Figure 4.

Relative gene expression in myometrial tissue from mice receiving 20 μg lipopolysaccharide (LPS) by either single proximal injection (SPI) or double distal injection (DDI), compared with mice receiving saline sham injections. Gene expression was normalized to ribosomal phosphoprotein P0 expression and is displayed as the relative expression compared with the saline sham group. Tissue was collected 8 hours after surgery. Data are expressed as means ± SD. n ≥ 6 per group. *P < 0.05, **P < 0.01, and ***P < 0.001. COX2, cyclooxygenase 2; CX43, connexin 43; HPGD, 15-hydroxyprostaglandin dehydrogenase; OXTR, oxytocin receptor; TNF-α, tumor necrosis factor-α.
