Resveratrol inhibits hepatic stellate cell activation by regulating autophagy and apoptosis through the SIRT1 and JNK signaling pathways

Journal of Food Biochemistry, Volume 46, Issue 12, December 2022., 2022
Resveratrol inhibited hepatic stellate cells (HSCs) activation by inducing autophagy and apoptosis in a dose‐dependent manner. The Sirtuin1 (SIRT1) inhibitor EX527 reversed autophagy, and the c‐Jun N‐terminal kinase (JNK) inhibitor SP600125 reversed both autophagy and apoptosis induced by resveratrol.

A three-state kinetic mechanism for scaffold mediated signal transduction [PDF]

, 2008
Signaling events in eukaryotic cells are often guided by a scaffolding protein. Scaffold proteins assemble multiple proteins in a spatially localized signaling complex and exert numerous physical effects on signaling pathways. To study these effects, we consider a minimal, three-state kinetic model of scaffold mediated kinase activation.

Fc gamma receptor cross-linking activates p42, p38, and JNK/SAPK mitogen-activated protein kinases in murine macrophages: role for p42MAPK in Fc gamma receptor-stimulated TNF-alpha synthesis.

Journal of Immunology, 1997
Fc gamma R cross-linking on murine macrophages resulted in the activation of mitogen-activated protein kinase (MAPK) family members p42MAPK, p38, and c-Jun NH2-terminal kinase (JNK)/stress-activated protein kinase (SAPK).

Positive feedback loop between MAPK and aquaporin 7 regulates autophagy and apoptosis induced by palmitate in RIN‐m5f cells

FEBS Open Bio, EarlyView.
T2DM is characterized by peripheral blood insulin resistance and progressive pancreatic β‐cell dysfunction. Here, we showed that AQP7, the only aquaglyceroporin protein, regulates autophagy and apoptosis in pancreatic β‐cells. We propose the existence of a positive feedback loop between MAPK signaling and AQP7 that regulates autophagy and apoptosis in ...

Bioactive food components and their inhibitory actions in multiple platelet pathways

Journal of Food Biochemistry, Volume 46, Issue 12, December 2022., 2022
A comprehensive overview of platelet multifunctional roles in CVD and other diseases and the effects of food components' modulatory effects are described. Abstract In addition to hemostasis and thrombosis, blood platelets are involved in various processes such as inflammation, infection, immunobiology, cancer metastasis, wound repair and angiogenesis ...

Differential regulation of anti-inflammatory genes by p38 MAP kinase and MAP kinase kinase 6. [PDF]

, 2014
BackgroundConventional p38α inhibitors have limited efficacy in rheumatoid arthritis, possibly because p38 blockade suppresses the counter-regulatory mechanisms that limit inflammation.

Cortactin: A universal host cytoskeletal target of Gram‐negative and Gram‐positive bacterial pathogens

Molecular Microbiology, Volume 118, Issue 6, Page 623-636, December 2022., 2022
In host‐pathogen interactions, actin‐cytoskeletal dynamics play a crucial role in successful adherence, invasion, and intracellular motility by many intruding microbes. To achieve this goal, bacterial pathogens target major host regulators, one of which is the key actin‐binding protein and class‐II actin nucleation‐promoting factor cortactin.

Ginkgo biloba extract individually inhibits JNK activation and induces c-Jun degradation in human chondrocytes: potential therapeutics for osteoarthritis. [PDF]

PLoS ONE, 2013
Osteoarthritis (OA) is a common joint disorder with varying degrees of inflammation. The ideal anti-OA drug should have immunomodulatory effects while at the same time having limited or no toxicity.

Protein Kinase C-related Kinase and ROCK Are Required for Thrombin-induced Endothelial Cell Permeability Downstream from G{alpha}12/13 and G{alpha}11/q [PDF]

The Journal of Biological Chemistry 283, 44 (2008) 29888-96, 2008
Increase in vascular permeability occurs under many physiological conditions and is central in diverse human pathologies. Thrombin is a pro-coagulant serine protease, which causes the local loss of endothelial barrier integrity thereby enabling the rapid extravasation of plasma proteins and the local formation of fibrin-containing clots.
