A Review of Mitochondrial Biogenesis and Cellular Response

Mitochondrial biogenesis is a complex process involving the coordinated expression of mitochondrial and nuclear genes, the import of the products of the latter into the organelle and turnover of this process. Mitochondrial malfunction or defects in any of the many pathways involved in mitochondrial biogenesis can lead to degenerative diseases and possibly play an important part in aging. Because of the mitochondrial relationship with some factors such as matrix proteins, cell cycle and evolution, in this review article we examined the mitochondrial relationship with these factors and mechanisms. The data were extracted from NCBI and SID databases. Changes and mutations in mitochondria are common in most of the molecular processes and important diseases including cancer, but these mutations do not result in mitochondria deactivation. Investigating these pathways helps us to identify and treat diseases such as cancer.
The mitochondria is the most important source of cellular energy supply, and mitochondrial damage can interfere with cellular activity and reduce the amount of energy produced and increase the production of free radicals. Mitochondria biogenesis is one of the protective methods of the cell against oxidative stress, which has a cell protective role.
