Semen Analyzer. Histological evaluation of testicular tissue for spermatogenic index revealed that the index had increased in treatment group as compared to control group. Conclusion: This study revealed that oral administration of Afrodet Plus® resulted in significant increase in DSP in the testis along with increase in epididymal sperm count and progressive motility as compared to control group without producing any treatment-related adverse effects. These findings provide the documentary evidence that the use of Afrodet Plus® at 90 and 180 mg/kg body weight is effective and safe for the treatment of male infertility especially to improve sperm count and progressive motility.

Abstract
Electron beam induced carbonaceous deposition has been carried out in the presence of water vapor at 0.4 torr pressure amidst residual hydrocarbons present in the SEM chamber. When performed at a CNT location on a Si substrate with low e beam energy (10 kV), the deposition was taking place beneath the CNT. While higher beam energy (25 kV) causing the deposition on the top surface of the CNT, in agreement with the earlier reports. The insertion of dielectric carbonaceous layer beneath the CNT allowed us to measure the I-V data along the length of the nanotube using CAFM.

Abstract
Nanopatterning of Si(100) surfaces deposited with Au films from physical and chemical methods, has been carried out using a AFM set up mounted with a conducting tip. At a tip bias of -12 V, the LAO patterns drawn on various Au/SiOx surfaces have been compared with those on bare Si. The height of the oxide patterns is several times higher in the case of Au covered Si surfaces compared to patterns on bare Si surface. The enhancement in LAO is related to the catalytic activity of Au nanoparticulates at SiOx interface.

Abstract
Thyroid abscess arising from Acute Suppurative Thyroiditis (AST) is a rare clinical disorder. The ability of the thyroid gland to resist infection is well known and infection in the thyroid gland is rare, particularly so with the advent of widespread usage of antibiotics. An internal pharyngeal fistula (Pyriform sinus fistula) is the most common underlying abnormality in patients with AST. We report a case of an adult male who presented with a thyroid abscess. The causal organism was found to be Staphylococcus aureus. Intravenous antibiotics and, incision and drainage of the abscess led to an uncomplicated recovery.

Abstract
Cell-mediated and humoral immune responses were assessed in forty patients with chronic generalized periodontitis (CGP), and in an equal number of control subjects. The cell mediated immunity assessed by enumeration of total rosette forming cells [TRFC] and high affinity rosette forming cells [HARFC], were found to be slightly depressed in CGP patients compared controls. The humoral immune response was assessed by estimation of serum immunoglobulins G,A,M,D and E by single radial immunodiffusion technique (RID). Except IgD all the other immunoglobulins were found to be elevated significantly. These immunological derangements found in CGP patients may be the cause or effect of the disease process.
