♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
premature death ( J:218222 )
• mice exhibit significantly increased survival time relative to mice that are homozygous for Ptentm1Hwu and heterozygous for Pgrtm2(cre)Lyd, with >50% of mice still viable at 64 weeks of age
• mice do not die due to the development of endometrial cancer

reproductive system
endometrium hyperplasia ( J:218222 )
• mice exhibit endometrial hyperplasia at 2 months but not at 3 months of age
• however, endometrial adenocarcinoma with invasion into the myometrium is not observed due to inhibition of ERK1/2 phosphorylation
increased uterus weight ( J:218222 )
• at 3 months of age, mice show a significantly reduced increase in uterine/body weight ratio relative to mice that are homozygous for Ptentm1Hwu and heterozygous for Pgrtm2(cre)Lyd
abnormal uterus physiology ( J:218222 )
• at 2 months of age, mice show a significantly reduced uterine epithelial cell proliferation relative to mice that are homozygous for Ptentm1Hwu and heterozygous for Pgrtm2(cre)Lyd

neoplasm
increased papilloma incidence ( J:218222 )
• mice develop vaginal papillomas
