PHTF2 and gastric cancer: Not only because PHTF2 was involved in regulating ACSL1 expression in GCIY and NUGC3 cells (Figure 3C), but because ACSL1 was a key factor in lipid biosynthesis and fatty acid degradation in tumors, whose expression was also confirmed to be significantly correlated with the expression pattern of PHTF2 in gastric cancer (Figure 2G).
