This study identified and sequenced several keratin cDNA clones showing distinct expression patterns in mouse epithelia, with in situ hybridization highlighting differences in keratin distribution between normal and hyperproliferative tissues.

In this study, researchers identified two new keratin-associated proteins, hKAP1.6 and hKAP1.7, in human hair follicles, contributing to understanding hair fiber differentiation.

Cathepsin L deficiency causes hair and skin issues in mice.

This study identified a compound heterozygous mutation in a hairless rhesus macaque, which was associated with skin abnormalities similar to those in hairless mice and humans with APL.

This case study of a 45-year-old man from Tonga describes the identification of pachyonychia congenita through genetic testing, revealing a mutation in the keratin gene KRT16, associated with chronic painful skin and nail conditions.

This study found that certain CYP21A2 mutations significantly reduce enzyme activity, contributing to non-classic congenital adrenal hyperplasia phenotypes, which may aid in enhancing diagnosis and treatment strategies.

This study found that Clitocybin A from Clitocybe aurantiaca significantly increased the proliferation of immortalized rat dermal papilla cells, suggesting potential hair growth-promoting effects in a laboratory setting.

Confocal Laser Scanning Microscopy (CLSM) is a useful tool for studying how drugs interact with skin and diagnosing skin disorders, despite some limitations.

In this study, researchers analyzed skin tumors from patients with CYLD cutaneous syndrome and found that loss of CYLD function is linked to changes in cellular signaling pathways, particularly NF-κB signaling, and leads to increased secretion of specific extracellular matrix proteins.

This study identified a high-risk allele in the PLCD1 gene associated with hereditary trichilemmal cyst formation, proposing a monoallelic two-hit mechanism as the underlying genetic pathogenesis.

This study identified a nonsense mutation in the Sgkl gene as the cause of defective hair growth in a mutant mouse strain, implicating the SGKL signaling pathway in hair development.

This study on Indian dromedary camel breeds investigated the KRTAP7 protein, finding all four breeds shared an identical gene sequence, with 13 phosphorylation and glycosylation sites influencing hair characteristics, alongside predicted interactions with other biosynthesis-related proteins.

In this study, DataDerm revealed that from 2016 to 2022, a majority of patients diagnosed with keratinocyte carcinoma were male, predominantly white, and commonly between 56-75 years old, with most living in urban areas and having a history of non-melanoma skin cancer.

This study identified the expression sites of five KAP5 genes on human chromosome 11q13.5 in scalp skin sections but did not explore their detailed distribution within hair follicles.

This study found that reported stress and hair growth changes related to facial/body hair excess or scalp hair loss differ among ethnic gender minority groups, with black and other ethnic respondents experiencing more stress compared to Caucasians, particularly in relation to facial/body hair excess.

This study provided the first X-ray crystal structure of the mammalian steroid hormone reductase AKR1D1 and identified a disease-related mutant, P133R, which may impact bile acid metabolism and cause clinical symptoms.

In this case study, a transition to the MEK inhibitor trametinib successfully stabilized disease and reduced toxicity in a patient with refractory kaposiform lymphangiomatosis after prolonged sirolimus and steroid treatment.

This study found that dermoscopy is valuable for diagnosing facial actinic keratosis in Chinese patients, with specific patterns like red pseudonetwork and follicular plugs suggesting its utility in differential diagnosis.

This study observed that dalpiciclib is associated with fewer adverse events like diarrhea and hepatotoxicity compared to other CDK4/6 inhibitors, potentially offering better patient-perceived safety and quality of life.

This review discusses central centrifugal cicatricial alopecia, its similarities to lichen planopilaris, and emphasizes the need for further research due to its underdiagnosis and impact on African-descended women.

This study found that phenyl-imidazole sulfonamide derivatives, particularly ISCK03, inhibited c-kit signaling and promoted depigmentation in various experimental settings, suggesting potential use as skin-whitening agents.

In this study, researchers evaluated CS12192, a selective JAK3 inhibitor, in an alopecia areata mouse model and found it reversed hair growth inhibition comparably to baricitinib, with better safety and similar immune-modulating mechanisms.

This study found that the DKK3-CKAP4 signaling axis is involved in fibroimmune remodeling in androgenetic alopecia and that targeting this pathway may restore a regenerative hair follicle environment, offering a potential therapeutic strategy to counteract hair follicle miniaturization.

This study investigated a nanostructured system using PS-b-PAA diblock copolymer for incorporating the hydrophobic photosensitizer ClAlPc, finding it effective in causing cellular damage in Caco-2 cells under light while demonstrating no cytotoxicity without light, suggesting its potential use in photodynamic therapy.

This study introduced the C-CAT, a new assessment tool for central centrifugal cicatricial alopecia, and found that established treatments improved symptoms in most patients over six months.

In this randomized, placebo-controlled study, Kūlaris supplementation significantly improved quality of life for participants with mild-to-severe acne over 12 weeks, though no significant changes in general skin health measures were observed compared to placebo.

This study found that KSR1 is essential for v-Ha-ras-mediated skin tumor formation in mice but not for MT-driven mammary tumor genesis, suggesting its potential as a therapeutic target in Ras/MAPK signaling.

This study developed and evaluated a photographic scale to assess CCCA pattern and severity in African American women, finding it reproducible when used by investigators and participants.
