In this study, researchers found that SIRT7 activates quiescent hair follicle stem cells to promote hair growth in mice by triggering the telogen-to-anagen cycle transition, with potential implications for age-related hair loss.

This study found that the Gsdma3 gene is necessary for normal hair follicle differentiation in mice, with its mutation leading to progressive hair loss and defects in hair structure.

This study found that treating patients with androgenetic alopecia using exosomes from adipose tissue stem cells over 24 weeks significantly increased hair density and patient satisfaction without severe adverse effects, suggesting a promising alternative treatment for hair loss.

This study found that overexpression of ovine β-catenin in transgenic mice increased hair follicle density by promoting the transition from catagen to anagen.

This study found that components in the kernel of Prunus mira Koehne, such as vitamin E and β-sitosterol, may promote hair growth in mice, possibly involving the Wnt/β-catenin signaling pathway.

This study found that Plerixafor, a CXCR4 antagonist, promotes melanogenesis in melanocytes by increasing MITF and tyrosinase expression and enhancing melanocyte migration, and it effectively restores pigmentation in a mouse depigmentation model without toxicity, highlighting its potential for treating pigmentary disorders.

This source states that an image was mistakenly misused in the supplementary materials but clarifies that this does not impact the study's main findings. The authors have corrected the error for accuracy and transparency.

This study investigates the role of retinoic acid in regulating hair follicle stem cell homeostasis to identify new potential targets for treating androgenetic alopecia.

In this study, components like vitamin E, β-sitosterol, and linoleic acid in the kernel of Prunus mira Koehne were reported to promote hair growth in mice, possibly through the Wnt/β-catenin pathway.

This study suggests that folliculin, mutated in Birt–Hogg–Dubé syndrome, and its partner FNIP1 may play a role in energy and nutrient sensing through the AMPK and mTOR pathways.

In this study, researchers identified four novel variants in the FGF5 gene associated with the long-haired phenotype in dogs, suggesting additional unexplored genetic factors contribute to this trait beyond the known Lh1-Lh5 alleles.

This study found distinct differences in UEA I glycoprotein binding on follicular keratinocytes between anagen and telogen hair follicles, with staining associated with follicle length and regrowth.

This study found that melatonin upregulates LncRNA16913.1, which sequesters chi-miR-195-5p to release FZD6 and enhance fibroblast proliferation in cashmere goat skin, suggesting a regulatory mechanism within the lncRNA-miRNA-mRNA cascade in vitro.

This study suggests that LONRF1 may play a vital role in linking oxidative damage responses and tissue remodeling during wound healing, with distinct mechanisms in senescent and non-senescent cells.

This study generated a transcriptomic map of human hair follicles, identifying compartment-specific gene expression profiles that can aid in developing targeted therapies for hair follicle disorders.

This study found that home use of low-level light therapy reduced inflammation and symptoms like itching and burning in women with frontal fibrosing alopecia over six months.

This study identified the transcription factor Elf5 as a novel regulator of keratinocyte proliferation and differentiation in skin, with expression elevated in stem/progenitor cell populations, suggesting its potential role in determining cell fate during skin and hair development.

In this study, researchers characterized the FGF5 gene in Chinese Merino sheep, identified a new mRNA splicing variant, FGF5S, and noted its restricted expression in the brain, spleen, and skin.

This study reported that the absence of Lsh in skin led to significant epidermal hyperplasia and altered gene expression, suggesting its crucial role in regulating epidermal proliferation, differentiation, and wound healing.

This article describes the development milestones and recent approvals of ritlecitinib for treating severe alopecia areata, with approvals in the USA and Japan and ongoing regulatory reviews in other regions.

TCHHL1 is a protein important for hair growth, found in hair follicles.

This study identified a new FAK isoform, FAKΔe4, which is regulated by ECM stiffness and affects cell migration, invasion, and mechanosensing in human-derived data and engineered models.

This study found that limb hair loss in frontal fibrosing alopecia is inflammatory and permanent, but lacks the classic scarring features seen in scalp alopecia, prompting potential misdiagnosis as alopecia areata.

This review synthesizes the diverse roles of the transcription factor LHX2 in development, tissue maintenance, and injury repair across various organ systems, highlighting its potential therapeutic applications and significance in regenerative medicine, particularly in developmental disorders and tissue regeneration.

Frontal fibrosing alopecia is a scarring hair loss condition mainly affecting postmenopausal women, with unclear causes.

This study found that frontal fibrosing alopecia and lichen planopilaris have similar histopathological features, but FFA exhibits more prominent apoptosis and less inflammation with spared interfollicular epidermis.

In this study, baricitinib treatment improved the differentiation of skin-derived precursors into adipocytes for diseases like Hutchinson-Gilford progeria syndrome, suggesting potential benefits when combined with lonafarnib.

This study identified potential new adverse drug reaction signals for erlotinib, used in lung and pancreatic cancer treatment, by analyzing a large dataset of case reports, indicating further clinical studies are necessary to confirm these findings.
