Abstract
OVERVIEW
The goal of research in the Waterman laboratory is to understand how the Wnt signaling pathway regulates target genes through the actions of LEF/TCF transcription factors. Dysfunctional Wnt signals misregulate gene expression and cause cancer and most of our work on LEF/TCFs is within the context of the final step of this dysregulated pathway. LEF/TCF proteins bind to Wnt Response Elements in target genes and recruit ß-catenin for gene activation or repressors for gene silencing. There are two main areas of research: 1) Regulation of LEF/TCF expression, and 2) Structure and activities of LEF/TCFs. Our work in these two areas has led to new insights on LEF/TCF structure, Wnt response element recognition, signals from the tumor microenvironment and chromatin regulators that modify the types and amounts of LEF/TCFs. In almost every aspect LEF/TCF expression and/or function has been distorted in cancer.

REGULATION OF LEF/TCF TRANSCRIPTION AND TRANSLATION
Transcription: The LEF1 locus has two promoters for RNA polymerase II transcription, where each promoter produces a differently acting form of LEF-1. One promoter is activated in Wnt-linked cancers (P1), the other promoter is silenced (P2). We aim to identify the regulatory elements, transcription factors and signaling pathways that create this pattern, as the activated-silenced pattern produces only Wnt-promoting forms of LEF-1. We are also working to define common themes of transcription regulation of all four mammalian LEF/TCFs for a more comprehensive view of expression of this family is modulated during development and disease.
Translation: LEF1 mRNA produced from P1 contains two Internal Ribosome Entry Sites in its long 5’ UTR. We have discovered a cancer-relevant signaling pathway that regulates IRES activity and LEF-1 protein production. Current efforts are focused on a new method to isolate LEF1 mRNA/protein complexes for mass spectrometry analysis and IRES-factor discovery.

STRUCTURE AND ACTIVITIES OF LEF/TCFS
A new DNA binding domain: We have discovered a second DNA binding domain in the C-terminus of TCFs. Previously known as the CRARF region, we refer to it as the “C-clamp” because of four invariant and essential cysteines. The C-clamp is a new type of DNA binding domain and appears to be critical for TCF-mediated growth control. We aim to define the role of this domain in carcinogenesis and obtain structural and gene targeting information to develop ways to interfere with its function.
Nuclear export of TCFs: Another major effort in the laboratory is a focus on subcellular trafficking of LEF/TCFs. Our early research identified nuclear localization activities and receptors that ushered LEF/TCFs into the nucleus. More recently, we have discovered that certain mammalian TCFs engage in nuclear/cytoplasmic shuttling – an activity that is active and distorted in cancer. We have discovered a Wnt-linked kinase cascade that can control this shuttling, linking TCF trafficking to extracellular signals that may be aberrant in the tumor microenvironment. The Wnt-linked signal has elements of “canonical” and “non-canonical” signaling, and we are working to define these novel elements as well as the molecular changes in LEF/TCFs when export is triggered.
