An effector of the Irish potato famine pathogen antagonizes a host autophagy cargo receptor [PDF]

, 2016
Plants use autophagy to safeguard against infectious diseases. However, how plant pathogens interfere with autophagy-related processes is unknown. Here, we show that PexRD54, an effector from the Irish potato famine pathogen Phytophthora infestans, binds

Calpain as a Novel Regulator of Autophagosome Formation [PDF]

Autophagy, 2007
Ubiquitously expressed micro- and m-calpain proteases consist of 80-kDa catalytic subunits encoded by the Capn1 and Capn2 genes, respectively, and a common 28-kDa regulatory subunit encoded by the calpain small 1 (Capns1) gene. The micro- and m-calpain proteases have been implicated in both pro- or anti-apoptotic functions.

ATG4B is required for mTORC1‐mediated anabolic activity and is associated with clinical outcomes in non‐small cell lung cancer

FEBS Open Bio, EarlyView.
The relationship between anabolic and catabolic processes governing lung cancer cell growth is nuanced. We show that ATG4B, an autophagy regulator, is elevated in lung cancer and that high ATG4B is associated with worse patient outcomes. Targeting ATG4B in cells reduces growth, protein synthesis, and mTORC1 activity, demonstrating a new relationship ...

Involvement of ACSL3 in the formation of autophagosomes and lipid droplets during starvation conditions

Autophagy Reports
Acyl-CoA synthetase long-chain (ACSL) catalyzes the conversion of fatty acids into acyl-CoA, which is used for neutral lipid and phospholipid synthesis.

Autophagy processes are dependent on EGF receptor signaling [PDF]

, 2018
Autophagy is a not well-understood conserved mechanism activated during nutritional deprivation in order to maintain cellular homeostasis. In the present study, we investigated the correlations between autophagy, apoptosis and the MAPK pathways in ...

Autophagosome marker, LC3, is released extracellularly via several distinct pathways

FEBS Open Bio, EarlyView.
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.

Autophagosome formation is initiated at phosphatidylinositol synthase‐enriched ER subdomains [PDF]

, 2017
The autophagosome, a double‐membrane structure mediating degradation of cytoplasmic materials by macroautophagy, is formed in close proximity to the endoplasmic reticulum (ER). However, how the ER membrane is involved in autophagy initiation and to which

SIRT4 positively regulates autophagy via ULK1, but independently of HDAC6 and OPA1

FEBS Open Bio, EarlyView.
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.

Palmitoylation of ULK1 by ZDHHC13 plays a crucial role in autophagy

Nature Communications
Autophagy is a highly conserved process from yeast to mammals in which intracellular materials are engulfed by a double-membrane organelle called autophagosome and degrading materials by fusing with the lysosome.

PlAtg8-mediated autophagy regulates vegetative growth, sporangial cleavage, and pathogenesis in Peronophythora litchii

Microbiology Spectrum
Autophagy is a conserved cellular metabolic process in eukaryotes that transports damaged or redundant intracellular organelles and proteins to lysosomes or vacuoles for degradation and recycling.
