MiR-125b regulates the differentiation of hair follicles in Fine-wool Sheep and Cashmere goats by targeting MXD4 and FGFR2.

With the development of miRNAs identification technology, more and more miRNAs have been discovered, and the role of miRNAs in the development of animal hair follicles has become a focus of research on hair-producing animals. In the previous experiment, compare the microRNA (miRNA) trancriptomes of goats and sheep skin using Solexa sequencing and differentially expressed miR-125b was screened. However, the mechanism of miR-125b regulating hair follicle development is not clear.

Transcriptome-Wide Comparative Analysis of microRNA Profiles in the Telogen Skins of Liaoning Cashmere Goats (Capra hircus) and Fine-Wool Sheep (Ovis aries) by Solexa Deep Sequencing.

Compare the microRNA (miRNA) trancriptomes of goat and sheep skin using Solexa sequencing to understand the development of skin and hair follicles (HFs). miRNA expression patterns vary in the two small RNA libraries from goat (G library) and sheep (S library) telogen skin samples. Analysis of the size distribution of 25.

Differential expression of the melanocortin-4 receptor in male and female C57BL/6J mice.

The melanocortin 4 receptor is a member of melanocortin receptors of G-protein-coupled receptors. By binding to melanocortin receptor agonists or antagonists, MC4R participates in the regulating of food intake, weight, energy homeostasis and sexual behavior. By activating the protein kinase A and leptin-melanocortin signalling pathways, MC4R mediates the amplification of signals from the hypothalamo-pituitary-adrenal and hypothalamo-pituitary-thyroid axes.

The melanocortin 1 receptor (MC1R) inhibits the inflammatory response in Raw 264.7 cells and atopic dermatitis (AD) mouse model.

The alpha melanocyte stimulating hormone receptor (MC1R) is one of five G-protein coupled receptors belonging to the melanocortin subfamily, MC1R gene has been known to play a major role in regulating of fur color in mammals, and α-MSH and ACTH are endogenous nonselective agonists for MC1R. However, we found that MC1R was highly expressed in Raw 264.7 cells which were important inflammatory cells involved in the initiation of inflammatory responses.
