This research outlines how retinoids, compounds based on vitamin A, activate nuclear receptors to influence cellular processes such as differentiation and carcinogenesis, with benefits like anti-inflammatory properties but requiring careful management of dose-dependent side effects.

In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.

This review discusses the mechanisms associated with protoporphyrin IX in living cells and reports no clinical results; the authors emphasize its potential in cancer diagnosis and the risks of toxicity.

This study reported that nanoemulsions significantly improved the skin permeability of thiocolchicoside compared to its aqueous solution, suggesting they are effective carriers for its transdermal delivery.

This study found that ranitidine and finasteride may have cardiovascular and renal protective effects in mice by inhibiting TMAO synthesis and improving gut microbiota composition.

In this study, NREs from lentil root nodules, specifically Serratia plymuthica 33GS and Serratia sp. R6, significantly enhanced lentil growth, altered root exudation, and modulated rhizospheric microbial communities in a greenhouse setting.

In this study, NIH hairless mice showed increased susceptibility to Listeria monocytogenes infection compared to NIH mice, potentially due to differences in gut microbiota and monocyte levels.

This study systematically reviewed meta-analyses and Mendelian randomization studies to identify factors influencing prostate cancer risk, finding suggestive associations for physical activity, height, and smoking but no robust, convincing overlapping evidence across tested factors.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

This study observed that the topical skin-whitening agent rhododendrol induced skin depigmentation in approximately 16,000 consumers, linked to melanocyte cytotoxicity and immune reactions.

This article reviews the impact of H2O2-redox homeostasis on hair follicle pigmentation via tyrosinase and associated mechanisms, discussing primarily findings from murine models without providing new clinical results for humans.

This study suggests that low-dose blue light (453nm) may positively affect hair growth by interacting with the receptors CRY1 and OPN3 in hair follicle cells.

This study found that Rhodamin B staining of keratin was inconsistent across normal skin, epithelial tumors, and dermatoses, with notable differences in staining intensity between tricho-hyalin and keratohyalin granules.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

In this study, researchers reported that the Pinkie mutation in mice, affecting RXRa activity, leads to skewed Th1 development and suggests RXRa's role in Th2 differentiation, impacting immune responses.

This study analyzed clinical and histological reports and concluded that blue light therapy is safe for human skin, with potential photoprotective effects against UV irradiation due to its impact on skin pigmentation mediated by Opsin-3.

This study found that RXR-alpha is strongly expressed in both normal and psoriatic human skin, suggesting it may play a role in the transition from proliferation to differentiation in epidermal keratinocytes.

This review discusses the factors influencing human hair color, including genetic components like the MC1R gene and enzyme activity, without presenting new experimental results.

This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.

This review discusses the factors influencing human hair color, including genetic components and enzymatic activity, and highlights the forensic significance of hair color analysis, but reports no new findings.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This study observed that retinoic acid biosynthesis and signaling in hair follicles have a spatial and temporal regulation linked to distinct stages of the hair cycle in mice.

In this study, researchers identified the CBL1-CIPK26 Ca 2+ sensor-kinase complexes as key modulators of the NADPH oxidase RBOHC crucial for root hair differentiation in plants.

This study found that the protein hairless acts as both a corepressor and coactivator of the vitamin D receptor, influencing gene transcription in a ligand-selective manner.

TRH in hair follicles can influence hair color by increasing melanin.

This study found that external light can rapidly activate hair follicle stem cells in animals via a retinal light-sensing pathway linked to the central and autonomic nervous systems.

This study found that melatonin may enhance hair follicle stem cell viability by downregulating the nuclear receptor RORA, which otherwise inhibits cell proliferation and promotes apoptosis.
