We used RNA-sequencing (RNA-Seq) technology and an old hematopoietic stem and progenitor cells (HSPCs) model in vitro to analyze differential expressions of mismatch repair (MMR)-related genes in aged HSPCs, so as to explore the mechanism of DNA MMR injury inhematopoietic stem cells (HSC) aging. In this study, by combining RNA-seq data and National Center for Biotechnology Information database, we focus on six widely reported MMR genes MSH2, MSH3, MSH6, MLH1, PMS1, PMS2, and five MMR genes with closer ties to HSC aging Pcna, Exo1, Rpa1, Rpa2, and Rpa3 according to the genes functional classification and the related signaling pathway. It is concluded that MMR is closely related to HSC aging. This study provides experimental evidence for future researching MMR in HSC aging.
