Polymorphisms of FST gene and their association with wool quality traits in Chinese Merino sheep. [PDF]

PLoS ONE, 2017
Follistatin (FST) is involved in hair follicle morphogenesis. However, its effects on hair traits are not clear. This study was designed to investigate the effects of FST gene single nucleotide polymorphisms (SNP) on wool quality traits in Chinese Merino

Accumulation and Determination of Phenylethanolamine A Residue in Hair of Swine and Sheep [PDF]

Journal of Analytical Toxicology, 2016
The present study proposed the use of liquid chromatography-tandem mass spectrometry to detect the novel β-agonist phenylethanolamine A (PEA) in incurred hair samples of swine and sheep and to assess its accumulation for residue monitoring. The method showed good percent recoveries ranging from 93.2% to 102% and good coefficient of variation at

Gene expression in sheep skin and wool (hair)

Genomics, 2004
We sequenced 2939 ESTs from fetal and adult sheep skin. Stages of gestation were picked to coincide with the major events in skin appendage (wool follicle) formation. Clustering analysis generated a nonredundant set of ESTs 2435 strong (83% nonredundant).

Differential Methylation and Transcriptome Integration Analysis Identified Differential Methylation Annotation Genes and Functional Research Related to Hair Follicle Development in Sheep

Frontiers in Genetics, 2021
Hair follicle growth and development are a complex and long-term physiological process, which is regulated by a variety of physical factors and signal pathways.

Characterization of the Promoter Regions of Two Sheep Keratin-Associated Protein Genes for Hair Cortex-Specific Expression. [PDF]

PLoS ONE, 2016
The keratin-associated proteins (KAPs) are the structural proteins of hair fibers and are thought to play an important role in determining the physical properties of hair fibers.

Purification and Calcium Dependence of Transglutaminases from Sheep Hair Follicles [PDF]

Bioscience, Biotechnology, and Biochemistry, 1997
To study the calcium sensitivity of sheep hair follicle transglutaminase, which was reportedly calcium-independent [H. W. Harding and G.E. Rogers, Biochemistry, 11, 2858-2863 (1972)], the enzyme was purified from a homogenate of merino sheep hair follicles and its calcium dependence was examined.

Contributions of the hair sheep breed Santa Ines as a maintenance host for Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) in Brazil

Parasites & Vectors, 2014
Background Hair sheep breeds are a new, cost-effective option for the diversification of livestock in the Midwest region of Brazil. They are grazed extensively with cattle as well as in isolation in small areas.

LncRNAs regulate the cyclic growth and development of hair follicles in Dorper sheep

Frontiers in Veterinary Science, 2023
IntroductionHair follicles in Dorper sheep are characterized by seasonal cyclic growth and development, consequently resulting in hair shedding during spring.

Heat stress effects on sheep: Are hair sheep more heat resistant?

Theriogenology, 2020
Climatic variables can trigger physiological, biochemical, haematological and hormonal alterations that influence the maintenance of homeothermy and can affect production and productivity in sheep. Different mechanisms are responsible for tolerance to heat stress (HS) including coat and skin colour, body size, fat distribution, physiological reactions ...

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

Advanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.
