I'm cookin' up one hell of theory...
Dare I propose that Androgenetic Alopecia is merely a manifestation of oxidative susceptability syndrome? I read an article where non-balding DPCs went into apoptosis in the presence of androgens but large amounts of androgens were needed. What does mean? To me it means that either there's a factor in place protecting healthy follicles from androgen-induced apoptosis that wasn't able to protect the DPCs in the petri dish, or, there's another mechansim by which apoptosis occurs. Personally, I believe that this androgen-mediated negative feedback is enough to initiate an oxidative sequence where p53 is upregulated, causing premature senescence and apoptosis, explaining the study I read where balding subjects were found to have elevated p53 levels and also have the presence of DNA "repair enzymes" (which may confirm my theory of oxidative damage). I'm not sure if I think we have elevated p53 levels in general... or maybe an anti-oxidant insufficiency?
I'm not at my computer so I will have to post my references later but here's some stuff off the top of my head:
- It's been suggested that oxiative stress may be the real culprit behind metabolic syndrome. p53 appears to be a stronger correlation between Androgenetic Alopecia and metabolic syndrome than insulin sensitivity ever was, in my opinion.
- cyclosporin appears to inhibit p53. This may help explain it's hair growth effects.
- Why do we see a regressive thinning of the hair shaft in male pattern baldness? I've been wondering if maybe... just maybe... it takes a certain number of cells to form a hair shaft of certain thickness? Who knows... maybe as time goes on - and more and more cells succomb to oxidative stress - the number of viable cells diminishes and instead of having "x" amount of cells to create a hair with "y" diameter, we now are left with half of what we originally had, resulting in a hair shaft with half the diameter? Long shot, I know...
Feel free to step in and tell me that I sound retarded. But you heard it here first, folks.... betcha' oxidative stress and p53-induced senescence and apoptosis is more of an enemy than the proverbial boogey man DHT.
