Abstract
OBJECTIVE Genomic studies of gastric cancer have identified highly recurrent genomic alterations impacting RHO signalling, especially in the diffuse gastric cancer (DGC) histological subtype. Among these alterations are interchromosomal translations leading to the fusion of the adhesion protein CLDN18 and RHO regulator ARHGAP26. It remains unclear how these fusion constructs impact the activity of the RHO pathway and what is their broader impact on gastric cancer development. Herein, we developed a model to allow us to study the function of this fusion protein in the pathogenesis of DGC and to identify potential therapeutic targets for DGC tumours with these alterations. DESIGN We built a transgenic mouse model with LSL-CLDN18-ARHGAP26 fusion engineered into the Col1A1 locus where its expression can be induced by Cre recombinase. Using organoids generated from this model, we evaluated its oncogenic activity and the biochemical effects of the fusion protein on the RHOA pathway and its downstream cell biological effects in the pathogenesis of DGC. RESULTS We demonstrated that induction of CLDN18-ARHGAP26 expression in gastric organoids induced the formation of signet ring cells, characteristic features of DGC and was able to cooperatively transform gastric cells when combined with the loss of the tumour suppressor geneTrp53. CLDN18-ARHGAP26 promotes the activation of RHOA and downstream effector signalling. Molecularly, the fusion promotes activation of the focal adhesion kinase (FAK) and induction of the YAP pathway. A combination of FAK and YAP/TEAD inhibition can significantly block tumour growth. CONCLUSION These results indicate that the CLDN18-ARHGAP26 fusion is a gain-of-function DGC oncogene that leads to activation of RHOA and activation of FAK and YAP signalling. These results argue for further evaluation of emerging FAK and YAP-TEAD inhibitors for these deadly cancers.

Abstract
During tumor development, promoter CpG islands (CGIs) that are normally silenced by Polycomb repressive complexes (PRCs) become DNA hypermethylated. The molecular mechanism by which de novo DNA methyltransferase(s) catalyze CpG methylation at PRC-regulated regions remains unclear. Here we report a cryo-EM structure of the DNMT3A long isoform (DNMT3A1) N-terminal region in complex with a nucleosome carrying PRC1-mediated histone H2A lysine 119 monoubiquitination (H2AK119Ub). We identify regions within the DNMT3A1 N-terminus that bind H2AK119Ub and the nucleosome acidic patch. This bidentate interaction is required for effective DNMT3A1 engagement with H2AK119Ub-modified chromatin in cells. Furthermore, aberrant redistribution of DNMT3A1 to Polycomb target genes inhibits their transcriptional activation during cell differentiation and recapitulates the cancer-associated DNA hypermethylation signature. This effect is rescued by disruption of the DNMT3A1-acidic patch interaction. Together, our analyses reveal a binding interface critical for countering promoter CGI DNA hypermethylation, a major molecular hallmark of cancer.

Abstract
Interplay between chromatin-associated complexes and modifications critically contribute to the partitioning of epigenome into stable and functionally distinct domains. Yet there is a lack of systematic identification of chromatin crosstalk mechanisms, limiting our understanding of the dynamic transition between chromatin states during development and disease. Here we perform co-dependency mapping of genes using CRISPR-Cas9-mediated fitness screens in pan-cancer cell lines to quantify gene-gene functional relationships. We identify 145 co-dependency modules and further define the molecular context underlying the essentiality of these modules by incorporating mutational, epigenome, gene expression and drug sensitivity profiles of cell lines. These analyses assign new protein complex composition and function, and predict new functional interactions, including an unexpected co-dependency between two transcriptionally counteracting chromatin complexes - polycomb repressive complex 2 (PRC2) and MLL-MEN1 complex. We show that PRC2-mediated H3K27 tri-methylation regulates the genome-wide distribution of MLL1 and MEN1. In lymphoma cells with EZH2 gain-of-function mutations, the re-localization of MLL-MEN1 complex drives oncogenic gene expression and results in a hypersensitivity to pharmacologic inhibition of MEN1. Together, our findings provide a resource for discovery of trans-regulatory interactions as mechanisms of chromatin regulation and potential targets of synthetic lethality.

Abstract
Cancer-associated fibroblasts (CAF) can promote tumor growth, metastasis, and therapeutic resistance in esophageal squamous cell carcinoma (ESCC), but the mechanisms of action remain elusive. Our objective was to identify secreted factor(s) that mediate the communication between CAFs and ESCC tumor cells with the aim of identifying potential druggable targets. Through unbiased cytokine arrays, we have identified CC motif chemokine ligand 5 (CCL5) as a secreted factor that is increased upon co-culture of ESCC cells and CAFs, which we replicated in esophageal adenocarcinoma (EAC) with CAFs. Loss of tumor-cell-derived CCL5 reduces ESCC cell proliferation in vitro and in vivo and we propose this is mediated, in part, by a reduction in ERK1/2 signaling. Loss of tumor-derived CCL5 reduces the percentage of CAFs recruited to xenograft tumors in vivo. CCL5 is a ligand for the CC motif receptor 5 (CCR5), for which a clinically approved inhibitor exists, namely Maraviroc. Maraviroc treatment reduced tumor volume, CAF recruitment, and ERK1/2 signaling in vivo, thus, mimicking the effects observed with genetic loss of CCL5. High CCL5 or CCR5 expression is associated with worse prognosis in low-grade esophageal carcinomas. IMPLICATIONS These data highlight the role of CCL5 in tumorigenesis and the therapeutic potential of targeting the CCL5-CCR5 axis in ESCC.

Abstract
Therapy with radiation plus cisplatin kills HPV+ oropharyngeal squamous cell carcinomas (OPSCCs) by increasing reactive oxygen species beyond cellular antioxidant capacity. To explore why these standard treatments fail for some patients, we evaluated whether the variation in HPV oncoprotein levels among HPV+ OPSCCs affects mitochondrial metabolism, a source of antioxidant capacity. In cell line and patient-derived xenograft models, levels of HPV full-length E6 (fl-E6) inversely correlated with oxidative phosphorylation, antioxidant capacity, and therapy resistance, and fl-E6 was the only HPV oncoprotein to display such correlations. Ectopically expressing fl-E6 in models with low baseline levels reduced mitochondrial mass, depleted antioxidant capacity, and sensitized to therapy. In this setting, fl-E6 repressed the peroxisome proliferator-activated receptor gamma co-activator 1α/estrogen-related receptor α (PGC-1α/ERRα) pathway for mitochondrial biogenesis by reducing p53-dependent PGC-1α transcription. Concordant observations were made in 3 clinical cohorts, where expression of mitochondrial components was higher in tumors of patients with reduced survival. These tumors contained the lowest fl-E6 levels, the highest p53 target gene expression, and an activated PGC-1α/ERRα pathway. Our findings demonstrate that E6 can potentiate treatment responses by depleting mitochondrial antioxidant capacity and provide evidence for low E6 negatively affecting patient survival. E6's interaction with the PGC-1α/ERRα axis has implications for predicting and targeting treatment resistance in OPSCC.

Abstract
Melanoma brain metastasis (MBM) frequently occurs in patients with advanced melanoma; yet, our understanding of the underlying salient biology is rudimentary. Here, we performed single-cell/nucleus RNA-seq in 22 treatment-naive MBMs and 10 extracranial melanoma metastases (ECMs) and matched spatial single-cell transcriptomics and T cell receptor (TCR)-seq. Cancer cells from MBM were more chromosomally unstable, adopted a neuronal-like cell state, and enriched for spatially variably expressed metabolic pathways. Key observations were validated in independent patient cohorts, patient-derived MBM/ECM xenograft models, RNA/ATAC-seq, proteomics, and multiplexed imaging. Integrated spatial analyses revealed distinct geography of putative cancer immune evasion and evidence for more abundant intra-tumoral B to plasma cell differentiation in lymphoid aggregates in MBM. MBM harbored larger fractions of monocyte-derived macrophages and dysfunctional TOX+CD8+ T cells with distinct expression of immune checkpoints. This work provides comprehensive insights into MBM biology and serves as a foundational resource for further discovery and therapeutic exploration.

Abstract
Abstract
BACKGROUND: Elevated mitochondrial antioxidant defenses contribute to progression and therapy resistance of some poor prognosis cancer types. By contrast, HPV+ oropharyngeal squamous cell carcinomas (OPSCCs) are generally sensitive to oxidative damage from radiation plus cisplatin, which are often curative. It is unknown whether the subset of HPV+ OPSCCs with poor outcomes exploit antioxidant capacity provided by high mitochondrial mass to evade therapy. It is also unclear whether the wide range of HPV oncoprotein expression among them contributes to diversity in mitochondrial mass and treatment outcomes.
AIMS: (1) evaluate HPV+ OPSCCs for associations between mitochondrial mass and clinical outcome (2) elucidate relationships among HPV oncoprotein levels, mitochondrial mass, and therapy response (3) delineate mechanisms by which variable HPV oncoprotein levels govern therapy response.
METHODS/RESULTS: High expression of genes involved in oxidative metabolism was associated with decreased survival in three patient cohorts. In PDX and cell line models, cisplatin resistance positively correlated with mitochondrial mass (MTCO1/B2M), oxidative metabolism (basal OCR), and antioxidant capacity (NADPH/NADP+). Among the HPV oncoproteins, only full length E6 (fl-E6) was linked to these features, showing negative correlation with mitochondrial mass in the cell lines, PDXs, and patient tumors. Fl-E6 levels also positively correlated with cisplatin response in the PDXs and cell lines. To test whether fl-E6 can mediate such effects, lentiviral fl-E6 expression in HPV+ cancer cell lines with low endogenous fl-E6 was used to increase levels to the high end of the range seen in human tumors. Doing so reduced MTCO1/B2M, basal OCR, and NADPH/NADP+ while sensitizing to radiation and cisplatin in vitro and in vivo. The same effects on mitochondrial biogenesis were maintained in nTERT/E7 keratinocytes. Using luciferase reporter assays, fl-E6 was shown to repress the PGC-1/ERR axis for mitochondrial biogenesis by attenuating p53-dependent PGC1α promoter activity. The prediction of PGC1/ERR axis activation in tumors with low fl-E6 was confirmed in PDXs and patient cohorts, where high ERRα was negatively prognostic.
CONCLUSIONS: These results reveal a novel ability of E6-mediated p53 downregulation to contribute to treatment sensitivity by depleting mitochondrial antioxidant capacity. They also provide evidence that differing fl-E6 levels across HPV+ cancers variably repress the PGC1/ERR pathway, leading to diversity in mitochondrial mass that impacts therapy response. Therapy-refractory features may prove identifiable using expression-based biomarkers in the PGC1/ERR axis and be mitigated through targetable nodes in this pathway. In addition, HPV+ OPSCCs may find competitive advantage in down-regulating fl-E6 upon acquiring alternate drivers to compensate decrease in its oncogenic functions.

Abstract
Chromatin dysfunction has been implicated in a growing number of cancers especially in children and young adults. In addition to chromatin modifying and remodeling enzymes, mutations in histone genes are linked to human cancers. Since the first reports of hotspot missense mutations affecting key residues at histone H3 tail, studies have revealed how these so-called "oncohistones" dominantly (H3K27M and H3K36M) or locally (H3.3G34R/W) inhibit corresponding histone methyltransferases and misregulate epigenome and transcriptome to promote tumorigenesis. More recently, widespread mutations in all four core histones are identified in diverse cancer types. Furthermore, an "oncohistone-like" protein EZHIP has been implicated in driving childhood ependymomas through a mechanism highly reminiscent of H3K27M mutation. We will review recent progresses on understanding the biochemical, molecular and biological mechanisms underlying the canonical and novel histone mutations. Importantly, these mechanistic insights have identified therapeutic opportunities for oncohistone-driven tumors.

Abstract
Esophageal cancers comprise adenocarcinoma and squamous cell carcinoma, two distinct histologic subtypes. Both are difficult to treat and among the deadliest human malignancies. We describe protocols to initiate, grow, passage, and characterize patient-derived organoids (PDO) of esophageal cancers, as well as squamous cell carcinomas of oral/head-and-neck and anal origin. Formed rapidly (<14 days) from a single-cell suspension embedded in basement membrane matrix, esophageal cancer PDO recapitulate the histology of the original tumors. Additionally, we provide guidelines for morphological analyses and drug testing coupled with functional assessment of cell response to conventional chemotherapeutics and other pharmacological agents in concert with emerging automated imaging platforms. Predicting drug sensitivity and potential therapy resistance mechanisms in a moderate-to-high throughput manner, esophageal cancer PDO are highly translatable in personalized medicine for customized esophageal cancer treatments. © 2020 by John Wiley & Sons, Inc.

Abstract
Pancreatic cancer metastasis is a leading cause of cancer-related deaths, yet very little is understood regarding the underlying biology. As a result, targeted therapies to inhibit metastasis are lacking. Here, we report that the parathyroid hormone-related protein (PTHrP encoded by PTHLH) is frequently amplified as part of the KRAS amplicon in patients with pancreatic cancer. PTHrP upregulation drives the growth of both primary and metastatic tumors in mice and is highly enriched in pancreatic ductal adenocarcinoma metastases. Loss of PTHrP-either genetically or pharmacologically-dramatically reduces tumor burden, eliminates metastasis, and enhances overall survival. These effects are mediated in part through a reduction in epithelial-to-mesenchymal transition, which reduces the ability of tumor cells to initiate metastatic cascade. Spp1, which encodes osteopontin, is revealed to be a downstream effector of PTHrP. Our results establish a new paradigm in pancreatic cancer whereby PTHrP is a driver of disease progression and emerges as a novel therapeutic vulnerability. SIGNIFICANCE: Pancreatic cancer often presents with metastases, yet no strategies exist to pharmacologically inhibit this process. Herein, we establish the oncogenic and prometastatic roles of PTHLH, a novel amplified gene in pancreatic ductal adenocarcinoma. We demonstrate that blocking PTHrP activity reduces primary tumor growth, prevents metastasis, and prolongs survival in mice.This article is highlighted in the In This Issue feature, p. 1601.

Abstract
Abstract
Introduction: Heavy alcohol (EtOH) drinking and tobacco smoking increase the risk for upper digestive (e.g. oral and esophageal) squamous cell carcinomas (SCC) in individuals with polymorphic mutations in aldehyde dehydrogenase 2 (Aldh2). Mutant Aldh2E487K protein delays mitochondrial clearance of acetaldehyde, the chief metabolite of EtOH and constituents of tobacco smoke, aka a major human carcinogen. The role of Aldh2 in tumor biology remains elusive.
Methods: Single cell-derived three-dimensional (3D) organoids were generated from murine oral and esophageal preneoplastic and SCC lesions carrying wild-type Aldh2WT or mutant Aldh2E487K as well as human SCC cell lines with Aldh2E487K, the latter subjected to xenograft transplantation in immunodeficient mice. 3D organoids and xenograft tumors were analyzed by morphology and flow cytometry to determine CD44, autophagy (cyto-ID), proliferation (EdU), and reactive oxygen species (ROS) following EtOH exposure ex vivo (0.1-2% EtOH) or in vivo (10% EtOH in drinking water) along with or without inhibitors of alcohol metabolism (4-methylpyrazole; 4MP, siRNA against Adh1B and Cyp2E1), and autophagy flux (chloroquine; CQ or siRNA against Atg7). Flow cytometry was performed to determine cancer stem-like cells with high CD44 expression (CD44H cells).
Results: EtOH stimulated xenograft tumor growth and increased highly proliferative intratumoral CD44H cells with increased autophagy. EtOH-stimulated tumor growth and induction of CD44H cells were sharply suppressed by concurrent 4MP treatment, indicating that EtOH is directly metabolized in SCC cells to promote tumor growth via CD44H cells. These EtOH-induced effects were recapitulated in 3D organoids where Aldh2E487K augmented EtOH-mediated induction of CD44H cells and organoid formation with increased cellular atypia. EtOH induced mitochondrial superoxide and ROS-dependent autophagy activation in CD44H cells. Inhibition of autophagy prevented EtOH from enriching CD44H cells in 3D organoids, suggesting that autophagy may limit alcohol-induced oxidative stress as a cytoprotective mechanism.
Conclusions: These studies provide not only mechanistic insights into the role of Aldh2 mutation in oral and esophageal SCC pathogenesis but also establish the utility of the 3D organoid system to test the functional interplay between genetic and environmental factors which may subsequently be targeted for pharmacological intervention in the setting of personalized medicine.

Abstract
Therapeutic innovation for human papilloma virus-related (HPV+) head and neck squamous cell carcinomas (HNSCCs) is impaired by inadequate preclinical models and the absence of accurate biomarkers. Our study establishes the first well-characterized panel of patient-derived xenografts (PDXs) and organoids from HPV+ HNSCCs while determining fidelity of the models to the distinguishing genetic features of this cancer type. Despite low engraftment rates, whole exome sequencing showed that PDXs retain multiple distinguishing features of HPV+ HNSCC lost in existing cell lines, including PIK3CA mutations, TRAF3 deletion and the absence of EGFR amplifications. Engrafted HPV+ tumors frequently contained NOTCH1 mutations, thus providing new models for a negatively prognostic alteration in this disease. Genotype-phenotype associations in the models were then tested for prediction of tumor progression and survival in published clinical cohorts. Observation of high tumor mutational burdens (TMBs) in the faster-growing models facilitated identification of a novel association between TMB and local progression in both HPV+ and HPV- patients that was prognostic in HPV- cases. In addition, reduced E7 and p16INK4A levels found in a PDX from an outlier case with lethal outcome led to detection of similar profiles among recurrent HPV+ HNSCCs. Transcriptional data from the Cancer Genome Atlas was used to demonstrate that the lower E2F target gene expression predicted by reduced E7 levels has potential as a biomarker of disease recurrence risk. Our findings bridge a critical gap in preclinical models for HPV+ HNSCCs and simultaneously reveal novel potential applications of quantifying mutational burden and viral oncogene functions for biomarker development.

Abstract
6057 Background: Advancing therapy for human papilloma virus-related (HPV+) head and neck squamous cell carcinoma (HNSCC) is hindered by inadequate preclinical models and risk stratification tools. This study addresses both barriers by characterizing a panel of patient-derived xenografts (PDXs) that includes nine new models of HPV+ disease. Methods: Exome-sequenced genetic features of the PDXs were compared to their growth properties and the outcomes of their patients of origin. Genetic traits with potential prognostic utility were validated in multiple retrospective patient cohorts. Results: The HPV+ PDXs avoided known artifacts in HPV+ cell lines, including 3q amplifications and loss of PIK3CA mutants, while enriching for alterations in H3K4 methyltransferases and Notch pathway genes. A positive association emerged between PDX tumor mutational burden (TMB) and their growth efficiency both in vivo and as organoids. This finding led to identification in The Cancer Genome Atlas (TCGA) of an association between high TMB and worse survival of early-stage HPV-negative cancers but not HPV+ ones. Insight into aggressive HPV+ disease came from a PDX established from a patient before lethal relapse. The reduced levels of viral E7 and p16INK4A present in this model were also detected in early lethal HPV+ cases in TCGA as well as the recurrences in a second HPV+ HNSCC cohort (JHU). This observation suggested a diminished contribution of viral oncogenes to cell cycle dysregulation in aggressive cases. To evaluate this possibility, hierarchical clustering of both cohorts was performed based on expression of E2F target genes. This analysis discovered a distinct cell cycle-related transcriptional pattern in the clusters of cases containing the recurrences and early lethal events. Furthermore, a subset of these transcripts proved to be stage-independent predictors of survival for the HPV+ HNSCCs in both TCGA and JHU cohorts. Conclusions: Characterizing the most HPV+ patient-derived models described to date revealed novel prognostic utility for E2F target expression in HPV+ HNSCCs and TMB in HPV-negative HNSCCs. These features have potential for application to risk stratification, biomarker development, and trial design.

Abstract
BACKGROUND & AIMS Oropharyngeal and esophageal squamous cell carcinomas, especially the latter, are a lethal disease, featuring intratumoral cancer cell heterogeneity and therapy resistance. To facilitate cancer therapy in personalized medicine, three-dimensional (3D) organoids may be useful for functional characterization of cancer cells ex vivo. We investigated the feasibility and the utility of patient-derived 3D organoids of esophageal and oropharyngeal squamous cell carcinomas. METHODS We generated 3D organoids from paired biopsies representing tumors and adjacent normal mucosa from therapy-naïve patients and cell lines. We evaluated growth and structures of 3D organoids treated with 5-fluorouracil ex vivo. RESULTS Tumor-derived 3D organoids were grown successfully from 15 out of 21 patients (71.4%) and passaged with recapitulation of the histopathology of the original tumors. Successful formation of tumor-derived 3D organoids was associated significantly with poor response to presurgical neoadjuvant chemotherapy or chemoradiation therapy in informative patients (P = 0.0357, progressive and stable diseases, n = 10 vs. partial response, n = 6). The 3D organoid formation capability and 5-fluorouracil resistance were accounted for by cancer cells with high CD44 expression and autophagy, respectively. Such cancer cells were found to be enriched in patient-derived 3D organoids surviving 5-fluorouracil treatment. CONCLUSIONS The single cell-based 3D organoid system may serve as a highly efficient platform to explore cancer therapeutics and therapy resistance mechanisms in conjunction with morphological and functional assays with implications for translation in personalized medicine.

Abstract
The tumor microenvironment (TME) plays a major role in the pathogenesis of multiple cancer types, including upper-gastrointestinal (GI) cancers that currently lack effective therapeutic options. Cancer-associated fibroblasts (CAF) are an essential component of the TME, contributing to tumorigenesis by secreting growth factors, modifying the extracellular matrix, supporting angiogenesis, and suppressing antitumor immune responses. Through an unbiased approach, we have established that IL-6 mediates cross-talk between tumor cells and CAF not only by supporting tumor cell growth, but also by promoting fibroblast activation. As a result, IL-6 receptor (IL6Rα) and downstream effectors offer opportunities for targeted therapy in upper-GI cancers. IL-6 loss suppressed tumorigenesis in physiologically relevant three-dimensional (3D) organotypic and 3D tumoroid models and murine models of esophageal cancer. Tocilizumab, an anti-IL6Rα antibody, suppressed tumor growth in vivo in part via inhibition of STAT3 and MEK/ERK signaling. Analysis of a pan-cancer TCGA dataset revealed an inverse correlation between IL-6 and IL6Rα overexpression and patient survival. Therefore, we expanded evaluation of tocilizumab to head and neck squamous cell carcinoma patient-derived xenografts and gastric adenocarcinoma xenografts, demonstrating suppression of tumor growth and altered STAT3 and ERK1/2 gene signatures. We used small-molecule inhibitors of STAT3 and MEK1/2 signaling to suppress tumorigenesis in the 3D organotypic model of esophageal cancer. We demonstrate that IL6 is a major contributor to the dynamic cross-talk between tumor cells and CAF in the TME. Our findings provide a translational rationale for inhibition of IL6Rα and downstream signaling pathways as a novel targeted therapy in oral-upper-GI cancers.Significance: These findings demonstrate the interaction of esophageal cancer and cancer-associated fibroblasts through IL-6 signaling, providing rationale for a novel therapeutic approach to target these cancers.

Abstract
Upregulation of the H3K4me3 demethylase JARID1B is linked to acquisition of aggressive, stem cell-like features by many cancer types. However, the utility of emerging JARID1 family inhibitors remains uncertain, in part because JARID1B’s functions in normal development and malignancy are diverse and highly context-specific. In this study, responses of oral squamous cell carcinomas (OSCCs) to catalytic inhibition of JARID1B were assessed using CPI-455, the first tool compound with true JARID1 family selectivity. CPI-455 attenuated clonal sphere and tumor formation by stem-like cells that highly express JARID1B while also depleting the CD44-positive and Aldefluor-high fractions conventionally used to designate OSCC stem cells. Silencing JARID1B abrogated CPI-455’s effects on sphere formation, supporting that the drug acted through this isoform. To further delineate CPI-455’s capacity to block JARID1B’s functions, its biologic effects were compared against those indicated by pathway analysis of the transcriptional profile produced by JARID1B knockdown. Downregulation of multiple gene sets related to stem cell function was consistent with the drug’s observed actions. However, strong E-Cadherin upregulation seen upon silencing JARID1B surprisingly could not be reproduced using CPI-455. Expressing a demethylase-inactive mutant of JARID1B demonstrated suppression of this transcript to be demethylase-independent, and the capacity of mutant JARID1B but not CPI-455 to modulate invasion provided a functional correlate of this finding. These results show that JARID1B catalytic inhibition effectively targets some stem cell-like features of malignancy but also reveal demethylase-independent actions refractory to inhibition. Future application of JARID1 inhibitors in combinatorial use for cancer therapy may be guided by these findings.

Abstract
Notch1 transactivates Notch3 to drive terminal differentiation in stratified squamous epithelia. Notch1 and other Notch receptor paralogs cooperate to act as a tumor suppressor in squamous cell carcinomas (SCCs). However, Notch1 can be stochastically activated to promote carcinogenesis in murine models of SCC. Activated form of Notch1 promotes xenograft tumor growth when expressed ectopically. Here, we demonstrate that Notch1 activation and epithelial–mesenchymal transition (EMT) are coupled to promote SCC tumor initiation in concert with transforming growth factor (TGF)-β present in the tumor microenvironment. We find that TGFβ activates the transcription factor ZEB1 to repress Notch3, thereby limiting terminal differentiation. Concurrently, TGFβ drives Notch1-mediated EMT to generate tumor initiating cells characterized by high CD44 expression. Moreover, Notch1 is activated in a small subset of SCC cells at the invasive tumor front and predicts for poor prognosis of esophageal SCC, shedding light upon the tumor promoting oncogenic aspect of Notch1 in SCC. Notch receptors can exert different roles in cancer. In this manuscript, the authors reveal that Notch1 activation and EMT promote tumor initiation and cancer cell heterogeneity in squamous cell carcinoma, while the repression of Notch3 by ZEB1 limits Notch1-induced differentiation, permitting Notch1-mediated EMT.

Abstract
OBJECTIVES/HYPOTHESIS Delineate factors impacting the creation and use of patient-derived xenografts (PDXs) of human papilloma virus-related (HPV+) head and neck squamous cell carcinomas (HNSCCs). STUDY DESIGN Laboratory-based translational study. METHODS Fifty-one surgically resected HNSCCs, including 31 HPV + cancers, were implanted into NOD/SCID/IL-2Rγ-/- (NSG) mice using standardized methodology. Clinical and pathologic factors were tested for association with engraftment. The gross, histologic, and molecular features of established HPV + PDXs were analyzed in comparison to their tumors of origin. RESULTS Negative HPV status and perineural invasion (PNI) were independent, additive factors associated with increased PDX formation. Epstein-Barr virus-positive (EBV+) human large B-cell lymphomas grew from 32% of HPV + HNSCC cases that failed to engraft. Successfully established HPV + PDXs retained basaloid histology and often developed cystic growth patterns typical of HPV + nodal metastases. They also maintained elevated p16INK4A levels and expression of E6/E7 viral oncogene transcripts. CONCLUSION Reduced engraftment by HPV + tumors lacking PNI likely results in selection biases in HNSCC PDX models. Formation of EBV + lymphomas in NSG mice further reduces the generation of HPV + models and must be ruled out before long-term use of PDXs. Nevertheless, the retention of distinctive pathologic traits and viral oncogene expression by HPV + PDXs provides a viable in vivo platform for basic and translational studies as well as a resource for generating advanced in vitro models.

Abstract
BACKGROUND Cyclin dependent kinases (CDK) are key factors in promoting the initiation and development of tumors. These kinases are important for maintenance of mitochondrial biogenesis and imbalance in their expression in old age may lead to the oxidative stress. Lung cancer (LC), and head and neck squamous cell carcinoma (HNSCC) are two very prominent cancers in older Indians. Both the cancers are showing increasing trend in older population. The present study assessed serum concentration of one of the kinases; CDK4 in older LC and HNSCC patients. METHODS The study included 100 subjects each of LC and HNSCC; and older subjects without cancer or any major health problems as controls. Serum CDK4 concentration was estimated using real-time label-free Surface plasmon resonance (SPR) and was verified by western blot. RESULTS Significant elevation in serum CDK4 was observed in cases with LC and HNSCC compared to controls. HNSCC patients with higher CDK4 expression had distinctly shorter survival than patients with comparatively lower CDK4 expression. No such difference was observed in LC patients. The germ line mutation study of this gene in Exon-2 was performed and none was observed among cases and controls. CONCLUSION It can be concluded that older patients with HNSCC and lung cancer have raised serums CDK4 levels, which has the potential to emerge as a biomarker in clinical practice.

Abstract
The degree of heterogeneity among cancer stem cells (CSC) remains ill-defined and may hinder effective anti-CSC therapy. Evaluation of oral cancers for such heterogeneity identified two compartments within the CSC pool. One compartment was detected using a reporter for expression of the H3K4me3 demethylase JARID1B to isolate a JARID1B(high) fraction of cells with stem cell-like function. JARID1B(high) cells expressed oral CSC markers including CD44 and ALDH1 and showed increased PI3K pathway activation. They were distinguished from a fraction in a G0-like cell-cycle state characterized by low reactive oxygen species and suppressed PI3K/AKT signaling. G0-like cells lacked conventional CSC markers but were primed to acquire stem cell-like function by upregulating JARID1B, which directly mediated transition to a state expressing known oral CSC markers. The transition was regulated by PI3K signals acting upstream of JARID1B expression, resulting in PI3K inhibition depleting JARID1B(high) cells but expanding the G0-like subset. These findings define a novel developmental relationship between two cell phenotypes that may jointly contribute to CSC maintenance. Expansion of the G0-like subset during targeted depletion of JARID1B(high) cells implicates it as a candidate therapeutic target within the oral CSC pool. Cancer Res; 76(18); 5538-49. ©2016 AACR.
