There are multiple mechanisms by which cells evade TGF-β-mediated growth inhibitory effects. In this report, we describe a novel mechanism by which cells become resistant to TGF-β-mediated growth suppression. Although having all the components of the TGF-β signaling pathway, different cell lines, RL, HaCaT, and BJAB, have different sensitivities toward TGF-β-induced growth suppression. The TGF-...

objective(s):transforming growth factor-β(tgf-β) is involved in colorectal cancer (crc). the sd-208 acts as an anti-cancer agent in different malignancies via tgf-β signaling. this work aims to show the effect of manipulation of tgf-β signaling on some mirnas implicated in crc. materials and methods: we investigated the effects of sd-208 on sw-48, a colon adenocarcinoma cell line. the cell line...

BACKGROUND Immunosuppressant cyclosporine-A induces gingival hyperplasia, which is characterized by increased fibroblast proliferation and overproduction of extracellular matrix components and regulated by transforming growth factor-beta (TGF-β). The TGF-β and Sonic hedgehog (Shh) pathways both mediate cell proliferation. Crosstalk between these pathways in cancer has recently been proposed, bu...

The transforming growth factor-β (TGF-β) is a family of structurally related proteins that comprises of TGF-β, activins/inhibins, and bone morphogenic proteins (BMPs). Members of the TGF-β family control numerous cellular functions including proliferation, apoptosis, differentiation, epithelial-mesenchymal transition (EMT), and migration. The first identified member, TGF-β is implicated in seve...

Human respiratory syncytial virus (RSV) is a lung tropic virus causing severe airway diseases including bronchiolitis and pneumonia among infants, children, and immuno-compromised individuals. RSV triggers transforming growth factor-β (TGF-β) production from lung epithelial cells and TGF-β facilitates RSV infection of these cells. However, it is still unknown whether RSV infected myeloid cells ...

Background: TGF-β has long been considered as the main inducer of Tregs in tumor microenvironment and is the reason for the aberrant number of Tregs in tumor-bearing individuals. Recently, it has been suggested that the enzyme arginase I is able to mediate the induction of Tregs in a TGF-β-independent fashion. The recombinant WW2/WW3 domains from smad ubiquitination regulatory factor 2 molecule...

Chronic wounds affect more than 2% of the population worldwide, with a significant burden on affected individuals, healthcare systems, and societies. A key regulator entire wound healing cascade is transforming growth factor beta (TGF-β), which regulates not only inflammation extracellular matrix formation but also revascularization. This present work aimed at characterizing tissues obtained fr...

INTRODUCTION Transforming growth factor-beta (TGF-β) is a well-known regulator of fibrosis and inflammation in many tissues. During embryonic development, TGF-β signaling induces expression of the transcription factor scleraxis, which promotes fibroblast proliferation and collagen synthesis in tendons. In skeletal muscle, TGF-β has been shown to induce atrophy and fibrosis, but the effect of TG...

Apoptosis in ovarian surface epithelial (OSE) cells is induced by transforming growth factor-beta (TGF-β). However, high-grade serous ovarian carcinomas (HGC) are refractory to the inhibitory functions of TGF-β; their invasiveness is up-regulated by TGF-β through epithelial-mesenchymal transition (EMT) activation. Serous borderline ovarian tumors (SBOT) have been recognized as distinct entities...

background: it has been documented that cytokines play important roles in the induction of normal functions of the placenta. it has been hypothesized that abnormal expression of the cytokines may be associated with unsuccessful pregnancy. objective: the aim of this study was to compare the serum levels of interleukin-17a (il-17a) and tumor growth factor (tgf-ß) in pre-term, term neonates, and t...
