Eating Broccoli Helps to Combat Genetic Skin Disorder
December 03, 2007 at 5:41 PM

The disorder in question is called epidermolysis bullosa simplex (EBS), which results from mutations in the genes encoding keratin 5 or keratin 14. The mildest form of EBS leads to blistering of the hands and feet since these are most susceptible to frequent abrasion.
Researchers led by Pierre Coulombe found that the compound sulforaphane whose natural precursors are found at high levels in broccoli and other cruciferous vegetables can help treat this disorder.
Sulforaphane has already been hailed for its chemopreventive powers against cancer.
Coulombe and colleagues turned to sulforaphane in their search for a chemical activator that would induce the production of missing keratins in basal epidermis.
There are 54 “conserved” keratin proteins in mammals -- meaning that evolution favoured their survival. Many of these keratins are closely related in their genetic sequences and their properties and by their distribution within epithelial tissues.
The researchers reasoned that such a situation breeds “functional redundancy,” meaning that the genetic loss of one keratin could be partially rescued by the overlapping functions of a keratin cousin.
Guided by prior evidence that partial redundancy was at work, the boffins used this as a basis for therapy in EBS.
