Analysis of glycerophospholipid metabolism showed that PG (16:0_20:2) was significantly and positively correlated with glycerophospholipid synthesis-related genes PCYT1A, PGS1 and LPIN1, suggesting that this metabolite plays an important role in regulating lipid metabolism disorders induced by Cd exposure (Figure 6B). This evidence concerns the gene PCYT1A and Disorder of lipid metabolism.
