When cells were transfected with a plasmid expressing the p65 subunit of NF-kappaB, the inhibitory effect of sodium arsenite on NF-kappaB activity and IL-6 production was blunted.

A direct role of the NF-kappaB pathway in arsenic-induced apoptosis is shown by transient overexpression of NF-kappaB-p65 in L540Cy HRS cells, which protected the cells from arsenic-induced apoptosis.
