Post-doc Publication: CRISPR/Cas9 method in zebrafish
Aug. 14, 2013—A simple and robust method for targeted mutagenesis in zebrafish has long been sought. Previous methods generate monoallelic mutations in the germ line of F0 animals, usually delaying homozygosity for the mutation to the F2 generation. Generation of robust biallelic mutations in the F0 would allow for phenotypic analysis directly in injected animals. Recently the...

Loss of the par3 polarity protein promotes breast tumorigenesis and metastasis.
Nov. 23, 2012—McCaffrey LM, Montalbano J, Mihai C, Macara IG. Rosalind and Morris Goodman Cancer Research Centre, Department of Oncology, McGill University, Montreal H3A 1A3, Canada. Electronic address: luke.mccaffrey@mcgill.ca. Abstract Loss of epithelial organization is a hallmark of carcinomas, but whether polarity regulates tumor growth and metastasis is poorly understood. To address this issue, we depleted the...
Cytokinetic regulation of cell polarity
Nov. 23, 2012—The rod-shaped fission yeast Schizosaccharomyces pombe, which undergoes cycles of monopolar-to-bipolar tip growth, is an attractive organism for studying cell-cycle regulation of polarity establishment. While previous research has described factors mediating this process from interphase cell tips, we found that division site signaling also impacts the re-establishment of bipolar cell growth in the ensuing cell...

Identification of XIAP as a critical regulator of Wnt signaling
Mar. 21, 2012—beta-catenin accumulates in the nucleus and binds to the transcription factor, TCF/Lef, to activate Wnt target gene transcription. In order for beta-catenin to bind TCF/Lef, however, the transcriptional corepressor Groucho (Gro)/TLE, which is bound to TCF/Lef, must be displaced. Work by Hanson et al. shows that X-linked Inhibitor of Apoptosis (XIAP), an E3 ubiquitin ligase,...
