Targeting Smoothened for Therapeutic Gain

SCUBE3, a protein linked to hair growth in moles, was discovered over 25 years ago and is being developed by Amplifica for potential hair loss treatment. Concerns exist about SCUBE3's association with cancer, as it is a protein that promotes cell growth, which could potentially trigger cancer development if used for hair growth therapy.

The conversation discusses using PGE2 as a hair growth stimulant, comparing it to minoxidil, and considering the addition of Setipiprant. Concerns about side effects like skin damage and cost are also mentioned.

Osteopontin, a protein involved in hair growth on moles, may help with hair loss. However, it is also linked to Alzheimer's, cancer, and bone development, so caution is advised.

Suvomipic, previously known as PP405, is progressing to Phase 3 trials for hair loss treatment. Its effectiveness compared to existing treatments like Minoxidil and Finasteride is still uncertain.

Hair regrowth on wounded and bald skin may be possible by activating the sonic hedgehog gene, leading to hair regrowth in mice. The findings are promising but may not directly apply to humans.

A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.
