Vitamin D Deficiency And Its Role In Pathologies Of Oxidative Stress: A Literature Review, Philippe Dentino, Johanna Mora, Li Zuo

School of Medicine Publications

Vitamin D (VD) is a key mineral providing critical modulation of reduction-oxidation homeostasis within biological systems. VD and the VD receptor coordinate essential cellular activities, including mitochondrial electron transport, respiration, antioxidation, gene regulation, and calcium transportation. Reactive oxygen species (ROS), a natural by-product of cellular metabolism, play a prominent role in the mechanisms of biological antioxidant systems and form the basis of antioxidant therapies. However, ROS may also perpetuate pathological processes when produced in excess secondary to inflammatory pathways. Aging processes within cells rely on this reduction-oxidation homeostasis. Thus, the interaction with VD, its receptor, mitochondria, and oxidative stress forms …

Structural Insights Into Ssna1 Self-Assembly And Its Microtubule Binding For Centriole Maintenance, Lorenzo Agostini, Jason A Pfister, Nirakar Basnet, Jienyu Ding, Rui Zhang, Christian Biertümpfel, Kevin F O'Connell, Naoko Mizuno

2020-Current year OA Pubs

SSNA1 is a fibrillar protein involved in dynamic microtubule remodeling, including nucleation, co-polymerization, and microtubule branching. The underlying molecular mechanism has remained unclear due to a lack of structural information. Here, we determine the cryo-EM structure of C.elegans SSNA-1 at 4.55-Å resolution and evaluate its role in embryonic development. We find that SSNA-1 forms an anti-parallel coiled-coil, with self-assembly facilitated by an overhang of 16 C-terminal residues that form a triple-stranded helical junction. The microtubule-binding region is within the triple-stranded junction, suggesting that self-assembly of SSNA-1 creates hubs for effective microtubule interaction. Genetical analysis elucidates that SSNA-1 deletion significantly reduces …
