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...

BACKGROUND It is generally assumed that T cells do not produce active TGF-β since active TGF-β as measured in supernatants by ELISA without acidification is usually not detectable. However, it is possible that active TGF-β from T cells may take a special form which is not detectable by ELISA. METHODOLOGY/PRINCIPAL FINDINGS We constructed a TGF-β bioassay which can detect both soluble and memb...

The Runt related transcription factors (RUNX) are recognized as key players in suppressing or promoting tumor growth. RUNX3, a member of this family, is known as a tumor suppressor in many types of cancers, although such a paradigm was challenged by some researchers. The TGF-β pathway governs major upstream signals to activate RUNX3. RUNX3 protein consists of several regions and domains. The Ru...

Excessive transforming growth factor (TGF)-β signaling has been implicated in pulmonary hypoplasia associated with bronchopulmonary dysplasia, a chronic lung disease of human prematurity featuring pulmonary fibrosis. This implies that inhibitors of TGF-β could be useful therapeutic agents. Because exogenous TGF-β ligands are known to inhibit lung branching morphogenesis and cytodifferentiation ...

Transforming growth factor-β (TGF-β) signaling and TGF-β-promoted epithelial-to-mesenchymal transition (EMT) have been postulated to be the common pathway causing pulmonary fibrosis. However, the up- or downstreaming markers of TGF-β-induced EMT still need to be further recognized. In the present study, we investigated the regulation on Krüppel-like factor 4 (KLF-4) and plasminogen activator in...

AIM To explore the exact interaction between Notch and transforming growth factor (TGF)-β signaling in liver fibrosis. METHODS We established a rat model of liver fibrosis induced by concanavalin A. Peripheral blood mononuclear cells (PBMCs) were isolated from the modeled rats, and cultured with γ-secretase inhibitor DAPT and TGF-β inhibitor for 24 h. The mRNA levels of Notch and TGF-β signal...

Abstract Introduction High-grade primary brain tumors cause serious morbidity and mortality. This study aimed to investigate the role of transforming growth factor beta (TGF-β) suppressor mothers against decapentaplegic (Smad) receptors in high-grade tumors. Material Method Thirteen patients with a pathological diagnosis glioblastoma multiforme were included study. Pathological preparations eac...

Transforming growth factor-beta (TGF-β) functions as a potent proliferation inhibitor and apoptosis inducer in the early stages of breast cancer, yet promotes cancer aggressiveness in the advanced stages. The dual effect of TGF-β on cancer development is known as TGF-β paradox, and the remarkable functional conversion of TGF-β is a pivotal and controversial phenomenon that has been widely inves...
