RESUMEN

Objetivo. Evaluar el efecto in vitro del ácido linoléico sobre la producción de PGF2α y PGE2 en células endometriales epiteliales bovinas (CEEP). Materiales y métodos. Se cultivaron CEEP aisladas de tejido uterino y se suplementaron con AL a diferentes concentraciones (1 μM, 10 μM, 100 μM), oxitocina (OT) (0.1 μM) e interferón trofoectodérmico bovino (bINT-τ) (50 ng/ml). Se cuantificó la PGF2α y PGE2 a distintos tiempos (12, 24 y 36h). En el control, la PGF2α en el sobrenadante aumentó en el tiempo de cultivo y fue 1.2 veces mayor que la producción de PGE2. Resultados. El ácido linoléico disminuyó la concentración de PGF2α (p<0.05) en el sobrenadante, y no afectó (p>0.05) la producción de PGE2. El efecto conjunto de AL y OT sobre la producción de PGF2α difirió para cada uno de los tiempos; el ácido linoléico inhibió parcialmente el efecto estimulante de la OT sobre la producción de PGE2, el efecto conjunto del AL y el bINT-τ aumentó (p<0.05) esta inhibición hasta la hora 24. Conclusiones. El ácido linoléico afecta negativamente la concentración de PGF2α en el sobrenadante a través del tiempo. Respecto a la PGE2 se concluye que el ácido linoléico por sí solo no afecta la concentración en el sobrenadante.
