MiR-668-5p targets ZNRF3, an E3 ubiquitin ligase to enhance osteoblast function and alleviate senescence in doxorubicin-induced age-related bone loss.

ABSTRACT:

Introduction

Aging is a complex biological phenomenon that drives the progression of numerous chronic conditions, including osteoporosis, which is characterized by bone loss and increased risk of fragility fractures. The study of microRNA (miRNA) functions has provided valuable insights into the mechanisms that regulate aging and the senescence process. In this study, we identified microRNA 668-5p (miR-668-5p) as a novel regulator of osteoblast function and further elucidated its role in age-related bone loss driven by cellular senescence.

Methods

miR-668-5p function was assessed through mimic transfection in osteoblasts, with osteogenic differentiation evaluated by osteogenic gene and protein expression. Target confirmation was conducted using a dual luciferase 3'UTR report
