The Proteasomal Deubiquitinating Enzyme PSMD14 Regulates Macroautophagy by Controlling Golgi-to-ER Retrograde Transport [PDF]
, 2020 Ubiquitination regulates several biological processes, however the role of specific members of the ubiquitinome on intracellular membrane trafficking is not yet fully understood.

The EmERgence of Autophagosomes [PDF]
Developmental Cell, 2009 Autophagosomes are large double-membrane vesicles that enclose cytoplasmic components targeting them for degradation. Two recent reports reveal that phagophores, the autophagosome precursors, are surrounded by and connected to rough endoplasmic reticulum (ER) membranes.

Distinct roles in autophagy and importance in infectivity of the two ATG4 cysteine peptidases of leishmania major [PDF]
, 2012 Macroautophagy in Leishmania, which is important for the cellular remodeling required during differentiation, relies upon the hydrolytic activity of two ATG4 cysteine peptidases (ATG4.1 and ATG4.2).

miR-4463 Regulates Hypoxia-Induced Autophagy and Apoptosis by Targeting ULK1 in Endothelial Cells
Frontiers in Bioscience-Landmark, 2022 Background: Our previous study revealed aberrant miR-4463 expression in the vascular tissues of patients with arteriosclerosis obliterans of the lower extremities (ASO), but the role of miR-4463 was largely ambiguous.

ATPase-regulated autophagosome biogenesis
Autophagy, 2023 Omega-shaped domains of the endoplasmic reticulum, known as omegasomes, have been suggested to contribute to autophagosome biogenesis, although their exact function is not known. Omegasomes are characterized by the presence of the double FYVE domain containing protein ZFYVE1/DFCP1, but it has remained a paradox that depletion of ZFYVE1 does not prevent

Frontiers in Cellular and Infection Microbiology, 2022 Cystic fibrosis (CF) human and mouse macrophages are defective in their ability to clear bacteria such as Burkholderia cenocepacia. The autophagy process in CF (F508del) macrophages is halted, and the underlying mechanism remains unclear.

Tracking autophagy during proliferation and differentiation of trypanosoma brucei [PDF]
, 2014 Autophagy is a lysosome-dependent degradation mechanism that sequesters target cargo into autophagosomal vesicles. The Trypanosoma brucei genome contains apparent orthologues of several autophagy-related proteins including an ATG8 family. These ubiquitin-

Antioxidants, 2023 Autophagy is a fundamental homeostatic process in which certain cellular components are ingested by double-membrane autophagosomes and then degraded to create energy or to maintain cellular homeostasis and survival.

VCP-dependent muscle degeneration is linked to defects in a dynamic tubular lysosomal network in vivo. [PDF]
, 2015 Lysosomes are classically viewed as vesicular structures to which cargos are delivered for degradation. Here, we identify a network of dynamic, tubular lysosomes that extends throughout Drosophila muscle, in vivo. Live imaging reveals that autophagosomes
