This review investigates how the chirality of peptides affects their ability to form hydrogels, comparing the structural and mechanical properties of hydrogels made from homochiral and heterochiral peptides, and discussing their potential biological applications.

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 Epstein-Barr virus infection upregulated a truncated variant of human basic hair keratin 1 (hHb1-ΔN) in gastric carcinoma cell lines, suggesting a possible link to carcinoma differentiation.

This review discusses the role of enhancers and super-enhancers in tissue-specific gene regulation and cancer development, and it reports no new experimental results.

In this study, cell membrane remodeling with a thermoresponsive boronic acid copolymer was shown to rapidly form spheroids from cancer or cardiac cell lines under standard conditions, promising advances in tissue engineering.

This study found that inducing Atoh1 expression in transgenic mice is sufficient to generate new Merkel cells in the epidermis, with variations by skin location, developmental age, and hair cycle stage.

In a mouse model of infected burns, this study found that treatment with recombinant fusion peptide EK significantly decreased Pseudomonas aeruginosa colony count and improved wound healing rates compared to controls.

This study found that human epidermal keratinocytes express a functional μ-opiate receptor at both the mRNA and protein levels, potentially playing a role in skin physiology and pathology.

This study found that selective inactivation of ribonucleotide excision repair in mouse epidermis led to spontaneous DNA damage, skin inflammation, and the development of squamous cell carcinoma, suggesting potential implications for cancer development in humans.

This article discusses various disorders of the hair erector muscle, compiling conditions that involve it passively or actively, but reports no new clinical findings.

This study found that epitestosterone acts as a weak antiandrogen by inhibiting receptor binding and 5α-reductase activity in animal models.

Healing psoriatic plaques can cause unexpected hair growth.

This article reviews recent research on adult epidermal stem cells, discussing their properties and potential for reprogramming into patient-specific therapies, and emphasizes the need for further development while minimizing cancer risk.

This study found that the HS III element in the K14 gene's regulatory sequence promotes gene expression in inner root sheath keratinocytes, highlighting cooperative interactions in keratinocyte-specific gene regulation.

Diphenyl ethers can potentially reduce excess oil production when applied on the skin, helping treat conditions like acne.

This study found that topical rebamipide, originally a gastric ulcer medication, can activate hair follicle stem cells and promote hair regeneration by modulating dermal adipocyte metabolism, with potential targeting of the prostaglandin E receptor EP4.

The study observed that mRAGE expression is prevalent in keratinocytes of the healthy human epidermis and may regulate inflammation and apoptosis to maintain skin homeostasis rather than responding to aging processes.

This study suggests that hemoglobin α expression in the epidermis is induced by oxidative stress and may function as an antioxidant, contributing to skin barrier function.

This study observed that targeted expression of the neu oncogene in transgenic mice led to significant epidermal hyperplasia and a carcinoma-like appearance, suggesting a crucial role for erbB2 signaling in epidermal proliferation and carcinogenesis.

This case report describes a rare instance of dermographic urticaria triggered by an 810 nm diode laser for hair removal, with symptoms managed effectively by pre-treatment with levocetirizine.

This study found that a cuticle keratin gene in sheep is a pseudogene due to gene duplication and mutations, lacking expression in vivo.

This study developed keratin-based hydrogels with improved water solubility and tunable properties, demonstrating excellent cytocompatibility, suggesting potential for biomedical applications.

This study found that Hairless (HR) and putrescine form a negative regulatory network that impacts epidermal homeostasis and hair follicle cycling, linked to the MYC superfamily's regulation of ODC expression.

This study identified epiprofin as a highly tissue-specific nuclear protein that promotes cell proliferation, mainly expressed in the developing teeth, hair follicles, and limbs of embryonic mice.

In this study, researchers found that the loss of SETDB1 in epidermal keratinocytes led to altered chromatin states, increased ERV expression, and activation of immune responses, while inhibiting these effects with certain antiviral drugs reduced skin inflammation and hair loss in a mouse model.

This study found that treating skin wounds with a combination of epidermis-derived epithelial-like stem/progenitor cells and platelet-rich plasma improved tissue repair and increased vascularization and elastin content compared to platelet-rich plasma alone.

This study identified thyrotropin-releasing hormone (TRH) as a stimulant of wound healing in both frog and human skin models, suggesting it as a potential neuroendocrine wound repair promoter.

This study found that adult mouse dermis can be reprogrammed by epidermal cues to resemble neonatal dermis, with changes in fibroblast proliferation and extracellular matrix composition.
