Next Generation Sequencing of H292 cell line cultured with CAFs CM or SL-CAFs CM

Project description:Cancer cell radioresistance is the primary cause of the decreased curability of non-small cell lung cancer (NSCLC) observed in patients receiving definitive radiotherapy (RT). Following RT, a set of microenvironmental stress responses is triggered, including cell senescence. However, cell senescence is often ignored in designing effective strategies to resolve cancer cell radioresistance. Herein, we identified the senescence-like characteristics of cancer-associated fibroblasts (CAFs) post RT and clarified the formidable ability of senescence-like CAFs in promoting NSCLC cells proliferation and radioresistance through the JAK/STAT pathway. Specific induction of senescence-like CAFs apoptosis using FOXO4-DRI, a FOXO4-p53 interfering peptide, resulted in remarkable effects on radiosensitizing NSCLC cells in vitro and in vivo. In addition, our study also discovered the obvious therapeutic effect of FOXO4-DRI on alleviating radiation-induced pulmonary fibrosis (RIPF) by targeting senescence-like fibroblasts in vivo. In conclusion, by targeting senescence, we offer a new strategy which simultaneously decreases radioresistance of NSCLC and the incidence of RIPF.

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.

Next Generation Sequencing Facilitates Quantitative Analysis of EG7-CAFs and MSCs Transcriptomes

Project description:Purpose: The goals of this study are to compare EG7 - CAFs (cancer-associated fibroblasts) and MSCs (mesenchymal stem cells) transcriptome profiling (RNA-seq) generated from Next-generation Sequencing (NGS) to perform optimal high-throughput data analysis Methods: mRNA profiles of CAFs were purified from EG7 tumor bearing mice and early passage (p6) murine MSCs purchased from Cyagen were cultured in DMEM for no more than 2 passages were generated by deep sequencing, in triplicate, using Illumina HiSeq 3000. The sequence reads that passed quality filters were analyzed at the transcript isoform level TopHat followed by Cufflinks Results: Comparative high throughput RNA-sequencing (seq) analysis of purified EG7-CAFs and the early passage murine MSCs, which are thought to be precursors for some CAFs and used as the control for normal mesenchymal cells, by using an optimized data analysis workflow, we mapped about 50 million sequence reads per sample to the mouse genome (build mm10) and identified 11,839 transcripts with TopHat workflow. Approximately 1584 of the transcripts showed differential expression between the EG7 - CAFs and MSCs, with a fold change ≥ 2 and p value <0.01 Conclusions: Our results clearly support the notion that CAFs are transcriptionally different from MSCs in various pathways and biological processes associated with immune modulation, inflammation, hypoxia, and activation of oncogenic pathways

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.

MiRNA expression analysis of cancer-associated fibroblasts (CAFs) and normal fibroblasts (NFs) in breast cancer

Project description:To identify miRNA differentially expressed in CAFs vs matched NFs and analyze the heterogeneity of miRNA expression profiles in the two kinds of cells, we established primary cultures of CAFs and paired NFs from six resected breast tumor tissue without any radiotherapy and chemotherapy treatment. Paired CAFs and NFs from six primary human breast carcinoma specimens were cultured,the third passage of primary cells was used in the experiments.

Next Generation Sequencing Quantitative Analysis of altered expression of genes in BCa cells-induced PDGFRα+ITGA11+ CAFs and other CAFs

Project description:The cellular diversity of stromal compartment within the tumor microenvironment might change dynamically as tumors evolve that allowing distant dissemination of tumor cells and informing the treatment options. We used single cell RNA sequencing (scRNA-seq) to provide a detailed insight of cellular components feature in bladder cancer and identify that PDGFRα+ITGA11+ CAFs were essential for lymphatic metastasis of bladder cancer. To identify molecular mechanism of PDGFRα+ITGA11+ CAFs formation, next generation sequencing (NSG) was performed to explore the upregulated genes in bladder cancer-induced PDGFRα+ITGA11+ CAFs.
