چکیده انگلیسی
NF-κB activity is tightly regulated by IκB class of proteins. IκB proteins possess ankyrin repeats for binding to and inhibiting NF-κB. The regulatory protein, NPR1 from Brassica juncea possesses ankyrin repeats with sequence similarity to IκBα subgroup. Therefore, we examined whether stably expressed BjNPR1 could function as IκB in inhibiting NF-κB in human glioblastoma cell lines. We observed that BjNPR1 bound to NF-κB and inhibited its nuclear translocation. Further, BjNPR1 expression down-regulated the NF-κB target genes iNOS, Cox-2, c-Myc and cyclin D1 and reduced the proliferation rate of U373 cells. Finally, BjNPR1 decreased the levels of pERK, pJNK and PKCα and increased the Caspase-3 and Caspase-8 activities. These results suggested that inhibition of NF-κB activation by BjNPR1 can be a promising therapy in NF-κB dependent pathologies.
