PTEN-induced kinase 1 (PINK1) was identified initially in cancer cells as a gene up-regulated by overexpression of the major tumor suppressor, PTEN. Loss-of-function mutations in PINK1 were discovered subsequently to cause autosomal recessive Parkinson's disease. Substantial work during the past decade has revealed that PINK1 regulates several primary cellular processes of significance in cancer cell biology, including cell survival, stress resistance, mitochondrial homeostasis and the cell cycle. Mechanistically, PINK1 has been shown to interact on a number of levels with the pivotal oncogenic PI3-kinase/Akt/mTOR signalling axis and to control critical mitochondrial and metabolic functions that regulate cancer survival, growth, stress resistance and the cell cycle. A cytoprotective and chemoresistant function for PINK1 has been highlighted by some studies, supporting PINK1 as a target in cancer therapeutics. This article reviews the function of PINK1 in cancer cell biology, with an emphasis on the mechanisms by which PINK1 interacts with PI3-kinase/Akt signalling, mitochondrial homeostasis, and the potential context-dependent pro- and anti-tumorigenic functions of PINK1.
