The Role of Mitochondria in Cancer Induction, Progression and Changes in Metabolism

[ Vol. 16 , Issue. 7 ]

Mitochondria play important roles as energetic centers. Mutations in mitochondrial DNA (mtDNA) were found in several diseases, including cancers. Studies on cytoplasmic hybrids (cybrids) confirm that directed mutation introduced into mtDNA could be a reason for cancer induction. Mitochondria could also be a factor linking cancer transformation and progression. The importance of mitochondria in cancer also confirms their involvement in the resistance to treatment. Resistance to treatment of cancer cells can frequently be a reason for glycolysis acceleration. It could be explained by cancer cells’ high proliferation index and high energy request. The involvement of mitochondria in metabolic disturbances of several metabolic diseases, including cancers, was reported. These data confirm that cancer induction, as well as cancer progression, could have metabolic roots. The aberrant products observed in prostate cells involved in the Krebs cycle could promote cancer progression. These multiple relationships between alterations on a genetic level translated into disturbances in cellular metabolism and their potential relation with epigenetic control of gene expression make cancerogenesis more complicated and prognoses’ success in studies on cancer etiology more distant in time.
