A nonstructural protein encoded by a rice reovirus induces an incomplete autophagy to promote viral spread in insect vectors.

PLoS Pathogens, 2022
Viruses can hijack autophagosomes as the nonlytic release vehicles in cultured host cells. However, how autophagosome-mediated viral spread occurs in infected host tissues or organs in vivo remains poorly understood.

HUNK Phosphorylates Rubicon to Support Autophagy [PDF]

, 2019
Background: Autophagy is a catabolic cellular recycling pathway that is essential for maintaining intracellular homeostasis. Autophagosome formation is achieved via the coordination of the Beclin-1 protein complex.

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,

Autophagosome Formation in Mammalian Cells.

Cell Structure and Function, 2002
Macroautophagy is an intracellular degradation system for the majority of proteins and some organelles. The molecular mechanism of autophagy has been extensively studied using the yeast, Saccharomyces cerevisiae, during these past 10 years. These studies suggested that the molecular machinery of autophagosome formation is well conserved from yeast to ...

Lipid storage and autophagy in melanoma cancer cells [PDF]

, 2017
Cancer stem cells (CSC) represent a key cellular subpopulation controlling biological features such as cancer progression in all cancer types. By using melanospheres established from human melanoma patients, we compared less differentiated melanosphere ...

Arabidopsis NAP1 Regulates the Formation of Autophagosomes [PDF]

Current Biology, 2016
The SCAR/WAVE complex is required for ARP2/3-mediated actin nucleation, and these complexes are highly conserved in plants and animals [1, 2]. Proteins from the SCAR/WAVE complex have been found to be membrane associated in plants [3]. Using fluorescent protein fusions, we have found that NAP1 [4], a component of the SCAR/WAVE complex, locates to ...

LC3 and STRAP regulate actin filament assembly by JMY during autophagosome formation. [PDF]

, 2019
During autophagy, actin filament networks move and remodel cellular membranes to form autophagosomes that enclose and metabolize cytoplasmic contents. Two actin regulators, WHAMM and JMY, participate in autophagosome formation, but the signals linking ...

Dexmedetomidine alleviates CoCl-induced hypoxic cellular damage in INS-1 cells by regulating autophagy [PDF]

Korean Journal of Anesthesiology
Background Ischemia-reperfusion (I/R) injury is inevitable during the perioperative period. The pancreas is susceptible to I/R injury. Autophagy, a self-digestion process, is upregulated during I/R injury and strongly induced by hypoxia.

TMEM41B functions with VMP1 in autophagosome formation [PDF]

Autophagy, 2019
Macroautophagy/autophagy requires many autophagy-related (ATG) proteins. Most of the ATG genes were identified by genetic screening using simple model organisms. Recently, we performed a forward genetic screen in mammalian cells using the CRISPR-Cas9 system and our autophagic flux reporter GFP-LC3-RFP.

Pharmacological activation of SIRT6 triggers lethal autophagy in human cancer cells [PDF]

, 2018
Sirtuin 6 (SIRT6) is a member of the NAD+-dependent class III deacetylase sirtuin family, which plays a key role in cancer by controlling transcription, genome stability, telomere integrity, DNA repair, and autophagy.
