TCF7L1 and neoplasm: Detailed pairwise analysis of these prominent differences between TCF7L1- and TCF7L2-correlation in normal tissue suggests a stronger association of TCF7L1-correlated transcripts with the extracellular matrix, and a stronger association of TCF7L2-correlated transcripts with cell junctions and cell adhesion; but interestingly, in tumor tissue TCF7L1 expression is more strongly correlated with transcripts associated with cell adhesion; and also with angiogenesis.
