Oxidative Stress Aggravates Apoptosis of Nucleus Pulposus Cells through m6A Modification of MAT2A Pre-mRNA by METTL16

Figure 2

MAT2A was downregulated while METTL16 was upregulated when human nucleus pulposus cell was under oxidative stress. Human NPCs were exposed to TBHP (100 μm, 4 hours). (a) NPC identification by characterization of their cell surface marker CD24 (b) The expression of MAT2A mRNA was detected by qRT-PCR. (c) The expression of METTL16 mRNA was detected by qRT-PCR. (d) Western blotting for the expression of MAT2A and METTL16 proteins. (e) Immunofluorescence assay for the expression of MAT2A and METTL16 proteins. (f) SAM concentration in the cell culture medium supernatant was detected by ELISA. replicates per group, , , .
