4、 (Ki) 12 nM (Ki)体外研究 To ascertain the role of caspase-3 in SLNT-induced apoptosis, a caspase-3 inhibitor (Ac-DEVD-CHO) isused. The addition of Ac-DEVD-CHO significantly prevents SLNT-induced apoptosis (from 32.911.21%decreases to 15.881.58% while NC and Ac-DEVD-CHO groups are 6.450.96%, 7.770.79%, r

5、espectively)2. The apoptosis rates of cells pretreated with zVAD-fmk (5.32%) or Ac-DEVD-CHO (7.43%) decreaseobviously after hypericin-mediated PDT treatment 3. Remarkably, 10 mol/L Ac-DEVD-CHO partially blocksthe effect of SIN-induced apoptosis and reduces the number of apoptotic nuclei. These effec

6、ts of SIN areblocked by the caspase-3 inhibitor Ac-DEVD-CHO. Camptothecin (4 M), a positive control, increasescaspase-3 activity, which is also blocked by Ac-DEVD-CHO 4.体内研究 Compare with model group, in CI group, the concentrations of serum BUN are decreased significantly at alltime points after ope

7、ration and those of Cr are decreased significantly at 6 hours, then restored to those ofthe sham group at 12 hours and 24 hours; the concentrations of serum TNF-, IL-6 are decreased and thoseof IL-10 are elevated significantly at all time points.

9、OTOCOLCell Assay 4 OCLs are incubated with RANKL and treated with 0.5 mM SIN with or without the specific caspase-3 inhibitorAc-DEVD-CHO (10 M) for 24 h. At the end of the treatment, the cells are washed with PBS and are stainedfor 15 min with 10 M Hoechst 33258 dye. Images of the staineing cells ar

TheAdministration 5 animals are assigned into three equal groups (n=34) according to random number table: sham group, modelgroup, and caspase-3 inhibitor (CI) group. Thirty minutes before CLP, Ac-DEVD-CHO (4 g/g) is injectedsubcutaneously in CI group.

12、 The levels of blood urea nitrogen (BUN) and creatinine (Cr) are determined, andthe concentrations of tumor necrosis factor- (TNF-), interleukins (IL-6 and IL-10) are measured by enzymelinked immunosorbent assay (ELISA), the renal cell apoptosis rate is determined by flow cytometry. The 4-day and 7-

13、day survival rates of three groups of mice are observed 5.MCE has not independently confirmed the accuracy of these methods.
