Study on the mechanism of echinacoside in preventing and treating hypoxic pulmonary hypertension based on proteomic analyses.
Hypoxic pulmonary hypertension (HPH), a chronic condition affecting the cardiopulmonary system, has high mortality. Echinacoside (ECH) is a phenylethanoid glycoside, which is used to ameliorate pulmonary vascular remodeling and pulmonary vasoconstriction in rats. Accordingly, we aimed to explore the mechanism of ECH in preventing and treating HPH. Sprague Dawley rats were housed in a hypobaric hypoxia chamber for 28 days to obtain the HPH model. The experimental rats were randomly allocated into the following several groups: normoxia group, chronic hypoxia group, and ECH group. The therapeutic results of ECH (10, 20, and 40 mg/kg) showed that ECH reduced mPAP, Hb, Hct, and RVHI in HPH rats. Then this work employed label-free quantitative proteomic analysis, western blotting, and RT-PCR to investigate the mechanism by which ECH prevents HPH. The results found that in the chronic hypoxia group, the levels of ACSL1, COL6A1, COL4A2, COL1A1, and PC increased compared to the normoxia group. However, the opposite effect was observed in the chronic hypoxia group treated with ECH. The study indicates that the administration of ECH may slow the pathological progression of HPH by suppressing the inflammatory response, inhibiting smooth muscle cell proliferation, and minimizing the deposition of extracellular matrix.
期刊介绍:
PR&P is jointly published by the American Society for Pharmacology and Experimental Therapeutics (ASPET), the British Pharmacological Society (BPS), and Wiley. PR&P is a bi-monthly open access journal that publishes a range of article types, including: target validation (preclinical papers that show a hypothesis is incorrect or papers on drugs that have failed in early clinical development); drug discovery reviews (strategy, hypotheses, and data resulting in a successful therapeutic drug); frontiers in translational medicine (drug and target validation for an unmet therapeutic need); pharmacological hypotheses (reviews that are oriented to inform a novel hypothesis); and replication studies (work that refutes key findings [failed replication] and work that validates key findings). PR&P publishes papers submitted directly to the journal and those referred from the journals of ASPET and the BPS
