Effects of IkappaBalpha and its mutants on NF-kappaB and p53 signaling pathways.

ABSTRACT:

Aim

To study the effects of IkappaBalpha and its mutants (IkappaBalphaM, IkappaBalpha243N, IkappaBalphaM244C) on NF-kappaB, p53 and their downstream target genes. The relationship of NF-kappaB, p53, and IkappaBalpha was further discussed.

Methods

pECFP-IkappaBalpha, pECFP-IkappaBalphaM (amino acides 1-317, Ser32, 36A), pECFP-IkappaBalpha243N (amino acides 1-243), pECFP-IkappaBalpha244C (amino acides 244-317), pEYFP-p65 and pp53-DsRed were constructed and transfected to ASTC-alpha-1 cells. Cells were transfected with pECFP-C1 as a control. 30 h after the transfection, location patterns of NF-kappaB, p53 and IkappaBalpha (IkappaBalphaM, IkappaBalpha243N, IkappaBalpha244C) were observed by a laser scanning microscope (LSM510/ConfoCor2, Zeiss).
