Expression of MADDAM mRNA in human cell lines and tissues.

(A) Human cell lines; (B) tissues. The commercially available tissue blot contained poly(A)⁺RNA of the indicated tissues (Multiple tissue Northern blot II; Clontech). Northern blot analysis was performed as described “Materials and methods.” As a control for RNA loading, membranes were rehybridized with an 18S rRNA- (A) or GAPDH-oligonucleotide (B).
