Description
Female mouse models of diabetic peripheral neuropathy (DPN) have not yet been identified. Our aim is firstly to demonstrate that female BTBR ob/ob mice display robust DPN and secondly, to perform relevant comparisons with non-diabetic and gender-matched controls. Lastly, microarray technology was employed to identify dysregulated genes and pathways in the SCN and DRG of female BTBR mice. Dorsal root ganglia (DRG) and sciatic nerve (SCN) were removed from female mice, RNA isolated and processed for gene expression profiling to identify differentially expressed genes using Affymetrix GeneChip Mouse Genome 430 2.0 Arrays.

Description
This work was designed to determine the role of the vascular endothelial growth factor A (VEGF) isoforms during early neuroepithelial development in the mammalian central nervous system (CNS), specifically in the forebrain. An emerging model of interdependence between neural and vascular systems includes VEGF, with its dual roles as a potent angiogenesis factor and neural regulator. Although a number of studies have implicated VEGF in CNS development, little is known about the role that the different VEGF isoforms play in early neurogenesis. We used a mouse model of disrupted VEGF isoform expression that eliminates the predominant brain isoform, VEGF164, and expresses only the diffusible form, VEGF120. We tested the hypothesis that VEGF164 plays a key role in controlling neural precursor populations in developing cortex. We used microarray analysis to compare gene expression differences between wild type and VEGF120 mice at E9.5, the primitive stem cell stage of the neuroepithelium. We quantified changes in PHH3-positive nuclei, neural stem cell markers (Pax6 and nestin) and the Tbr2-positive intermediate progenitors at E11.5 when the neural precursor population is expanding rapidly. Absence of VEGF164 (and VEGF188) leads to reduced proliferation without an apparent effect on the number of Tbr2-positive cells. There is a corresponding reduction in the number of mitotic spindles that are oriented parallel to the ventricular surface relative to those with a vertical or oblique angle. These results support a role for the VEGF isoforms in supporting the neural precursor population of the early neuroepithelium.

Description
The sequence of gene regulatory events that drive neonatal germ cell development in the mammalian testis is not yet clear. We assessed changes in mRNA utilization in the neonatal testis at 1 and 4 dpp, times when the testis contains quiescent gonocytes (1 dpp) and proliferating spermatogonia (4 dpp). There are not thought to be major changes in the nature or number of somatic cells over that interval.
