Department of Molecular Biology and Biochemistry, UCI Institute for Immunology, University of California Irvine, Irvine, California, USA
PLoS ONE 4:e7841. 2009..Both rac1 and c-jun have recently been implicated in wnt signaling, however their upstream activators have not been identified...
A role for YY1 in repression of dominant negative LEF-1 expression in colon cancerNoriko N Yokoyama
Department of Microbiology and Molecular Genetics, University of California, Irvine, Irvine, CA 92697, USA
Nucleic Acids Res 38:6375-88. 2010..We also show that induced expression of dnLEF-1 in colon cancer cells slows their rate of proliferation. We propose that YY1 plays an important role in preventing dnLEF-1 expression and growth inhibition in colon cancer...
hADA2a and hADA3 are required for acetylation, transcriptional activity and proliferative effects of beta-cateninMin Yang
Department of Medicine, University of California, Irvine, California, USA
Cancer Biol Ther 7:120-8. 2008..Our studies identify hADA2a and hADA3 as crucial cofactors of beta-catenin that are likely involved in the assembly of transactivation-competent beta-catenin complexes at Wnt target genes...

Department of Microbiology and Molecular Genetics, University of California, Irvine, Irvine, CA 92697, USA
Sci Signal 1:pe43. 2008..A recent study uncovered a new mode of repression of Wnt target genes in which recognition of a novel DNA element by TCF specifies that beta-catenin acts as a transcriptional repressor...
NOTCH signaling is required for formation and self-renewal of tumor-initiating cells and for repression of secretory cell differentiation in colon cancerShaheen S Sikandar
Department of Biological Chemistry, School of Medicine, University of California, Irvine, California, USA
Cancer Res 70:1469-78. 2010..Our findings describe a novel human cell system to study NOTCH signaling in CRC tumor initiation and suggest that inhibition of NOTCH signaling may improve CRC chemoprevention and chemotherapy...
Research Grants
- Wnt signaling in Colon CancerMarian Waterman; Fiscal Year: 2009..Collectively, the work proposed will address important unknowns about the role that TCF proteins play in directing Wnt signals toward cell transformation and cancer progression. ..
- LEF/TCF Expression in Colon CancerMarian Waterman; Fiscal Year: 2007..To test this hypothesis, two strategies will be used to disrupt LEF/TCF function in colon cancer cells. Effects will be assessed by global gene expression profiles and cell growth and viability assays (Specific Aim 4). ..
- ACTIVITIES OF BETA CATENIN AND LEF/TCF COMPLEXESMarian Waterman; Fiscal Year: 2004..Aim 3 describes experiments to assess the role of LEF/TCF DNA binding domain in the recruitment of beta catenin and, paradoxically, an antagonizing nuclear co-activator to promoters. ..
- LEF/TCF Expression in Colon CancerMarian L Waterman; Fiscal Year: 2010..This project examines how two such collaborating pathways (Notch and Calmodulin Kinase II) modify Wnt signals in colon cancer and in newly established colon cancer stem cell lines. ..
