To understand the role of prostaglandin (PG) receptor EP2 (Ptger2) signaling in ovulation and fertilization, we investigated time-dependent expression profiles in wild-type (WT) and Ptger2-/- cumuli before and after ovulation by using microarrays. We used Affymetrix U74A ver2 microarrays to investig...
