GlossaryPlakophilin-1

protein crucial for cell adhesion in skin and hair

Plakophilin-1 (PKP1) is a protein that plays a crucial role in the formation and maintenance of desmosomes, which are structures that help cells stick together, particularly in tissues that experience a lot of stress, like the skin and heart. Mutations in the gene encoding Plakophilin-1 can lead to skin disorders and hair loss conditions, such as ectodermal dysplasia/skin fragility syndrome, highlighting its importance in maintaining the integrity of epithelial tissues.

community MCL1 does anyone knows anthying about it

in Research/Science 9 upvotes 1 year ago

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

community The story of RU58841/PSK3841

in Research/Science 1 year ago

RU58841, an anti-androgenic compound, showed early promise for treating alopecia but faced challenges after its patent in 1997. Despite advancing to Phase II trials, safety concerns and financial struggles led Aventis to abandon its development. Proskelia, which later merged into ProStrakan, couldn't prioritize the drug, leading to its eventual stagnation and failure to reach the market.
