Abstract
Autophagy is an intracellular degradation system that delivers cytoplasmic constituents to the lysosome. Despite its simplicity, recent progress has demonstrated that autophagy plays a wide variety of physiological and pathophysiological roles, which are sometimes complex. Autophagy consists of several sequential steps--sequestration, transport to lysosomes, degradation, and utilization of degradation products--and each step may exert different function. In this review, the process of autophagy is summarized, and the role of autophagy is discussed in a process-based manner.

MiR-200b regulates autophagy associated with chemoresistance in human lung adenocarcinoma

TL;DR: An inverse correlation between miR-200b and autophagy-associated gene 12 (ATG12) expressions was observed in docetaxel-resistant and sensitive LAD cells as well as in tissue samples, providing new evidence for the mechanisms governing the microRNA (miRNA)- ATG12 network and their possible contribution to Autophagy modulation and LAD chemoresistance.

mTOR Signaling in Autophagy Regulation in the Kidney

TL;DR: The mechanistic/mammalian target of rapamycin, a serine/threonine protein kinase, is a key player in stimulating cellular anabolism in response to nutrients and growth factors, and plays a crucial role in suppressing autophagy activity.

NF-kappaB P50/P65 hetero-dimer mediates differential regulation of CD166/ALCAM expression via interaction with micoRNA-9 after serum deprivation, providing evidence for a novel negative auto-regulatory loop

TL;DR: A novel negative auto-regulatory loop in which NF-κB mediates differential regulation of CD166 after SD is elucidated and it is proposed that miR-9 promotes cell migration largely due to inhibition ofCD166.

p62/SQSTM1 Binds Directly to Atg8/LC3 to Facilitate Degradation of Ubiquitinated Protein Aggregates by Autophagy

TL;DR: It is demonstrated that the previously reported aggresome-like induced structures containing ubiquitinated proteins in cytosolic bodies are dependent on p62 for their formation and p62 is required both for the formation and the degradation of polyubiquitin-containing bodies by autophagy.
