AIM:To investigate the ability of a metal complex ammonium tetrathiomolybdate (ATTM) to re-lease H2 S and its cytoprotective effect on an oxidative injury model .METHODS:Released H2 S was absorbed in a reaction flask from ATTM dissolved in the cell medium .Staining with dichlorodihydrofluorescein diacetate or rhodamine 123 fol-lowed by photofluorography was conducted for the observation of reactive oxygen species ( ROS) and mitochondrial mem-brane potential (ΔΨm) levels, respectively.Cell viability and release of lactate dehydrogenase (LDH) from the cells were measured with commercial kits.RESULTS:Similar to another H2S donor GYY4137, ATTM had an ability to release H2S in the cell medium in a dose-dependent manner .Treatment of human skin HaCaT cells with ATTM at concentrations of 25~400 μmol/L didn’ t significantly alter cell viability .Exposure of the cells to ultraviolet rays or a ROS donor H 2 O2 in-creased the intracellular ROS levels .Treatment with 400 μmol/L H2 O2 significantly reduced the viability of HaCaT cells (P<0.01).However, before the treatment with H2O2, pretreatment with ATTM at 100 and 200 μmol/L markedly pre-vented the H2O2-induced cell injury (P<0.01).In addition, the treatment with H2O2 triggeredΔΨm loss (P<0.01) and LDH release from the cells (P<0.01).Prior to suffering from H2O2 injury, the preconditioning with 200 μmol/L ATTM significantly improved ΔΨm levels ( P<0.05 ) and attenuated LDH release from the cells ( P<0.01 ) .CONCLUSION:ATTM is capable of releasing H 2 S and protecting human skin cells against oxidative injury .

ObjectiveTo explore the role of β-catenin in the proinvasive consequences of hypoxia in hepatocellular carcinoma (HCC).MethodsWe established in vitro and in vivo hypoxic models using the highly metastatic MHCC97 and the stable red fluorescent protein-expressing MHCC97-R cells.The role of β-catenin in hypoxia-mediated aggressiveness was investigated by β-catenin knockdown.ResultsHypoxia caused a pronounced arrest of proliferation in MHCC97 cells,suppressed tumor growth in MHCC97-R xenografts,but promoted in vitro invasiveness and in vivo metastasis.β-Catenin-silencing by short hairpin significantly inhibited the enhanced invasiveness of MHCC97 cells due to hypoxia,reduced the increase in distant metastasis by hepatic arterial ligation,but failed to further restrain cell proliferation.Conclusionβ-Catenin in HCC cells plays an essential role in the hypoxia-induced metastatic potential.A reduction of βcatenin expression inhibited the proinvasive consequences of hypoxia in HCC.

Objective To estimate the influences of N-acetyl cysteine (NAC) on a chemical hypoxiamimetic agent CoCl2 induced-injury to, and expressions of inflammatory factors by, an immortal human skin keratinocyte line HaCaT. Methods HaCaT cells were treated with CoCl2 of 2000 μmol/L for 4 hours to set up a chemical hypoxia-induced cell model of skin injury. NAC of various concentrations ( 1000, 2000, 3000 μmol/L)was used to pretreat HaCaT cells for 2 hours prior to the establishment of cell model. After these treatments,cell viability was detected by cell counting kit 8 (CCK-8), the levels of interleukin 6 and 8 (IL-6 and -8) and tumor necrosis factor α (TNF-α) in culture supernatant by ELISA kits, mitochondrial membrane potential (MMP) by rhodamine 123 (Rh123) staining and photofluorography, intracellular reduced glutathione (GSH)content by glutathione detection kit. Results An obvious decline was observed in HaCaT cell viability after pretreatment with various concentrations of NAC for 2 hours. The treatment with CoCl2 of 2000 μmol/L for 4 hours induced an elevation in the supernatant levels of IL-6, IL-8 and TNF-α and a decrease in GSH content and MMP, while the pretreatment with NAC for 2 hours retarded the CoCl2-induced increase in IL-6 and IL-8 levels as well as decrease in GSH content and MMP. Conclusion The reactive oxygen species (ROS) scavenger NAC can protect against CoCl2-induced injury to and inflammatory reaction in HaCaT cells, which may be associated with a decrement in oxidative stress.

BACKGROUND: Recent studies indicate that bone marrow messenchymal stem cells (MSCs) can repairinjured myocardium and improve cardiac functions. However, there are still no effective non-invasive methods to detect ventricular wall motion, survival status of transplanted cells, and microcirculation improvement after MSCsimplantation. OBJECTIVE: To detect the effects of MSCs implantation on the cardiac function of ischemic myoeardium and investigate changes of tissue acoustics characteristics by using integrated backscatter (IBS) and Doppler tissue imaging (DT1). DESIGN, TIME AND SETTING: Completely randomized grouping design, and randomized controlled study, which was carried out in the Department of Cardiology, Renmin Hospital of Wuhan University from December 2004 to June 2005 (important laboratory of 211 government). MATERIALS: Forty-eight male rabbits with irrespective of gender were used for study. Anti-troponin T (TnT) antibody was provided by Maxim Company, USA; anti-bromodeoxyuridine (BrdU) antibody by Sigma Company, USA; Sonos 5500 echocardiography by HP Company, USA.METHODS: Forty-eight rabbits were randomly divided into model group and implantation group. Model of myocardium infarction was created in rabbits by left anterior descending coronary artery (LAD) ligation. Three days after modeling, autologous bone marrow MSCs were injected into crossed myocardium between infarction and non-infarction regions based on 5 injected points.MAIN OUTCOME MEASURES: Indicators including ventricular size, ventricular wall thickness, and ejection fraction (EF) in the left ventricle (LV) were measured with routine echocardiography one day before myocardial infarction, two weeks after myocardial infarction, and four weeks after implantation. IBS and DTI might detect the anterior backscatter parameters (AII, or IB) and ventricular wall motion parameters (PPI, or CVIB) to calculate the average backscatter scores and backscatter cycle changes. DTI was used to measure peak systolic flow velocity (VS), peak early diastolic flow velocity (VE), and peak late diastolic flow velocity (VA) of the middle and basal segments of the anterior wall of left ventricle. Finally, animals were sacrificed by anesthesia, and myocardial infarction region was stained with 5-Brdu immunohistochemical staining, and anti-TnT staining. RESULTS: Twelve rabbits were excluded because of death after operation.① Echocardiography: Imaging of 36 rabbits were clear in 1 day before myocardial infarction, 2 weeks after myocardial infarction, and 4 weeks after implantation. The sizes and systolic function of LV in 36 rabbits were normal before operation. Two weeks after operation, the sizes of LV became larger, the anterior wall of LV became thinner, and systolic range became weaker even disappeared. EF, CVIB, Vs, and Ve were lower (P < 0.05) and All was higher in both groups than pre-operation (P < 0.05). Four weeks after implantation, compared with control group, left ventricular diastolic diameter (LVDd) was smaller and systolic range became larger, All descended. EF, Vs, Ve and CVIB increased (P < 0.05).② Myocardial immunohistochemical detection: Numerous of Brdu-labeled positive cells were scattered, and anti-TnT was positive, which clearly showed horizontal stria of myocardium. However, normal myocardium was negative. CONCLUSION: Bone marrow MSCs after implantation can survive in ischemic myocardium and improve cardiac function. IBS and DTI can real-timely and exactly detect functional changes of infarction myocardium after bone marrow MSCs implantation.

Aim To explore the effect of survivin in PC12 cells against injuries induced by cobalt chloride(CoCl_2).Methods PC12 cells were exposed to CoCl_2 at different doses in different time to set up the chemical hypoxia induced PC12 cells injuries model.Cell viability was tested by using cell counter kit-8.Dose-effect(200～1 000 μmol·L~(-1))and time-effect(0～48 h)relationship between hypoxia induced by CoCl_2 and the expression of survivin was evaluated by western blot.Results PC12 cells viability was inhibited significantly by CoCl_2 in a dose and time dependent manners;At the concentrations from 200 to 600 μmol·L~(-1) CoCl_2 for 24 h,survivin expression was upregulated in a dose dependent manner,peaking at 600 μmol·L~(-1) CoCl_2 treatment,exceeding this concentration of CoCl_2,with dose increasing,survivin expression decreased.At the dose of CoCl_2 up to 1 000 μmol·L~(-1),survivin did not express basically;Treatment with 600 μmol·L~(-1) CoCl_2 in different time,within the range of 0～36 h,the expression of survivin enhanced in time dependent manner.But with the extension of time,survivin expression was declining; 17-allylamino-17-demethoxygeldanamycin (2 μmol·L~(-1)),an inhibitor of Hsp90,not only decreased survivin overexpression but also obviously enhanced the injuries of PC12 cells induced by CoCl_2,which didn't damage PC12 cells alone.Conclusion Upregulation of survivin expression may be one of the endogenous defense mechanisms for PC12 cells against chemical hypoxia.
