This study found that inhibiting DPP4 during a critical period post-wounding increases hair follicle regeneration and Wnt signaling in large skin wounds.

This study found that vitamin D receptor expression is associated with proliferating keratinocytes, while retinoid X receptor α is linked to differentiating keratinocytes, suggesting differential targeting by vitamin D metabolites.

This study found that the medication dyclonine has a potent inhibitory effect on the TRPV3 channel, effectively rescuing cell death and alleviating pruritus symptoms in a mouse model with gain-of-function TRPV3 mutations, suggesting potential for treating skin inflammation.

This study found that TPA treatment transiently induces high levels of ODC in mouse epidermal cells, particularly around hair follicles, with localization reduced by retinoic acid or cycloheximide pretreatment.

This study found that the peptide derivative beta-Ala-Pro-Dab-NHbenzyl may reduce wrinkles and sebum production in human skin by inhibiting dipeptidyl peptidase 4, suggesting potential for acne and skin inflammation treatment.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study analyzed the molecular evolution and functional divergence of the Dkk gene family, finding accelerated evolution in Aves and Reptilia and identifying functional differences that may impact hair follicle development via Wnt signaling inhibition.

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.

This study suggests that exosomes derived from dermal papilla cells, especially those cultured in three dimensions, promote hair growth and regeneration by enhancing follicular cell activity.

In this study, the methanol-ultrasound extract of Dendropanax morbifera leaf showed potential for use in functional cosmetics and hair growth products due to its high antioxidant capacity and effects on growth factor expression without cytotoxicity.

This study found that the Dongeui Hot Spring Water complex (Dongui Hot Spring Water CPX), containing sea slug extract and panthenol, demonstrated higher antioxidant activity and cell proliferation, suggesting potential benefits for preventing hair loss and improving scalp health.

This study found that dimethylarsinic acid significantly accelerates skin tumor development in hair follicle-targeted K6/ODC transgenic mice.

This study found that physoxia improved hair follicle functions in co-cultures of dermal papilla cells and melanocytes by enhancing their biological activities and promoting hair growth and pigmentation.

This review discusses the complex role of the EDA pathway in vertebrate skeletal development, emphasizing its interaction with other morphogenic pathways to influence skeletal diversity, but reports no new experimental results.

In laboratory conditions, this study found that the Dongeui Hot Spring Water Complex, containing sea slug extract, demonstrated enhanced antioxidant activity and promoted hair papilla cell proliferation compared to a control, suggesting potential benefits for scalp health and hair loss prevention.

This study found that ΔNp63α directly regulates VDR expression, which in turn may reduce invasiveness in an epidermoid cancer cell line.

This study found that hair regrowth occurred in 72.2% of alopecia areata patients treated with diphencyprone, with disease extent at baseline and duration affecting outcomes.

This study found that dermal papilla cells exhibit stage-dependent variation in histone methylation during the hair follicle cycle and display distinct chromatin marker expression when transitioning to in vitro culture.

This study found that the heat shock cognate protein Hsc70 was differentially expressed by dihydrotestosterone treatment in SV40-transformed dermal papilla cells, suggesting its involvement in androgen action on these cells.

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 study indicates that individuals exposed to PPD mount varying immune responses, with either tolerance, subclinical inflammation, or allergy, suggesting no true non-responders to PPD.

This study found hair regrowth in the majority of AA-affected mice and rats treated with diphencyprone, suggesting its potential utility for understanding human alopecia areata and the drug's therapeutic action.

In this retrospective case series, therapeutic responses to immunomodulatory and incretin-based therapies for Dercum's disease showed considerable individual variation, suggesting these treatments might be exploratory options when surgery isn't feasible, though further controlled studies are needed for definitive conclusions.

This study found that hypoxia increases the proliferation of dermal papilla cells and highlighted the important role of lactate dehydrogenase in this process.

This study determined that the incidence of Discoid Lupus Erythematosus at the Government General Hospital, Chennai, from 2006 to 2008 was 1.7 per 1000, with localized and disseminated forms manifesting distinctive demographic and clinical patterns.

In this study, BPA rapidly increased dendritic spine and synapse densities in cultured rat hippocampal neurons, with involvement of estrogen receptors and ERK1/2 and p38 pathways, but disrupted dihydrotestosterone's effects on synaptic plasticity.

This study reports that the dye peri-xanthenoxanthene (PXX) can act as an efficient photocatalyst for various radical reactions, including complex dual catalytic processes and the synthesis of an investigational drug intermediate.

In this study, hemp seed-derived exosomes (E40) showed potential for counteracting DHT-induced inhibition of feather follicle development in chicken embryos by modulating critical signaling pathways, suggesting a therapeutic approach for alopecia.

This study found that Diphenylcyclopropenone (DCP) was effective for treating extensive alopecia areata in Thai patients, although a high relapse rate suggests maintenance therapy might be necessary.

This review examines the physiological, biochemical, and molecular mechanisms by which DHEA and DHEA-S influence various bodily systems, citing rodent studies, but presents no new clinical results.
