The gene expression level of each indicator was consistent with the protein expression level. There was no significant difference in the indicators between groups 1 and 3. The percentage of EdU-positive cells in group 2 was higher than that in the other two groups (P<0.05). The expression of pSmad2 and Col2 in group 2 was higher than that in the other two groups (both P<0.05). FBLN1 can promote chondrocyte proliferation in the knee cartilage in elderly patients by phosphorylating Smad2. FBLN1 can promote chondrocyte proliferation in the knee cartilage in elderly patients by phosphorylating Smad2.The evolutionarily conserved Piezo channel family, including Piezo1 and Piezo2 in mammals, serves as versatile mechanotransducers in various cell types and consequently governs fundamental pathophysiological processes ranging from vascular development to the sense of gentle touch and tactile pain. Piezo1/2 possess a unique 38-transmembrane (TM) helix topology and form a homotrimeric propeller-shaped structure comprising a central ion-conducting pore and three peripheral mechanosensing blades. The unusually curved TM region of the three blades shapes a signature nano-bowl configuration with potential to generate large in-plane membrane area expansion, which might confer exquisite mechanosensitivity to Piezo channels. Here, we review the current understanding of Piezo channels with a particular focus on their unique structural designs and elegant mechanogating mechanisms.miRNAs are short RNA molecules regulating multiple cellular processes through post-transcriptional gene silencing. Over the past decade, miRNAs have been found in the extracellular space and have been consistently shown to mediate functional communication between cells. While it remains widely accepted that miRNA transfer between
