The gene expression of TNF-α showed approximately a 4-fold increase in the peritoneal cavity-endometriosis rat lesion models and approximately a 142-fold increase in the peritoneum-ectopic endometriosis rat lesion models compared with those in the control group (1.0 vs. 4.2; p < 0.0001; 1.0 vs. 141.9; p = 0.0008; Figure 6G and Figure 6H, respectively). The gene discussed is TNF; the disease is endometriosis.
