Project description:Genomic instability, including microsatellite instability (MSI) and gross chromosomal abnormalities, has been described in sporadic colorectal cancer (CRC) and MSI has been suggested to have prognostic significance. However, there are few prognostically relevant biomarkers. Here we explore the potential of the analysis of DNA copy number changes at 1Mb resolution to predict survivorship in sporadic CRC.

Project description:This study aimed to evaluate the clinical value of copy number variations (CNVs) in fetuses with ultrasonic soft markers. Among 1131 fetuses, 729 had single ultrasonic soft marker, 322 had two ultrasonic soft markers, and 80 had three or more ultrasonic soft markers. All fetuses underwent single nucleotide polymorphism (SNP) array analysis. Among 1131 fetuses with ultrasonic soft markers, 46 had chromosomal abnormalities. In addition to the 46 fetuses with chromosomal abnormalities consistent with the results of the karyotyping analysis, the SNP array identified additional 6.1% (69/1131) abnormal CNVs. No significant difference was found in the rate of abnormal CNVs among the groups. The SNP array can fully complement conventional karyotyping in fetuses with ultrasonic soft markers, improve detection rate of chromosomal abnormalities, and affect pregnancy outcomes.

Project description:Chromosomal instability is one of the hallmarks of tumors, which can result in the gain or loss of specific genomic regions or even entire chromosomes. These copy number aberrations (CNAs) play an important role in carcinogenesis and malignant progression through CNA-induced gene expression alterations and, subsequently, key cancer-specific processes. In the current study, we applied aCGH analysis to screen out CNAs with potential prognostic value in lung SCC patients.

Project description:Purpose Chromosomal aberrations are a hallmark of multiple myeloma but their global prognostic impact is largely unknown. Methods We performed a genome-wide analysis of malignant plasma cells from 192 newly myeloma patients using high-density, single-nucleotide polymorphism (SNP) arrays to identify genetic lesions associated with prognosis. Results Our analyses revealed deletions and amplifications in 98% of cases. Amplifications in 1q and deletions in 1p, 12p, 14q, 16q, and 22q were the most frequent lesions associated with adverse prognosis while recurrent amplifications of chromosomes 5, 9, 11, 15 and 19 conferred a favorable prognosis. Multivariate analysis retained three independent lesions: amp(1q23.3), amp(5q31.3) and del(12p13.31). When adjusted to the established prognostic variables ie t(4;14), and serum beta2-microglobulin (Sb2M), del(12p13.31) remained the most powerful independent marker (P <.0001; hazard ratio = 3.17) followed by Sb2M (P <.0001; hazard ratio = 2.78) and amp(5q31.3) (P =.0005; hazard ratio = 0.37). Cases with amp(5q31.3) alone and low Sb2M had an excellent prognosis (5-year overall survival = 87%) conversely cases with del(12p13.31) alone or amp(5q31.3) and del(12p13.31) and high Sb2M had a very poor outcome (5-year overall survival = 20%). Moreover, integration of SNP mapping and gene expression identified CD27 as potential critical gene responsible for poor prognosis of del(12p) myeloma patients. Conclusion These findings demonstrate the power and accessibility of molecular karyotyping to identify novel strong independent prognostic markers: amp(5q31.3) and del(12p13.31) and to provide insights into putative pathways deregulated in sub classes of cancer patients.

Project description:Chromosomal abnormalities are important causes of miscarriages. To delinate the chromosomal abnormalities in miscarriages, 564 miscarriages were collected and analyzed using single nucleotide polymorphism (SNP) array. 336 (59.6%) miscarriages were with abnormal copy number variations (CNVs), including 325 (57.6%) miscarriages with pathogenic CNVs and 11 (2%) miscarriages with variations of unknown significance (VOUS). The remaining 228 (40.4%) miscarriages had no clinically relevant chromosomal variants.

Project description:Genomic abnormalities that are associated with mesecnhmal phenotype of GBM were detected in glioblastoma cell lines. Experiment Overall Design: Whole genomic DNA of GBM cell lines (W-98, D431, F-502, and S-496) and the fibroblast cell line were evaluated for allelic imbalances and chromosomal copy number abnormalities by using a highdensity single-nucleotide polymorphic (SNP) array analysis (Affymetrix XbaI 131 Array).
