PCYT2 and type 2 diabetes mellitus: To further confirm the effect of PCYT2 on liver metabolites in T2DM, we tested the lipids of control L02 cells (C), HG&FFA-stimulated L02 cells (H), HG&FFA-stimulated L02 cells with 100 μM CDP-etn (ZL), L02 cells overexpressing PCYT2 (LV), and L02 cells overexpressing PCYT2 under HG&FFA stimulation (LH).
