Human milk contains substantial amounts of transforming growth factor (TGF)-β, particularly the isoform TGF-β2. We previously showed in preclinical models that enterally administered TGF-β2 can protect against necrotizing enterocolitis (NEC), an inflammatory bowel necrosis of premature infants. In this study we hypothesized that premature infants remain at higher risk of NEC than full-term infa...

TGF-β potently induces apoptosis in Burkitt’s Lymphoma (BL) cell lines and in explanted primary human B lymphocytes. The physiological relevance and mechanism of TGF-β-mediated apoptosis induction in these cells remains to be determined. Here we demonstrate the requirement for TGF-β-mediated regulation of BIK and BCL-XL to activate an intrinsic apoptotic pathway in centroblastic BL cells. TGF-β...

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...
