(Submitter supplied) Pancreatic ductal adenocarcinoma (PDAC) is characterized by the presence of abundant desmoplatic stroma primarily composed of cancer-associated fibroblasts (CAFs). It is generally accepted that CAFs stimulate tumor progression and might be implicated in drug resistance and immunosuppression. Here, we have compared the transcriptional profile of PDGFRα+ CAFs isolated from genetically engineered mouse PDAC tumors with that of normal pancreatic fibroblasts (NPFs) to identify genes potentially implicated in their pro-tumorigenic properties. more...

(Submitter supplied) Pancreatic ductal adenocarcinoma (PDAC) has a characteristically dense stroma comprised predominantly of cancer associated fibroblasts (CAFs). CAFs promote tumor growth, metastasis and treatment resistance. We aimed to investigate the molecular changes and functional consequences associated with chemotherapy treatment of PDAC CAFs. Chemoresistant immortalized CAFs (R-CAFs) were generated by continuous incubation in 100nM gemcitabine. more...

(Submitter supplied) Purpose: The goal of this study was to identify BET-dependent pathways in the PDAC stroma and the epithelial compartment. Methods: Monocultures and Cocultures of a low passage PDAC cell line (MGH1319) and a cancer-associated fibroblast cell line (CAF-1) were treated with either BETi (CPI203) or CTRL for 24 hours. Each condition was done as a single experiment and all cells were subjected to FACS, RNA was isolated using the RNeasy Micro Kit (CAT No.74004) and sequenced at 75 bp Pair End on the NextSeq sequencer (Illumina). more...

(Submitter supplied) Transcriptomic profiling of pancreatic cancer-associated fibroblasts (CAFs) was done to evaluate the expression of GPCRs. The same was also done for normal pancreatic stellate cells, so as to evaluate whether a population of GPCRs shows increased expression in CAFs vs their normal precursors. We report the discovery of a novel GPCR in CAFs; we demonstrate this GPCR helps to drive the cross-talk between CAFs and cancer cells, enhancing the growth of pancreatic cancer cells.

(Submitter supplied) This study used 10X Genomics, single-cell RNA-sequencing to examine the cell types present in the KrasLSL-G12D; Trp53LSL-R172H; Pdx1-Cre (KPC) mouse model for pancreatic ductal adenocarcinoma. The study analyzed tumors from 4 different mice. For each tumor, we performed flow sorting to isolate all viable cells, and to isolate a fibroblast-enriched population of cells for single-cell RNA-seq to determine the transcriptomes of individual cells in KPC pancreatic ductal adenocarcinoma tumors.

(Submitter supplied) Background & Aims: Pancreatic ductal adenocarcinomas (PDAC) are characterized by fibrosis and an abundance of cancer-associated fibroblasts (CAFs). We investigated strategies to disrupt interactions among CAFs, the immune system, and cancer cells, focusing on adhesion molecule cadherin 11 (CDH11), which has been associated with other fibrotic disorders and is expressed by activated fibroblasts. Methods: We compared levels of CDH11 mRNA in human pancreatitis and pancreatic cancer tissues and cells, compared with normal pancreas, and measured levels of CDH11 protein in human and mouse pancreatic lesions and normal tissues. more...

(Submitter supplied) To understand the interplay between cancer and stroma, we performed single cell RNA-sequencing of PDAC cells admixed with stromal fibroblasts and defined different single cell populations with varying levels of proliferative and metastatic transcriptional states. PDAC cell behavior in vitro and in vivo on these phenotypic axes could be tuned with the proportion of stromal fibroblasts. These cell types were identified in human pancreatic tumors, and specific subpopulations were associated with worsened outcomes.

(Submitter supplied) Cancer associated fibroblasts (CAFs) are well known to strongly influence tumor development, progression, and metastasis. Their characteristics and prognostic gene signature in non-small cell lung cancer (NSCLC) patients have been recognized. Heterogeneity of CAFs has long been observed, however, the functional heterogeneity of CAFs between patients and their genetic basis are far less known. Here, we report the distinction of two CAF subtypes obtained from primary cultures of CAFs and matched normal fibroblasts (NFs) from 28 resected NSCLC. more...

(Submitter supplied) Pancreatic ductal adenocarcinoma (PDAC) is characterized by abundant stroma, the main cellular constituents of which are cancer-associated fibroblasts (CAFs). Heterogeneity in the PDAC CAF population was recently delineated demonstrating that both tumor-promoting and -suppressive activities co-exist in the stroma. Here, we aimed to identify biomarkers for the CAF population that contribute to a favorable outcome. more...

(Submitter supplied) Pancreatic ductal adenocarcinoma (PDAC) is characterized by a KRAS-driven inflammatory program and a desmoplastic stroma, which contribute to the profoundly chemoresistant phenotype. The tumor stroma contains an abundance of cancer-associated fibroblasts (CAFs), which engage in extensive paracrine crosstalk with tumor cells to perpetuate pro-tumorigenic inflammation. Interleukin-1α (IL1α), a pleiotropic, tumor cell-derived cytokine, plays a critical role in shaping the stromal landscape. more...

(Submitter supplied) Background & Aims. Pancreatic ductal adenocarcinoma (PDAC) has a hypoxic, immunosuppressive stroma, which contributes to its resistance to immune checkpoint blockade therapies. The hypoxia-inducible factors (HIFs) mediate the cellular response to hypoxia, but their role within the PDAC tumor microenvironment remains unknown. Methods. We used a dual recombinase mouse model to delete Hif1a or Hif2a in α-smooth muscle actin (αSMA)-expressing cancer-associated fibroblasts (CAFs) arising within spontaneous pancreatic tumors. more...

(Submitter supplied) Pancreatic cancer is characterized by heavy desmoplasia. Triptolide and its water-soluble pro-drug Minnelide are extremely efficient against pancreatic cancer in animal models. However, the effects of triptolide on pancreatic cancer stromal cells are largely unknown. The aim of this project is to indentify potential cellular functions that are affected by triptolide in pancreatic cancer associated fibroblasts.
