Abstract
Autophagy is an intracellular lysosomal degradation process involved in multiple facets of cancer biology. Various dimensions of autophagy are associated with tumor growth and cancer progression, and here we focus on the dimensions involved in regulation of cell survival/cell death, cell proliferation and tumor dormancy. The first dimension of autophagy supports cell survival under stress within tumors and under certain contexts drives cell death, impacting tumor growth. The second dimension of autophagy promotes proliferation through directly regulating cell cycle or indirectly maintaining metabolism, increasing tumor growth. The third dimension of autophagy facilitates tumor cell dormancy, contributing to cancer treatment resistance and cancer recurrence. The intricate relationship between these three dimensions of autophagy influences the extent of tumor growth and cancer progression. In this review, we summarize the roles of the three dimensions of autophagy in tumor growth and cancer progression, and discuss unanswered questions in these fields.
