JAK2/STAT3信号通路介导灯盏花乙素抗人心脏微血管内皮细胞缺氧-复氧损伤

Objective: To investigate the antagonistic cell injury effect and molecular mechanism of scutellarin(SCU)in hypoxia reoxygenation(HR) treated human cardiac microvascular endothelial cells(HCMECs).Methods: The method of 12 h hypoxia following by 12 h reoxygenation was used to culture HCMECs in vitro to built cell injury model. The groups were divided into control group, model(HR) group, and HR + SCU(0.1 μmol/L, 1 μmol/L, and 10 μmol/L) group. The cell viability was determined by MTT, and oxidative stress was detected by malondialdehyde(MDA) levels by biochemical assay kit. Protein expression of JAK2/p-JAK2 and STAT3/p-STAT3 were evaluated by Western blot.Results: The results of MTT and MDA showed that HR decreased the cell viability(P 0.05) and increased MDA level significantly(P 0.05), SCU played a contrary role in these processes. Western blot analysis indicates that, the expression of JAK2 and p-JAK2, STAT3, and p-STAT3 were increased in model group when compared with control group(P 0.05); Compared with model group, their expression were reduced by SCU(P 0.05).Conclusion: SCU took a protective effect on HR-treated HCMECs, and the molecular mechanism may be associated with the inhibition of JAK2/STAT3 signal transduction pathway.

Antioxidative and in vitro hepatoprotective activity of Bupleurum kaoi leaf infusion

The roots of Bupleurus spp. have been used in traditional Chinese herbal medicine for curing liver diseases. Although bioactive saikosaponins have been detected in the leaves as well as in the roots, the aerial parts of the plants are discarded as waste. In the present study, a leaf infusion of B. kaoi Liu, Chao et Chuang, an indigenous Bupleurus species in Taiwan, was prepared and the antioxidant properties and in vitro hepatoprotective activity were demonstrated. The results show that the leaf infusion exerted DPPH free radical scavenging activity, inhibitory capacity on superoxide anion formation and superoxide anion scavenging activity. The hepatotoxicity of acetaminophen (APAP) and carbon tetrachloride (CCl4) on the rat liver cells were also decreased by the leaf infusion.     

Effect of EGb761 on light-damaged retinal pigment epithelial cells

AIM:To investigate the protective mechanism of Gingko Biloba extract (EGb761) on the ability of retinal pigment epithelial (RPE) cells to resist light-induced damage in a comparative proteomics study.METHODS:Human RPE cells (ARPE-19) were randomly distributed to one of three groups:normal control (NC group) and light-damaged model without or with EGb761 group (M and ME groups, respectively). The light-damaged model was formed by exposing to white light (2 200±300)lx for 6h. The RPE cells in ME group were conducted with EGb 761 (100μg/mL) before light exposure. The soluble cellular proteins extracting from each groups were separated by two-dimensional electrophoresis and stained by silver staining. Different proteins in the profiles of the gels were analyzed by Image Master Software. Two-fold expressing protein spots were identified by Matrix-assisted laser desorption/ionization tandem time-of-flight (MALDI-TOF/TOF) mass spectrometry.RESULTS: NC, M and ME groups displayed 1 892±71, 2 145±23 and 2 216±85 protein spots, respectively. We identified 33 proteins with different expression levels between the NC and M groups, 25 proteins between the M and ME groups, and 11 proteins between the NC and ME groups. MALDI-TOF/TOF mass spectrometry successfully identified 16 proteins, including metabolic enzymes, cytoskeletal proteins, anti-oxidation proteins, and others.CONCLUSION:Differences in some important proteins, such as cathepsin B, heat shock protein, and cytochrome creductase, indicated that multiple pathways may be induced in light-damaged RPE cells and the protective effect of EGb761.

Visual targeted therapy of hepatic cancer using homing peptide modified calcium phosphate nanoparticles loading doxorubicin guided by T1 weighted MRI

Effective treatment and real-time monitoring of hepatic cancer are essential. A multifunctional calcium phosphate nanoparticles loading chemotherapeutic agent doxorubicin and magnetic resonance imaging contrast agent diethylenetriaminepentaacetic acid gadolinium (A54-CaP/Gd-DTPA/DOX) was developed for visual targeted therapy of hepatic cancer via T1-weighted MRI in real-time. A54-CaP/Gd-DTPA/DOX exhibited a higher longitudinal relaxivity (6.02?mM^?1?s^?1) than commercial MR contrast agent Gd-DTPA (3.3765?mM^?1?s^?1). The DOX release from the nanoparticles exhibited a pH dependent behavior. The cellular uptake results showed that the internalization of A54-CaP/Gd-DTPA/DOX into BEL-7402 cells was1.9-fold faster than that of HepG2 cells via A54 binding. In vivo experiments presented that A54-CaP/Gd-DTPA/DOX had higher distribution and longer retention time in tumor tissue than CaP/Gd-DTPA/DOX and free DOX, and also displayed great antitumor efficacy (95.38% tumor inhibition rate) and lower toxicity. Furthermore, the Gd-DTPA entrapped in the nanoparticles could provide T1-weighted MRI for real-time monitoring the progress of tumor treatment.
