Role of Protein Transamidation in Serotonin-Induced Proliferation and Migration of Pulmonary Artery Smooth Muscle Cells

The role of autophagy in advanced glycation end product-induced proliferation and migration in rat vascular smooth muscle cells

Objective(s): To investigate the role of autophagy in advanced glycation end products (AGEs)-induced proliferation and migration in rat vascular smooth muscle cells (VSMCs).Materials and Methods: After culture, VSMCs were treated with 0, 1, 10, and 100 μg/ml concentrations of AGEs. Autophagy specific protein light chain 3 (LC3)-I/II was determined by western blotting, autophagosomes were observ...

JNK regulates serotonin-mediated proliferation and migration of pulmonary artery smooth muscle cells.

JNK is a member of the MAPK family and has essential roles in inflammation and cell differentiation and apoptosis. In recent years, there have been accumulating data indicating a novel role for JNK in cell growth and migration. In this report, we demonstrate that JNK activity is necessary for serotonin (5-HT)-induced proliferation and migration of bovine pulmonary artery smooth muscle cells (PA...

Tanshinone IIA inhibits AGEs-induced proliferation and migration of cultured vascular smooth muscle cells by suppressing ERK1/2 MAPK signaling

Objective(s): Vascular smooth muscle cells (VSMCs) play a key role in the pathogenesis of diabetic vascular disease. Our current study sought to explore the effects of tanshinone IIA on the proliferation and migration of VSMCs induced by advanced glycation end products (AGEs). Materials and Methods: In this study, we examined the effects of tanshinone IIA by cell proliferation assay and cell mi...

Role of adenylyl cyclase in proliferation of neonatal pulmonary artery smooth muscle cells.

Role of hypoxia-induced transglutaminase 2 in pulmonary artery smooth muscle cell proliferation.

We previously reported that transglutaminase 2 (TG2) activity is markedly elevated in lungs of hypoxia-exposed rodent models of pulmonary hypertension (PH). Since vascular remodeling of pulmonary artery smooth muscle cells (PASMCs) is important in PH, we undertook the present study to determine whether TG2 activity is altered in PASMCs with exposure to hypoxia and whether that alteration partic...
