Abstract:
The balance between cell survival and cell death is often lost in human pathologies such as inflammation and cancer. Autophagy plays a critical role in cell survival: essential nutrients are generated by autophagy-dependent degradation and recycling of cellular garbage. On the other hand, cell death is induced by different programs, such as apoptosis, pyroptosis, and necroptosis. Emerging evidence is revealing how cell survival and cell death pathways are coordinated to determine cell fate. For instance, posttranslational modification of proteins with ubiquitin regulates many steps of autophagy and cell death pathways. In this review article, we will discuss how the ubiquitin system influences cell death and autophagy.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....
