hair growth genetic diversity selective signatures SNPs selective sweep genes reproduction immunity lactation thermoregulation

TLDR Xiangdong black goats have moderate genetic diversity, minimal inbreeding, and important genes for reproduction, immunity, and other traits.

This study conducted whole-genome resequencing on 20 Xiangdong black goats and 139 samples from six other Chinese goat breeds to explore their genetic diversity and selective signatures. The analysis identified 19,133,125 SNPs, mostly in intergenic and intronic regions, and revealed that Xiangdong black goats have moderate genetic diversity, minimal inbreeding, and a substantial effective population size. Population structure analysis showed reduced genetic differentiation compared to some breeds but greater divergence from Jining goats. Selective sweep methods identified genes related to reproduction, immunity, lactation, hair growth, and thermoregulation. These findings provide valuable insights for breeding and conservation programs.

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.

community Are the japanese Finasteride 10 year studies even relevant to caucasian men - especially young ones?

in Technology 105 upvotes 1 year ago

The conversation is about the effectiveness of hair loss treatments, specifically finasteride and dutasteride, in different populations. Some users believe that the results of Japanese studies may not be relevant to Caucasian men, especially young ones, and that East Asians may respond better to these treatments. Others argue that clinical studies should be the basis for decision-making, while acknowledging that individual responses to medications can vary.
