Affymetrix Mouse Genome 430A 2.0 Array (mouse430a2)
Description
Expression of insulin in terminally differentiated non-beta pancreatic cell types could be important for treating type-1 diabetes. We observed that the kinase inhibitor GW8510 up-regulated insulin expression in mouse pancreatic alpha cells.
Publication Title
GW8510 increases insulin expression in pancreatic alpha cells through activation of p53 transcriptional activity.

Description
miRNA-mediated gene expression silencing has previously been shown to be important for a variety of physiological and pathological processes. Here, we have explored the role of one bona fide human-specific miRNA (miR-941) in evolution of the human-specific expression and function. Using combination of high-throughput sequencing (GSE26545), miRNA transfection and large-scale PCR of various human populations, we have shown that emergence and rapid expansion of miR-941 might take place on the human evolutionary linage between six and one million years ago. Functionally, miR-941 could be associated with hedgehog and insulin signaling pathways, and thus might potentially play a role in evolution of human longevity. Human-specific effects of miR-941 regulation are detectable in human brain and affect genes involved in neurotransmitter signaling. Furthermore, emergence of miR-941 on the human evolutionary linage was accompanied by the accelerated loss of its binding sites. Taken together, these results strongly implicate the contribution of miR-941 in evolution of the human-specific phenotype.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The mature CNS contains PDGFRA+ oligodendrocyte progenitor cells (OPC) which may remain quiescent, proliferate, or differentiate into oligodendrocytes. In human gliomas, rapidly proliferating Olig2+ cells resembling OPCs are frequently observed. We sought to identify, in vivo, candidate pathways uniquely required for OPC differentiation or quiescence. Using the bacTRAP methodology, we generated and analyzed mouse lines for translational profiling the major cells types (including OPCs), in the normal mouse brain. We then profiled oligodendoglial (Olig2+) cells from a mouse model of Pdgf-driven glioma. This analysis confirmed that Olig2+ tumor cells are most similar to OPCs, yet, it identified differences in key progenitor genes - candidates for promotion of differentiation or quiescence.
Publication Title
