- Drosophila Gene 1.0 ST Array (drogene10st)
Description
PFJ (4 ml for a final concentration of 19,000 mg gallic acid equivalent (GAE) per kg diet or 0.86 mg GAE per kcal diet) was supplemented to larvae of fruit flies (Drosophila melanogaster) given a semi-purified diet to observe for possible effects on energy metabolism and lifespan. Larvae were used five days since the egg stage for gene expression studies. Results from the microarray data analysis carried out show that fruit fly larvae given PFJ had up-regulated transport and metabolic processes, while development and morphogenesis processes were down-regulated.

PFJ (4 ml for a final concentration of 19,000 mg gallic acid equivalent (GAE) per kg diet or 0.86 mg GAE per kcal diet) was supplemented to larvae of fruit flies (Drosophila melanogaster) given a semi-purified diet to observe for possible effects on energy metabolism and lifespan. Fat bodies extracted from these larvae were used five days since the egg stage for gene expression studies. Results from the microarray data analysis carried out show that fruit fly larva fat bodies given PFJ had up-regulated heat shock protein genes, while cell cycle and growth genes were down-regulated.

Description
Adipocytes arise from commitment and differentiation of adipose precursors in white adipose tissue (WAT). In studying adipogenesis, precursor markers, including Pref-1 and PDGFRa, are used to isolate precursors from stromal vascular fraction of WAT, but the relationship among the markers is not known. Here, we used Pref-1 promoter-rtTA system in mice for labeling Pref-1+ cells and for inducible inactivation of Pref-1 target, Sox9. We show requirement of Sox9 for maintenance of Pref-1+ proliferative, early precursors. Upon Sox9 inactivation, these Pref-1+ cells become PDGFRa+ cells that express early adipogenic markers. Thus, we show for the first time that Pref-1+ cells precede PDGFRa+ cells in the adipogenic pathway and that Sox9 inactivation is required for WAT growth and expansion. Furthermore, we show that, in maintaining early adipose precursors, Sox9 activates Meis1 which prevents adipogenic differentiation. Our study also demonstrates the Pref-1 promoter-rtTA system for inducible gene inactivation in early adipose precursor population. Overall design: RNA-Sequencing for differentially expressed genes (more than 2-fold) between GFP+ (Pref-1+) ingWAT SVF cells from floxed and Sox9 PreASKO mice (n=6 pooled).

Description
The ability to generate defined null mutations in mice revolutionized the analysis of gene function in mammals. However, gene-deficient mice generated by using 129-derived embryonic stem (ES) cells may carry large segments of 129 DNA, even when extensively backcrossed to reference strains, such as C57BL/6J, and this may confound interpretation of experiments performed in these mice. Tissue plasminogen activator (tPA), encoded by the PLAT gene, is a fibrinolytic serine protease that is widely expressed in the brain. A large number of neurological abnormalities have been reported in tPA-deficient mice. The studies here compare genes differentially expressed in the brains of Plat-/- mice from two independent Plat-/- mouse derivations to wild-type C57BL/6J mice. One strain denoted “Old” was constructed in ES cells from a 129 mouse and backcrossed extensively to C57BL/6J, and one denoted “New” Plat-/- mouse was constructed using zinc finger nucleases directly in the C57BL/6J-Plat-/- mouse strain. We identify a significant set of genes that are differentially expressed in the brains of Old Plat-/- mice that preferentially cluster in the vicinity of Plat on chromosome 8, apparently linked to more than 20 Mbp of DNA flanking Plat being of 129 origin. No such clustering is seen in the New Plat-/- mice. Overall design: Whole-transcriptome profiling of the cerebral cortex of wild-type control C57BL/6J mice and two independent Plat-/- mice strains on the C57BL/6J background.
