(D) Schematic model depicting the role of Alivec in AngII-induced VSMC chondrogenic transition. In RVSMCs, AngII induces lncRNA Alivec by means of activation of AngII form 1 receptor (AT1R) and Khellin site downstream transcription aspect Sox9, a master regulator of chondrogenesis. In turn, Alivec localized within the nucleus modulates Sox9-induced expression of chondrogenic genes, like nearby Acan potentially by way of enhancer activity, and distantly localized Tnfaip6, Runx1 and Spp1 by means of trans-acting mechanisms to market chondrogenesis. Interaction with nuclear proteins, for instance hnRNPA2B1 may perhaps play a function in Alivec mediated gene regulation. Whereas, interactions inside the cytoplasm of Alivec with Tpm3 proteins may well disrupt contractile functions of VSMC. Thus, Alivec may possibly play a crucial part in AngII-induced RVSMC phenotypic, switching from contractile to pathologic phenotypes linked with hypertension and CVDs.four.
