摘　　要：Erythropoiesis is a complex,precise,and lifelong process that is essential for maintaining normal body functions.Its strict regulation is necessary to prevent a variety of blood diseases.Normal erythropoiesis is precisely regulated by an intricate network that involves transcription levels,signal transduction,and various epigenetic modifications.In recent years,research on posttranscriptional levels in erythropoiesis has expanded significantly.The dynamic regulation of splicing transitions is responsible for changes in protein isoform expression that add new functions beneficial for erythropoiesis.RNA-binding proteins adapt the translation of transcripts to the protein requirements of the cell,yielding mRNA with dynamic translation efficiency.Noncoding RNAs,such as microRNAs and lncRNAs,are indispensable for changing the translational efficiency and/or stability of targeted mRNAs to maintain the normal expression of genes related to erythropoiesis.N6-methyladenosine-dependent regulation of mRNA translation plays an important role in maintaining the expression programs of erythroid-related genes and promoting erythroid lineage determination.This review aims to describe our current understanding of the role of post-transcriptional regulation in erythropoiesis and erythroid-associated diseases,and to shed light on the physiological and pathological implications of the post-transcriptional regulation machinery in erythropoiesis.These may help to further enrich our understanding of the regulatory network of erythropoiesis and provide new strategies for the diagnosis and treatment of erythroid-related diseases.
