Abstract

Mitochondria determine the physiological status of most eukaryotes. Mitochondrial dynamics plays an important role in maintaining mitochondrial homeostasis, and the disorder in mitochondrial dynamics could affect cellular energy metabolism leading to tumorigenesis. In recent years, disrupted mitochondrial dynamics has been found to influence the biological behaviors of gastrointestinal cancer with the potential to be a novel target for its individualized therapy. This review systematically introduced the role of mitochondrial dynamics in maintaining mitochondrial homeostasis, and further elaborated the effects of disrupted mitochondrial dynamics on the cellular biological behaviors of gastrointestinal cancer as well as its association with cancer progression. We aim to provide clues for elucidating the etiology and pathogenesis of gastrointestinal cancer from the perspective of mitochondrial homeostasis and disorder.

Keywords: Fission; Fusion; Gastrointestinal cancer; Mitochondria; Mitochondrial biogenesis; Mitochondrial dynamic; Mitochondrial homeostasis; Mitochondrial quality control; Mitophagy.

Mitochondrial homeostasis is maintained by MQC system. Mitochondrial quality control system is composed of the balance between fusion (A) and fission (B), and between biogenesis (C) and mitophagy (D). A. Fusion. Mitochondria mediate fusion of IMM and OMM through OPA1 and MFN1/2. B. Fission. Mitochondria complete fission through fission-related factors such as DRP1 and dynein. C. Mitochondrial biogenesis. AMPK and SIRT1 pathways activate the PGC-1α/NRF1/2/TAFM axis and affect mitochondrial biogenesis. D. Mitophagy. Mitochondrial mitophagy is initiated to eliminate damaged mitochondria generated from disrupted fission and fusion

Disorder in mitochondrial dynamics and gastrointestinal cancer. Disrupted mitochondrial dynamics promotes the cancerization of gastrointestinal cellular biological behaviors, thus participating in the occurrence, development and prognosis of gastrointestinal tumor
