The oxidized phospholipid PGPC impairs endothelial function by promoting endothelial cell ferroptosis via FABP3.

Ferroptosis is a novel cell death mechanism that is mediated by iron-dependent lipid peroxidation. It may be involved in atherosclerosis development. Products of phospholipid oxidation play a key role in atherosclerosis.

Spermidine-enhanced autophagic flux improves cardiac dysfunction following myocardial infarction by targeting the AMPK/mTOR signalling pathway.

Background And Purpose: Spermidine, a natural polyamine, is abundant in mammalian cells and is involved in cell growth, proliferation, and regeneration. Recently, oral spermidine supplements were cardioprotective in age-related cardiac dysfunction, through enhancing autophagic flux. However, the effect of spermidine on myocardial injury and cardiac dysfunction following myocardial infarction (MI) remains unknown.

[High glucose promotes vascular smooth muscle cell calcification by activating WNT signaling pathway].

Objective: To investigate whether high glucose-induced vascular calcification is associated with WNT signaling pathway.

Methods: An in vitro model of human vascular smooth muscle cell (VSMC) calcification was induced by exposure of the cells to high glucose. The expressions of WNT signal molecules and bone-related proteins including Cbfa1, Osx, OCN and BMP2 were analyzed with qRT-PCR, and the cell calcification was assessed by alizarin red staining.

[Recent advances of research on warming therapy].

Therapeutic method is an important component of traditional Chinese medicine theory. Research on warming therapy focuses on pharmacology at present. Studying the feature of nerve-body fluid-metabolism-function in cold syndrome is of importance for illustrating the nature of warming therapy and elucidating the function of medication.
