    Ac-DEVD-CHO purchased from MCE. Usage Cited in: Apoptosis. 2019 Oct;24(9-10):703-717.  [Abstract]

    BMDMs were first primed with LPS (500 ng/ml) for 4 h, pre-treated with or without MCC950 (1 μM) and caspase-3 inhibitor Ac-DEVD-CHO (DEVD) for 1 h and followed by stimulation with ATP (5 mM) in the presence or absence of MCC950. The cell lysates are collected and western blotting is performed to assess the expression levels of indicated proteins.

    In Vitro

    To ascertain the role of caspase-3 in SLNT-induced apoptosis, a caspase-3 inhibitor (Ac-DEVD-CHO) is used. The addition of Ac-DEVD-CHO significantly prevents SLNT-induced apoptosis (from 32.91±1.21% decreases to 15.88±1.58% while NC and Ac-DEVD-CHO groups are 6.45±0.96%, 7.77±0.79%, respectively)[2]. The apoptosis rates of cells pretreated with zVAD-fmk (5.32%) or Ac-DEVD-CHO (7.43%) decrease obviously after hypericin-mediated PDT treatment[3]. Remarkably, 10 μmol/L Ac-DEVD-CHO partially blocks the effect of SIN-induced apoptosis and reduces the number of apoptotic nuclei. These effects of SIN are blocked by the caspase-3 inhibitor Ac-DEVD-CHO. Camptothecin (4 μM), a positive control, increases caspase-3 activity, which is also blocked by Ac-DEVD-CHO[4].

    In Vivo

    Compare with model group, in CI group, the concentrations of serum BUN are decreased significantly at all time points after operation and those of Cr are decreased significantly at 6 hours, then restored to those of the sham group at 12 hours and 24 hours; the concentrations of serum TNF-α, IL-6 are decreased and those of IL-10 are elevated significantly at all time points. [TNF-α (μg/L) 6 hours: 436.2±64.2 vs. 653.6±8.9, 12 hours: 233.4±85.4 vs. 579.7±137.1, 24 hours: 151.0±90.3 vs. 551.0±119.8, IL-6 (μg/L) 6 hours: 1033.2±345.8 vs. 1 595.3±159.4, 12 hours: 366.3±68.3 vs. 1 330.7±249.8, 24 hours: 241.2±208.4 vs. 815.3±572.7, IL-10 (μg/L) 6 hours: 33.6±10.4 vs. 26.6±4.5, 12 hours: 37.2±5.0 vs. 24.5±4.3, 24 hours: 38.3±5.5 vs. 18.2±1.6, all P<0.05]; the renal cell apoptosis rates are decreased significantly at all time points: apoptosis rates 6 hours: (13.9±3.2)% vs. (18.3±1.4)%, 12 hours: (10.5±3.6)% vs. (15.9±3.5)%, 24 hours: (8.4±1.8)% vs.(12.5±2.1)%[5].

    Cell Assay

    OCLs are incubated with RANKL and treated with 0.5 mM SIN with or without the specific caspase-3 inhibitor Ac-DEVD-CHO (10 μM) for 24 h. At the end of the treatment, the cells are washed with PBS and are stained for 15 min with 10 μM Hoechst 33258 dye. Images of the staineing cells are captured with a fluorescent microscope. The differences are evaluated by counting the number of cells with apoptotic nuclear condensation in each well[4].

    Animal Administration

    One hundred and two male mice are subjected to cecal ligation and puncture or sham operation. The animals are assigned into three equal groups (n=34) according to random number table: sham group, model group, and caspase-3 inhibitor (CI) group. Thirty minutes before CLP, Ac-DEVD-CHO (4 μg/g) is injected subcutaneously in CI group. The levels of blood urea nitrogen (BUN) and creatinine (Cr) are determined, and the concentrations of tumor necrosis factor-α (TNF-α), interleukins (IL-6 and IL-10) are measured by enzyme linked immunosorbent assay (ELISA), the renal cell apoptosis rate is determined by flow cytometry. The 4-day and 7-day survival rates of three groups of mice are observed[5].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
