Fig. 3. circHECTD1 enhances glutaminolysis in GC.
a The levels of glutamine, glutamate, and α-KG were examined in circHECTD1-silenced BGC823 cells. b The levels of glutamine, glutamate, and α-KG were examined in circHECTD1-overexpressing SGC7901 cells. c Western blotting was performed to detect the expression levels of ASCT2 and GLS1 in circHECTD1-silenced BGC823 cells. d Western blotting was performed to detect the expression levels of ASCT2 and GLS1 in circHECTD1-overexpressing SGC7901 cells. The data are shown as the mean ± SEM, n = 3. **P < 0.01, ***P < 0.001 vs. NC
