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.

Study of transcriptional content in exosomes derived from untreated and growth factor-treated cultured cardiomyocytes (HL-1)

Project description:Introduction: Exosomes are nano-sized extracellular vesicles, released from various cells, which can stimulate or repress responses in target cells. We have recently shown that cultured cardiomyocytes release exosomes and that they, in turn, are involved in facilitating events in target cells by alteration of gene expression. We investigated whether external stimuli of the cardiomyocyte might influence the released exosome characteristics. Material and Methods: Exosomes were isolated from media collected from cultured cardiomyocyte (HL-1) cells with or without growth factor treatment (TGF-beta2 and PDGF-BB), with a series of differential centrifugations. The exosomes were characterized with dynamic light scattering (DLS) and Western blot and analysed with Illumina whole genome microarray gene expression. Results: An average size of 50-80 nm in diameter with no difference between treatment groups was found. Analysis of the mRNA content revealed 623 transcripts in the control group, 691 in the TGF-beta2-treated group and 362 in the PDGF-BB-treated group. 235 transcripts were common for all three groups. Conclusion: We conclude that there is a difference in mRNA content between exosomes derived from cultured cardiomyocytes stimulated with growth factors. We also conclude that all exosomes contain a basic package consisting of ribosomal transcripts and mRNAs coding for proteins with functions within the energy supply system. To study if the transcriptional content in exosomes derived from untreated and growth factor-treated cultured cardiomyocytes (HL-1) differ, and if so, can this difference be explained, 4 control (untreated) exosome samples, 4 TFG-beta2-treated cardiomyocyte-derived exosome samples and 4 PDGF-BB-treated cardiomyocyte-derived exosomes were studied.

Gene expression profiles of oral normal fibroblasts (NFs) and oral carcinoma-associated fibroblasts (CAFs)

Project description:This study aims to identify genes differentially expressed in oral CAFs with respect to their normal counterparts, i.e. oral NFs. We collected oral normal mucosal tissues and oral squamous cell carcinoma (OSCC) tissues from 12 healthy people and 12 OSCC patients, respectively, at West China Hospital of Stomatology, Sichuang University, P. R. China. The tissues were isolated, cultured and purified using standard protocols to obtain oral NFs and CAFs. Agilent 4×44K Whole Genome Oligo Microarrays were used to measure the gene expression profiles of the samples. Sample preparation and hybrid reactions were performed according to the manufacture’s instructions. RNA samples from NFs and CAFs were pooled respectively before hybridization. The chips were scanned and visualized using the Agilent DNA microarray scanner. Probe set intensities were measured using Agilent Feature Extraction software (version 10.5.1.1). Raw data were normalized in the Agilent GeneSpring GX software (version 11.0) using the Agilent FE one-color scenario (mainly median normalization). Oral NFs and CAFs were obtained from tissues derived from 12 healthy people undergoing plastic surgery and 12 OSCC patiens undergoing surgical resection. RNA samples from NFs and CAFs were pooled respectively before hybridization.
