Urolithin A improves Alzheimer's disease cognition and restores mitophagy and lysosomal functions
Background Compromised autophagy, including impaired mitophagy and lysosomal function, is thought to play a pivotal role in Alzheimer’s disease (AD). Urolithin A (UA) is a gut microbial metabolite of ellagic acid that stimulates mitophagy. The effects of

Mitophagy and heart failure [PDF]
Cardiac mitochondria are responsible for generating energy in the form of ATP through oxidative phosphorylation and are crucial for cardiac function. Mitochondrial dysfunction is a major contributor to loss of myocytes and development of heart failure.

Mitophagy in metabolic syndrome
AbstractMetabolic syndrome (MS), a chronic and non‐communicable pathological condition, is characterized by a constellation of clinical manifestations including insulin resistance, abdominal adiposity, elevated blood pressure, and perturbations in lipid metabolism.

Autophagosome marker, LC3, is released extracellularly via several distinct pathways
This study establishes a novel HiBiT‐tagging system for ultrasensitive detection of LC3, revealing multiple pathways for its extracellular secretion. It demonstrates that LC3 is released via both autophagy‐dependent and ‐independent mechanisms, including a novel route for nonlipidated LC3‐I.

Insulin-Like Growth Factor I Prevents Cellular Aging via Activation of Mitophagy
Mitochondrial dysfunction is a hallmark of cellular aging. Mitophagy is a critical mitochondrial quality control mechanism that removes dysfunctional mitochondria and contributes to cell survival. Insulin-like growth factor 1 (IGF-1) promotes survival of

Parkin uses the UPS to ship off dysfunctional mitochondria [PDF]
Parkin is a ubiquitin E3 ligase that is implicated in familial Parkinson disease (PD). Previous studies have established its role in mitophagy, a pathway whereby dysfunctional mitochondria are targeted for autophagic degradation.

The selectivity and specificity of autophagy in drosophila [PDF]
Autophagy is a process of cellular self-degradation and is a major pathway for elimination of cytoplasmic material by the lysosomes. Autophagy is responsible for the degradation of damaged organelles and protein aggregates and therefore plays a ...

Measuring In Vivo Mitophagy [PDF]
Alterations in mitophagy have been increasingly linked to aging and age-related diseases. There are, however, no convenient methods to analyze mitophagy in vivo. Here, we describe a transgenic mouse model in which we expressed a mitochondrial-targeted form of the fluorescent reporter Keima (mt-Keima). Keima is a coral-derived protein that exhibits both

SIRT4 positively regulates autophagy via ULK1, but independently of HDAC6 and OPA1
Cells expressing SIRT4 (H161Y), a catalytically inactive mutant of the sirtuin SIRT4, fail to upregulate LC3B‐II and exhibit a reduced autophagic flux under stress conditions. Interestingly, SIRT4(H161Y) promotes phosphorylation of ULK1 at S638 and S758 that are associated with inhibition of autophagy initiation.
