Expression data of HNSCC cell lines grown without and with patient-matched CAFs in 3D

Project description:Cancer associated fibroblasts (CAFs) are the major cellular component of the tumor microenvironment and they have been shown to stimulate tumor growth, epithelial-to-mesenchymal transition (EMT), invasion and radio-resistance. We used microarrays to investigate the influence of CAFs on the gene expression profile of HNSCC cells in 3D co-cultures

Gene expression profiling of HNSCC cells derived from primary and matched metastatic tumors

Project description:To look at genes/pathways differentially expressed in metastatic and primary tumor cells we performed global gene expression profiling of the 3 sets of HNSCC lines derived from primary tumors and matched metastatic sites. Illumina HT-12 v4 BeadChip arrays were used. The data suggest that HNSCC lines derived from metastatic sites exhibit phenotypes distinct from those found in cells derived from the corresponding primary tumors. Metastatic cell lines upregulated several pathways involved in stem cell self-renewal, invasion and migration, which are well known characteristics of metastatic progression. We conclude that the cell lines derived from primary patient tumors and matched metastatic sites represent a reliable model to study HNSCC metastasis.

Next generation sequencing showing miRNA profiles of exosomes derived from DHT-treated CAFs and matched ETOH-treated CAFs

Project description:Background: Androgen deprivation therapy (ADT) is the backbone of therapy for advanced prostate cancer (PCa). Despite the good initial response, castration resistance and metastatic progression will inevitably occur. Cancer-associated fibroblasts (CAFs) may be implicated in promoting metastasis of PCa after ADT. Our aim is to investigate the role and mechanism of CAF-derived exosomes involving in metastasis of PCa after ADT. Methods: PCa cells were co-cultured with exosomes derived from DHT-treated or ETOH-treated CAFs, and their migration and invasion differences under castration condition were examined both in vitro and in vivo. The miRNA profiles of exosomes derived from DHT-treated CAFs and matched ETOH-treated CAFs were analysed via next generation sequencing. The transfer of exosomal miR-146a-5p from CAFs to PCa cells was identified by fluorescent microscopy. The function and direct target gene of exosomal miR-146a-5p in PCa cells were confirmed through Transwell assays, luciferase reporter, and western blot. Findings: Compared with DHT-treated CAFs, exosomes derived from ETOH-treated CAFs dramatically increase migration and invasion of PCa cells under castration condition. MiR-146a-5p level in exosomes from ETOH-treated CAFs was significantly reduced. The loss of miR-146a-5p may strengthen the epithelial-mesenchymal transition (EMT) to accelerate cancer cells metastasis by modulating epidermal growth factor receptor (EGFR)/ERK pathway. Interpretation: CAFs-derived exosomal miR-146a-5p confers metastasis in PCa cells under ADT through the EGFR/ERK pathway and it may present a new treatment for PCa.

Expression data from gemcitabine treated pancreatic CAFs

Project description: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. Gene expression differences between treatment naÃ¯ve CAFs (N-CAFs) and R-CAFs were compared by array analysis. Immortalized human pancreatic CAFs were grown for 30 days in either control media or media containing 100nM gemcitabine. RNA was then isolated and hybidized on U133 Plus 2.0 Affymetrix arrays.
