research Study of the keratinization process in human hair follicle by X-ray microdiffraction.

28 citations , July 2000 in “PubMed”

This study found no structural differences between in vitro and in vivo grown hair, with keratinization and organization of keratin being comparable in both settings.

research Cloning and Expression of Cellular Retinoic Acid Binding Protein I Gene in Inner Mongolian Cashmere Goats

1 citations , January 2012

In this study, the researchers cloned and analyzed the CRABP I gene in Inner Mongolian cashmere goats, finding its highest mRNA expression at 90 days in embryo skin compared to later stages.

Cloning, Computational Analysis and Expression Profiling of Steroid 5 Alpha-Reductase 1 (SRD5A1) Gene During Reproductive Phases and Ovatide Stimulation in Endangered Catfish, Clarias Magur

research Cloning, computational analysis and expression profiling of steroid 5 alpha-reductase 1 (SRD5A1) gene during reproductive phases and ovatide stimulation in endangered catfish, Clarias magur

November 2023 in “Scientific reports”

This study presents the first report on cloning and characterizing the full-length cDNA of SRD5A1 in Indian catfish (Clarias magur), revealing expression differences across reproductive phases and increased expression post-Ovatide administration in ovaries and testis.

research Plakophilin 1 suppresses keratinocyte innate immune responses through DExD/H helicases

August 2026

This study found that Plakophilin 1 regulates innate immune responses in keratinocytes by controlling RNA helicase activity, balancing inflammation during epidermal immune challenges.

research Effects on Steroid 5-Alpha Reductase Gene Expression of Thai Rice Bran Extracts and Molecular Dynamics Study on SRD5A2

14 citations , April 2021 in “Biology”

This study found that ethanol extract of Tubtim Chumphae rice bran downregulates SRD5A gene expression, similarly to finasteride, suggesting potential use as an anti-hair loss product.

community 17-alpha-estradiol/Alfatradiol how does it Work for Hair loss?

2 upvotes 1 year ago

17-alpha-estradiol may work for hair loss by inhibiting 5-alpha reductase, similar to finasteride. It might lower testosterone in the scalp, reducing DHT conversion.

community 5 alpha reductase type 1 is in brain tissue producing the main endogenous gabaergic allopregnanolone, not 2. How can finasteride as a 5ar2 lower that?

27 upvotes 1 year ago

Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.

community Mechanism of action of alfatradiol (17 alpha estradiol)

5 upvotes 2 years ago

The conversation discusses the mechanism of action of alfatradiol (17 alpha estradiol) in treating hair loss. It explores theories that it either inhibits 5 alpha reductase to prevent T->DHT conversion or aromatizes scalp T into 17-alpha-estradiol to save hair.

community Has there been any update or progress on the 3-alpha hydroxysteroid dehydrogenase hypothesis?

13 upvotes 2 months ago

The conversation discusses the hypothesis that a lack of the enzyme 3-alpha hydroxysteroid dehydrogenase (3α-HSD) on the scalp may contribute to hair loss by allowing DHT to accumulate. Despite interest in this theory, no recent research has been conducted, and current treatments like finasteride and minoxidil remain the most supported options.

community Which Saw Palmetto is good for blocking 5 alpha reductase, Serenoa repens or Chamaerops humilis?

6 years ago

The conversation is about determining which type of Saw Palmetto, either Chamaerops humilis or Serenoa repens, is effective for inhibiting the 5 alpha reductase enzyme related to hair loss. Specific treatments mentioned are Minoxidil, finasteride, and RU58841.
