NF ‑κB/IκBα signaling pathways are essential for resistance to heat stress‑induced ROS production in pulmonary microvascular endothelial cells
Mol Med Rep. 2021 Nov;24(5):814. doi: 10.3892/mmr.2021.12454. Epub 2021 Sep 24.ABSTRACTThe results of a previous study demonstrated that heat stress (HS) triggered oxidative stress, which in turn induced the apoptosis of epithelial cells. These results uncovered a novel mechanism underlying the activation of NF‑κB in primary human umbilical vein endothelial cells. The present study aimed to further investigate the role of NF‑κB/IκBα signaling pathways in the inhibition of HS‑induced reactive oxygen species (ROS) generation and cytotoxicity in endothelial cells. The results of the present study demonstrated that H...

Metabolomic profiling identifies a novel mechanism for heat stroke ‑related acute kidney injury
Mol Med Rep. 2021 Apr;23(4):1. doi: 10.3892/mmr.2021.11880. Epub 2021 Jan 28.ABSTRACTHeat stroke can induce a systemic inflammatory response, which may lead to multi‑organ dysfunction including acute kidney injury (AKI) and electrolyte disturbances. To investigate the pathogenesis of heat stroke (HS)‑related AKI, a mouse model of HS was induced by increasing the animal's core temperature to 41˚C. Blood samples obtained from the tail vein were used to measure plasma glucose and creatinine levels. Micro‑positron emission tomography‑computed tomography (micro‑PET/CT), H&E staining and transmission electron ...
