Calcific aortic valve disease (CAVD) primarily involves osteogenic differentiation in human aortic valve interstitial cells (hVICs). Schisandrol B (SolB), a natural bioactive constituent, has known therapeutic effects on inflammatory and fibrotic disorders. However, its impact on valve calcification has not been reported. Transcriptome sequencing was used to analyze potential molecular pathways affected by SolB treatment. To explore the therapeutic mechanism of SolB, human valve interstitial cells were induced to undergo osteogenic differentiation by OM, with or without SolB treatment meanwhile. Among the signaling pathways enriched, the P53 signaling pathway was identified as the upstream regulator of other enriched pathways such as Cell cycle, Oocyte meiosis, Cytokine-cytokine receptor interactions. These pathways were regulated by the P53 signaling pathway and were reported to be stimulated by DNA damage, an early stage of pathological change in CAVD. The cytokine-cytokine receptor interaction signaling pathway was reported to correlate with calcified aortic valve disease. taken together, our data revealed potential therapitic mechanism p53 signaling of Schisandrol B treatment in hVICs calcification. Overall design: To explore the therapeutic mechanism of SolB, human valve interstitial cells were induced to undergo osteogenic differentiation by OM, with or without SolB treatment meanwhile. Less...
