Outline of Final Research Achievements |
Pyrimidine are building blocks of DNA/RNA and essential to sustain life. Human cells obtain pyrimidine bases from either salvage or de novo biosynthesis pathways, which are completely dependent on pyrimidine precursors and oxygen, respectively. Both nutrients are provided by blood and the molecular mechanism of both pathways are well studied. Solid tumors are known to be hypovascularized making the provision of those nutrients extremely low (tumor microenvironment). Since the growth is not affected, those type of cancer cells may obtain pyrimidines by unknown mechanism. The present study aimed to identify the mechanism of pyrimidine acquisition in tumor microenvironment by biochemical, structural biology and reverse chemical biology approaches. As the main result, we have identified a novel mechanism involving mitochondria, which allows the pyrimidines de novo biosynthesis even in the absence of oxygen and can be explored for development of new drugs for cancer chemotherapy.
