TLDR Wild African goats have genetic adaptations for surviving harsh desert conditions.

The study on the wild African goat (Capra nubiana) identified several genetic adaptations to harsh desert environments through genome-wide scans. Key findings include positive selection in genes related to skin barrier and hair follicle development, DNA repair, and immune response, such as ABCA12 and UVSSA. The research also detected numerous copy number variations (CNVs) affecting genes involved in immune response and xenobiotic metabolism. These genetic adaptations likely support the species' survival in extreme conditions, providing valuable insights for conservation and breeding programs to enhance resilience in domestic goats.

community Keratin microspheres - breakthrough

in Research/Science 13 upvotes 9 months ago

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.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 4 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.
