N-Nitroso-N-methylurea (NMU; 5 μM) treatment increases the cellular NF-κB activity in human malignant keratinocytes. N-Nitroso-N-methylurea also increases the amount of I-κBα phosphorylation.
N-Nitroso-N-methylurea (NMU) gives intravenously to rats at age 50 days induced mammary carcinomas in 89% of BUF/N, 73% of Sprague-Dawley, and 89% of F344 females. Latent periods are, respectively, 77, 86, and 94 days. Doubling times of NMU-induced primary and transplanted carcinomas are similar to 7 days. Cachexia ensues at the 5th week from the onset of the first tumor. When the tumor is larger than 15 g, hypercalcemia is usually observed.
