Did you mean Promoter Region?

Glossary Promoter Region

specific DNA sequence where RNA polymerase binds to initiate transcription

The promoter region is a specific sequence of DNA located near the start of a gene that acts as a binding site for RNA polymerase and other transcription factors. This region essentially "promotes" the initiation of transcription, the process by which the genetic code from DNA is copied into messenger RNA (mRNA). Understanding promoter regions is crucial in fields like genetics and molecular biology, as they play a key role in regulating gene expression.

research Association between DNA Methylation in the Core Promoter Region of the CUT-like Homeobox 1 (CUX1) Gene and Lambskin Pattern in Hu Sheep

1 citations , September 2023 in “Genes”

This study found no significant difference in CUX1 core promoter methylation levels between different lambskin patterns in Hu sheep, suggesting other mechanisms influence CUX1 expression related to hair follicle development.

research Functional mapping of the mouse hairless gene promoter region

January 2018 in “bioRxiv (Cold Spring Harbor Laboratory)”

This study identified a new cis-regulatory element in the mouse Hr gene that influences its expression in skin and brain cells, highlighting a complex molecular network involved in hair follicle formation.

research Characterization of the Promoter Regions of Two Sheep Keratin-Associated Protein Genes for Hair Cortex-Specific Expression

14 citations , April 2016 in “PloS one”

This study found that the promoter region of the sheep KRTAP11-1 gene drives specific transcriptional activity in wool follicles, suggesting it may regulate hair keratinocyte specificity.

research The promoter of an androgen dependent gene in the hamster flank organ

6 citations , May 1997 in “Journal of Dermatological Science”

This study found that a gene from hamster flank organs is indirectly regulated by androgens, despite lacking direct androgen responsive elements, indicating involvement of androgen-dependent transcription factors.

research Regulation of Keratin Gene Expression in Hair Follicle Differentiation^a

98 citations , December 1991 in “Annals of the New York Academy of Sciences”

This study found that conserved DNA motifs and expression patterns in keratin genes suggest functional regulatory similarities in hair follicle differentiation across different mammalian species.

community Why does the same hormone grow your beard and destroy your hairline?

44 upvotes 4 months ago

DHT promotes beard growth but causes scalp hair loss due to inflammation and fibrosis. Treatments like finasteride and minoxidil help with hormonal signals and blood flow but don't address underlying inflammation.

community DIY treatment... Shedding completely stopped after 1.5 yrs

251 upvotes 4 years ago

Vitamin C mixed with shampoo stopped shedding and promoted hair regrowth after 1.5 years. Both the person and their wife experienced significant hair loss reduction with this method.

community Fats on your Head to Stop Hair Loss?

140 upvotes 2 years ago

The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.

community Prolactin the Cause of Hair Loss? ABS-201 the Cure?

29 upvotes 2 months ago

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.

community My Theory Of Androgenic Alopecia

16 upvotes 9 months ago

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
