In this task, you are given a sentence. You are expected to recognize the name of gene or protein. Although there might be several correct answers, you need to write one of them.

Input: Consider Input: Similarly , A / R - induced E - selectin expression and neutrophil - endothelial cell adhesion were blocked by inhibition of PKC or PTK , while only PTK inhibited the redox - induced adhesion response .

Output: E - selectin

Input: Consider Input: NF - kappaB inhibition with N - acetylcysteine ameliorated the local inflammatory response .

Output: NF - kappaB

Input: Consider Input: ' ' Footprint ' ' and methylation - interference analyses have shown that purified NF - kappa B has a binding activity specific for the kappa light chain enhancer sequence .
Output: kappa light chain
