Expression and clinical value of serum miR-21 and PBMC Peli1 in autoimmune POI patients

Objective To investigate the expression level and clinical significance of serum miR-21 and Peli1 mRNA in peripheral blood mononuclear cells (PBMC) of patients with autoimmune premature ovarian insufficiency (aPOI). Methods A total of 26 patients untreated and initially diagnosed as autoimmune POI (aPOI group) and 30 healthy young females (control group), visited during April 2018 to October 2019 in Zhujiang Hospital of Southern Medical University, were included in present study. The general data of each subject were recorded. The expression levels of serum miR-21 and PBMC Peli1 mRNA were detected by qRT-PCR, and the serum sex hormone [estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH)], anti-Mullerian hormone (AMH), thyroid hormones and immune-related indicators were evaluated. Uterus and ovary index of all subjects were assessed by ultrasonography. Results The expression levels of serum miR-21 and PBMC Peli1 mRNA were significantly lower in aPOI group than those in control group (
