Hair follicles undergo continuous cycles of growth, involution and rest. (aging-us.com)
At the same time, skin and hair follicles harbor a functional circadian clock that regulates gene expression with a periodicity of approximately twenty four hours. (aging-us.com)
In mice, the two initial hair growth cycles are synchronized such that the majority of hair follicles are in a similar stage of the hair growth cycle at a given time. (aging-us.com)
Since our mRNA expression studies were performed using whole skin, we asked which compartments of the skin and hair follicles contribute to the robust rhythmic circadian gene expression in telogen. (aging-us.com)
Scientists have long known that greying is the result of a gradual disappearance of melanin in hair follicles - melanin is the protein responsible for giving hair its color. (time.com)
We might have drugs that boost or stop the protein from acting and change the amount of melanin in hair follicles and change the hair internally," says Adhikari. (time.com)
While in some cases, hair loss is caused by external factors such as exposure to UV, smoking or strain on the follicles (traction alopecia), other cases are mostly influenced by genes. (hairtransplantdelhi.org)

London: Researchers have identified rare gene variants that cause male pattern hair loss, also termed androgenetic alopecia. (gulfnews.com)
To date, studies worldwide have focused primarily on common genetic variants, and have implicated more than 350 genetic loci, in particular the androgen receptor gene, which is located on the maternally inherited X chromosome. (gulfnews.com)
Within this extensive data set, Bonn geneticists examined rare gene variants that occur in less than one per cent of the population. (gulfnews.com)
Using modern bioinformatic and statistical methods, they found associations between male-pattern hair loss and rare genetic variants in the following five genes: EDA2R, WNT10A, HEPH, CEPT1, and EIF3F. (gulfnews.com)
Prior to the analyses, EDA2R and WNT10A were already considered candidate genes, based on previous analyses of common variants. (gulfnews.com)
Our study provides further evidence that these two genes play a role, and that this occurs through both common and rare variants," explained Dr. Stefanie Heilmann-Heimbach, who is a research group leader at the Institute of Human Genetics. (gulfnews.com)
Similarly, HEPH is located in a genetic region that has already been implicated by common variants, namely the EDA2R/Androgen receptor, which is a region that has consistently shown the strongest association with male-pattern hair loss in past association studies. (gulfnews.com)
They are thus entirely new candidate genes, and we hypothesise that rare variants within these genes contribute to the genetic predisposition. (gulfnews.com)

One of the surprises that came from this study was the finding that genes regulated by the core circadian clock mechanism showed expression changes that correlated with the hair growth cycle, with highest expression during the telogen-anagen transition. (aging-us.com)

While these genes show a clear circadian pattern of expression in skin, as was previously demonstrated [ 9 - 11 ], their amplitude was higher during telogen and early anagen (Figure 1 ), indicating that in skin, the expression of clock controlled genes is dependent both on circadian mechanism and the hair growth cycle.
