androgen receptor androgenetic alopecia GGN repeats SNP rs9332969 rs9332970 male pattern baldness

TLDR Shorter GGN repeats in the androgen receptor gene are linked to androgenetic alopecia.

The study investigated the association between androgen receptor polymorphisms and androgenetic alopecia in 43 affected males and 27 controls. It found that the length of GGN repeats in the androgen receptor gene was correlated with androgenetic alopecia, with repeats of ≤23 being highly associated with the condition. However, no polymorphisms were found in the SNPs rs9332969 and rs9332970 among the Chinese participants, which differed significantly from the 50% occurrence reported in GENBANK of NCBI.

community Proposed new pathogenesis model for androgenetic alopecia (AGA)

in Research/Science 8 upvotes 2 years ago

The conversation discusses a new model for understanding androgenetic alopecia (AGA), linking it to dietary and lifestyle factors similar to PCOS, and highlighting the role of DHT, vascular damage, and inflammation. Treatments mentioned include Minoxidil, finasteride, and RU58841.

community Eliminate/Confirm AGA based on blood report

in General 126 upvotes 9 months ago

A 19-year-old male with no family history of androgenetic alopecia (AGA) is experiencing hair loss and considering using a topical minoxidil and finasteride mixture. Despite low vitamin D levels and normal DHT serum levels, he seeks confirmation of AGA before starting treatment.

community End of Hair loss ( AGA ) ? Since they produce it in china probably we don’t need to wait other 10 yrs😁

in Treatment 271 upvotes 2 weeks ago

GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.

community What is preventing GT20029 from being the cure to androgenetic hair loss?

in Research/Science 9 upvotes 7 months ago

GT20029 is discussed as a potential treatment for androgenetic hair loss by targeting androgen receptors, unlike finasteride which reduces DHT broadly. Concerns include its effectiveness, genetic variations in androgen receptors, and availability, with some skepticism about its potential as a true alternative.

community Can amino acids help with AGA

in Chat 3 upvotes 1 year ago

Amino acids like lysine, methionine, and cysteine may help with androgenetic alopecia when taken in high doses along with a DHT blocker. Users discuss combining these with treatments like Minoxidil, finasteride, and RU58841.

community Evolution theory: AGA is your body trying to reduce the risk of prostate cancer by exposing your scalp to more UV

in Research/Science 3 months ago

Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.
