ALONSO REMEDIOS, Alain; PEREZ CUTINO, Maité; VIDAL PEREZ, Zoraida  e  VIDAL PEREZ, Aniuska. Role of Metabolic Reprogramming in Carcinogenesis. ccm [online]. 2016, vol.20, n.2, pp.292-304. ISSN 1560-4381.

The role of the genes that suppress tumors and oncogenes in cellular cycle control is known but its effect in tumoral metabolism is a novel topic in the modern oncology. Nowadays the concept of metabolic reprograming in tumors has been reexamined as an important process related to carcinogenesis. A literature review was done in PubMed database by using descriptors such as genes, suppressor and metabolism; oncogenes and metabolism; neoplasms and metabolism. Oncogenes mutations of code for PI3K, AKT, mTORC and Myc induce an increase of the expression of isoenzimes of the glycolytic path, while they inhibit oxidative phosphorylation. This makes possible anabolic metabolism. They are also related to an increase in glucose consumption rates and the release of lactase to the tumoral microenvironment. The importance of anabolic metabolism in cancer progression has been proved in tumor cells, which is another option in the treatment of the disease.
