Nutrient Regulation of Cancer Cell Growth
SUMMARY Renal cell cancer (RCC) is the most common type of kidney cancer, and despite therapeutic advances, mortality remains high. While there are over a dozen RCC subtypes with different genomic drivers, metabolic reprogramming is a shared feature of tumorigenesis and progression across most of the major forms of kidney cancer and represents a targetable vulnerability in RCC. Our preliminary results show that RCCs and other cancers rely on the amino acid asparagine for tumor mTORC1 activity and growth, and methods to deplete tumor asparagine levels impair cancer cell proliferation and block cancer growth. Cancers acquire asparagine through two main routes: 1) consumption from the…
