Cathepsins B and D drive hepatic stellate cell proliferation and promote their fibrogenic potential.
UNLABELLED Cathepsins have been best characterized in tumorigenesis and cell death and implicated in liver fibrosis; however, whether cathepsins directly regulate hepatic stellate cell (HSC) activation and proliferation, hence modulating their fibrogenic potential, is largely unknown. Here, we show that expression of cathepsin B (CtsB) and cathepsin D (CtsD) is negligible in quiescent HSCs but ...
متن کاملThe role of focal adhesion kinase-phosphatidylinositol 3-kinase-akt signaling in hepatic stellate cell proliferation and type I collagen expression.
Following a fibrogenic stimulus, the hepatic stellate cell (HSC) undergoes a complex activation process associated with increased cell proliferation and excess deposition of type I collagen. The focal adhesion kinase (FAK)-phosphatidylinositol 3-kinase (PI3K)-Akt signaling pathway is activated by platelet-derived growth factor (PDGF) in several cell types. We investigated the role of the FAK-PI...
متن کاملImmortal hepatic stellate cell lines: useful tools to study hepatic stellate cell biology and function?
At the cellular level, the activation and transdifferentiation of quiescent hepatic stellate cells (HSC) into myofibroblasts is the key process involved in hepatic fibrogenesis that is associated with an increased and altered deposition of extracellular matrix components in the liver. The temporal sequence of molecular events associated with stellate cell activation turned out to be appropriate...
متن کامل20S-Protopanaxadiol, an aglycosylated ginsenoside metabolite, induces hepatic stellate cell apoptosis through liver kinase B1–AMP-activated protein kinase activation
BACKGROUND Previously, we reported that Korean Red Ginseng inhibited liver fibrosis in mice and reduced the expressions of fibrogenic genes in hepatic stellate cells (HSCs). The present study was undertaken to identify the major ginsenoside responsible for reducing the numbers of HSCs and the underlying mechanism involved. METHODS Using LX-2 cells (a human immortalized HSC line) and primary a...
متن کاملTranscriptional regulation of hepatic stellate cell activation.
The hepatic stellate cell (HSC) is now well established as the key cellular element involved in the development of hepatic fibrosis and because of this there is considerable interest in establishing the molecular events that trigger and perpetuate HSC activation. HSC activation at the level of gene transcription requires the coordinated activity of several key transcriptional regulators of the ...
