Project description:To elucidate the expression file under TGF-β1 treatment , we performed RNA-seq on HK2 cells treated with TGF-β or not We then performed gene expression profiling analysis using data obtained from RNA-seq of HK2 cells untreated or treated with TGF-β1 (5ng/ml) for 24 h

Project description:To elucidate how TGF-β1 regulates translation, we treated human lung fibroblasts (HLF) with TGF-β1 and used RNA-seq to determine the effect of TGF-β1 on total RNAs, and mRNA polysome/monosome ratios.

Project description:These data show that the genes that distinguish myofibroblasts from fibroblasts are myriad, and that some genes not traditionally associated with myofibroblast differentiation may serve as novel therapeutic targets for fibrosing disorders. Gene expression levels were assessed from total RNA on the Affymetrix U219 microarray. Here, we use transforming growth factor-β1 (TGF-β1) and prostaglandin E2 (PGE2), which has recently been shown to reverse myofibroblast differentiation, to investigate the transcriptomic changes that occur during TGF-β1-induced differentiation and PGE2-induced de-differentiation of myofibroblasts.

Project description:Purpose: To compare the transcriptome profiling of control cells or the A549 cells in the presence or absence of acetate following TGF-β1 stimulation. Methods: A549 cells were treated with control, TGF-β1 or TGF-β1 plus acetate for 2 days. And then, we performed RNA sequencing for transcription profiling of control cells or the A549 cells in the presence or absence of acetate following TGF-β1 stimulation. The raw data were processed with bcl2fastq software and HISAT2. Results: From the transcriptome profiling and analysis, we got gene expression data of control group and in the presence or absence of acetate following TGF-β1 stimulation using A549 cells. Conclusion: The gene expression data revealed the transcriptome variation by TGF-β1 treatment and acetate can reverse TGF-β1 effect.

Project description:Fibrotic diseases have significant health impact and have been associated with differentiation of the resident fibroblasts into myofibroblasts. In particular, stiffened extracellular matrix and TGF-β1 in fibrotic lesions have been shown to promote pathogenic myofibroblast activation and progression of fibrosis in various tissues. To better understand the roles of mechanical and chemical cues on myofibroblast differentiation and how they may crosstalk, we cultured primary valvular interstitial cells (VICs) isolated from porcine aortic valves and studied how traditional TCPS culture, which presents a non-physiologically stiff environment, and TGF-β1 affect native VIC phenotypes. We carried out gene expression profiling using porcine genome microarrays from Affymetrix and found that traditional TCPS culture induces major changes in gene expression of native VICs, rendering these cells more activated and similar to cells treated with TGF-β1. We also monitored time-dependent effects induced by TGF-β1 by examining gene expression changes induced by TGF-β1 at 8 hours and 24 hours. Porcine aortic VICs were isolated and cultured with or without TGF-β1 treatment for RNA extraction and hybridization on Affymetrix microarrays. We included 3 biological replicates for each condition. P0 VICs were freshly isolated cells which had not been cultured. P2 VICs were cells that had been passaged 2 times and cultured on plastic plates in low serum media. Some of the P2 VICs were treated with TGF-β1 at 5ng/ml for 8 hours or 24 hours. All the control and TGF-β1-treated conditions were collected at the same time on day 3 of culture.

Project description:Extracellular vesicles play an important role in human cellular communication. Here, we show that human and mouse monocytes release TGF-β1-transporting vesicles in response to the pathogenic fungus Candida albicans. Soluble beta-glucan from Candida albicans binds to complement receptor 3 (CR3, CD11b/CD18) on monocytes and induces the release of TGF-β1-transporting vesicles. CR3-dependence is demonstrated using CR3-deficient (CD11b knockout) monocytes generated by CRISPR-CAS9 genome editing and isolated from CR3-deficient (CD11b knockout) mice. Isolated vesicles dampen the pro-inflammatory response in human M1-macrophages as well as in whole blood. Binding of the vesicle-transported TGF-β1 to the TGF-β receptor inhibits IL-1β gene transcription via the SMAD7 pathway in whole blood and induces TGF-β1 transcription in endothelial cells. Inhibition of TGF-β1 relieved the suppression of such proinflammatory effect. Notably, human opsonized apoptotic bodies induce similar TGF-β1-transporting vesicles in monocytes, suggesting that the early immune response is suppressed through this newly identified CR3-dependent anti-inflammatory vesicle pathway.

Project description:Fushen Granule (FSG), a Chinese medicinal formular, was clinically used to improve the peritoneal dialysis (PD) efficiency in ESRD patients received PD treatment. However, its mechanisms of anti-fibrotic effect in peritoneal fibrosis (PF) has not been studied yet. In this work, we used TGF-β1-stimulated MeT5A cells to mimic the process of PF in vitro, and Label-free proteomics and bioinformatics analysis were used to explored the underlying targets and pathways of FSG on TGF-β1-treated MeT5A cells

Project description:Transforming growth factor beta 1 (TGF-β1) is the most extensively studied growth factor in dentin-pulp complex, with pleiotropic effects on pulp response and healing. Our main objective was to analyze the expression profile of pulp tissue and odontoblasts, and the effects of TGF-β1 on these profiles in cultured human pulp and odontoblasts with a specific interest in the anti- and pro-inflammatory cytokines. Keywords: Response to TGF-β1 treatment

Project description:We studied miRNAs and their gene targets affecting SARS-CoV-2 pathogenesis in CF airway epithelial cell models in response to TGF-β1. Small RNAseq in CF human bronchial epithelial cell line treated with TGF-β1 and miRNA profiling characterized TGF-β1 effects on the SARS-CoV-2 pathogenesis pathways. Among the effectors, we identified and validated two miRNAs targeting ACE2 mRNA using different CF and non-CF human bronchial epithelial cell models. We have shown that TGF-β1 inhibits ACE2 expression by miR-136-3p and miR-369-5p. ACE2 levels were higher in cells expressing F508del-CFTR, compared to wild-type(WT)-CFTR and TGF-β1 inhibited ACE2 in both cell types. The ACE2 protein levels were still higher in CF, compared to non-CF cells after TGF-β1 treatment. TGF-β1 prevented the functional rescue of F508del-CFTR by ETI in primary human bronchial epithelial cells while ETI did not prevent the TGF-β1 inhibition of ACE2 protein. Finally, TGF-β1 reduced binding of ACE2 to the recombinant monomeric spike RBD. Our results may help to explain, at least in part, the role of TGF-β1 on the SARS-CoV-2 entry via ACE2 in the CF and non-CF airway.

Project description:The human hepatic stellate cell line LX2 was treated with 8 Gy X-ray irradiation and/or 2ng/ml recombinant human TGF-β1. The iTRAQ-based high throughput quantitative proteomic approach was used to obtain a comprehensive view of the protein ensembles affected by irradiation and/or TGF-β1 treatment on LX2. This study provides clues for further investigation of the mechanisms behind radiation-induced liver fibrosis.
