Task: Intent Identification
Input (English): Uterine infection occurs in as much as 20% of preterm labor and results in increased decidual cytokines. The objective of this study was to examine the effect of interleukin-1 (IL-1) and the cyclooxygenase-2 (COX-2) inhibitor, NS-398, on myometrial prostaglandin (PG) production and COX-2 expression.', 'Human uterine myocytes were stimulated with IL-1 (0-50 ng/mL) over 24 hr. PGE2, PGF2alpha, and 6-keto F1alpha were measured by enzyme-linked immunosorbent assay. Both COX-1 and COX-2 proteins and mRNA were measured by western and northern blot, respectively.', 'IL-1 increased PG production beginning at 6 hr, COX-2 protein increased beginning at 4 hr and continued to increase at 24 hr. COX-2 mRNA increased at 2 hr and peaked at 4 hr. NS-398 blocked PG production but had no effect on COX-2 protein or mRNA.
