Project description:RIE (rat intestinal epithelial) cells treated with 2 ng/ml of TGF-beta-1 for 1 hr were compared to control cells. The experiment was performed under identical conditions four times: RIE vs RIE - TGF-beta #1-#4. RIE-Ras cells were established by stable transfection of the parental cells with pSV2-H-Ras(12V) which contain human sequences encoding the constitutively active H-Ras(12V) protein. RIE-Ras cells treated with 2 ng/ml of TGF-beta-1 for 1 hr were compared to control cells. The experiment was performed four times under identical conditions (RIE-Ras vs RIE-RAS TGF-beta #1-#4). Keywords = TGF-beta Keywords = rat Keywords = intestinal epithelial cells Keywords: parallel sample

Project description:microRNA profiling of rat small intestinal crypt cell IEC-6. Comparing control untreated with cells treated with transforming growth factor-beta (TGF-beta). TGF-beta stimulated cell differentiation, as observed in the stimulation of intestinal epithelial cell markers (alkaline phophotase, villin, aminopeptidase N, etc.). Two condition experiment. Control vs TGF-beta treatment. Biological replicates: 3 control, 3 treated. Independently grown and harvested. One replicate per array

Project description:Epithelial-to-mesenchymal transitions (EMT) play prominent roles during development, regeneration and tumor progression. EMTs are triggered by TGF-β, RAS and other signals that cooperatively induce the expression of master EMT transcription factors such as SNAIL. Here, we elucidate how the TGF-β and RAS pathways jointly trigger EMTs and tie them to broader developmental programs. We identify RAS response element binding protein 1 (RREB1) as a critical partner of TGF-β-activated SMAD transcription factors in driving SNAIL expression and EMT program in mammary gland epithelial cells.

Project description:RATIONALE: Measuring levels of transforming growth factor-beta (TGF-beta) in the blood of patients with epithelial cancers (head and neck, lung, breast, colorectal, and prostate) may help doctors predict how patients will respond to treatment with radiation therapy.
PURPOSE: This research study is measuring levels of TGF-beta in patients with epithelial cancers who are undergoing radiation therapy.

EMTs are triggered by TGF-β, RAS and other signals that cooperatively induce the expression of master EMT transcription factors such as SNAIL. Here, we elucidate how the TGF-β and RAS pathways jointly trigger EMTs and tie them to broader developmental programs. We identify RAS response element binding protein 1 (RREB1) as a critical partner of TGF-β-activated SMAD transcription factors in driving SNAIL expression in pancreatic pre-malignant epithelial cells, lung adenocarcinoma cells, and embryonic stem cells. Moreover, SMADs and RREB1 also drive EMT-associated fibrogenic programs in epithelial cells and mesendoderm differentiation in pluripotent embryonic cells. These findings illuminate the orchestration of EMT associated programs in gastrulation, fibrosis, and cancer.

Project description:SMAD4, a key mediator of TGF-beta signaling, plays a crucial role in T cells to prevent chronic intestinal inflammation through unknown mechanisms. We reveal that SMAD4 in CD8 T cells prevents chronic intestinal inflammation primarily in a TGF-beta-independent manner. Mechanistically, SMAD4, in CD8 T cells, acts as a basal and tonic repressor of TGF-beta-target genes at the transcriptional and epigenetic level, prior to any TGF-beta signal. SMAD4 deletion affects aberrantly a wide range of TGF-beta-target genes, thereby promoting accumulation and epithelial retention of CD8.alpha.beta T cells inversely to total TGF-beta signaling disruption. Moreover, SMAD4 deletion unleashes the expression of TGF-beta-signaling-repressors and hampers TGF-β-mediated CD8 T cell immunosuppression, eliciting their chronic activation. Hence, in a feedforward mechanism, SMAD4 both blocks the TGF-beta signature in CD8 T cells and pre-sensitizes them to TGF-beta.
