Effect of DGAT loss on hypoxic tumor cells growing under serum-deprived conditions


ABSTRACT: The metabolic enzyme diglyceride acyltransferase (DGAT) is responsible for the synthesis of triglycerides. Loss of its expression may sensitize cells to conditions of nutrient and oxygen that are commonly present in tumors. This study is designed to identify stress response pathways that may be induced following the shRNA-mediated knockdown of the two genes coding for the DGAT enzymes. In vitro growth conditions lacking serum and oxygen were used to mimic growth conditions commonly found in poorly perfused tumor domains We used a microarray study to identify global transcriptional changes in kidney cancer cells (A498) grown under serum deprived conditions. DGAT was knocked down using doxycycline, which induced DGAT1/2 shRNA expression. The effects of both DGAT loss and oxygen deprivation on the transcriptome were tested.
