This retrospective pilot study found that oral tofacitinib was more effective in treating alopecia areata than alopecia universalis, but relapses were common after treatment cessation.

This review examines the mechanisms of Janus kinase inhibitors in treating alopecia areata and evaluates their efficacy and safety, but reports no new clinical results.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

This article discusses the autoimmune causes of alopecia areata and reports no new clinical results.

This study found that leukocytes and beard hair follicle cells have an endogenous circadian clock, with PER1 and PER3 expression possibly serving as biomarkers for assessing individual biological clock traits.

This study found that extracting RNA from equine hair follicles can effectively identify 24-hour oscillations of specific circadian clock genes, offering a valuable non-invasive method to evaluate the equine circadian clock.

In this study, bright light exposure during the daytime did not significantly affect clock gene expression in humans, although Rev-erb-ß expression appeared stronger under bright light compared to dim light.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

Chicken feather gene mutation helps understand human hair disorders.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This review discusses the role of circadian rhythms in stem cell differentiation and tissue regeneration, emphasizing their impact on organ physiology and aging, but reports no new experimental results.

This study found that obese Taiwanese women had a lower incidence of acne than non-obese women, despite having higher serum testosterone levels.

The authors concluded that utilizing clock gene expression from hair follicle cells may improve circadian-phase estimation in clinical settings, aiding the detection of circadian-related sleep problems despite social time constraints.

This study investigated the dynamic mechanical properties of fluid-immersed elastic hair beds under oscillatory shear flows, revealing a nonlinear response influenced by driving frequency and amplitude, which impacts mechanosensory signaling stability in biological processes like vasodilation and ciliary remodeling.

This study found that certain nutraceuticals did not interfere with tamoxifen's inhibition of estrogen in breast cancer cells and may enhance its effects, suggesting potential as an adjuvant therapy for hair loss in patients undergoing endocrine therapy.

This study found that the retromer protein AtVPS29 in Arabidopsis plants modulates gibberellin signaling by upregulating the SLY1 protein and downregulating the RGA protein, ultimately enhancing the development of the root meristematic zone.

This study found that the receptor kinase RHS10 negatively regulates root hair growth in Arabidopsis thaliana by modulating growth duration and is associated with cell wall signal mediation, involving RNA catabolism and ROS accumulation.

This review discusses the roles of glucocorticoid and sex hormone receptors in the skin and their clinical importance, but reports no new research findings.

This narrative review highlights the potential of autologous adipose mesenchymal stem cell-derived exosomes (AMSCs-Exos) in anti-skin aging, noting their superior biocompatibility and manufacturing advantages while stressing the need for standardized production protocols to overcome existing application challenges.

This chapter reviews the skin's structure and its clinical relevance, highlighting connective tissue diseases and the potential for novel treatments like protein, cell, or stem cell transfer, but reports no new findings.

This study identified 19 specific genes involved in root hair growth and morphogenesis in Arabidopsis, using a combination of computational and experimental methods.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study found that reducing testosterone levels in male mice accelerates wound healing and decreases inflammation, suggesting a potential therapeutic target for improving wound repair in elderly males.

This review discusses the role of reactive oxygen species in regulating oscillating apoplastic pH gradients and growth in plant root hairs and pollen tubes, reporting no new experimental results.

In this animal study, atorvastatin co-administered with trastuzumab reversed trastuzumab-induced cognitive impairment (chemo-brain) and improved its anti-cancer efficacy without causing hair loss.

This study found that the vitamin D receptor, but not its ligand, regulates genes involved in hair cycle progression, suggesting a role in integrating hormone signaling pathways for hair and epidermal functions.

This review describes therapeutic strategies for polycystic ovary syndrome, highlighting current treatments for ovulation induction and emphasizing lifestyle changes and personalized approaches, but reports no new clinical results.
