Hepatocellular carcinoma (HCC) occurs subsequent to liver injury, where regenerative hepatocytes develop into a dysplastic nodule and then early HCC, supporting the multistep hepatocarcinogenesis theory. Molecular alterations such as the p53 mutation, p16 gene silencing, and AKT signaling activation are found in the late stage of HCC progression. The overexpression of some marker molecules is o...

Glioblastoma are among the most angiogenic tumors. The molecular mechanisms that control blood vessel formation by endothelial cells (EC) in glioblastoma remain incompletely understood. Transforming growth factor-β (TGF-β) is a key regulatory cytokine that has proinvasive and stemness-maintaining autocrine properties in glioblastoma and confers immunosuppression to the tumor microenvironment. H...

Transforming growth factor-β (TGF-β) stimulates α1(I) collagen mRNA synthesis in human lung fibroblasts through a mechanism that is partially sensitive to cycloheximide and that may involve synthesis of connective tissue growth factor (CTGF). Northern blot analyses indicate that TGF-β stimulates time- and dose-dependent increases in CTGF mRNA. In TGF-β-stimulated fibroblasts, maximal levels of ...

variety of positive as well as negative regulatory signals are provided by antigen presenting cell in particular by dendritic cells. in this research, we studied the capacity of dendritic cells to expand antigen-specific t regulatory cells.we also investigated the role of tgf-beta in induction inhibitory functions of dendritic cells in mixed leukocyte reactions. dendritic cells were generated f...

WNT-5A, a key player in embryonic development and post-natal homeostasis, has been associated with a myriad of pathological conditions including malignant, fibroproliferative and inflammatory disorders. Previously, we have identified WNT-5A as a transcriptional target of TGF-β in airway smooth muscle cells and demonstrated its function as a mediator of airway remodeling. Here, we investigated t...

Background CAR T cell therapy remains ineffective in solid tumors. Scarce infiltration and suppression at the tumor site are two notable limitations. regulatory (Treg) cells capable of suppressing effective anti-tumor responses through inhibitory factors such as transforming growth factor β (TGF-β). Treg expressing C-C chemokine receptor 8 (CCR8) have been found to accumulate correlate with poo...

Transforming growth factor β (TGF-β) signaling facilitates tumor development during the advanced stages of tumorigenesis, but induces cell-cycle arrest for tumor suppression during the early stages. However, the mechanism of functional switching of TGF-β is still unknown, and it is unclear whether inhibition of TGF-β signaling results amelioration or exacerbation of cancers. Here we show that t...

BACKGROUND TGF-β is induced in the vasculature with aging suggesting that high plasma TGF-β levels may be a risk factor for chronic kidney disease (CKD) in older adults. METHODS We conducted a cross-sectional analysis of the association between plasma TGF-β levels and CKD including data for 1722 older adults who had participated in the 1996/97 visit of the Cardiovascular Health Study (CHS). P...

The objective of this study was to investigate the relationship between serum levels of OPG, TGF- β 1, and TGF- β 2 and BMD decrease rate (BDR) in native Chinese women. This cross-sectional study was performed on 465 healthy native Chinese women aged 35-80 years. Serum levels of OPG, TGF- β 1, and TGF- β 2 were determined. BDR was measured by DXA at the posteroanterior spine, hip, and distal fo...
