Genetic Analysis of 5 Alpha Reductase Type 2 Enzyme in Relation to Oxidative Stress in Cases of Androgenetic Alopecia in a Sample of Egyptian Population

research Genetic analysis of 5 α reductase type 2 enzyme in relation to oxidative stress in cases of androgenetic alopecia in a sample of egyptian population

1 citations , October 2013 in “Our Dermatology Online”

This study found that individuals in this Egyptian cohort carrying the leucine (L) allele of the 5-α reductase type II enzyme had a higher risk of developing androgenetic alopecia, which may be associated with oxidative stress.

research Analysis of genetic polymorphisms of steroid 5α-reductase type 1 and 2 genes in Korean men with androgenetic alopecia

15 citations , April 2003 in “Journal of Dermatological Science”

This study found no significant associations between the polymorphisms of SRD5A1 and SRD5A2 genes and androgenetic alopecia, clinical types of baldness, or response to finasteride in Koreans.

research Enzymology of the hair follicle.

31 citations , August 2001 in “PubMed”

This review discusses the role of androgen metabolism in hair follicles and its potential impact on future treatments for androgenetic alopecia, but reports no clinical results.

Human Type 3 5α-Reductase Is Expressed in Peripheral Tissues at Higher Levels Than Types 1 and 2 and Its Activity Is Potently Inhibited by Finasteride and Dutasteride

research Human type 3 5α-reductase is expressed in peripheral tissues at higher levels than types 1 and 2 and its activity is potently inhibited by finasteride and dutasteride

45 citations , August 2010 in “Hormone Molecular Biology and Clinical Investigation”

This study found that SRD5a-3 is a highly efficient enzyme for converting hormones into androgens, with dutasteride being a much more potent inhibitor of SRD5a-3 than SRD5a-2.

research Steroid 5α-reductases and 3α-hydroxysteroid dehydrogenases: key enzymes in androgen metabolism

115 citations , March 2001 in “Baillière's best practice and research in clinical endocrinology and metabolism/Baillière's best practice & research. Clinical endocrinology & metabolism”

This article reviews how different 5alpha-reductase and 3alpha-HSD enzymes impact androgen levels and highlights their potential as drug targets for androgen-related diseases, but provides no new experimental findings.

community Did anybody use beta sisterol for hair loss? I saw in many articles in the internet that said that beta sisterol blocks dht by inhibiting 5a reductase type 2 enzyme and some reviews of people who said that it worked better than saw palmetto in terms of stoping hair loss and helping prostate.

in Research/Science 9 upvotes 3 years ago

Beta-sitosterol may inhibit 5-alpha reductase type 2 enzyme, potentially reducing DHT levels and promoting hair growth, similar to finasteride but possibly with fewer side effects. Its effectiveness and side effects compared to other treatments like saw palmetto and finasteride remain uncertain due to limited research.

community Was scared to try fin and jumped straight to 2.5mg Dut?

36 upvotes 4 days ago

The user started with oral minoxidil and switched to 2.5mg dutasteride, experiencing significant hair growth without side effects. They believe dutasteride has fewer side effects than finasteride due to its action on both type 1 and 2 5-alpha reductase enzymes.

community Interesting new publication suggesting that MPB should be assessed as a early warning sign for type-2 diabetes.

15 upvotes 8 years ago

Male pattern baldness (MPB) may be an early warning sign for type 2 diabetes due to its association with insulin resistance. Treatments discussed include testosterone therapy and finasteride, which affects hormone levels related to hair loss and insulin sensitivity.

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 Isn't it kind of strange that hair loss happens at where the 2 main superficial temporal arterty branches (temples and crown) are?

5 upvotes 3 years ago

Hair loss may be linked to blood flow and inflammation, with treatments like Minoxidil, finasteride, and quercetin being discussed. The conversation also mentions the role of 5AR enzyme distribution in hair follicles.
