| Expression of Catenin family members CTNNA 1 , CTNNA 2 , CTNNB 1 and JUP in the primate prefrontal cortex and hippocampus . ^^^ We have used in situ hybridization to determine the cellular expression patterns of four members of this family , Alpha E , Alpha N , Beta , and Gamma catenins ( CTNNA 1 , CTNNA 2 , CTNNB 1 , and JUP respectively ) in the adult primate dorsolateral prefrontal cortex ( DLPFC ) and hippocampus . ^^^ CTNNA 2 , CTNNB 1 , and JUP mRNAs were detected in all layers of the DLPFC and in all neuronal subregions of the hippocampal formation , however CTNNA 1 mRNA , coding for an ' epithelial ' specific catenin , was not detected in any region of the cortex or hippocampus . ^^^ |
