Gene Research Gives Hope of Reversing Baldness 216

Hair loss in humans might not be irreversible, suggest scientists who have helped create new hair cells on the skin of mice. It was thought hair follicles, once damaged, could never be replaced. A University of Pennsylvania team, writing in the journal Nature, say hair growth can actually be encouraged using a single gene.

    • Getting rid of excess hair is easy and relatively cheap. A girlfriend and I had planned on getting it done - her for her legs and me for my back. Adding hair back to the crown of my head (getting close to the point I'm going to have the chop off the several feet of hair I have to avoid having the "loser living in his mom's basement" skull-crown look) is significantly more painful and costly. The only real treatments long-term now involve grafts or artificial implants.

          It's several multiples of a thousand dollars. The exact price depends on where you go. The average when I researched it seemed to be about US$4000. However, IMO the results are pretty poor - most of the "after" pictures I saw looked like the guy still had noticeably thinning hair instead of a completely bald spot.

      Actually, it doesn't.

      If you're lucky, Rogaine (minoxidil) will help you keep the hair you have, and maybe grow a little hair back (not to mention, grow hair -on- your back, because the drug is absorbed systemically).

      It also tends to work only on your bald spot. Receding hairlines do not suddenly un-recede (proceed?).

      Also, what grows back tends to be a thin and sickly kind of hair. That is because, at the cellular level, baldness is actually an inflammatory condition, and while Rogaine addresses the symptoms of arrested hair growth, it does nothing to cure the underlying disease process, for which no effective treatment exists currently.

      In a nutshell, Rogaine tricks dying hair follicles into sputtering out a little more mane, but they're still dying at the root.

      And (the best part), if it works at all, it's good only as long as you use it religiously. Lapse, and what hair you were maintaining with the drug, promptly falls out within a few months.

      The follicle inflammatory response in baldness seems to be triggered by genetic sensitivity to a metabolite of male hormones (androgens). The other drug you've probably heard about, Propecia, attempts to block these sensitive androgen receptors, whose activation by the metabolite precipitates the inflammation. But it too is imperfect and rife with the potential for sexual side effects, no matter what the literature says.

      Rogaine, like so many other medicines, is a crude, high-cost, brute-force fix to a complex, genetically predisposed condition, so perhaps a genetic fix is the best hope.

    Am I the only one that doesn't have a problem about going bald? Or having some deep complex about body hair in general?

    It's not hair or lack of it that makes people look good or bad. You tend to lose it during your early middle age, and frankly it's not the hair situation which makes you look over the hill. If you're like most Western guys it's things like your hanging belly, heavy jowls and plushy, coarse, unkempt complexion that makes you look old and pathetic, not the follicle density of your skull top. You could have a mane big enough to play in a hair band and you'd still look old and pathetic.

        "The ladies" - like every woman (like every man) would have the same taste or the same priorities? Perhaps it's being the kind of person that calls women "the ladies" that pushes them off?

        Again, for most middle-aged people it's not the hair, it's the habitual Nixon-after-a-bender look that's the basic problem.

      Exactly. Going bald is not something that people would chose if they could avoid it, but it's not the great drama some people make of it. You touch a very important point: going bald is bad when everything else in you is not that good either. I'm not talking about being "pretty", but being *fit*. That makes a world of difference, whereas hair is more or less secondary if everything else is in a decent shape.

        This is untrue. While it's true that most people don't care about baldness in other people, a great deal of people *DO* care about baldness in themselves. Why? One word. Vanity.

        Vanity may not be particularly logical or practical or even seem worthy of recognition to some, but it is a simple fact that it is part and parcel of the human condition. A real and lasting cure for baldness would make its inventors very rich very quickly.

    Funny thing though. In this week's Nature there is this article [nature.com] where American scientists speculate on an alternative method to promote de novo follicle growth [in mice] via... grazing of the scalp.

    I quote the scoop from the New Scientist's entry:
    Could a graze on the head help cure baldness? Biologists had thought that once mammals lose their hair follicles, they are gone forever. Now George Cotsarelis at the University of Pennsylvania in Philadelphia and his colleagues have shown that adult mice can regenerate follicles when their skin is wounded.

    The team cut out a square centimetre of skin from the backs of mice two weeks after their hair follicles had formed. After 14 to 19 days the wounds had closed and formed new. When the researchers added Wnt proteins - signalling molecules usually involved in embryonic development - the number of follicles doubled and the skin healed with less scarring. This suggests that wound healing may trigger an embryonic state in skin, says Cotsarelis. Surprisingly, the new follicles originate from stem cells that are not usually involved in creating hair follicles.

    Cotsarelis hopes the findings could lead to new therapies for baldness. "The idea would be to disrupt the skin to trigger the embryonic pathways, and then come in with the Wnt proteins," he says.

    First, as usual, missing ref to orig article in Nature [nature.com]. Now to the article:

    hair growth can actually be encouraged using a single gene.
    If you look at corresponding KEGG entry [genome.jp] for gene Wnt10b that was expressed in regenerated follicles you will find that besides Wnt signalling pathway [genome.jp][PIC!] (also here [wikipedia.org]) mentioned in the paper. this particular gene is also involved in Basal cell carcinoma [genome.jp] pathway.

    Both pathways are cancer-related and the first one is fairly complex, so there will be (hopefully) a lot of (lengthy) research intended to find out possible side effects.
