Those mouse models present pervasive EMC at a young age, without the presentation of other cancers. In 2008, Takiko Daikoku, in our division, created mouse models with conditional deletion of endometrial PTEN, conditional deletion of endometrial p53, and combined deletion of both genes. p53 mutant mice develop many types of cancer, making it difficult to specifically study EMC. Homozygous mutation of PTEN in mice results in embryonic lethality, though 20 percent of heterozygous models expressed EMC by 10 months. Mouse models are invaluable in studying the development and progression of the disease, but until recently models were imprecise. Genetic mutations affecting the phosphatase and tensin homologue (PTEN) gene are observed in the majority of EMC type I cases, while genetic mutations of p53 are found in the majority of EMC type II cases.
PTEN and uterine carcinoma: conditionally gene-deleted mouse models.Įndometrial cancer (EMC) affects 40,000 US women per year, leading to 7,000 deaths. These results could also include sensitive or difficult to understand information such as your baby’s gender, STD testing or cancer related biopsy results. You may want to wait a few days to hear from your provider before messaging them. We also demonstrated that aspirin, a nonselective Cox inhibitor, compromises PPARδ function, providing a possible treatment option. Results are promptly made available to you in M圜hart, so you may see them before your provider does.
Our lab has shown that PPARδ is highly expressed in both mouse and human EOC tumors and that inhibiting PPARδ activity can reduce tumor growth. Similarly, mouse models of EOC exhibit overexpression of Cox-1 and PGI2.īoth PGI2 and PGE2 can interact with PPARδ, which has been implicated in tumorigenesis (although the pathway is unclear). We showed that human EOC overexpresses Cox-1, generating PGI2 and PGE2 as major prostanoids. Cox-2 is implicated in a variety of cancers, but until recently, the role of Cox-1 was unclear. Little is known about the early stages of the disease and the underlying causes, making it difficult to diagnose EOC in a timely manner. Indeed, EOC is the fourth-leading cause of cancer death in the United States.
