Actions of NF-κB inhibitors on deoxycholyltaurine (DCT)-induced NF-κB nuclear translocation and transcriptional activation in H508 colon cancer cells
Inhibition, % reduction observed with inhibitor plus DCT (100 μM) | ||||
---|---|---|---|---|
Inhibitor | Nuclear translocation | p | Transcriptional activation | p |
SN50 (20 μg/ml) | 92.4±10.2 | 0.01 | 75.8±6.8 | 0.02 |
MG-132 (50 μM) | 85.4±8.7 | 0.01 | 82.7±7.3 | 0.02 |
BAY11-7082 (10 μM) | 70.9±6.4 | 0.02 | 60.4±6.1 | 0.03 |
H508 cells were incubated for 30 min with 100 μM DCT, alone or with the indicated concentration of NF-κB inhibitor, and nuclear extracts were immunoblotted for the p65 NF-κB subunit. NF-κB transcriptional activation was measured by using a TransAM NF-κB kit. Values are means±SE from three experiments. p indicates comparison of values observed with cells incubated with DCT (100 μM) plus the indicated concentration of NF-κB inhibitor compared to cells incubated with DCT alone.
