Mitochondrial NUDIX hydrolases: A metabolic link between NAD catabolism, GTP and mitochondrial dynamics
&NA; NAD+ catabolism and mitochondrial dynamics are important parts of normal mitochondrial function and are both reported to be disrupted in aging, neurodegenerative diseases, and acute brain… Expand

CD38 Knockout Mice Show Significant Protection Against Ischemic Brain Damage Despite High Level Poly-ADP-Ribosylation
Several enzymes in cellular bioenergetics metabolism require NAD+ as an essential cofactor for their activity. NAD+ depletion following ischemic insult can result in cell death and has been… Expand

NAD+ precursor modulates post-ischemic mitochondrial fragmentation and reactive oxygen species generation via SIRT3 dependent mechanisms
Global cerebral ischemia depletes brain tissue NAD+, an essential cofactor for mitochondrial and cellular metabolism, leading to bioenergetics failure and cell death. The post-ischemic NAD+ levels… Expand

Significance of Mitochondrial Protein Post-translational Modifications in Pathophysiology of Brain Injury
Mitochondria are complex organelles that undergo constant fusion and fission in order to adapt to the ever-changing cellular environment. The fusion/fission proteins, localized in the inner and outer… Expand

The diversity and relationship of prion protein self-replicating states.
It has become evident that the prion protein (PrP) can form a diverse range of self-replicating structures in addition to bona fide PrP(Sc) or strain-specific PrP(Sc) variants. Some self-replicating… Expand

Multi-targeted Effect of Nicotinamide Mononucleotide on Brain Bioenergetic Metabolism
Dysfunctions in NAD+ metabolism are associated with neurodegenerative diseases, acute brain injury, diabetes, and aging. Loss of NAD+ levels results in impairment of mitochondria function, which… Expand

Nicotinamide mononucleotide alters mitochondrial dynamics by SIRT3‐dependent mechanism in male mice
Nicotinamide adenine dinucleotide (NAD+) is a central signaling molecule and enzyme cofactor that is involved in a variety of fundamental biological processes. NAD+ levels decline with age,… Expand

Loss of Cellular Sialidases Does Not Affect the Sialylation Status of the Prion Protein but Increases the Amounts of Its Proteolytic Fragment C1
The central molecular event underlying prion diseases involves conformational change of the cellular form of the prion protein (PrPC), which is a sialoglycoprotein, into the disease-associated,… Expand

Sialylation of Glycosylphosphatidylinositol (GPI) Anchors of Mammalian Prions Is Regulated in a Host-, Tissue-, and Cell-specific Manner*
Prions or PrPSc are proteinaceous infectious agents that consist of misfolded, self-replicating states of the prion protein or PrPC. PrPC is posttranslationally modified with N-linked glycans and a… Expand
