This study suggests that the CXCL8 gene may regulate cashmere fineness in Liaoning cashmere goats, providing new insights into the cellular mechanisms of cashmere growth and quality.

This study examined genetic adaptations in Tibetan sheep through whole-genome resequencing, identifying key genes related to hypoxia tolerance, wool color, and body size. These findings provide a foundation for future molecular breeding strategies to enhance wool quality and adaptive traits in these high-altitude environments.

This study explored the molecular communication between hair matrix cells and dermal papilla cells in cashmere goats, revealing key ligand-receptor pairs and signaling pathways that facilitate intercellular crosstalk and potentially influence hair growth mechanisms.

This study analyzed RNA-seq data from various animal breeds and suggested that similar molecular mechanisms may underlie wool fineness in different sheep breeds. Researchers identified 32 candidate genes related to hair follicle regulation, providing insights for molecular breeding and evolutionary studies.

In this study, ceruloplasmin and keratin 4 were identified as markers that differentiate between growing and resting phases in cashmere goat hair follicles, with keratin 4 being a potential marker for the onset of a new hair cycle.

This study used transcriptome analysis to explore the genetic mechanisms behind the development and seasonal variation of nuptial pads in R. chensinensis, identifying key genes and processes that suggest the pads' development involves complex regulatory pathways, particularly those related to cell cycle and hormone synthesis.

In a controlled study, researchers observed that lambs exposed to colder temperatures had increased wool growth, thicker skin, altered physiological traits, and activated specific molecular pathways, highlighting potential targets for enhancing cold tolerance, welfare, and productivity in sheep breeds.

This study found that specific junctional proteins are significantly downregulated in balding regions of the scalp in men with androgenetic alopecia, suggesting disrupted cell communication may play a role in hair loss.
