Uncovering P53 Mutations And Abnormal Gene Expression In Pediatric Adrenocortical Cancer, Alina Nico West

Theses and Dissertations (ETD)

Pediatric adrenocortical cancer is extremely rare and often fatal (approximately 0.3-0.4 cases per million worldwide; 50% 5-year survival). The incidence of pediatric adrenocortical cancer in southern Brazil is 10-15 times higher than the worldwide incidence. Due to the rarity of adrenocortical cancer, especially in children, underlying gene dysregulation and mechanisms of tumorigenesis of the adrenal gland are very poorly described in the literature. However, it is well-known that the tumor suppressor p53, which is mutated in over 50% of all human cancers, is commonly mutated in pediatric adrenocortical cancer. In addition, evidence strongly suggests that if a child has adrenocortical …
