Osthole prevents cerebral ischemia–reperfusion injury via the Notch signaling pathway

mTORC1 Prevents Preosteoblast Differentiation through the Notch Signaling Pathway

The mechanistic target of rapamycin (mTOR) integrates both intracellular and extracellular signals to regulate cell growth and metabolism. However, the role of mTOR signaling in osteoblast differentiation and bone formation is undefined, and the underlying mechanisms have not been elucidated. Here, we report that activation of mTOR complex 1 (mTORC1) is required for preosteoblast proliferation;...

Artesunate ameliorates lung fibrosis via inhibiting the Notch signaling pathway

The present study aimed to determine the underlying molecular mechanism of the antifibrotic effect of artesunate in pulmonary fibrosis (PF). Primary lung fibroblasts were isolated from the lung tissues of rats, and treated with artesunate (8 µg/ml) and transforming growth factor (TGF)-β1 (5 ng/ml). For in vivo experiments, the rats were administered bleomycin intratracheally, followed by daily ...

Notch signaling: a common pathway of injury in podocytopathies?

The Notch signaling pathway comprises a family of transmembrane receptors, ligands, negative and positive modifiers, and transcription factors with regulatory activity in multiple cellular processes, including cell fate determination, development, differentiation, proliferation, apoptosis, and regeneration. A critical step in the activation of the Notch receptor is proteolytic cleavage of its i...

SnapShot: Notch Signaling Pathway

Neuroprotection of Osthole against Cerebral Ischemia/Reperfusion Injury through an Anti-apoptotic Pathway in Rats.

Cerebral ischemia/reperfusion (I/R) injury is a major cause of acute brain injury. The pathogenetic mechanisms underlying I/R injury involve apoptosis, inflammation and oxidative stress. Osthole-a plant coumarin compound-has been reported to protect against focal cerebral I/R-induced injury in rats. However, the mechanism remains unknown. Here we hypothesize that osthole acts through inhibition...
