Hsa_circ_0004276 inhibits osteogenic differentiation of bone marrow mesenchymal stem cells and exacerbates postmenopausal osteoporosis through interaction with ELAVL1.

ABSTRACT:

Objective

The aim of this study was to investigate the potential of hsa_circ_0004276 as a diagnostic marker for Postmenopausal Osteoporosis (PMO) and its potential interaction with the RNA-binding protein ELAV-like RNA binding protein-1 (ELAVL1).

Methods

The circRNA expression profiles obtained from the GSE159121 dataset were used to screen for differentially expressed circRNAs in patients with PMO. hsa_circ_0004276 was further analyzed and validated for its circular structure using a bioinformatics website, actinomycin D, and RNase R assays. Serum samples from 115 PMO patients and 103 healthy controls were collected. RT-qPCR and western blot were applied to assess hsa_circ_0004276 and ELAVL1. The effects of hsa_circ_0004276 and ELAVL1 on osteogenic differentiation of human
