This article argues that prolactin may have a role in sebaceous gland function and suggests it could be a potential target for treating skin conditions, but reports no new clinical findings.

This study suggests that progesterone has both THP/GABAA-dependent and independent anticonvulsive effects in a hippocampal-kindled mouse model.

This study found that Ishige sinicola extract increased hair growth and cell proliferation in cultured vibrissa follicles and mice, suggesting potential benefits for treating alopecia through β-catenin activation and 5α-reductase inhibition.

This study reported advances in identifying low-abundance proteins in wool by using fractionation techniques to reduce the dominance of intermediate filament proteins, improving the understanding of the wool proteome.

This study suggests that Foxn1 acts as a brake on PKC signaling in keratinocytes, thereby modulating the stages of differentiation by controlling PKC activity.

This study found that taurine uptake by isolated human hair follicles promoted hair survival and protected against TGF-β1-induced damage in an in vitro setting.

In this study, severe hair loss occurred in PKC epsilon transgenic mice treated with DFMO during skin tumor prevention, highlighting a link between polyamine biosynthesis, hair follicle maintenance, and metastasis suppression.

In this study, the methanol extract of Cercidiphyllum japonicum heartwood was found to stimulate the proliferation of mouse hair epithelial cells, with several isolated compounds showing significant proliferative activities.

This study reported that a 1% procyanidin B-2 tonic increased hair diameter and density in men with male pattern baldness, suggesting it may be a potential treatment option.

This study found that manipulating prolactin levels in New Zealand Wiltshire sheep induces wool follicle growth cycles, revealing gene expression changes that suggest roles for specific genes in follicle function.

Finasteride affects prostate weights and pituitary activity differently with age.

In this study, researchers found that deleting Caspase-9 in hair follicle stem cells delayed apoptosis, leading to accelerated wound repair and new hair follicle regeneration by maintaining apoptotic cells as signaling centers.

This study found that hair products commonly used by Black women exhibited hormonal activity, which could impact health outcomes and contribute to health disparities.

This review summarizes preclinical and clinical information on herbal products for hair loss treatment, highlighting their mechanisms, follicular penetration, and potential side effects, suggesting they may offer alternatives to synthetic drugs with fewer side effects.

This study observed that overexpressing TSPO in the hippocampal dentate gyrus of mice led to significant anxiolytic and antidepressant-like effects, potentially mediated by increased allopregnanolone synthesis.

In this study, short-term finasteride treatment reduced apoptotic factors caspase-7 and IGFBP-3 in prostate cancer cells but did not significantly affect androgen receptor expression compared to placebo.

This study characterized the mouse profilaggrin gene, finding it structurally identical to its human counterpart, and noted differences in protein-coding regions that could impact epidermal differentiation.

Propranolol affects heart rate and renin levels in minoxidil-treated patients.

This study found that the progesterone metabolite 3α-THP increased the proliferation and gene expression of human glioblastoma cells, suggesting a role in tumor progression.

This study suggests that common proteomic changes, including the expression of the protein S100A6, may occur during the expansion of AD-MSC from different donors.

This study found that adding certain conditioning agents, including jojoba oil and lauryl PEG/PPG‐18/18 methicone, to ammonium thioglycolate straightening emulsions protected Afro-ethnic hair from protein loss and improved resistance to breakage.

This study found that chronic exposure to and withdrawal of progesterone influenced the expression and function of GABA A receptors in rat hippocampal neurons through its metabolite 3α,5α‐THPROG.

Adding zinc to pyrithione zinc improves its effectiveness against scalp conditions like dandruff.

This study in female beagle dogs found that long-term exposure to oral contraceptive steroids resulted in significant reproductive and mammary gland changes, with the relevance to human tumor risk remaining uncertain.

This study concluded that exposing anestrous brood mares to a 16-hour photoperiod in early December led to endocrinologically normal estrous cycles starting within two months, enabling earlier breeding and foaling.

This study characterized proteins in hair-follicle and hair tissue, identifying similar protein types but with notable quantitative differences, which may reveal aspects of keratin protein synthesis.

This study found that biostimulant application in lettuce cultivation led to significant yield and phytochemical enhancements, with effects varying between green and red cultivars depending on the treatment method used.

This study found that Runx1 in hair follicle stem cells modulates lipid metabolism, impacting membrane organization and enhancing signal transduction for cell proliferation in both normal and cancer epithelial cells.

This article reviews the roles and mechanisms of stem and progenitor cell migration in adult organs for tissue homeostasis and regenerative medicine, but reports no new experimental results.

This article describes a potential novel approach to reduce chemotherapy-induced hair loss by enhancing the expression of specific transporters in hair follicles, but reports no clinical results.
