HPASMC has been used to show that IL-22 promotes the growth of pulmonary vascular SMCs via a signaling mechanism that involves NADPH oxidase-dependent oxidation (Bansal, 2013). Inducers of pulmonary hypertension, characterized by thickened pulmonary arterial walls, activate expression of anti-apoptotic Bcl-xL gene via binding of GATA-4 to its promoter; the activation can be suppressed by targeting gata4 gene transcription (Suzuki, 2007). Serotonin induces growth of Pulmonary Artery Smooth Muscle Cells and is able to transactivate the BMP receptor in pulmonary artery SMCs, leading to activation of Smads 1/5/8 via Rho and Rho kinase pathway (Liu, 2009). Pulmonary Artery Smooth Muscle Cells growth can be suppressed by trans-retinoic acid by inducing expression of GADD45A, a known cell growth suppressor, downstream of the retinoid acid receptors RARalpha, RARbeta, RARgamma, RXRalpha, and RXRbeta, indicating possible involvement of retinoic acid in pulmonary vascular remodeling (Preston, 2005). Treatment of Pulmonary Artery Smooth Muscle Cells with plasma containing reduced levels of all-trans RA and 13-cis RA promoted cell growth (Day, 2009). Retinoic acid was also shown to inhibit migration of pulmonary smooth muscle cells by inhibiting PI3K/Akt-dependent reorganization of actin cytoskeleton (Day, 2006). Pulmonary Artery Smooth Muscle Cells were also used to study effects of iron chelation on vascular remodeling and its implications for development of pulmonary hypertension as a result of ROS activity (Wong, 2012). Finally, these cells were used to show that antitumor drugs can selectively target remodeled pulmonary vessels, but not normal vessels (Ibragim, 2014).

Characterization: positive for smooth muscle cell specific alpha-actin expression.
