Immunohistochemical expression of phosphorylated S6 ribosomal protein and serine phosphorylated IRS-1 in normal proliferative endometrium, endometrial CAH and endometrial endometrioid carcinoma, grade 1. All of these tissues expressed IRS-1 and/or IRS-2. Results are expressed as the number of cases with 2+ or 3+ immunohistochemical expression (n; %). Correlation between expression of phospho-(S235) S6 and phospho-(S636/639) IRS-1 was determined by Pearson’s correlation (p<0.025). * Statistically significant as compared to normal endometrium at the p<0.001 level by χ2-analysis.
Group | Phospho-(S235) S6 | Phospho-(S636/639) IRS-1 |
---|---|---|
Normal (n=6) | 1 (17%) | 6 (100%) |
CAH (n=25) | 24 (96%)* | 5 (20%) |
EEC Grade 1 (n=10) | 9 (90%)* | 2 (18%) |
statistically significant as compared to normal endometrium at the p<0.001 level by x2-analysis.
