In this study, researchers found that a high-fat diet in mice induced downregulation of certain Krtap genes in the tongue, which may be linked to structural issues or oral cancer risk, highlighting a potential connection between oral health and systemic diseases like metabolic syndrome.

In this study, treatments using a shampoo and conditioner with hematin helped repair damaged hair by depositing a cuticle-like structure, straightening hair as observed through electron microscopy.

Among adult male rats, this study found that combined exposure to lithium carbonate and lead acetate over 28 days led to synergistic cardiotoxic effects, evidenced by oxidative stress, ECG abnormalities, and molecular markers of increased apoptosis, despite no observable structural damage to myocardial tissue.

This review discusses the structure and function of the testes in male reproduction and development, noting the complex hormonal regulation within the hypothalamic-pituitary-gonadal axis but reports no new clinical results.

This review discusses the structural properties, pharmacological effects, and clinical applications of neurotoxins on synapses, reporting no new experimental results.

This review synthesizes both traditional and emerging molecular mechanisms of tissue remodeling across different organs, aiming to establish a theoretical basis for precision interventions in pathological conditions, according to the authors.

In this study, researchers characterized the retinal structure and function of the Oat^rhg mouse model of gyrate atrophy, finding localized atrophy without significant retina-wide functional impact, suggesting the model may be useful for testing new treatments using multimodal retinal imaging.

This review covers the structure, development, cycle, and molecular regulation of hair follicles but does not report new results, aiming to offer insights for addressing hair follicle-related diseases.

This review examines the potential of K18 as a diagnostic and prognostic marker in epithelial-derived tumors, highlighting its specific expression in tumor tissues and interaction with proteins involved in tumor progression, without reporting new clinical findings.

This review suggests that telocytes in male reproductive organs help organize tissue structure and paracrine factors, impacting organ development and pathology, but more research is needed on their molecular pathways.

This study suggests that variations in α-keratin proteins influence the structure and characteristics of wool fibers, indicating that keratin genes could serve as useful markers for identifying different wool traits.

This study identified a mutation in the CST6 gene linked to a rare syndrome with symptoms affecting hair and skin, revealing cystatin M/E's role in maintaining epidermal homeostasis and hair follicle development.

This study found that keratin and other hair proteins in humans are extensively modified posttranslationally, which helps explain the structural characteristics of mature hair.

This study found that targeting CISD1 with the compound NL-1 reduced mitochondrial dysfunction and reactive oxygen species accumulation, protecting against cisplatin-induced hearing loss in cell models and mice, without affecting cisplatin's cancer-fighting effectiveness.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.
