In this study, researchers found that stabilizing the protein HIF1A in hair follicles promotes glycolysis over oxidative phosphorylation, potentially reducing oxidative stress and supporting hair growth.

This study proposed a hypothesis for cutaneous calcinosis, suggesting that feeding DHT and subsequent epilation lead to ATP release and calcium orthophosphate formation, initiating calcification in rats.

This study found no evidence of increased keratinocyte proliferation in acne vulgaris, suggesting that other mechanisms may be responsible for hyperkeratinization in acne pathogenesis.

This study found that treating reconstructed human epidermis with beta-lipohydroxy salicylic acid increased tight junction remnants in the stratum corneum, potentially affecting skin cohesion and desquamation.

This narrative review discusses the discovery of plasticity in epidermal stem cells using single-cell transcriptomics, but reports no new results; it highlights the potential implications for regenerative medicine.

This study found that activating the erbB-2 oncogene in transgenic mice led to severe skin abnormalities and fatal defects, indicating erbB-2's significant role in skin and hair follicle development.

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.

This study found that hydrophobic amino acids from egg white hydrolyzed protein and L-phenylalanine effectively penetrate deep into the human hair fiber, increasing specific contents in both virgin and bleached hair.

This study found that keratin-75, discovered in enamel tissue, is secreted by ameloblasts using an unconventional pathway involving the ER-Golgi-Intermediate-Compartment and Golgi, differing from typical cytokeratin localization.

This study found that in male rat hippocampal slices, DHT is necessary for low frequency stimulation-induced long-term depression, while E2 synthesis is essential for high frequency stimulation-induced long-term potentiation.

In this review, researchers highlighted the pivotal role of the epicardium in heart regeneration and repair, particularly through its cellular programs and signaling during myocardial infarction, though they noted challenges in replicating these processes in nonregenerative mammals, suggesting pathways for innovative cardiovascular therapies.

This study developed a rapid, cost-effective three-dimensional skin equivalent model using human dermal fibroblasts, collagen, and hair follicles, which closely resembles natural human skin and can be used for autologous transplantation.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

This case report found that topical bimatoprost in a female Hispanic patient with glaucoma led to increased hair growth and pigmentation in the malar region, which resolved after discontinuing use and epilation.

This study found that polyamines enhance genome integrity by facilitating homologous recombination-mediated DNA repair, suggesting a novel role for polyamines beyond promoting cell growth and proliferation.

This study found that isolated human scalp hair follicles express PGE2 genes and EP2 protein, suggesting PGE2 may play a crucial role in regulating hair growth.

This study observed that in chicken skin, large-scale differences in gene expression between feathered and scaly skin are controlled by enhancer-driven uniform expression, while small-scale differences within individual feathers are associated with chromatin looping.

In this study, researchers explored how hair follicle orientation is affected in the rosette fancy mouse and found that a mutation in the PCP gene Fzd6 caused reversed hair orientations in the posterior region, leading to the formation of unique whorls.

Hair proteins change location and structure as hair cells mature.

In this study, the presence of the HPV11-E2 protein in transgenic mice was found to increase and vary the expression of a reporter gene in hair follicle bulge regions.

This study found that subthermal CRET treatment increased keratinocyte proliferation and modulated cytokine production, affecting the inflammatory response in human keratinocytes through EGFR and ERK1/2/NF-κB pathways.

This study found that mirex and TPA promote papilloma formation in CD-1 mouse skin through distinct populations of mutant Ha-ras cells, resulting in additive tumor yields.

In this study, synchrotron-powered infrared microscopy revealed that hair follicles are a favored penetration pathway for cyanophenol and ethylhexyl methoxycinnamate in human skin, without altering protein secondary structure.

This study found that human skin expresses proenkephalin, whose expression is upregulated by environmental stress and varies in pathological conditions, increasing in psoriasis and decreasing in melanocytic tumors.

In this study, dynamic hyaluronic acid hydrogels with properties like injectability and controlled degradation were developed to enhance healing and remodeling of diabetic wounds, achieving effects such as inflammation reduction, increased angiogenesis, and neovascularization, leading to complete wound healing.

Photocrosslinkable biomaterials can improve wound healing by controlling mechanical environments.

This study found that estetrol (E4) significantly prolonged the anagen phase and increased hair matrix keratinocyte proliferation in cultured human hair follicles, suggesting its potential as a treatment for female pattern hair loss.

This study found that regulatory sequences crucial for inducing K6a expression in response to epidermal injury are located in specific upstream regions of the K6a gene in transgenic mice.

This review highlights new perspectives in genomics and epigenomics for skin rejuvenation, comparing innovative strategies like senolytics and DNA repair modulators with classical treatments, and emphasizing the importance of tailoring therapies using individual genomic profiles for personalized anti-ageing approaches.

This case report describes a postmenopausal woman who experienced facial erythema, acne, and hirsutism due to excess androgen and estrogen levels.
