The recent wave of publications describing genome-wide association (GWA) studies of coronary artery disease (CAD) is beginning to wane. These GWA studies have identified a host of genetic variants that are associated with CAD. As expected, within a span of a few months this initial flood of GWA studies has inspired a matching surge of replication studies. At this juncture it is perhaps pertinen...
Malignant cells from 52 children with acute lymphocytic leukemia (ALL) were investigated for inactivation of the p15ink4B and p16ink4 genes and other genetic alterations on chromosome 9p21. Homozygous deletions of the p15ink4B and/or the p16ink4 genes were detected in 16 cases and a further 9 cases showed evidence of allelic loss either by hemizygous deletion or loss of heterozygosity (LOH) for...
BACKGROUND Cholangiocarcinoma is a frequent complication of primary sclerosing cholangitis and is a leading cause of mortality in patients with this disease. The tumor suppressor gene p16 is commonly inactivated in many neoplasms; however, the role of p16 in the pathogenesis of cholangiocarcinoma is unclear. Therefore, we examined the role of p16 inactivation in the pathogenesis of cholangiocar...
BACKGROUND One of the most robust genetic associations for cardiovascular disease (CVD) is the Chromosome 9p21 region. However, the interaction of this locus with environmental factors has not been extensively explored. We investigated the association of 9p21 with myocardial infarction (MI) in individuals of different ethnicities, and tested for an interaction with environmental factors. METH...
BACKGROUND AND OBJECTIVES Disruption of either the p14ARF- mdm2- p53 or p16INK4A- Rb1 pathways produces a breakdown of regulatory mechanisms and creates a gateway for tumorigenesis. Since the incidence and clinical implications of abnormalities of TP53, CDKN2A (encoding for p16 and p14) and MDM2 genes (chromosome 12) in multiple myeloma (MM) is not clear, we investigated allelic loss at the for...
Low-grade follicle center lymphoma (LGFCL) is characterized genetically by the t(14;18) translocation and an indolent clinical course. Histologic progression from LGFCL to an aggressive diffuse large B-cell lymphoma (DLCL) occurs in 60% to 80% of cases, and this transformation is associated with the accumulation of secondary genetic alterations. Using 10 polymorphic microsatellite markers spann...
The loss of DNA sequences on chromosomal bands 9p21-22 has been documented in a variety of malignancies including leukemias, gliomas, lung cancers, and melanomas. Because of the high incidence of monosomy 9 detected by both cytogenetics and loss of heterozygosity studies in bladder cancer, we examined seven bladder cancer cell lines for deletions in this region. Using seven DNA probes that span...
BACKGROUND Vascular aneurysm is an abnormal local dilatation of an artery that can lead to vessel rupture and sudden death. The only treatment involves surgical or endovascular repair or exclusion. There is currently no approved medical therapy for this condition. Recent data established a strong association between genetic variants in the 9p21 chromosomal region in humans and the presence of c...
