New Research Pins Baldness To a Single Chemical (independent.co.uk) 71

An anonymous reader quotes a report from The Independent: A single chemical could be responsible for whether people go bald or not, a new study has found. In the UK, approximately two thirds of men will face male pattern baldness. The study says the discovery of the chemical could "not only treat baldness, but ultimately speed wound healing." In the study published in the Biophysical Journal, study co-author Qixuan Wang said: "In science fiction when characters heal quickly from injuries, the idea is that stem cells allowed it. In real life, our new research gets us closer to understanding stem cell behavior, so that we can control it and promote wound healing."

The team looked at hair follicles as these are the only human organ that regenerates regularly and automatically, and discovered that a type of protein called TGF-beta controls how the stem cells in hair follicles divide and why some can die off. Wang explained: "TGF-beta has two opposite roles. It helps activate some hair follicle cells to produce new life, and later, it helps orchestrate apoptosis, the process of cell death. Even when a hair follicle kills itself, it never kills its stem cell reservoir. When the surviving stem cells receive the signal to regenerate, they divide, make new cell and develop into a new follicle." However, the scientists found that when a hair follicle dies, the stem cell reservoir still remains. "When the surviving stem cells receive the signal to regenerate, they divide, make new cells and develop into a new follicle," Wang said. The study authors added that it may be possible to stimulate hair growth by activating follicle stem cells, but more research on the subject needs to be done.

    If you can turn hair follicles on, you can turn them off. I imagine having a jar of each type of cream would become mandatory in every bathroom medicine cabinet.

    Imagine, a perfect shave until you decide you want to try a goatee or something.

        Tell her you're legally obligated to conform to your Slashdot username.

        Before I ever grew a beard (and wasn't sure I even could), my wife told me she hated beards. Then when I went to do some really remote fieldwork (decades ago), I decided I wanted to try - and she said "okay I want to see it but then I want you to shave it off". But when I came back with it, she told me she wanted me to keep it - and now, when I do shave, she asks me when I'll be growing my beard back.

        Maybe the bottom line is... she doesn't like my face?

      Yes. Of course. That is exactly what I was thinking. Use it to sculpt one's facial hair.

    The summary is contradictory. Do they make new cell or make new cells?

      Yup, Slashdot is badly edited. What a shock.

      I wonder if the poster read the post before posting. Having said that I suppose it's "make new cells" because it makes sense, but one of these sentences is too much. The way I see it, what it should have looked like is only "When the surviving stem cells receive the signal to regenerate, they divide, make new cells and develop into a new follicle," Especially having "however" in front is confusing.

  • Here we have an ordinary post:

    Wang explained: "TGF-beta has two opposite roles .... When the surviving stem cells receive the signal to regenerate, they divide, make new cell and develop into a new follicle."

    Now, at this point, the text follicle has died. But if we apply a little TGF-beta:

    "When the surviving stem cells receive the signal to regenerate, they divide, make new cells and develop into a new follicle," Wang said.

    See? iThe quote is good as new.

    Works for entire postings as well. Just give them a

  • I believe it's generally extremely important that cells respect signaling pathways that lead to apoptosis. Those that don't are often forms of cancer.

    • Didn't make it through the summary, then? Nobody's looking at preventing the death of the follicle, but rather how to get the stem cells to create a new one.

      That said, the apoptosis is triggered by exposure to a form of testosterone. Which also happens elsewhere in the body, not just follicles. There are probably a lot of age-related conditions that could be treated by understanding more about this. But I don't understand a lot about it - since these are all age related things where testosterone levels

  • Male baldness is a relatively recent development evolution-wise. It seems there is/was strong selection pressure for it for unknown reasons. One hypothesis is that it reduced flea problems for older males, as living in populated areas spread a lot of flea-born illness, and as you get older, your immune system declines.

    Everybody has injuries during their life. From small scrapes and bruises to serious injuries.

    As a side effect of something to decrease boldness.
    And it is described as 'to treat boldness'. Srsly? Treat? Since when is this is a disease? Why should be even want to treat it?

    Microcompetition with Foreign DNA and the Origin of Chronic Disease. August 2003. ISBN: 0-9740463-0-2 Authors: Hanan Polansky
    The cause of many of the chronic diseases such as cancer, atherosclerosis, obesity, diabetes, osteoarthritis, multiple sclerosis, is unknown. Therefore, current medications, if available, treat symptoms rather than cause. Under such conditions, recovery and prevention are unattainable. Recently, Dr. Hanan Polansky discovered that the cause of these diseases is an infection with a latent, or "dormant" virus. The current paradigm holds that viral proteins are the only creators of the viral effect on host cell, in other words "no viral protein, no effect." A latent virus either does not produce viral proteins, or produces a limited number of proteins. Following such paradigm, scientists assume that a latent infection is harmless. Dr. Polansky discovered a direct effect of viral DNA on cellular gene expression. As it turns out, this effect modifies gene expression, which alters cell function. Over an extended period, the abnormal cell function manifests itself as the symptoms associated with many chronic diseases. This effect underlies the Microcompetition Model, first described in this book. The significance of the Microcompetition Model cannot be overstated. From a health perspective, the discovery of the cause of these chronic diseases opens the door to discovery of medications, that for the first time in history treat the cause of the disease rather than symptoms, and therefore, for patients offer complete recovery, and for the public, protection against the disease.

    The GABPp300 transcription complex normally suppresses both5reductase and AR expression. Therefore, microcompetition between these genes and a latent virus, which also binds the complex, reduces the suppression and causes overexpression of 5re-ductase and AR The excess 5reductase increases the conversion oftestosterone into DHT, which binds to excess AR, culminating in the development of MPB.
