This study found that supplementing Liaoning cashmere goats with HMBi increased cashmere length while decreasing its diameter, attributed to changes in Met-related metabolites and elevated expression of genes related to the Met cycle and cell differentiation pathways such as Wnt and MAPK.

The researchers reported that mast cell and nerve fiber interactions in mouse skin are highly selective for nerve fiber types and vary depending on the hair cycle phase.

This study found that rats fed a diet with different protein qualities and levels showed significant differences in hair cycle length, daily weight gain, and hair density.

This study found that ethionine significantly inhibited wool growth in sheep, with L- and D-isomers being equally effective, but did not cause hair loss in sucking mice or rats.

This study identified 617 differentially expressed genes in cashmere goat hair follicles, which are involved in key biological processes and provide insights into hair follicle development.

In this study, researchers found that substance P and calcitonin-gene-related peptide have distinct roles in the regulation of hair growth in mice, suggesting potential therapeutic targets for hair growth manipulation.

In this study, mice on a methionine-deficient diet experienced hair loss, which was not remedied by homocysteine supplementation; hair regrowth only resumed after methionine was reintroduced, suggesting dietary methionine is essential for hair maintenance.

In this study, a low-methionine diet significantly improved the health and physical traits of cystathionine β-synthase-deficient mice, contrasting with negative effects on mice with partial deficiency.

This study demonstrated that bioluminescence imaging of NG2+ cells in transgenic rats allows in vivo monitoring of hair follicle cycles to study hair growth and follicle regeneration.

This study demonstrated that mink hair growth and pelt quality significantly depend on dietary protein levels and DL-methionine supplementation during the growing-furring period.

This study suggests that increased activity of the histamine synthesizing enzyme histidine decarboxylase may play a role in initiating the anagen phase of hair regrowth in mice.

In this study, lipid peroxides were found to induce apoptosis in hair follicle cells and advance the catagen phase in mice, suggesting a potential mechanism for alopecia development.

This study found that substance P and calcitonin-gene-related peptide have different roles in regulating hair growth in mice, with substance P promoting anagen progression and calcitonin-gene-related peptide inhibiting it.

This review discusses dietary manipulation strategies in a mouse model of CBS deficiency and reports no new results; the authors emphasize the importance of understanding gene-diet interactions.

This study demonstrated that phosphatidylcholine liposomes can deliver calcein and melanin into hair follicles and shafts in mice without significant penetration into the dermis, epidermis, or bloodstream.

This study found that cutaneous pyridoxal 5'-phosphate hydrolase activity may be carried out by an enzyme different from the classical tissue-nonspecific alkaline phosphatase in human and mouse skin.

This review discusses the role of diet in managing hair loss during menopause and reports no new clinical results; it highlights the importance of nutrients like sulfur amino acids, vitamins, and minerals.

This study found that concurrent administration of cycloleucine with ethionine prevented the weakening of wool fibers in sheep, whereas reduced glutathione did not have the same effect.

This study found that supplementing soybean oil significantly increased the production of the cyclosporine A derivative [(4'-OH)MeLeu]4-CsA by 55.6%, offering potential enhancements for its clinical application.

This study found that the hairless gene product (Hr) suppresses VDR-mediated gene activation by directly interacting with the vitamin D receptor, potentially affecting hair follicle function.

This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This paper reviews recent research on hair graying, suggesting that an imbalance in oxidative stress handling may affect melanocyte stem cells and melanin production with age, and calls for exploring strategies to prolong melanin production.

Hair growth is influenced by factors like genetics and nutrition, and more research is needed to understand hair loss and growth mechanisms.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This study found that ATM protein plays a crucial role in protecting human hair follicle melanocytes from oxidative stress, which is linked to the greying of hair.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This review summarizes 19 patents filed since 2000 for treating or preventing chemotherapy-induced alopecia, but reports no new clinical findings.
