Background Androgenetic alopecia (AGA), the most prevalent form of hair loss, is driven by the dysfunction of dermal papilla cells (DPCs). Emerging evidence implicates DPC senescence in the pathogenesis of AGA; however, the underlying molecular mechanisms remain incompletely elucidated.
<...Aortic disease poses a significant mortality risk in adults, yet many of its underlying factors remain undiscovered. In this study, we identify mitochondrial NAD⁺ deficiency as a causal factor. Metabolomics analysis of 73 surgical aortic specimens revealed impaired NAD⁺ salvage and mitochondrial ...
Oxidative phosphorylation (OXPHOS) fulfills energy metabolism and biosynthesis through tricarboxylic acid (TCA) cycle and an intact electron transport chain (ETC). Mitochondrial glutamine import (MGI) replenishes TCA cycle through glutaminolysis, but its broader roles in cancer remains unclear. H...

The vasculature represents a highly plastic compartment, capable of switching from a quiescent to an active proliferative state during angiogenesis. Metabolic reprogramming in endothelial cells (ECs) thereby is crucial to cover the increasing cellular energy demand under growth conditions. Here w...
