DNA methylation is an important epigenetic mechanism that ensures correct gene expression and maintains genetic stability. DNA methyltransferase 1 (DNMT1) is the primary enzyme that maintains DNA methylation during replication. Dysregulation of DNMT1 is implicated in a variety of diseases. DNMT1 protein stability is regulated via various post-translational(More)
Obesity is a risk factor for many human diseases. However, the underlying molecular causes of obesity are not well understood. Here, we report that protein tyrosine phosphatase receptor T (PTPRT) knockout mice are resistant to high-fat diet-induced obesity. Those mice avoid many deleterious side effects of high-fat diet-induced obesity, displaying improved(More)
Cell differentiation in developing tissues is controlled by a small set of signaling pathways, which must coordinate the timing and levels of activation to ensure robust and precise outcomes. Highly coordinated activation of signaling pathways can result from cross-regulatory interactions in multi-pathway networks. Here we explore the dynamics and function(More)
It has long been thought that PTPs (protein tyrosine phosphatases) normally function as tumour suppressors. Recent high-throughput mutational analysis identified loss-of-function mutations in six PTPs in human colon cancers, providing critical cancer genetics evidence that PTPs can act as tumour suppressor genes. PTPRT (protein tyrosine phosphatase(More)
Protein tyrosine phosphatase receptor T (PTPRT) is frequently mutated in a variety of human cancers including colorectal cancer. Here we report that PTPRT knockout increases the size of mouse colon tumors in the Apcmin+/- genetic background, suggesting that inactivation of PTPRT promotes tumor progression. We previously demonstrated that PTPRT(More)
Forest tenures are a set of complicated institutions that have played a significant role in the forest sector's evolution in British Columbia. This paper analyzes the effect of forest tenure on land value. Various forms of tenure are briefly reviewed and a theoretical model of forest land value is developed. Data on forest tenure, forest cover, natural(More)
RNA interference (RNAi) is a eukaryotic gene-silencing system. Although the biochemistry of RNAi is relatively well defined, how this pathway is regulated remains incompletely understood. To identify genes involved in regulating the RNAi pathway, we screened for genetic mutations in Drosophila that alter the efficiency of RNAi. We identified the Drosophila(More)
