Annexin A2-modulated proliferation of pulmonary arterial smooth muscle cells depends on caveolae and caveolin-1 in hepatopulmonary syndrome.
    Experimental cell research, 2017, 10-01, Volume: 359, Issue:1

    We have established that annexin A2 (ANXA2) is an important factor in the experimental hepatopulmonary syndrome (HPS) serum-induced proliferation of pulmonary arterial smooth muscle cells (PASMCs). However, the detailed mechanism remains unclear. ANXA2 translocated to the caveolin-enriched microdomains (caveolae) in PASMCs upon HPS serum stimulation. The disruption of caveolae by Methyl-β-cyclodextrin (MβCD) alleviated the caveolae recruitment of ANXA2 and the ANXA2-mediated activation of ERK1/2 and NF-κB, so that ANXA2-modulated PASMC proliferation was suppressed. The over-expression of Cav-1 resulted in the relocation of ANXA2 from caveolae and negatively regulated ERK1/2 and NF-κB activation, which inhibited the ANXA2-modulated PASMC proliferative behavior. These data indicate that caveolae function as a signaling platform for ANXA2-induced proliferative behavior and Cav-1 participates upstream of ANXA2 in the activation of ERK1/2 and NF-κB.
