The NEMO (NF-KB Essential Modulator) Binding Domain (NBD) peptide induces apoptosis in several melan


ABSTRACT: The transcription factor NF-kB is an important regulator of genes involved in inflammation and cell proliferation. Several studies previously showed that NF-kB transcription factor was constitutively activated in melanoma cell lines due to the up regulated activity of inhibitor of NF-kB kinases (IKK). In the present study, we tested the activation of NF-kB pathway following TNF stimulation in 9 melanoma cell lines and the subsequent inhibition after the treatment of a small–molecule IKK inhibitor NDB peptide using Secreated Alkaline Phosphate (SEAP) reporter gene assay. The pro-apoptotic effects induced by NBD peptide treatment were determined by flow cytometry as well as by Western Blot testing of PARP’s cleavage. Our findings showed that NBD peptide was able to block IKK-NFKB pathway in all tested cell lines by inducing apoptosis as confirmed by increased levels of active caspase 3 and PARP cleavage after treatment. Moreover, our finding provides the basis for the development of a novel therapeutic approach targeting NF-kB transcription factor to treat melanoma.
