In this study, disruptions in phospholipase A2 activity in Arabidopsis thaliana significantly impaired the plasma membrane localization of PIN proteins, affecting auxin transport and root development.

Ethosomes improve finasteride delivery through skin for hair loss treatment.

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 presents evidence that correlations exist between hair mineral imbalances and various diseases, though inconsistencies in results highlight the need for standardized preparation methods.

This study found that stimulating the olfactory receptor OR2AT4 in human hair follicles with a synthetic sandalwood odorant promotes hair growth ex vivo by decreasing apoptosis and increasing IGF-1 production.

This study found that antibiotic-induced gut dysbiosis, particularly overgrowth of Lactobacillus murinus, can lead to hair loss in mice by depleting biotin.

This article outlines the clinical features, evaluation, and treatment strategies for androgen excess in polycystic ovary syndrome, highlighting important diagnostic and management approaches but reporting no new research results.

This study found that drug delivery through human scalp skin may be more effective for lipophilic and hydrophilic drugs compared to abdominal skin, highlighting the potential of intrafollicular delivery methods.

This review outlines a diagnostic framework for clinicians to distinguish different types of inherited ichthyoses and suggests further testing and treatment strategies, but reports no new clinical results.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

This study suggests that minoxidil activates PGHS-1, which may explain its hair growth-stimulating effects and could aid in designing more potent hair growth-promoting drugs.

This study found that procyanidin oligomers, particularly dimers and trimers, significantly promoted hair growth in mice and hair epithelial cell cultures, suggesting potential use as hair growth agents.

The researchers observed that overexpression of Wnt10b in a mouse model can induce hair follicle regeneration by switching follicles from the resting phase to the growth phase via the Wnt-β-catenin signaling pathway.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

This study observed specific expression patterns of three zebrafish estrogen receptor genes during development, highlighting robust co-expression of esr2a and esr2b in primary neuromasts, branchial arches, and other tissues.

The researchers reported that reactive oxygen species regulate the stress-induced SP-Mast cell pathway, which might support using antioxidants to treat stress-related hair loss.

This study observed that Japanese women experience diffuse central hair loss after age 40, characterized by reduced hair density and thicker hair ratio rather than vellus-like hairs.

This report describes a case of acute liver injury in a woman following the use of Shen-Min, a herbal hair growth supplement, highlighting a potential link to acute hepatitis.

This study discovered nine human type I hair keratin genes, including a transcribed pseudogene, in a 190 kbp genomic region, revealing three gene subclusters based on sequence homologies.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

This study identified that a deficiency in the palmitoyl transferase enzyme, due to a mutation in the Zdhhc13 gene, led to severe physiological abnormalities in mice, including skin, bone, and systemic amyloid issues.

This study found that thyrotropin-releasing hormone (TRH) acts as a potent stimulator of hair growth in human scalp hair follicles, promoting elongation and prolonging the anagen phase.

This study suggests that S100A4 and S100A6 proteins may play key roles in activating stem cells for hair follicle regeneration in mice.

This study found that mTOR signaling plays a crucial role in activating hair follicle stem cells by balancing BMP-mediated repression, essential for hair regeneration.

This study found that short-chain fatty acids produced by the skin microbe Propionibacterium acnes may drive inflammatory gene expression in sebocytes, potentially contributing to acne.

This study explored the interaction between androgen and Wnt signaling in dermal papilla cells, targeting the effects of androgen on hair growth reduction.

This study found that CD45RO+ cells, a subtype of T lymphocytes, were notably reduced in the ovarian follicles of women with PCOS, which may contribute to the condition's pathogenesis.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

In this study, researchers found that exposure to PM10 significantly increased inflammation and impaired collagen synthesis in human dermal fibroblasts, suggesting PM10 contributes to skin aging through these mechanisms.

This study found that in vivo, a novel microneedle system for valproic acid delivery may improve hair regrowth efficacy by upregulating hair follicle development pathways more effectively than topical application.
