Advanced glycation end products alter the mA-modified RNA profiles in human dermal fibroblasts.

To explore advanced glycation end products (AGEs)-induced mA modification in fibroblasts and its potential role in photoaging. We studied mA modification in AGEs-bovine serum albumin-treated fibroblasts with mA-mRNA & lncRNA epitranscriptomic microarray and bioinformatics analysis. The mA modification level was also investigated in skin samples. mA methylation microarray analysis revealed mA modification profiles in AGEs-treated fibroblasts. Gene ontology, Kyoto Encyclopedia of Genes and Genomes, protein-protein interaction and competing endogenous RNA network analysis indicated that the genes of differentially methylated mRNAs and lncRNAs were mainly related to inflammation processes. We also found that AGEs-bovine serum albumin dose-dependently increased the mA level and expression in both fibroblasts and sun-exposed skin. Our study provided novel information regarding alterations of mA modifications in AGEs-induced dermal fibroblasts and potential targets for treatment of photoaging.
