Glossary Signaling Pathways

series of molecular interactions transmitting signals within cells

Signaling pathways, also known as signal transduction pathways or cell signaling pathways, are a series of molecular interactions that transmit signals from a cell's exterior to its interior, leading to a specific cellular response. These pathways involve receptors, enzymes, and other proteins that work together to regulate various biological processes, such as cell growth, differentiation, and apoptosis. Understanding these pathways is crucial for developing treatments for conditions like cancer and alopecia, where signaling disruptions can lead to disease.

6 upvotes 3 years ago

Mango oil may inhibit DKK1 and DHT, potentially aiding hair growth by activating the Wnt signaling pathway. A user plans to test mango leaves juice and other Ayurvedic products for hair regrowth.

community Tazarotene shows strong standalone hair regrowth potential, not just a Minoxidil enhancer. Backed by VEGF, HF regeneration, and angiogenesis pathways. Here’s why.

135 upvotes 1 year ago

Tazarotene shows potential as a standalone treatment for hair regrowth by stimulating new hair follicle formation and promoting angiogenesis, similar to microneedling effects. It can be used topically without minoxidil, but users should start with a low concentration to avoid irritation.

community I had claude create a protocol only using fda approved drugs.

4 upvotes 8 months ago

A new hair loss protocol using FDA-approved topical treatments targets eight pathways, potentially improving results by 60-75% compared to the standard 40-50% from oral minoxidil and finasteride. The protocol includes minoxidil, finasteride, tacrolimus, cetirizine, bimatoprost, lithium gluconate, losartan, melatonin, NAC, caffeine, and tretinoin, with a monthly cost of $35-50 in Mexico and $80-150 in the US.
