TLDR Apoptosis, not oxidative stress, is linked to aging in mice with mtDNA mutations.
The document summarized various scientific studies from 2005, covering advancements in multiple fields. Notably, Prolla et al. linked apoptosis, rather than oxidative stress, to aging in a mouse model with increased mtDNA mutations, which exhibited symptoms like hair loss. Other studies included the development of in vivo photo-cross-linking for protein interaction studies in E. coli, the formation of distinct heterodimers by β1- and β2-adrenergic receptors in cardiomyocytes, and a confocal imaging technique for quantifying free Ca2+ in organelles. Additionally, research on sildenafil citrate suggested a new treatment pathway for nephrogenic diabetes insipidus, while studies on Akt1 and synaptic transmission provided insights into cardiac function and synaptic interactions, respectively.
