-Differential promoter activity-LEF1 is a new type of target gene ectopically activated in colon cancer. The pattern of this ectopic expression is unusual because it derives from selective activation of a promoter for a full-length LEF1 isoform.

-Differential promoter activity-LEF/TCF expression and activity in normal intestine and colon carcinomas suggests that the relative amounts of LEF/TCF isoforms may change as tumors progress and this may influence the strength and specificity of Wnt signals in the nucleus.

Immunohistochemistry, tissue microarray, univariate and multivariate analysisUp-regulation-LEF-1 expression was found in 56 (26%) and TCF4 expression in 99 (46%) of colorectal carcinomas and both were heterogeneously distributed throughout the tumours.

LEF-1 expression as well as a LEF-1/TCF4 ratio were positive prognostic factors and correlated with longer overall survival

Gene Type protein coding
Gene Family -
Description This gene encodes a transcription factor belonging to a family of proteins that share homology with the high mobility group protein-1. The protein encoded by this gene can bind to a functionally important site in the T-cell receptor-alpha enhancer, thereby conferring maximal enhancer activity. This transcription factor is involved in the Wnt signaling pathway, and it may function in hair cell differentiation and follicle morphogenesis. Mutations in this gene have been found in somatic sebaceous tumors. This gene has also been linked to other cancers, including androgen-independent prostate cancer. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]
