Autophagosome formation is required for cardioprotection by chloramphenicol [PDF]
Life Sciences, 2017 Chloramphenicol (CAP), a broad spectrum antibiotic, was shown to protect the heart against ischemia/reperfusion (I/R) injury. CAP also induces autophagy, however, it is not known whether CAP-induced cardioprotection is mediated by autophagy. Therefore, here we aimed to assess whether activation of autophagy is required for the infarct size limiting ...

Regulation of actin nucleation and autophagosome formation [PDF]
Cellular and Molecular Life Sciences, 2016 Autophagy is a process of self-eating, whereby cytosolic constituents are enclosed by a double-membrane vesicle before delivery to the lysosome for degradation. This is an important process which allows for recycling of nutrients and cellular components and thus plays a critical role in normal cellular homeostasis as well as cell survival during ...

Atg41/Icy2 regulates autophagosome formation [PDF]
Autophagy, 2015 Macroautophagy (hereafter autophagy) is one of the major degradation systems in eukaryotic cells, and its dysfunction may result in diseases ranging from neurodegeneration to cancer. Although most of the autophagy-related (Atg) proteins that function in this pathway were first identified in yeast, many were subsequently shown to have homologs in higher

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

The N-terminal region of the human autophagy protein ATG16L1 contains a domain that folds into a helical structure consistent with formation of a coiled-coil. [PDF]
PLoS ONE, 2013 Autophagy is a fundamental cellular process required for organelle degradation and removal of invasive pathogens. Autophagosome formation involves the recruitment of, and interaction between, multiple proteins produced from autophagy-related (ATG) genes.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization
Molecular Oncology, EarlyView.In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Dissecting autophagosome formation: The missing pieces [PDF]
Autophagy, 2008 The formation of autophagosomes is the central part of the macroautophagy pathway. Little is known, however, about how the participants in this process affect the membrane dynamics at the phagophore assembly site (PAS). Recently, we demonstrated that Atg8, a lipid-conjugated ubiquitin-like protein, controls the expansion of the phagophore. In addition,

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy
FEBS Open Bio, EarlyView.This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...
