The effectiveness of alprostadil in treating coronary microcirculation dysfunction following ST-segment elevation myocardial infarction in a pig model. Exp Ther Med 2021; 22:1449. [PMID: 34721691 PMCID: PMC8549090 DOI: 10.3892/etm.2021.10884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Accepted: 11/19/2020] [Indexed: 11/25/2022] Open
Abstract
Though alprostadil has been reported to improve the impaired microcirculation of patients with pulmonary arterial hypertension, its effectiveness as a treatment for coronary microvasculature dysfunction (CMD) following ST-segment elevation myocardial infarction (STEMI) is unknown. A total of 18 miniature pigs with CMD following STEMI were randomized into three groups that received an intracoronary injection of 5 ml of normal saline, 2 mg of nicorandil or 10 µg of alprostadil immediately after measurement of the index of microcirculatory resistance (IMR) and then an intravenous drip containing 5 ml of normal saline, 2 mg of nicorandil or 10 µg of alprostadil once a day for 6 days. The IMR, cardiac function using ultrasound, infarct areas and heparanase levels in infarct areas were measured and compared between the three groups. The IMR decreased markedly 10 min after alprostadil or nicorandil intracoronary injection (both P<0.05) but not following saline injection (P>0.05). After 7 days, the IMR was substantially lower in the alprostadil and nicorandil groups compared with the saline group (both P<0.05) and the ejection fraction was considerably higher in the alprostadil and nicorandil groups compared with the saline group (both P<0.05). Differences in infarct areas and the relative heparanase expression levels among the 3 groups were similar to the differences in the ejection fraction. No significant differences in the above assessment indexes were identified in the alprostadil and nicorandil groups. Alprostadil infusion improved coronary microcirculation function, reduced the infarct area and limited left ventricular dilatation in a pig coronary microvasculature dysfunction model following STEMI.

Abstract
Mesenchymal stem cells (MSCs) have become a recent focus of experimental and clinical research regarding myocardial regeneration. However, the therapeutic potential of these cells is limited by poor survival. Prostaglandin E1 (PGE1) is known to have anti-inflammatory and anti-apoptotic effects on the myocardium. The aim of the present study was to determine whether PGE1 could protect MSCs against serum deprivation (SD)-induced apoptosis. An SD model was used to induce apoptosis in MSCs in vitro. Apoptotic morphological changes were detected by Hoechst 33258 fluorescent nuclear staining; and Annexin V-fluorescein isothiocyanate/propidium iodide (PI) double staining and flow cytometry was used to quantify the rate of apoptosis. Western blot analysis was used to detect the expression levels of the apoptosis-associated proteins Bcl-2, Bax and caspase-3. The results of the present study demonstrated that SD induced apoptosis of MSCs, and that treatment with PGE1 attenuated the morphological changes characteristic of apoptosis. Annexin V/PI staining showed that the rate of apoptosis gradually increased with the duration of ischemia. Furthermore, treatment with PGE1 significantly reduced SD-induced apoptosis, decreased the protein expression levels of Bax and caspase-3, and increased the expression levels of Bcl-2. These data suggest that PGE1 is able to influence the survival of MSCs under certain conditions. These results may aid in improving the therapeutic efficacy of MSC transplantation used to treat chronic ischemic heart disease.

Abstract
A nonrandomized controlled study was conducted to evaluate the effect of lipo-prostaglandin E1 (lipo-PGE1) on cystatin C (CysC), β2-microglobulin (B2MG), and estimated glomerular filtration rate (eGFR) in patients with decompensated heart failure (DHF) and renal dysfunction. A total of 286 enrolled patients with DHF and renal dysfunction were nonrandomly assigned a 7-day standard treatment without (n = 146) or with (n = 140) lipo-PGE1 intervention. According to the baseline eGFR, patients were further classified into mild, moderate, and severe renal dysfunction subgroups. By the end of study period, there was no evidence of an immense improvement in B2MG, CysC, and eGFR in response to standard treatment (all P > 0.05). On the contrary, a noticeable decrease of B2MG and CysC was observed in patients receiving lipo-PGE1 intervention, as well as an increase in eGFR (all P < 0.05). Moreover, lipo-PGE1 intervention led to greater changes in renal function variables from baseline than with standard management (all P < 0.05). Most important, the favorable renal protective effects of lipo-PGE1 were maintained in three subgroups. Lipo-PGE1 intervention brought a substantial renoprotective benefit to hospitalized DHF patients as compared with standard therapy, suggesting it might offer a promising therapeutic option for the management of renal dysfunction associated with DHF.

Abstract
All animals require molecular oxygen for aerobic energy production, and oxygen availability has played a particularly important role in the evolution of aquatic animals. This study investigates how previous exposure to hypoxia (preconditioning) primes protective transcriptional responses in a hypoxia-tolerant vertebrate species, the epaulette shark (Hemiscyllium ocellatum). The epaulette shark is a basal cartilaginous fish that in its natural environment experiences cyclic hypoxic periods. We evaluated whether the transcription of a set of crucial prosurvival genes is affected differently by a single short-term (2 h) exposure to sublethal hypoxia compared with eight such successive hypoxia exposures (hypoxia preconditioning). We discovered that hypoxia preconditioning amplifies transcriptional responses compared with animals that experienced a single hypoxic bout. In the heart we observed that hypoxic preconditioning, but not a single hypoxic exposure, resulted in higher transcript levels of genes that regulate oxygen and energy homeostasis, including those of hypoxia-inducible factor-1 alpha, adenosine signaling pathway components, and genes affecting circulation [prostaglandin synthetase 2 (cox-2) and natriuretic peptide C]. This suggests that in a single short-term hypoxic bout, the responses to low oxygen are regulated at the level of pre-existing proteins or translational and posttranslational machinery, whereas transcriptional responses are induced in experiments that parallel the natural environmental cycles of oxygen availability. These findings have general implications for understanding how vertebrates regulate protective gene expression upon physiological stress.
