Effect of voluntary exercise on small intestinal tumor or serum levels of PGE2 in ApcMin/+ micea
| Group (N) | PGE2 levels (% decrease) | |
| Experiment 1 | ||
| Small intestinal tumors (ng/mg protein) | ||
| Control (11) | 12.7 ± 1.4 | |
| Exercise (10) | 8.8 ± 0.8b | (31%) |
| Experiment 2 | ||
| Serum (pg/ml) | ||
| Control (19) | 436.4 ± 103.6 | |
| Exercise (19) | 390.3 ± 111.7 | (11%) |
| Small intestinal tumors (ng/mg protein) | ||
| Control (13) | 26.5 ± 4.0 | |
| Exercise (13) | 20.5 ± 2.4 | (23%) |
aSamples from Experiments 1 and 2. PGE2 levels were determined in small intestinal tumor extracts and(or) serum samples by EIA. Values are mean ± SE of the number of samples (N) analyzed.
bp ≤ 0.05, two-tailed t-test.
