Project description:The survival of isolated metastatic cells and expansion into macroscopic tumour has been recognized as a limiting step for metastasis formation in several cancer types yet the determinants of this process remain largely uncharacterized. In colorectal cancer (CRC), we identify a transcriptional programme in tumour-associated stromal cells, which is intimately linked to a high risk of developing recurrent disease after therapy. A large proportion of CRCs display mutational inactivation of the TGF-beta pathway but paradoxically they are characterized by high TGF-beta production. In these tumours, TGF-beta instructs a transcriptional programme in stromal cells, which confers a high risk of developing metastatic disease. We quantified the association of TGF-beta-activated fibroblasts with disease progression. To this end, we used as surrogates the gene expression programme upregulated by addition of TGF-beta to normal colon mucosa-derived fibroblasts (CCD-Co-18) in culture. CCD-Co-18 were seeded at 60% confluence and treated with TGF-β1. Gene expression profiles were measured in duplicate using HG-U133 plus 2.0. We used RMA background correction, quantile normalization and RMA summarization (Gautier et al., 2004). A TGF-β response signature was obtained by selecting genes with limma P-value < 0.05 and at least two fold up-regulation in TGF-β treated fibroblasts.

Project description:Advanced ovarian cancer is the most lethal gynecologic malignancy in the United States. Ovarian cancer cells are known to have diminished response to TGF-beta, but it remains unclear whether TGF-beta can modulate ovarian cancer cell growth in an indirect manner through cancer-associated fibroblasts (CAFs). Using transcriptome profiling analyses on TGF-beta-treated ovarian fibroblasts, we identified a TGF-beta-responsive gene signature in ovarian fibroblasts. Identifying TGF-beta-regulated genes in the ovarian microenvironment helps in understanding the role of TGF-beta in ovarian cancer progression. The human telomerase-immortalized ovarian fibroblast line NOF151 was treated with 5ng/mL of either TGF-beta-1 or TGF-beta-2. Total RNA was isolated from control samples and TGF-beta-treated fibroblasts samples at 48 hours post-treatment, followed by cDNA synthesis, IVT and biotin labeling. Samples were then hybridized onto Affymetrix Human Genome U133 Plus 2.0 microarrays. For each treatment group, three independent samples were prepared for the microarray experiment.

Project description:Activated hepatic stellate cells/myofibroblasts induced by TGF-β within the hepatic microenvironment are crucial determinants for cell growth and liver metastasis of colorectal cancer. Notably, TGF-β receptor II serves as the initiator of the received signal, and its membrane localization, internalization, degradation, and trafficking play a decisive role in determining the duration and intensity of TGF-β/SMAD signaling. This study aimed to identify the proteins that interact with TGF-β receptor II and clarify the underlying mechanisms of myofibroblastic activation of HSCs.
