Technology for image-based screening to enhance protein production

New medicines being developed to treat complex diseases, such as cancer, multiple sclerosis, and rheumatoid arthritis are increasingly becoming large and complex molecules, such as proteins. These molecules must be produced using cells grown in a laboratory or production facility. A key bottleneck in the development of such new medicines is producing sufficient quantities of these molecules for various stages of rigorous testing to ensure safety and efficacy. This project will develop a technology to generate better producer cells in order to increase their productivity.

New strategies for unclogging microcirculatory obstructions in the healthy and diabetic brain

Recent work from our laboratory has shown that the brain capillaries routinely get 'stuck,' clogged by cells and debris even under healthy conditions. Most of these clogged capillaries clear within seconds to minutes, however, some can remain stuck for much longer. We also reported that about one third of these clogged capillaries were eliminated from the blood vessel network and never get replaced. Importantly, there are certain conditions which can increase the risk of clogged blood vessels in the brain such as diabetes.

Orthogonal multicolour high-affinity tags for RNA imaging and manipulation

RNA plays a very important role in the regulation of gene expression. Yet, the spatial and temporal dynamics of RNA are still poorly understood, mainly due to the scarcity of effective and simple RNA imaging and purification techniques.

The development of technologies that simultaneously allow imaging, purification and manipulation of multiple RNAs in live cells promises to enable the study of RNA in development, metabolism and disease, which is essential for understanding the control of gene expression in diseases such as autism, cancers and type II diabetes.

Genomic Organization At Large (GOALS) predicts aggressive biological behaviour in prostate and breast cancers

Prostate cancer is the most commonly diagnosed form of cancer for men in North America. Prostate cancer deaths have been in decline since the mid-1990s after the discovery of Prostate-Specific Antigen (PSA), which, when used for screening, results in a steep increase in the number of early diagnoses. A large percent of these PSA-detected cases do not express clinically, are slow growing, and do not require treatment, and therefore do not contribute significantly to overall mortality. Conversely, some slow growing cancers are very aggressive and result in death.

Insight into motor cortex function from in vivo imaging of individual neurons

The cortex is a thin layer on the surface of the brain where most information processing takes place. The cortex is separated into several layers. There are large numbers of neural interconnections that exist between the different cortical layers, as well as many connections with neurons of the spinal cord. In the somatosensory cortex, where the perception of touch is analyzed, there is a spatial representation of the body on its surface.
