Assessing Autophagy in the Leydig Cells

Methods in Molecular Biology

Abstract

Autophagy is an important intracellular degradation system which is implicated in many physiological and pathological processes. During autophagy, cytosolic constituents such as organelles and macromolecules are engulfed by autophagosome, and then they fuse with lysosomes for degradation and recycle of the engulfed components within the autolysosome to maintain cellular homeostasis. In male testis, the Leydig cells provide the major source of testosterone production. Autophagy is extremely active in Leydig cells and is involved in the steroid production. However, the precise role of autophagy in Leydig cells is still largely unknown. Thus, a comprehensive measurement of autophagic activity with different methods would shed light on our knowledge about the functional role of autophagy in regulating male reproductive physiology. In this chapter, we describe the morphological, cellular, and biochemical methods to monitor autophagy in Leydig cells.

ATG proteins

The discovery of autophagy-related ('ATG') proteins in the 1990s greatly advanced the mechanistic understanding of autophagy and clarified the fact that autophagy serves important roles in various biological processes.

Autophagosome

An autophagosome is the formation of double-membrane vesicles that involve numerous proteins and cytoplasmic components. These double-membrane vesicles are then terminated at the lysosome where they are degraded. Discover the latest research on autophagosomes here.
