Lysosomal Calcium Channels in Autophagy and Cancer

This is the authors' abstract. We don't add key points for this paper.

Ca2+ is pivotal intracellular messenger that coordinates multiple cell functions such as fertilization, growth, differentiation, and viability. Intracellular Ca2+ signaling is regulated by both extracellular Ca2+ entry and Ca2+ release from intracellular stores. Apart from working as the cellular recycling center, the lysosome has been increasingly recognized as a significant intracellular Ca2+ store that provides Ca2+ to regulate many cellular processes. The lysosome also talks to other organelles by releasing and taking up Ca2+. In lysosomal Ca2+-dependent processes, autophagy is particularly important, because it has been implicated in many human diseases including cancer. This review will discuss the major components of lysosomal Ca2+ stores and their roles in autophagy and human cancer progression.
