Oncogenic human herpesvirus hijacks proline metabolism for tumorigenesis

Abstract excerpt

Significance While understanding metabolic change of tumor cells is crucial to improve cancer therapy, current 2D cell culture condition may not fully recapitulate in vivo metabolic environment of tumors. Our metabolomics analysis demonstrates that proline metabolism is critical for the KSHV-transformed cell growth in 3D culture, not in 2D culture. Specifically, the KSHV K1 oncoprotein activates PYCR proline...
