HMGA1-P6 and HMGA1-P7 mRNA expression pattern in endometrioid endometrial adenocarcinomas (EEC). Correlation of HMGA1 mRNA expression with those of HMGA1P6 and HMGA1P7 and evaluation of their expression, according to clinicopathological characteristics, by qRT-PCR. HMGA1P6 and HMGA1P7 gene expression was performed in six normal endometrial samples, 10 EEC samples from stage IA, 10 from stage IB, 10 from stage II, 10 from stage III and six samples from stage IV, and the (A) correlation between HMGA1 and HMGA1P6, (B) HMGA1 and HMGA1P7 and (C) HMGA1P6 and HMGA1P7 mRNA levels was evaluated. (D) HMGA1P6 and (E) HMGA1P7 mRNA expression distribution in the different tumor staging groups analyzed. Statistical analyses were performed based on a confidence interval of 95%. Data with p < 0.05 were considered statistically significant. * = p < 0.05.
