research Steroid 5α-Reductase 2 Deficiency Leads to Reduced Dominance-Related and Impulse-Control Behaviors
Mice lacking steroid 5α-reductase 2 show less aggression and better impulse control.
research Bioprospecting of Potential Inhibitors of 5alpha Reductase 2 from Relevant Ethno-Pharmacological Plants via In Silico Techniques
Three natural compounds from Ghanaian plants may help treat BPH and alopecia.
research Discharge Guidance After Gastrectomy and Enterectomy - Using a Pamphlet -
The study utilized site-directed mutagenesis to explore the role of specific amino acid residues in human steroid 5alpha-reductase types 1 (5AR1) and 2 (5AR2) in inhibitor/substrate binding. It was found that replacing residues 21-24 in 5AR2 with those from 5AR1 did not significantly affect binding characteristics, while replacing residues 26-29 in 5AR1 with those from 5AR2 decreased the Km and increased resistance to Finasteride. This suggested that residues 26-29 in 5AR1 are crucial for binding, unlike residues 21-24 in 5AR2. Further experiments showed that residues 15-17 in 5AR2 are involved in binding, whereas residues 18-20 are not. These findings provided insights into the specific roles of amino acid residues in the binding process of these enzymes.

5 / 59 resultscommunity 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?
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 Connection between finasteride and nafld?
Finasteride may affect liver function and cortisol levels, potentially linking it to non-alcoholic fatty liver disease (NAFLD). More research is needed to understand this connection fully.
community How come dutasteride doesn't lower allopregnanolone, but finasteride does?
Finasteride significantly lowers allopregnanolone levels, while dutasteride's effect is less clear and may vary. Some users speculate that dutasteride might be healthier for the brain due to its different inhibition pathways.
community How finasteride lowers brain's happiness steroid allopregnanolone and causes depression: systemic dihydroprogesterone crosses blood brain barrier, you don't even need finasteride and brain 5ar for that
Finasteride may lower allopregnanolone levels, potentially affecting mood, but many users report improved mental health due to reduced hair loss. Experiences with finasteride and dutasteride vary, with some experiencing side effects and others finding them beneficial for hair retention and overall happiness.
community Finasteride only reduces scalp DHT by ~40%. Why does it work?
How Finasteride and Dutasteride help reduce hair loss by reducing the amount of DHT in scalp areas, as well as discussing factors such as sensitivity to DHT, 5α-reductase expression in different parts of the hair follicle, and scalp tension.
