Glioblastomas (GBMs) are deadly tumors of the central nervous system. Most GBM exhibit homozygous deletions of the CDKN2A and CDKN2B tumor suppressors at 9p21.3, although loss of CDKN2A/B alone is insufficient to drive gliomagenesis. MIR31HG, which encodes microRNA-31 (miR-31), is a novel non-coding tumor suppressor positioned adjacent to CDKN2A/B at 9p21.3. We have determined that miR-31 expre...
BACKGROUND Methylation of genes regulating cell-cycle check-point (INK4 cyclin-dependent kinase inhibitors), apoptosis (XAF1), adhesion (CDH13), JUNB and Wnt signalling (soluble Wnt inhibitors) has been implicated in pathogenesis of haematological and epithelial cancers. METHOD The authors studied the methylation status of CDKN2A, CDKN2B, XAF1, CDH13, JUNB and a panel of soluble Wnt inhibitor...
Identifying genetic variants with pleiotropic associations can uncover common pathways influencing multiple cancers. We took a two-stage approach to conduct genome-wide association studies for lung, ovary, breast, prostate, and colorectal cancer from the GAME-ON/GECCO Network (61,851 cases, 61,820 controls) to identify pleiotropic loci. Findings were replicated in independent association studie...
For the determination of methylation levels in genomic regulatory DNA sequences a high-sensitive assay for detecting 5'methyl-cytosines (5'mC) in non-bisulfite-treated DNA has been established. The system is designed for the application of immunofluorescence using a monoclonal antibody that specifically recognizes 5'mC in single-stranded DNA hybridized to oligonucleotide microarrays. For assay ...
Type 2 diabetes in humans and in obese mice is polygenic. In recent genome-wide association studies, genetic markers explaining a small portion of the genetic contribution to the disease were discovered. However, functional evidence linking these genes with the pathogenesis of diabetes is scarce. We performed RNA sequencing-based transcriptomics of islets from two obese mouse strains, a diabete...
BACKGROUND The myelodysplastic syndromes (MDS) are a group of stem cell disorders characterized by dysplasia of one or more hematopoietic cell lineages and a risk of progression to acute myeloid leukemia. The cytidine analog azacitidine (Vidaza), a hypomethylating agent, improves survival in patients with MDS, but its mechanism of action is not well understood. MATERIALS AND METHODS The effec...
Several designs and analytical approaches have been proposed to dissect offspring from maternal genetic contributions to early-onset diseases. However, lack of parental controls halts the direct verification of the assumption of mating symmetry (MS) required to assess maternally-mediated effects. In this study, we used simulations to investigate the performance of existing methods under mating ...
