Project description:C57BL/6 mice were subjected to sham surgery or orthotopic Hepa1-6 hepatic tumor inoculation. Spleen tissues from mice subjected to sham surgery (control mice), mice bearing a 2-week orthotopic hepatoma, and mice bearing a 4-week othotopic hepatoma were collected. Total RNA was extracted from the spleen tissues, and we used the RT² Profiler PCR array-mouse common cytokines (SABioscience) array panels to quantitate gene expression of cytokine genes from the spleens.
Project description:Genomic disorders are characterized by the presence of flanking segmental duplications that predispose these regions to recurrent rearrangement. Based on the duplication architecture of the genome we investigated 130 regions which we hypothesized as candidates for novel genomic disorders 1. We tested 290 patients with mental retardation by BAC array CGH, identifying sixteen pathogenic rearrangements, including four patients with de novo microdeletions of 17q21.31. Using oligonucleotide arrays we refined the breakpoints of this microdeletion, defining a 478 kb critical region containing six genes that were deleted in all four cases. The breakpoints of this deletion, and of four other pathogenic rearrangements in 1q21.1, 15q13, 15q24 and 17q12 were mapped to flanking segmental duplications, suggesting that these are also sites of recurrent rearrangement. In common with the 17q21.31 deletion, these breakpoint regions are also sites of copy number polymorphism in controls, indicating that these may be inherently unstable genomic regions.

Project description:To assess the role of 8-oxoguanine DNA glycosylase 1 (OGG1) on TNF induced pro-inflammatory gene expression. We used Qiagen Human Inflammatory Cytokines & Receptors PCR Array (PAHS-011Z) to quantitate inflammatory gene expression dependent on OGG1.
