In this study, androgen receptors were found only in the mane follicles of red deer stags during the breeding season, suggesting their expression is induced by seasonal hormone changes.

This study found that in male yaks, 5α-red1 may play a crucial role in synthesizing DHT to promote hair follicle growth, while E2 synthesized by epithelial cells may inhibit this growth through ERα.

This study found that melatonin administration effectively shortened the fur maturation period and altered hair follicle cycling in chinchillas.

This review examines the role of androgens and androgen receptors in regulating glucose and lipid metabolism, focusing on their effects on mitochondrial content and function; it also discusses the sex-dimorphic influence of androgens and provides theoretical insights into their mechanisms.

This study found that nicotine caused damage to cochlear hair cells in vitro, and melatonin might protect against this damage, indicating its potential as a treatment for smoking-induced hearing loss.

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 overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This study found that dihydrotestosterone induced hair loss and changes in hair morphology in male C57BL/6 mice, effects that could be partially reversed by the AR antagonist bicalutamide.

This study found that carvone, a plant-derived compound, decreases melanin content and inhibits melanoma cell proliferation through the cAMP pathway, suggesting potential benefits for treating melanomas and other hyperpigmentation disorders.

This study found that Cnidium officinale extract and its compound ferulic acid improved hair growth by promoting dermal papilla cell function and mitochondrial activity, suggesting their potential as a new treatment option for alopecia, possibly through estrogen receptor alpha activation.

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 found that premature hair loss due to stress does not occur in NK-1 receptor knockout or mast cell deficient mice, suggesting a key role for neurokinin substance P and mast cell interaction in stress-related hair follicle changes.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

This study suggests that icariin promotes hair follicle growth in mice by enhancing IGF-1 expression in dermal papilla cells.

This review discusses the early phases of melanomagenesis and the factors influencing melanoma cell variability and reports no new clinical results.

This study in Italy found that APS-1, a rare disorder, is associated with various AIRE gene mutations and most individuals have autoantibodies such as IFNωAbs, which are markers of the condition.

This study found that patients with myotonic dystrophy types 1 and 2 often exhibit skin abnormalities, which correlate with genotype severity and serum vitamin D levels, and suggest premature aging.

This review provides an in-depth analysis of the structure and function of c-kit activation, and its role in both normal physiological and pathological conditions, with no new research findings reported.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

In this study, OCT showed strong nuclear binding in certain skin cells, suggesting similar genomic effects to vitamin D with potential therapeutic benefits due to its lower calcaemic effect.

This study reports that PDRN, commonly used for wound healing, may also have anti-melanogenesis and potential skin whitening effects in both experimental models and clinical settings.

Skin-derived stem cells could help treat skin aging and pigmentation issues.

This case report is the first in Brazilian literature to document Becker nevus syndrome, featuring Becker's nevus, ipsilateral breast hypoplasia, and scoliosis in a 14-year-old girl.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This review explores genetic and lifestyle factors influencing hair diversity and reports no new findings, calling attention to the potential for future discoveries in genetic and epigenetic research.

In this study, applying deer antler velvet extract-loaded niosomes and microspicules serum to the scalp significantly improved hair growth, melanin content, and skin hydration over 14 to 30 days without causing skin irritation.

This review summarizes the potential of N-acetyl-cysteine in managing diseases linked to redox imbalance, discussing its effects from cellular mechanisms to clinical applications, though further research is suggested for broader use.

Pharmacists play a crucial role in customizing treatments and ensuring medication safety.
