Fig. 5. NSUN5 inhibits erastin-induced ferroptosis in bone marrow-derived stem cells (BMSCs) by 5mC modification of FTH1 and FTL RNA.

A, B The results of the dot blot assay showed that NSUN5 knockdown reduced 5mC levels, whereas NSUN5 overexpression elicited the opposite effect. *p < 0.05. C Compared with control cells, 5mC levels were reduced in NSUN5-depleted cells, as determined by immunofluorescence analysis. *p < 0.05. D 5mC antibody enriched FTH1 and FTL mRNA, whereas NSUN5 knockdown reduced 5mC levels in FTH1 and FTL mRNA, as determined by RNA immunoprecipitation (RIP) and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis. *p < 0.05. E Methylation sites of FTH1 and FTL mRNA in control of NSUN5-depleted BMSCs were mainly in the 5′ or 3′ UTR. F, G Bisulfite-sequencing analysis revealed that NSUN5 knockdown abolished the C-to-T conversion at FTH1 and FTL mRNA cytosine methylation sites, *p < 0.05 (D).
