• 70% of methylnitrosourea mice exhibit thymic lymphomas that increase the weight of the thymus by up to 10 times unlike wild-type mice that do not develop lymphomas in response to methylnitrosourea treatment
• in half of the affected mice, lymphomas infiltrate other organs
• in 2 methylnitrosourea-treated mice

endocrine/exocrine glands
• 70% of methylnitrosourea mice exhibit thymic lymphomas that increase the weight of the thymus by up to 10 times unlike wild-type mice that do not develop lymphomas in response to methylnitrosourea treatment
• in half of the affected mice, lymphomas infiltrate other organs
