Mechanisms of autophagosome formation
Proceedings of the Japan Academy, Series BThe formation of autophagosomes is a pivotal step in autophagy, a lysosomal degradation system that plays a crucial role in maintaining cellular homeostasis. After autophagy induction, phase separation of the autophagy-related (Atg) 1 complex occurs, facilitating the gathering of Atg proteins and organizes the autophagosome formation site, where the ...

Vesicular trafficking and autophagosome formation [PDF]
Cell Death & Differentiation, 2009 The source of the autophagosome membrane, and the formation of the autophagosome remain the most important questions for understanding autophagy. Fundamentally, the process of autophagosome formation is similar between yeast and mammalian cells and many of the proteins involved (called the autophagy-related (Atg) proteins) are known, having been first ...

Advanced Science, EarlyView.Phosphorylation of Optineurin by TBK1 induces the formation of filaments that condensate upon binding to linear polyubiquitin. Membrane‐anchored LC3 partitions into these condensates, suggesting that phase separation of filamentous Optineurin with ubiquitylated cargo promotes the sequestration of cargo and its subsequent alignment with LC3‐positive ...

Inhibitory effect of mTOR activator MHY1485 on autophagy: suppression of lysosomal fusion. [PDF]
PLoS ONE, 2012 Autophagy is a major degradative process responsible for the disposal of cytoplasmic proteins and dysfunctional organelles via the lysosomal pathway. During the autophagic process, cells form double-membraned vesicles called autophagosomes that sequester

Alkyltriphenylphosphonium Binding to Cardiolipin Triggers Oncosis in Cancer Cells
Advanced Science, EarlyView.Alkyltriphenylphosphonium, exemplified by TPP+‐C14, preferentially accumulates in mitochondria and selectively binds to cardiolipin, a key phospholipid of the inner mitochondrial membrane, causing loss of mitochondrial membrane potential, severe cellular ATP depletion, and calcium imbalance.

Biology Open, 2016 Autophagy is an evolutionarily conserved process used for removing surplus and damaged proteins and organelles from the cytoplasm. The unwanted material is incorporated into autophagosomes that eventually fuse with lysosomes, leading to the degradation ...

Proteomic profiling of autophagosome cargo in Saccharomyces cerevisiae. [PDF]
PLoS ONE, 2014 Macroautophagy (autophagy) is a bulk protein-degradation system ubiquitously conserved in eukaryotic cells. During autophagy, cytoplasmic components are enclosed in a membrane compartment, called an autophagosome. The autophagosome fuses with the vacuole/

Human cachexia induces changes in mitochondria, autophagy and apoptosis in the skeletal muscle [PDF]
, 2019 Cachexia is a wasting syndrome characterized by the continuous loss of skeletal muscle mass due to imbalance between protein synthesis and degradation, which is related with poor prognosis and compromised quality of life.

Viruses and arrested autophagosome development [PDF]
Autophagy, 2009 Autophagy is acknowledged as an important cellular defense mechanism against intracellular pathogens. As with other innate immune responses, pathogens have adapted to evade autophagy and in some cases, subvert the pathway to promote their own replication.
