Circulating microRNA let‑7e is decreased in knee osteoarthritis, accompanied by elevated apoptosis and reduced autophagy.

ABSTRACT: Knee osteoarthritis (KOA) is a major cause of leg disability in the elderly population. Recently, the expression levels of circulating microRNA (miRNA) let‑7e have been reported to be significantly reduced in KOA. The aims of the present study were to assess the feasibility of let‑7e as a serum marker for detecting KOA and to explore the underlying mechanisms of its involvement. Based on previous studies and bioinformatics analysis, let‑7e may regulate apoptosis and autophagy of articular chondrocytes. A total of 10 patients with KOA and 10 patients with trauma without KOA were recruited to examine the levels of let‑7e in peripheral blood. Subsequently, KOA rat models were established, and the levels of let‑7e in the cartilage and serum were examined, the expression of apoptotic proteins a
