Project description:Sudden unexplained death in childhood (SUDC) is death of a child over one year of age that is unexplained after review of clinical history, circumstances of death, and complete autopsy with ancillary testing. Multiple etiologies may cause SUDC, with parallels to sudden unexpected death in epilepsy (SUDEP) in SUDC with a history of febrile seizures, suggesting possible abnormalities in hippocampus and cortex. To identify molecular signaling pathways underlying SUDC, we performed label-free quantitative mass spectrometry on microdissected frontal cortex, hippocampal dentate gyrus (DG), and cornu ammonis (CA1-3) in SUDC (n=19) and pediatric control cases (n=19) with an explained cause of death.
Project description:Purpose: Congenital heart disease (CHD) is the most common type of birth defect and the main noninfectious cause of death during the neonatal stage. Currently, hemizygous loss-of-function variants in NONO(The non-POU domain containing, octamer-binding) gene have been described as the cause of congenital heart defects in males. However, the effects of NONO on cardiac development have not been fully elucidated.
Project description:Septic shock is the most common cause of death in intensive care units. The aim of this study is to investigate the role of circular RNA (circRNA) and mRNA expression profiles and functional networks in aortic tissue of septic shock.
Project description:Lung cancer is the worldwide leading cause of death from cancer. This GEO series correspond to one of the BAC aCGH data sets used as validation cohort for the study: Landscape of somatic allelic imbalances and copy number alterations in human lung cancer, Int J Cancer 2013.
Project description:SP110b is an interferon (IFN)-induced nuclear protein and may function as a transcriptional co-activator/repressor. IFNγ activates monocytes/macrophages thereby mediating inflammation. However, uncontrolled activation induces monocyte/macrophage cell death, which may cause immunopathology. We have demonstrated that SP110b expression prevented IFNγ-mediated monocyte/macrophage cell death. To explore the molecular mechanisms by which SP110b suppresses IFNγ-induced cell death, we performed a genome-wide microarray analysis to identify genetic determinants associated with IFNγ-induced cell death and regulated by SP110b.
Project description:The pediatric tumor neuroblastoma is the second cause of cancer-related death in children. Although several recurrent gene aberrations have been found, the main signaling networks in the neuroblastoma cell, that can give important clues for more specific, more efficient treatment, is still unknown. Here we demonstrate an analysis of the MEIS1 pathway in neuroblastic tumors. It suggests important regulatory connections to tumor differentiation, cell cycle, and cell death. Time-course experiment of MEIS1-shRNA induction, with 5 timepoints.
Project description:Hepatocellular carcinoma (HCC) is currently the third leading cause of death worldwide and the most common type of primary liver cancer, finding noninvasive biomarkers for HCC diagnostic and prognostic are very urging. Previous genomic studies mainly focus on finding miRNA biomarkers for HCC. In this study, we focus on finding circRNA fragments suitable for serving as hcc biomarkers with plasma exosomal RNA-seq..
Project description:Ovarian cancer is the seventh-most common cancer and the eight-most common cause of death from cancer in woman. Some women with ovarian cancer survive a long time (> 10yrs). We want to know if there’s a genetic difference between these long survivors and the broader population of interest. Affymetrix SNP arrays were performed according to the manufacturer's directions on sample DNA.
