Proteome Science: Bayesian non-negative factor analysis for reconstructing transcription factor mediated regulatory networks

October 14, 2011

Jia Meng, Jianqiu (Michelle) Zhang, Yidong Chen & Yufei Huang Abstract Background Transcriptional regulation by a transcription factor (TF) controls the time and abundance of mRNA transcription. Due to the limitation of current proteomics technologies, large scale measurements of protein level activities of TFs is usually infeasible, making computational reconstruction of the transcriptional regulatory network a difficult task. Results […]

BMC Research Notes: A model-based circular binary segmentation algorithm for the analysis of array CGH data

October 10, 2011

Fang-Han Hsu, Hung-I H Chen, Mong-Hsun Tsai, Liang-Chuan Lai, Chi-Cheng Huang, Shih-Hsin Tu, Eric Y Chuang & Yidong Chen Abstract Background Circular Binary Segmentation (CBS) is a permutation-based algorithm for array Comparative Genomic Hybridization (aCGH) data analysis. CBS accurately segments data by detecting change-points using a maximal-t test, but an extensive computational burden is involved for evaluating the significance of change-points using permutations.

The presence of family […]

Carcinogenesis: Candidate gene association analysis of acute lymphoblastic leukemia identifies new susceptibility locus at 11p15 (LMO1)

September 21, 2011

Joke Beuten 1, Jonathan A L Gelfond, Duangjai Piwkham, Brad H Pollock, Naomi J Winick, Anderson B Collier 3rd, Gail E Tomlinson Abstract To determine the contribution of susceptibility loci in explaining the genetic basis of acute lymphoblastic leukemia (ALL), we genotyped 29 high-potential candidate genes with 672 tagged single-nucleotide polymorphisms (SNPs) in a sample (163 cases and 251 healthy controls) of […]

Molecular & Cellular Biology: A Conditional Mouse Model for Measuring the Frequency of Homologous Recombination Events In Vivo in the Absence of Essential Genes

August 10, 2011

Adam D. Brown, Alison B. Claybon, Alexander J. R. Bishop ABSTRACT The ability to detect and repair DNA damage is crucial to the prevention of various diseases. The loss of function of genes involved in these processes is known to result in significant developmental defects and/or predisposition to cancer. One such DNA repair mechanism, homologous recombination, has […]

Objective: To quantify how often throughout adulthood clinically […]

Cancer Epidemiology Biomarkers & Prevention: Polymorphisms in CYP1A1 and ethnic-specific susceptibility to acute lymphoblastic leukemia in children.

July 1, 2011

Ryan M Swinney 1, Joke Beuten, Anderson B Collier 3rd, Tina T-L Chen, Naomi J Winick, Brad H Pollock, Gail E Tomlinson Abstract Background: Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. The U.S. Surveillance Epidemiology and End Results (SEER) registry reports that Hispanic children have the highest incidence of ALL, however, it is unclear if this is due to genetic […]

Pediatric Developmental Pathology: Activated NOTCH2 is overexpressed in hepatoblastomas: an immunohistochemical study

June 3, 2011

Jason B Litten 1, Tina T-L Chen, Roger Schultz, Karl Herman, Jessica Comstock, Joshua Schiffman, Gail E Tomlinson, Dinesh Rakheja Abstract Hepatoblastoma is a pediatric malignancy characterized by the uncontrolled proliferation of immature hepatocytes (hepatoblasts). This disease is diagnosed primarily in children younger than 5 years and is disproportionately observed in former premature infants. Cytogenetically, hepatoblastoma is characterized by numerical aberrations, as well […]
