This review highlights the role of the skin's photosensory system in mediating responses to UVA radiation, contributing both to immediate protective effects and to broader circadian and seasonal adaptations, but reports no new experimental results.

This study suggests that biotin-rich functional food may stimulate hair growth and prevent hair loss through improved cholesterol and lipid metabolism and blood flow in men.

Ets2 gene is crucial for placental development in mice.

This review discusses melatonin's potential in dermatology, highlighting its antioxidative, immunomodulatory, and DNA repair properties, but reports no new clinical results.

In this study, researchers linked defects in U2HR, an inhibitory region in the HR gene, to Marie Unna hereditary hypotrichosis, suggesting a mechanism for controlling hair growth and addressing hair loss.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This study reports that overexpression of activin in transgenic mice enhances granulation tissue formation during wound healing, highlighting a novel role for activin in cutaneous repair processes.

This study found that untreated men with coeliac disease exhibited androgen resistance, potentially linked to sexual dysfunction, which improved as intestinal health improved, a pattern not observed in other chronic illnesses.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

This review discusses the origins of skin and esophageal cancers and reports no clinical results; it emphasizes the role of cyclooxygenase-2 in tumorigenesis and differentiation.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

This review discusses advances and challenges in skin tissue engineering, focusing on developing 3D constructs for functional skin substitutes, and reports no new clinical results.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This study found that local androgen biosynthesis and metabolism in human sebaceous glands play a crucial role in sebum synthesis and secretion.

This study reports an increased frequency of the DI genotype of the ACE gene polymorphism among women with PCOS, notably in those with hyperandrogenism, and an association of the II genotype with insulin resistance.

This study identified specific miRNAs and mRNAs involved in the development of secondary hair follicles in cashmere goats, particularly noting a targeted relationship between chi-miR-30e-5p and DLL4.

This review discusses the functional and nutraceutical importance of wheat straw, emphasizing its bioactive compounds and potential benefits, and reports no new experimental findings.

This study compared the echocardiographic profiles of patients with polycystic ovary syndrome to those of healthy subjects using conventional methods and tissue Doppler imaging, but it reports no specific findings here.

This study identified a novel homozygous EDNRA variant linked to Oro-Oto-Cardiac Syndrome and showed that EDNRA signaling is essential for normal craniofacial and cardiovascular development.

The researchers observed that normal murine hair follicles are direct targets for melatonin, with receptor expression varying throughout the hair cycle, suggesting melatonin's role in hair cycle control.

In this study, researchers found that the novel gene circCFAP20DC enhances the proliferation of goat follicular granulosa cells by activating the RB pathway, facilitating their progression from the G1 to S phase during follicular development.

This article describes a protocol for using bioengineered techniques to regenerate functional hair follicles and their stem cell niches by manipulating epithelial and mesenchymal cells.

This review discusses the role of skin enzymes in drug metabolism and emphasizes the need for models assessing enzyme activity to evaluate the safety and bioequivalence of topical generic drugs, highlighting efforts to standardize testing protocols for transdermal products.

This study developed a new method for detecting 30 hormones in anti-aging functional foods, demonstrating good sensitivity and reliability, and identified seven hormones in four out of 14 samples tested.

This article reviews the role of KLF4, a transcription factor, in various cellular processes and its dual function as a tumor suppressor or oncogene depending on the context, but presents no new experimental results.

In this pilot study, finasteride increased testosterone/dihydrotestosterone and progesterone/dihydroprogesterone ratios in normal ovulatory women but did not alter ovulation or gonadotropin secretion.

This study suggests that increased activity of the histamine synthesizing enzyme histidine decarboxylase may play a role in initiating the anagen phase of hair regrowth in mice.

The GH-IGF-I axis is likely involved in the hormonal imbalances seen in non-obese women with functional hyperandrogenism.
