Gene Expression Analysis of Cancer-Associated Fibroblast (CAF) compared to Normal Fibroblast (NF) [RNA-seq]

ABSTRACT: Analysis of differentially expressed genes in CAF associated with PDAC vs NF. Genetically engineered mice with spontaneous pancreas cancer were generated. Their genotype is Ptfa-cre/+:LSL KrasG12D/+;Tgfrb2flox/flox. Cancer associated fibroblasts were expanded in vitro from the tumors of these mice (CAF). Normal fibroblasts (NF) were also expanded from normal pancreas of mice. The experiement consists in comparing the expression profile of CAF vs. NF.

Human carcinoma-associated fibroblasts (CAF): co-culture with cancer cells vs. CAF only

Project description:Gene expression profiling of CAF co-cultured with human oral squamous cell carcinoma (OSCC) cells compared with mono-cultured CAF. To identify key molecular regulators expressed by carcinoma-associated fibroblasts (CAF) that promote cancer cell invasion, microarrays were performed by comparing co-cultured OSCC cells and CAF with monoculture controls. comparison 1: CAF co-cultured with OSCC vs. mono-cultured CAF comparison 2: OSCC co-cultured with CAF vs. mono-cultured OSCC 1.7X10(5) YD-10B OSCC cells and 1.7X10(5) CAF were seeded in the upper chamber and lower chamber, respectively, of 6-transwell plates containing collagen-coated 1 micrometer pore transmembrane filters (Becton Dickinson, Franklin Lakes, NJ, USA). Monoculture control samples were generated by culturing only CAF or OSCC on the same side of the filter as in the co-culture design.

Gene expression in CAF-1 leaves

Project description:Chromatin assembly factor CAF-1 is conserved in all eukaryotes. In contrast to animals, plant CAF-1 is viable. Here we probe effects of loss of CAF-1 on the transcriptome of non-diving cells. Fully expanded rosette leaf 6 was collected from 10 35-d-old plants grown in short day photoperiods of wild type Col and CAF-1 mutants fas2-4 were used for RNA extraction.

Androgen receptor functions as transcriptional repressor of Cancer Associated Fibroblast (CAF) activation [ChIP-seq]

Project description:The age-associated increase of cancer risk has been linked with stromal fibroblast senescence and early steps of Cancer Associated Fibroblast (CAF) activation. Surprisingly little is known about the role of androgen receptor (AR) signalling in this context. We show that AR expression is down-modulated in stromal fibroblasts underlying premalignant skin cancer lesions (actinic keratoses, AK) as well as in CAFs from the three major skin cancer types, squamous (SCC) and basal cell (BCC) carcinomas and melanomas. Decreased AR expression is linked to the concomitant down-modulation of CSL, key effector of canonical Notch signalling and global modulator of chromatin configuration, and it can be counteracted by treatment with BET inhibitors, which reverse CAF activation. Functionally, AR gene silencing in dermal fibroblasts results in p53-dependent senescence and induction of key CAF-effector genes, with AR physically converging with CSL in negative control of these genes. The findings are of functional significance as, in an orthotopic model of skin cancer, dermal fibroblasts with AR loss enhance significantly tumorigenicity of SCC and melanoma cells. As such, the findings establish AR as a novel potential target for stroma-focused cancer prevention and treatment.
