edited for use in hair loss and hair regrowth blog
Several families of proteins are expressed in the regrowth of hair. snip..Transgenic sheep over-expressing keratin genes but showing no hair growth change have been obtained and compared with the equivalent transgenic hair-loss mice. Studies of the effects of amino acid supply on the rate of hair regrowth have demonstrated that with cysteine supplementation of sheep a perturbation occurs in which there is a markedly increased level of only one type of mRNA and the ration of para- to orthocortical cells is increased. A molecular explanation of this phenomenon is being sought.
