Abstract

Mitochondrial dysfunction and significant changes in metabolic pathways accompany cancer development and are responsible for maintaining the tumor microenvironment. Normal mitochondria can trigger intrinsic apoptosis by releasing cytochrome c into the cytosol. The survival of malignant cells highly depends on the suppression of this function. We validated that A250, a highly purified fraction of fermented wheat germ extract (FWGE), increases the carbon flux into the mitochondria, the expression of key elements of the Krebs cycle and oxidative phosphorylation (OXPHOS). The increased respiratory chain activity is related to the mitochondria's ability to release cytochrome c into the cytosol, which triggers the apoptotic cascade. The 68% tumor growth inhibitory effect observed in the murine melanoma study is related to this effect, as proteomic analysis validated similar changes in mitochondrial protein levels in the isolated tumor tissue samples. Blood count data indicated that this effect was not accompanied by general toxicity. This study is significant, as it shows that a highly concentrated form of FWGE is an effective agent that increases normal mitochondrial functionality. The lack of hepatotoxic and general toxic effects makes A250 an excellent candidate targeting mitochondria function in cancer therapy.
