Abstract EN
Purpose.
This study aimed to explore whether bone marrow- (BM-) derived endothelial progenitor cells (EPCs) contributing to monocrotaline- (MCT-) induced pulmonary arterial hypertension (PAH) in rats via modulating store-operated Ca2+ channels (SOC).
Methods.
Sprague Dawley (SD) rats were assigned into MCT group (n = 30) and control group (n = 20).
Rats in MCT group were subcutaneously administered with 60 mg/kg MCT solution, and rats in control group were injected with equal amount of vehicle.
After 3 weeks of treatment, right ventricular systolic pressure (RVSP) and right ventricular hypertrophy index (RVHI) of two groups were measured, and BM-derived EPCs were isolated.
Immunochemistry identification and vasculogenesis detection of EPCs were then performed.
Ca2+cyt measurement was performed to detect store-operated calcium entry (SOCE) in two groups, followed by determination of Orai and canonical transient receptor potential (TRPC) channels expression.
Results.
After 3 weeks of treatment, there were significant increases in RVSP and RVHI in MCT group compared with control group, indicating that MCT successfully induced PAH in rats.
Moreover, the SOCE (Ca2+cyt rise) in BM-derived EPCs of MCT group was lower than that of control group.
Furthermore, the expression levels of Orai3, TRPC1, TRPC3, and TRPC6 in BM-derived EPCs were decreased in MCT group in comparison with control group.
Conclusions.
The SOC activities were inhibited in BM-derived EPCs of MCT-treated rats.
These results may be associated with the depressed expression of Orai3, TRPC1, TRPC3, and TRPC6, which are major mediators of SOC.
