Did you mean MAPK signaling?

GlossaryMAPK pathway (MAPK signaling)

crucial cell signaling mechanism regulating growth, division, and stress response

The MAPK pathway, or Mitogen-Activated Protein Kinase pathway, is a crucial signaling mechanism in cells that helps regulate various activities such as growth, division, and response to stress. It involves a series of proteins that communicate signals from the cell surface to the DNA in the nucleus, ultimately influencing gene expression and cellular behavior. This pathway is significant in many biological processes and is often studied in the context of diseases like cancer and conditions affecting hair growth, such as alopecia.

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

in Research/Science 120 upvotes 7 months 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.

community Polydopamine Synergizes with Quercetin Nanosystem to Reshape the Perifollicular Microenvironment for Accelerating Hair Regrowth in Androgenetic Alopecia.

in Research/Science 13 upvotes 7 months ago

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.
