    GlossaryTranscription Co-activator

    protein that helps activate gene expression by binding to transcription factors

    A transcription co-activator is a protein that helps turn on the expression of specific genes by binding to transcription factors, which are proteins that directly interact with DNA. While co-activators do not bind to DNA themselves, they facilitate the assembly of the transcription machinery, enhancing the efficiency of gene transcription. This process is crucial for regulating various biological functions, including hair growth and the response to conditions like alopecia.

      Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

      Diffuse hair loss and scalp biopsies

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 3 months ago
      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
