BACKGROUND Transforming growth factor-beta1 (TGF-beta1) is the major profibrotic cytokine involved in many renal diseases, and urinary TGF-beta1 reflects intrarenal TGF-beta1 production. Urinary TGF-beta1 excretion is reported to be significantly increased in patients with immunoglobulin A (IgA) nephropathy. The aim of the present study was to compare the effects of losartan and amlodipine on p...
Recent results support a two-step model for endoderm formation in amphibian embryos, in which endoderm is initially specified by localised maternal factors, including the transcription factor VegT, but is then maintained by extracellular signalling molecules of the transforming growth factor-beta family.
After injury to the CNS, extracellular matrix molecules such as tenascin are upregulated around the injury site and may be involved in inhibition of axon growth. In the present study, astrocytes were investigated to determine which cell types, growth factors, or cytokines are responsible for the injury-induced regulation of tenascin. The addition of activated macrophage- or microglial-condition...
BACKGROUND Familial sick sinus syndrome is associated with gene mutations and dysfunction of ion channels. In contrast, degenerative fibrosis of the sinus node tissue plays an important role in the pathogenesis of acquired sick sinus syndrome. There is a close relationship between transforming growth factor-β1 mediated cardiac fibrosis and acquired arrhythmia. It is of interest to examine wheth...
Transforming growth factor-β1 is considered a key contributor to the progression of breast cancer. MicroRNAs are important factors in the development and progression of many malignancies. In the present study, upon studies of breast cancer cell lines and tissues, we showed that microRNA -196a-3p is decreased by transforming growth factor-β1 in breast cancer cells and associated with breast canc...
Lievens and colleagues report an important finding that helps to elucidate the role of transforming growth factor b (TGFb)b in atherosclerotic plaque formation. TGFb is a widely expressed cytokine produced by smooth muscle cells, endothelial cells, monocytes, macrophages, and T cells. Clinical studies suggest that TGFb is antiatherosclerotic, citing a negative correlation between plasma TGFb co...
