PI3K-Akt signaling pathway thermogenesis ECM-receptor interaction IGF1 IGF1R FGF5 keratin-related genes secondary hair follicle development

TLDR Differences in cashmere quality between goat breeds are linked to specific genes affecting hair follicle development.

This study investigated the molecular mechanisms responsible for differences in cashmere quality between Jiangnan cashmere goats (JNCG) and Changthangi pashmina goats (CPG) by analyzing skin transcriptomic data from different hair follicle growth stages. A total of 4,942 differentially expressed genes (DEGs) were identified, with significant enrichment in the PI3K-Akt signaling pathway, thermogenesis, and ECM-receptor interaction. Key candidate genes such as IFG1, IGF1R, FGF5, and several keratin-related genes were highlighted for their roles in secondary hair follicle development and cashmere quality. These findings provide a theoretical basis for the genetic improvement of cashmere goats.

community Does melatonin dissolve in isopropyl alcohol

in Technology 8 upvotes 2 years ago

The conversation discusses making a topical melatonin solution for hair loss treatment, questioning if isopropyl alcohol can dissolve melatonin. Melatonin is soluble in lipids and alcohol, but it's unstable and should be mixed fresh regularly; it may help hair growth by affecting certain cellular signaling pathways and has anti-androgenic effects.

community New Research- Creatine Increasing Scalp DHT Without Corresponding Serum DHT Increase

in Research/Science 123 upvotes 1 year ago

Creatine may increase scalp DHT without affecting serum DHT, potentially speeding up male pattern baldness (MPB) for those genetically prone. Treatments mentioned include Minoxidil, finasteride, and RU58841.

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

community The Real Cause Of Androgenetic Alopecia

in Research/Science 676 upvotes 1 year ago

Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.
