But the 2016 study now reveals the possiblity of other similar AGA-causative genes affecting multi-ethnic groups. For your info, the study also ruled out EDAR's invovlement and stated that AR is the sole causative gene in that region. But what we do know is that the AR gene is not an AGA-causative 1 in East asians.

    There is no defnite answer on il-6, especially when it's a https://en.wikipedia.org/wiki/Treg17_cells cytokine utilising the STAT3 pathway- and http://www.pnas.org/content/97/25/13824.full.pdf is critically involved in hair growth. U might be right, though- in a sense that there are 2 possible scenarios regarding IL-6:

    1)There is atually an underexpression of STAT3/Th17 responses in the balding scalp , being replaced by TH1/Th2 cytokine responses instead- resulting in the upregulation of 'bad' inflammation genes in the context of hair growth.
    2)There really is an overexpression(like what u think) of STAT3/Th17.
    Ya I think you misinterpreted what I said, I am in agreeance with you. Other regions are involved for Asians besides 20p11, but the region on chromosome x effecting the Ar isn't one of them, and 20p11 is the single strongest at risk region. In fact amongst Europeans, there are 3 different spots between foxa2 and pax1 that are at risk points for AGA. There are only 2 at risk spots between eda2r and Ar (although the single highest at risk SNP is one of these nucleotide variants at one of those spots). Ago
    Again the fact that Ar obviously has to do with androgen metabolism and foxa2 does as well fits the phenotype. Some other big spots are HDAC9 and HDAC4 (amongst many others). HDAC4 has been shown in some cell types to aid in Ar gene suppression so perhaps a certain variant in AGA doesn't allow this process to happen as effectively.

    Ok, so for your info once again, the 2016 study also ruled out both HDAC4 and HDAC9 as AGA-causative genes. Instead, PER2 and TWIST2 in HDAC4's region were the true AGA-causative genes found to be downregulated in balding scalps.

    TWIST1 in HDAC9's region was found to be the true AGA-causative gene- upregulated in balding scalps.

    Unsurprisingly, PER2 and TWIST2 is upregulated by Estradiol and Genistein while TWIST1 is downregulated by estrogenic compounds

    It's unlikely that both Hnf4a and Foxa2 would be involved in DPC differentiation because expression of those two together turns fibroblasts into hepatocytes. However, even if only one of them is involved, you would likely find that both show up in this sort of analysis because their target genes overlap, and of course we do see that.

    SOX2 is mainly invovled with the shape of the individual hair follicle:
    I haven't yet looked into Sox2 that carefully, but it's also possible that it's not upregulated or downregulated, but could instead be regulated "differently" due to binding by co-factors.

    Great job Inbeforethecure. You bring up an EXCELLENT point with pioneer factors. I have wondered this myself about 20p11. And in my opinion that is the number one enemy overall. It is the the region linked to AGA the strongest if all ethnicities are considered (Ar-Eda2r is monomorphic in Asian AGA). Upon reading on the two associates genes between the potential SNP's at 20p11 it would seem as if FOXA2, not PAX1 is the one that should be implicated. Foxa2 is know to be an androgen metabolic regulator, and another one of its many functions is response to interleukin 6, which has already been shown to be released in response to DHT in AGA DP and cause Catagen of actively growing follicle. So it really confounded me as to why foxa2 isn't expressed in AGA scalp (not in dp or in the rest of the hair follicle itself) but pax1 is. This seems to fit and clear that up. Awesome job. I really enjoy reading your computer data breakdowns as well.
    Thank you. Actually though, I don't think it's cleared up at all. Pioneer factors are usually actively expressed in the cells they regulate AFAIK, so this would have to be some form of epigenetic memory if anything. As for IL6 and other inflammatory cytokines, I think it would be most natural to blame stress-induced p38 MAPK activity.

    p38 and inflammation

    A strong link has been established between the p38 pathway and inflammation. Rheumatoid arthritis, Alzheimer's disease and inflammatory bowel disease are all postulated to be regulated in part by the p38 pathway 87, 88, 89. The activation of the p38 pathway plays essential roles in the production of proinflammatory cytokines (IL-1beta, TNF-alpha and IL-6) 90; induction of enzymes such as COX-2 which controls connective tissue remodeling in pathological conditions 91; expression of intracellular enzymes such as iNOS, a regulator of oxidation 92, 93; induction of VCAM-1 and other adherent proteins along with other inflammatory related molecules 18. In addition, a regulatory role for p38 in the proliferation and differentiation of immune system cells such as GM-CSF, EPO, CSF and CD-40 has been established 16, 94.

    Chemical found the cure, but unfortunately the international conspiracy of hair transplant surgeons and minox vendors got to him. If he talks, he's a dead man. That's why he's disappeared.

    I do not know yet if Foxa2 is upregulated or downregulated in AGA individuals, not just necessarily in the scalp itself- but possibly in the organs that are vital to the scalp's functioning. (e.g thyroid, parathyroid, thymus- all of which Pax1 itself is heavily expressed in).

    But what i do know from studies is that knockout of FOXa2 switches the response to TH2 cytokines- and this is the group of that is responsible for 'AGA itch' and is contained in sebocytes. So i will assume that FOXA2 is downregulated in AGA individuals. i might be wrong though.
    Foxa2, if it's involved, would most likely confer risk to AGA by acting as a pioneer factor at AR target genes IMO. That's something it's known for.

    Those SNPs are in high linkage disequilibrium with each other, so you would need a massive sample size to discern multiple risk points.

    Focusing on the 5 SNP model from this study:



    Best guesses for the functional variants at these sites: AR, PAX1 or FOXA2, RNF145, MTOR, TWIST1?

    this 5ar research on ganoderma lucidum from 2007 is interesting, for guys in particular. reishi is easy to find / inexpensive:

    The anti-androgen effect of ganoderol B isolated from the fruiting body of Ganoderma lucidum

    I was able to search on the paper title and found a free pdf eventually, can't find the link now...
