In this study, researchers found that the G(S)alpha subunit is strongly expressed in neonatal mouse hair follicles, indicating it may play a role in initiating follicle growth.

This study identified core genes and pathways involved in androgenetic alopecia, finding that genes related to hair follicle development are down-regulated, while those linked to immune responses are up-regulated, highlighting potential therapeutic targets.

In this study, researchers observed that the KAP8-1 gene influences skin and hair follicle development and wool quality with varying expression levels in different Ovis aries crossbred varieties.

This study found that IGFBP-5 may play a significant regulatory role in the hair follicle development of Inner Mongolia Cashmere goats, with more consistent expression patterns across different stages.

In this study, oral collagen peptides increased certain gene expressions related to epidermis development and the hair cycle in hairless mice skin, suggesting potential links to hair health.

This study found that in male yaks, 5α-red1 may play a crucial role in synthesizing DHT to promote hair follicle growth, while E2 synthesized by epithelial cells may inhibit this growth through ERα.

In this study, elevated mRNA levels for serine-rich ultra high sulfur proteins were observed during active hair growth phases in mice, particularly in the forming hair structures and upper skin layers.

In this study, topical application of Cyclosporin A on mice skin induced hair growth by transitioning follicles from telogen to anagen, but no effect was observed on cultured human hair follicles.

This research discusses the time-of-day-dependent role of protein-complex assembly in the differentiation of human epidermal stem cells and highlights the context-dependent functioning of human protein complexes.

This study found that cortisol increases mac25/IGFBP-rP1 expression in osteoblast-enriched cells from fetal rat calvariae, indicating transcriptional regulation which may influence IGF and insulin effects in bone.

In this study, oral contraceptive use in women with PCOS increased the expression of certain inflammatory gene markers, which were positively associated with metabolic abnormalities.

In vivo using the C3H mouse model, this study observed that BST2 expression occurs before hair loss in alopecia areata and is followed by an increase in epidermal γδ T cell numbers.

This study found that oral collagen peptides increased expression of genes associated with epidermis development and the hair cycle in hairless mice, providing insights into their potential skin benefits.

This study observed that Tudor-SN protein may play a significant role in the immune system and that polyamines can influence hair growth in a mouse model.

This study found that patients with androgenic alopecia had altered neuroactive steroid levels and depression symptoms after stopping finasteride treatment, suggesting lingering neuropsychiatric effects.

In this study, transgenic mice with a truncated latent transforming growth factor-beta-binding protein showed reduced keratinocyte proliferation and alterations in the hair cycle due to mis-localization of transforming growth factor-beta.

This study found significant changes in gene and protein expression related to hair follicle development in Rex rabbits' skin during the first 8 weeks of life.

This study found that transthyretin and megalin expression in human scalp hair follicles varies significantly with the hair growth cycle, peaking during anagen and diminishing in catagen and telogen phases.

This study found that expression of GDNF and GFR α-1 proteins in human skin decreases with age, particularly in the epidermis, suggesting that their signaling pathways may be altered as people grow older.

This study found that miRNA-24 downregulates the KLF6 gene, influencing coat color by affecting melanogenesis pathways in Cashmere goats, and that miRNA-24 inhibition increased melanin content in mice.

This study found that Wnt7a protein expression increased after corneal epithelial injury and promoted human corneal epithelium cell proliferation by upregulating fibronectin and enhancing cell adhesion.

The researchers reported that applying proteolytic enzymes to mice skin negatively affected hair follicles, leading to degeneration and potential impairment of stem cells from the bulge area.

This study found that oral collagen peptides increased the expression of genes related to epidermal and hair cycle development in hairless mouse skin.

This study found that transgenic mice overexpressing the BMP antagonist noggin showed increased hair follicle size and altered hair type, linked to changes in cell proliferation and gene expression.

This study observed that combined treatment with thyroxine and hydrocortisone increased lipid accretion and fat cell development in hypophysectomized fetal pigs, suggesting a key role of these hormones in fetal adipogenesis.

Alopecia areata may involve stress-related changes affecting hormone receptors, leading to reduced cortisol production.
