Natural Chemical in Broccoli Helps to Prevent Skin Disease

The researchers treated newborn mice with a severe form of EBS—so bad they all died within three days—with a topical solution containing sulforaphane and found marked improvement; after four days more than 85 percent of the treated mice were alive and blister-free. These findings appear online this week in Proceedings of the National Academy of Sciences.
The basis of EBS, notes study author Pierre Coulombe, Ph.D., professor of biological chemistry, lies in two specific genes that make proteins known as keratins. Normally, the keratins join together and form highly resilient fibers in the lower portion of skin, helping make it durable. If either keratin is defective, they don’t mesh and the lower skin tissue becomes unusually fragile and gets damaged from the mildest mechanical stress — leading to blistering pain, a higher risk of infection, and in the most severe cases, death.
'Humans have around 54 distinct keratins, many of which are similar in structure and function,' says Coulombe. 'We figured we might be able to exploit this similarity and dial up a replacement by triggering the activation of a suitable signaling pathway in skin.' He predicted that sulforaphane might stimulate the formation of a surrogate skin-strengthening keratin to stand in for the defective one.
