??OBJECTIVE To investigate the protective effect of epalrestat on right ventricular remodeling in a rat model of monocrotaline-induced pulmonary arterial hypertension(PAH). METHODS PAH rats were induced by a single injection of monocrotaline(60 mg??kg^-1, sc) and were administered epalrestat(50 or 100 mg??kg^-1) for 4 weeks. At the end of experiment, the right ventricular systolic pressure(RVSP) and mean pulmonary artery pressure(mPAP) were monitored via the right jugular vein catheterization into the right ventricle. Right ventricle(RV) and left ventricle(LV)+septum(S) were isolated and weighed, and ratios of RV/(LV+S)and RV to tibial length were calculated. Right ventricular morphological change was observed by HE staining. Masson??s trichrome stain was used to demonstrate collagen deposition. The total antioxidative capacity(T-AOC) and malondialdehyde(MDA) levels in right ventricle were determined according to the manufacturer??s instructions. The expression of collagen I, collagen ??, AR and NOX4 were analyzed by immunohistochemisty, real-time PCR or Western blot. RESULTS The results showed that epalrestat treatment for 4 weeks attenuated RVSP, mPAP and right ventricular remodeling index(RV/LV+S and RV/Tibial length) of PAH rats induced by monocrotaline. Furthermore, monocrotaline-induced right ventricular collagen accumulation and collagen I and collagen III expression were both significantly suppressed by epalrestat. The expressions of AR, NOX4 and MDA content were obviously decreased, while the T-AOC was significantly increased in right ventricular from PAH rats with epalrestat treatment. CONCLUSION These results suggest that epalrestat ameliorates right ventricular remodeling of PAH induced by monocrotaline in rats through its down-regulating of AR and NOX4 expression and collagen accumulation.

??OBJECTIVE To investigate the cardioprotective effect of exogenous zinc (Zn²⁺)on the mitochondrial pathway, and to explore its possible mechanism. METHODS Rat heart tissue-derived H9c2 cardiac cells were cultured, and then randomly divided into control group, ZnCl₂ group (1-20 ??mol??L^-1, 20 min), ZnCl₂ plus inhibitor group [PI3K inhibitor LY294002, 10 ??mol??L^-1 and mitochondrial ATP sensitive potassium channel (mKATP) inhibitor 5-HD, 0.5 mmol??L^-1, inhibitors treated cells for 10 min and then ZnCl₂ 20 min] and inhibitor group (10 min). The mitochondrial permeability transition pore (mPTP) opening was evaluated by measuring mitochondrial membrane potential (????m). Tetramethylrhodamine ethyl ester (TMRE) diacetate fluorescence images were obtained with laser scanning confocal microscopy. GSK-3?? and AKT phosphorylation were determined with Western blot. The cells were subjected to simulated ischemia/reperfusion injury, cell viability were determined with flow cytometry. Cells were transfected with constitutively active GSK-3??-S9A(GSK-3??-S9A)plasmid by Fugene 6 transfection kit, mPTP opening was evaluated by confocal microscopy. RESULTS Compared with the normal, exposure of cells to H₂O₂ for 20 min caused a marked decrease in TMRE fluorescence, treatment of cells with different dose of Zn²⁺ prevented the loss of TMRE fluorescence caused by H₂O₂ with the peak at 10 ??mol??L^-1. Western blot showed that Zn²⁺significantly enhanced the GSK-3?? and AKT phosphorylation, the effect that was significantly reversed by LY294002, but not 5-HD. Compared with the normal, ischemia/reperfusion markedly reduced cell viability. Zn²⁺ applied at ischemia did not increase the cell viability, but significantly increased the cell viability when given at reperfusion. Zn²⁺could mimic the specific mPTP inhibitor cyclosporin A (1 ??mol??L^-1) and prevent the mPTP opening, which was again reversed by LY294002 but not 5-HD. Zn²⁺ was not able to exert protection in cells transfected with the GSK-3??-S9A. CONCLUSION Zn²⁺ can induce myocardial mitochondrial protective effect by modulating the mPTP opening through the inactivation of GSK-3?? via PI3K/AKT pathway. mKATP may not be involved in the action of Zn²⁺.

??OBJECTIVE To examine the expression of 15-hydroxyprostaglandin dehydrogenase(15-PGDH) in human multidrug-resistant breast cancer line MCF-7/ADR and to explore the reversal effect and mechanism of 15-PGHD induction drugs on MCF-7/ADR cells. METHODS The RT-PCR and Western blot were used to detect 15-PGDH, COX-2 mRNA and protein expression in MCF-7 and MCF-7/ADR cells. PGE₂ levels in supernatant of cells were determined by ELISA assay. Anti-proliferation effect and chemotherapy sensitivity to ADM of 15-PGDH induction drugs (indomethacin, ibuprofen and pioglitazone, dexamethasone) on breast cancer cells were assayed by MTT method. Cell apoptosis was detected by Hochest 33258 stain assay. RESULTS Compared with MCF-7 cells, the 15-PGDH expression was significantly decreased, COX-2 expression was significantly increased and PGE₂ levels in cell supernatant were increased in MCF-7/ADR cells. 15-PGDH induction drugs (indomethacin, ibuprofen and pioglitazone, dexamethasone) increased 15-PGDH expression or both reduced COX-2 expression, and finally reduced PGE₂ levels in MCF-7/ADR cells. Effect of chemosensitivity and apoptosis induction of ADM was enhanced and multidrug resistance was partially reversed when co-treated with 15-PGDH induction drugs. CONCLUSION The expression of 15-PGDH is decreased in human multidrug-resistant breast cancer line MCF-7/ADR. 15-PGDH induction drugs could increase chemosensitivity, promote apoptosis and reverse resistance of MCF-7/ADR cell, the mechanism might related to the influence of PGE₂ level by regulated the expression of 15-PGDH and COX-2.

??OBJECTIVE To explore the effects of luteolin on the proliferation and migration of the endothelial cells co-cultured with cancer cells and its molecular mechanism. METHODS Human umbilical vein endothelial cells (HUVECs) were primarily isolated and identified by the expression of VE-cadherin. Cancer-endothelial cell co-culture model was established using the Transwell system. The effects of luteolin at different concentrations (0 [Co-culture control], 20 and 50 ??mol??L^-1) on the proliferation and migration of HUVECs in the co-culture system were determined. A HUVECs control group removed of prostate cancer PC3 cells was also included. Human angiogenesis antibody array kit was used to assay the secretion levels of various protein factors in each group. RESULTS VE-cadherin was expressed on all the cultured HUVECs. Increased proliferation ability was found in the HUVECs co-cultured with PC3 cells compared with that in HUVECs control group (P<0.01). Treatment with 20 or 50 ??mol??L^-1 luteolin significantly inhibited the proliferation ability of the HUVECs in co-culture system (both P<0.01). Increased migration ability was found in the HUVECs co-cultured with PC3 cells compared with that in HUVECs control group (P<0.01). Treatment with 20 or 50 ??mol??L^-1 luteolin significantly inhibited the migration ability of the HUVECs in co-culture system (both P<0.01). Secretion levels of multiple angiogenesis-related proteins in the cultural supernatant of co-culture system were significantly increased compared with those in HUVECs control group. Treatment with 20 ??mol??L^-1 luteolin significantly inhibited the secretion levels of interleukin-8 (IL-8), vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1(MCP-1) in the cultural supernatant of co-culture system (all P<0.01). CONCLUSION Luteolin may inhibit the proliferation and migration of endothelial cells via suppressing the secretions of IL-8, VEGF and MCP-1 in cancer-endothelial co-culture system.
