Further, our work and that of others has suggested functions of these moleculesin vivo. Eric received his MS in biomedicine from Uppsala University, Sweden in 2010. Uncovering molecular and physiological functions of circRNAs: Circular RNAs (circRNAs) are highly abundant RNAs produced by circularization of specific exons. Proximity labeling-based methods coupled with mass spectrometry (MS) offer a high-throughput approach for systematic analysis of spatially-restricted proteomes. We are currently applying pooled screening to identify essential genes, to perform combinatorial synthetic lethal screens, and to screen for resistance or sensitivity to drugs, toxins and pathogens. We have also generated stable nuclease-dead Cas9 activator (dCas9a) cell lines that can be used, after transfection with gRNAs, to perform overexpression screens - thus complementing loss of function screens.

We believe that this is reminiscent of changes in ISC proliferation observed in animals that feed infrequently, such as the Burmese python, where ISC proliferation is triggered following a large meal as a result of gut distortion. A slow RNA polymerase II affects alternative splicing in vivo. Mouse-olfactory bulb, brain stem, and thalamus-Mock. In response to tissue damage reagents such as paraquat and bleomycin, TrpA1 mediates calcium influx, which in turn activates Ras/MAPK pathway and induces stem cell proliferation.
