(D) Schematic model depicting the function of Alivec in AngII-induced VSMC chondrogenic transition. In RVSMCs, AngII induces lncRNA Alivec by way of activation of AngII form 1 receptor (AT1R) and downstream transcription element Sox9, a master regulator of chondrogenesis. In turn, Alivec localized in the nucleus modulates Sox9-induced expression of chondrogenic genes, for instance nearby Acan potentially by means of enhancer activity, and distantly localized AdipoRon supplier Tnfaip6, Runx1 and Spp1 by way of trans-acting mechanisms to market chondrogenesis. Interaction with nuclear proteins, for instance hnRNPA2B1 may possibly play a part in Alivec mediated gene regulation. Whereas, interactions inside the cytoplasm of Alivec with Tpm3 proteins may possibly disrupt contractile functions of VSMC. Hence, Alivec could play an important part in AngII-induced RVSMC phenotypic, switching from contractile to pathologic phenotypes associated with hypertension and CVDs.4.
