Biological Activity


Targets Fluorogenic substrate
ln Vitro At 4 hours, there was a notable rise in caspase-3 activity in the Ac-DEVD-AFC group compared to the control after 1 hour. The Photofrin and LPLI groups did not exhibit a statistically significant elevation in caspase-3 activity. When caspase-3 is activated, the disruption of Ac-DEVD-AFC can be considerably reduced by transfecting shRNA-BiML [1].
To further confirm above observation, AFC (an indicator of caspase-3 activation) release assay was applied. Activated caspase-3 but not pro-caspase-3 does exert proteolytic activation on the Ac-DEVD-AFC substrate. As shown in Fig. 3E, after incubation with Ac-DEVD-AFC for 1 hour, significant increase of caspase-3 activity was observed at 4 hour after PPT (column 5) compared with control. There were no significant increases of caspase-3 activity in Photofrin and LPLI group (column 2 and 3). The cleavage of Ac-DEVD-AFC in response to caspase-3 activation was remarkably inhibited by shRNA-BimL transfection (column 6). These results demonstrated that Bim was involved in the PPT-induced caspase-3 activity, which was consistent with the result by western blot analysis [1].
Cell Assay Fluorometric assay for caspase-3 activity [1]
For the detection of caspase-3 activity, PBS washed cell pellets (derive from either the medium or the adherent cells) were resuspended in extract buffer [25 mM HEPES (pH7.4), 0.1% TritonX-l00, 10% glycerol, 5 mM DTT, 1mM phenylmethylsulfonyl fluoride, 10 mg/ml pepstatin, and 10 mg/ml Leupeptin] and vortexed vigorously. 20μl of extract (corresponding to 10% of the sample) were incubated with the caspase-3 fluorogenic substrates Ac-DEVD-AFC at 100 μM final concentration at room temperature, and caspase-3 activity was measured continuously by monitoring the release of fluorigenic AFC at 37°C. The excitation wavelength of AFC was 400 nm and the emission wavelength was 530 nm using auto microplate reader. As a parallel study to confirm and compare the caspase-3 detection in our experiments, batch of cells were exposed to UV irradiation, which a well-established protocol to induce apoptosis. For UV irradiation-induced apoptosis, culture medium was removed, and cells were rinsed with PBS and irradiated at fluence of 120 mJ/cm2 (253.7 nm, 200 μW/cm2), and then medium was restored.

Additional Infomation Background/aims: Photodynamic therapy (PDT) is a promising noninvasive technique, which has been successfully applied to the treatment of human cancers. Studies have shown that the Bcl-2 family proteins play important roles in PDT-induced apoptosis. However, whether Bcl-2-interacting mediator of cell death (Bim) is involved in photodynamic treatment remains unknown. In this study, we attempt to determine the effect of Bim on Photofrin photodynamic treatment (PPT)-induced apoptosis in human lung adenocarcinoma ASTC-a-1 cells.
Methods: The translocation of Bim/Bax of the cells were monitored by laser confocal scanning microscope. The levels of Bim protein and activated caspase-3 in cells were detected by western blot assay. Caspase-3 activities were measured by Caspase-3 Fluorogenic Substrate (Ac-DEVD-AFC) analysis. The induction of apoptosis was detected by Hoechst 33258 and PI staining as well as flow cytometry analysis. The effect of Bim on PPT-induced apoptosis was determined by RNAi.
Results: BimL translocated to mitochondria in response to PPT, similar to the downstream pro-apoptotic protein Bax activation. PPT increased the level of Bim and activated caspase-3 in cells and that knockdown of Bim by RNAi significantly protected against caspase-3 activity. PPT-induced apoptosis were suppressed in cells transfected with shRNA-Bim.
Conclusion: We demonstrated the involvement of Bim in PPT-induced apoptosis in human ASTC-a-1 lung adenocarcinoma cells and suggested that enhancing Bim activity might be a potential strategy for treating human cancers. [1]
