Fig. 8From: Divergent activity of the gonadotropin-releasing hormone receptor gene promoter among genetic lines of pigs is partially conferred by nuclear factor (NF)-kB, specificity protein (SP)1-like and GATA-4 binding sitesThe NF-κB subunits p52 and p65, but not p50 are present in αT3-1 nuclear extracts. Western blot analysis was performed with αT3-1 nuclear extracts (40 μg) and antibodies specific for the a p50 b p52 and c p65 subunits of NF-κB as described in Materials and Methods Back to article page
