This report examines the mechanisms by which TCDD affects human epidermal and carcinoma cells, aiming to create a risk assessment model for halogenated aromatic compounds, but presents no new clinical results.

This study synthesized and evaluated five 6-mercaptopurine derivatives for anticancer activity against three cancer cell lines, detailing the promising results of compound 1.

Alpha-MSH affects mitochondrial function, and MC1R mutations may increase skin aging.

This review discusses the potential carcinogenic effects of anabolic androgenic steroids, particularly regarding Leydig cell tumors, and highlights the need for preventive information campaigns due to associated health risks.

This study concluded that there was clear evidence of carcinogenic activity of C.I. Acid Orange 3 in female F344/N rats but not in male rats or B6C3F1 mice of either sex.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This review discusses the role of mitochondria and evaluates methodologies for assessing mitochondrial function and toxicity, particularly in the context of HIV and antiretroviral treatments, but it reports no new empirical findings.

The researchers reported that the rat Hershberger assay reliably detected endocrine-disrupting effects of finasteride, procymidone, and 17α-methyltestosterone, validating the assay's sensitivity for identifying hormonal activity.

TCDD changes skin gene expression and may harm skin health.

In this study, oxidation hair dye formulations tested on mice showed no evidence of causing systemic toxicity or cancer over an 18-month period.

In this study, NM exposure in mouse skin disrupted pilosebaceous units, initially decreasing markers of sebum production and cellular division, but showed signs of healing and marker recovery by day five.

This review introduces pharmacophore technology and discusses its applications in toxicity prediction and limits, but reports no new clinical results.

This study found that chemically induced skin tumors in mice predominantly originated from Lgr6 + and/or Lrig1 + stem cells of the upper hair follicle rather than from other stem cell populations.

In this study, activation of c-MycER in adult mouse epidermis rapidly induced proliferation and disrupted keratinocyte differentiation, causing changes similar to precancerous lesions, which regressed once c-MycER was deactivated.

This study found that a single application of TCDD on the skin of hairless mice altered epidermal differentiation, changing keratin expression patterns similarly to a known tumor promoter.

This study suggests that combining bendamustine with tucidinostat may improve survival in patients with relapsed or refractory adult T-cell leukemia/lymphoma, highlighting its potential for clinical investigation.

This study found that overexpression of PKCɛ in mouse epidermis increased sensitivity to metastatic squamous cell carcinoma, suggesting that a PKCɛ-mediated microenvironment may promote cancer development through specific cytokines like TNFα.

This study reports that transgenic mice carrying Clone B DNA developed spontaneous melanomas likely due to an interruption in genes regulating cell growth in melanin-producing cells, offering a model for melanoma research.

This study observed that Wistar rats on a zinc-deficient diet had a higher incidence of stomach cancer when exposed to MNNG, suggesting zinc deficiency may increase cancer risk.

The research found that while Dnmt3a and Dnmt3b are not necessary for skin homeostasis in mice, the loss of Dnmt3a increases squamous tumor formation from carcinogens, and combined deletion of both results in more aggressive and metastatic tumors.

This study found that among Indian rheumatoid arthritis patients, the MTHFR A1298C polymorphism was associated with varying responses to methotrexate, with 1298CC genotypes showing higher toxicity and poorer efficacy compared to 1298AA genotypes.

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 identified a series of novel β-glucuronidase inhibitors that may help mitigate adverse effects of first-line anti-cancer drugs by targeting gut bacteria, based on virtual high-throughput screening findings.

UV radiation may cause DNA changes in skin, certain UVB therapy helps psoriasis, a new gene mutation is linked to mild piebaldism, different immune cells affect psoriasis, a drug promotes hair growth, and some cancer drugs could treat skin barrier issues.

In this case study, researchers reported on a 54-year-old woman who developed methotrexate toxicity after mistakenly taking high doses over five days, which led to mucocutaneous lesions and pancytopenia, highlighting the importance of early recognition and treatment of such toxicities.

In this study, activation of oncogenic K-ras in a mouse model caused the oral mucosa to rapidly progress from squamous hyperplasia to carcinoma within 14 days, demonstrating its acute sensitivity.

This study found that mice with a mutation in the Zdhhc13 gene exhibited increased susceptibility to skin cancer, highlighting a potential protective role of palmitoyl acyltransferase in skin carcinogenesis.

This study found that the crude extract of Hibiscus rosa-sinensis leaves, whether irradiated or not, showed significant antioxidant activity without causing toxicity in rats, suggesting gamma radiation may enhance its therapeutic properties.

This study found that maternal exposure to artificial food coloring additives altered the expression of CYP1A1, various glutathione S-transferases, and VEGF in rat skin, which could influence skin disease development.

In this study on Danio rerio, researchers found that exposure to titanium dioxide nanoparticles did not affect embryonic development but altered the structure of male gonads, acting as potential endocrine disruptors with androgenic activity.
