Knockdown of the gene for homeobox protein HOXB13 reduces toxicity of oxidative-stress inducers in HEK293 cells

Abstract

HEK293 cells transfected with a double-stranded siRNA to suppress expression of the homeobox gene HOXB13 were highly resistant to oxidative stress-inducing agents, such as hydrogen peroxide, N-ethylmaleimide (NEM), and paraquat. This finding suggests that HOXB13 might enhance cell injury caused by oxidative stress.
