In this study, researchers found that size polymorphisms in certain hKAP1 genes are linked to the hKAP1.1B and hKAP1.3 genes, arising from intragenic deletions and duplications in Japanese and Caucasian populations.

This study suggests that mTORC1 may play a role in regulating the timing of hair growth cycle phases, particularly the initiation of the anagen phase.

This case report observed that a 23-year-old man developed painful unilateral gynecomastia after two months of low-dose finasteride treatment for male androgenetic alopecia, which resolved after discontinuation.

This genetic study identified a potential interval for the Marie Unna hypotrichosis gene but found no mutations in the nearby hr gene, suggesting its involvement remains unconfirmed.

Allergic contact dermatitis may promote hair growth by activating hair follicle stem cells.

This study highlights a paradox where valproic acid, known for causing hair loss, may also promote hair growth when applied topically.

This study found that STAT5 activation in the dermal papilla acts as a key switch to trigger anagen entry in postdevelopmental hair follicle cycling.

Mycophenolic acid may help hair grow by activating pathways important for hair growth.

This study found that the interaction between heat shock protein 90 and lamin A/C is crucial for the growth, migration, and self-aggregation of dermal papilla cells, suggesting a potential role in alopecia areata mechanisms.

This study suggests that while PTH rP initially seemed to shorten the hair cycle by transitioning hair follicles from anagen to catagen, more relevant models indicate it ultimately accelerates and stimulates hair growth.

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 in mice with alopecia areata, CD8+ T cells showed clonal expansion and specific regulatory networks, which might help identify new therapeutic targets for patients not responding to JAK inhibitors.

This case report describes a 3-year-old boy with atrichia with papular lesions, emphasizing that dermoscopy, showing the 'cluster of stars' appearance, facilitated diagnosis without needing a skin biopsy.

This study found that overexpression of miR-122 in balding hair follicles may induce apoptosis in human dermal papilla cells by repressing IGF1R, suggesting a new potential pathological mechanism in androgenetic alopecia.

This study found that a specific fragment of AIMP1 secreted by hair follicle stem cells can stimulate dermal papilla cells and promote hair regrowth.

This study found that urokinase plasminogen activator (uPA) is elevated in hyperproliferative hair follicle keratinocytes in mice, and its inhibition significantly reduces their proliferation.

In this study, topical trypsin treatment following depilation in a mouse model induced cell death at the follicular papilla, delaying hair growth and pigmentation.

This study found that EPHA4 and Ephrin A3 genes are differentially expressed during hair follicle development in fine-wool sheep, suggesting roles in follicle regeneration and density.

This study found that balding dermal papilla cells show premature senescence and altered expression of stress and DNA damage markers, suggesting sensitivity to environmental stress in androgenetic alopecia.

This study found six new genetic factors linked to early-onset androgenetic alopecia and its association with increased risk of Parkinson's disease and decreased fertility.

Chemotherapy patients don't all lose their hair due to factors like hair growth rates, age, genetics, and the type of drugs used.

In this mouse model study, researchers found that deleting the ASH2L gene in epidermal progenitor cells led to thinner epidermal layers, delayed hair follicle development, and reduced epidermal stem cell pools, with alterations in genes related to hair follicle development and the Notch signaling pathway.

This study found that the N-terminal fragment of AIMP1 enhances hair growth and proliferation of hair follicle stem cells in mice, suggesting its potential as a therapeutic peptide for hair loss treatment.

This study identifies a new mutation in the Scd1 gene in a strain of Kunming mice, causing skin and hair defects with the mildest impact among similar mutations.

This study detailed distinct immunophenotypic stages of alopecia areata in C3H/HeJ mice, providing an immune blueprint that may help identify therapeutic targets for disease pathways in humans.

Arg1+ macrophages may play a role in Alopecia Areata, offering new treatment targets.

This study reported that dilated follicular infundibula are a highly useful histopathologic criterion for diagnosing alopecia areata, particularly during its recovery stage.

In this study, testing Annurca apple extract on human follicle dermal papilla cells indicated its potential to prevent patterned hair loss by reducing oxidative stress and increasing factors involved in hair growth.
