FIG. 3.

High levels of xN-CoR gene transcripts are present during intestinal remodeling (A), tail resorption (B), and hindlimb morphogenesis (C). Each lane had 10 μg of total RNA, except for stage NF64 tail and stage NF56 hindlimb, which contained 5 μg. The same blot was probed with either an 800-bp xN-CoR cDNA fragment corresponding to aa 1992 to 2265 or the loading control gene rpl8, whose expression remains constant during development (44, 45, 58). The signals from the blots were quantified with a PhosphorImager and plotted on the right after normalization against the control rpl8 signals. The data represent one of two independent experiments with similar conclusions.
