TCF7L1 and neoplasm: Since both TCF7L1 and TCF7L1ΔN increased tumor growth, suppressed senescence, and stimulated cell migration much more significantly than TCF7L1ΔG and TCF7L1*, we sought to identify the global change in gene expression caused by the overexpression of TCF7L1 and TCF7L1ΔN and less so by the overexpression of TCF7L1ΔG and TCF7L1*.
