In this case study, electron microscopy revealed that harlequin ichthyosis involves giant mitochondria in keratinocytes and abnormal lamellar granule development, which may contribute to pathogenesis through altered lipid metabolism.

In this study, researchers found that a positive feedback loop involving Ca 2+ and RHD2 NADPH oxidase-derived ROS helps maintain growth sites, crucial for root hair development and cell shape in Arabidopsis thaliana.

This study found that increased ACE2 expression, prompted by mechanical stretch, promotes skin regeneration and reduces dermal thinning during tissue expansion by enhancing collagen synthesis, suggesting ACE2's potential to improve clinical outcomes in reconstructive surgery settings.

This study suggests that the harlequin ichthyosis mouse model closely resembles human type 2 harlequin ichthyosis, indicating its potential as a useful model for studying the human condition.

This study identified that Eda-A1 unexpectedly induces placode inhibitors dkk4 and lrp4, indicating the importance of tightly regulated signaling for proper ectodermal organ development.

This study identified a new keratin, K6irs, as a potential histological marker for the inner root sheath of hair follicles in mice and humans, and as a candidate gene for hereditary hair defects.

This report documents a 14-year-old Chinese boy with mitochondrial encephalopathy, lactic acidosis, stroke-like episodes, and a de novo A3243G mitochondrial DNA mutation, highlighting the condition's multisystem involvement without ragged red fibers in muscle biopsy.

A new mouse mutation causes skin and hair issues, influenced by another gene.

This case report documents the first known instance of erythromelanosis follicularis faciei in a Saudi male, detailing its clinical and histopathological characteristics.

In this study, researchers used a mouse model to demonstrate that expression of MARCKSL1 in dendritic cells plays a crucial role in modulating fibrotic responses and scar formation during wound healing, suggesting that targeting this expression could offer new therapeutic strategies for scar prevention.

This article discusses aspects of Graham-Little syndrome, including follicular keratosis with cicatricial alopecia, and offers no new clinical findings.

This study concludes that SPARC is likely a secondary response during the hair cycle's transitional phases, indicating tissue-remodeling processes similar to those in wound repair, rather than initiating these transitions.

This case report describes a patient who developed PRIDE syndrome-associated skin issues, including a pruritic papulopustular rash and alopecia, after starting treatment with the EGFR inhibitor erlotinib.

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 study identified a new PNPLA1 mutation in a Spanish family with autosomal recessive congenital ichthyosis.

This study found that cupric chloride treatment may partially correct delayed maturation and abnormal arborization of Purkinje cells in the cerebellum of hemizygous brindled mice, a model for Kinky hair disease.

This case study reports a 36-year-old man with KID syndrome caused by an N14Y GJB2 mutation, expanding the mutation spectrum of this condition in the Chinese population.

In this study, autologous micrografting technology using auricular cartilage was reported to be safe and effective for improving knee function and reducing symptoms in patients with early-stage knee osteoarthritis over six months, but larger studies are needed to confirm these results.

EDA2R gene linked to hair loss.

This study observed that the compound EM-402 reduced 5α-reductase activity and sebaceous gland size in the flank organs and ears of hamsters, indicating potent localized anti-androgenic effects without systemic action.

This study found that the FER/MLO signaling module plays a crucial role in calcium oscillations and ROS production in root hair tip growth, with the MLO15 protein regulating these processes and restoring disrupted growth and signaling in fer mutant root hairs.

In this first reported case, a 42-year-old female with Parry Romberg Syndrome was treated using hyaluronic acid filler, which the authors suggest may serve as a safe, simple, and cost-effective alternative to more complex surgical methods.

This study reported that dandelion herb-derived carbon dots significantly enhanced wound healing in mice with Staphylococcus aureus infections, outperforming a commercial wound healing spray through their antibacterial and dual ROS-modulating capabilities.
