Interaction of MicroRNAs and Endoplasmic Reticulum StressSignaling Pathways / 中国生物化学与分子生物学报

ABSTRACT

Endoplasmic reticulum stress (ERS) is a cellular defensive response to restore homeostasisand reduce the protein load. Over-activation of ERS can induce cell differentiation, proliferation, apoptosis, and autophagy. MicroRNAs (miRNAs) are endogenous non-coding RNAs (ncRNAs) thatregulate the expression of key proteins and genes in the ERS signaling pathway through post-transcriptional action. Meanwhile, activated ERS signaling pathway can indirectly regulate the expressionand function of target genes by decreasing miRNA stability. Based on a brief introduction of ERS classicalsignaling pathways, this paper further elaborated how microRNAs regulate ERS signaling pathways topromote apoptosis and proliferation, and what effect they would have on the expression profile of diseasesbased on this association. We also summarize the regulation of ERS on miRNAs expression and thecurrent research status. The mutual regulation between the two could provide a new idea for the follow-upresearch on the therapeutic targets of diseases.
