To test whether m6A modification of Slc15a3 occurred in the macrophages within the IMQ‐induced psoriasis‐like lesion, we sorted out macrophages to perform MeRIP‐qPCR and qRT‐PCR assays and found that the 3’‐UTR region, not 5’‐UTR region or exon 2, was m6A modified and that the modification level was positively correlated to mRNA expression level (Figure 4D; Figure S4B, Supporting Information). Here, SLC15A3 is linked to psoriasis.
