Blood: Heat shock protein 90 regulates the expression of Wilms tumor 1 protein in myeloid leukemias

November 25, 2010

Hima Bansal 1, Sanjay Bansal, Manjeet Rao, Kevin P Foley, Jim Sang, David A Proia, Ronald K Blackman, Weiwen Ying, James Barsoum, Maria R Baer, Kevin Kelly, Ronan Swords, Gail E Tomlinson, Minoo Battiwalla, Francis J Giles, Kelvin P Lee, Swaminathan Padmanabhan Abstract The aberrant overexpression of Wilms tumor 1 (WT1) in myeloid leukemia plays an important role in blast cell survival and resistance to chemotherapy. High expression of WT1 is also […]

BMC Bioinformatics: Improving performance of mammalian microRNA target prediction

September 22, 2010

Hui Liu, Dong Yue, Yidong Chen, Shou-Jiang Gao & Yufei Huang Abstract Background MicroRNAs (miRNAs) are single-stranded non-coding RNAs known to regulate a wide range of cellular processes by silencing the gene expression at the protein and/or mRNA levels. Computational prediction of miRNA targets is essential for elucidating the detailed functions of miRNA. However, the prediction specificity and sensitivity of […]

Journal of Nucleic Acids: Mouse WRN Helicase Domain Is Not Required for Spontaneous Homologous Recombination-Mediated DNA Deletion

August 19, 2010

Adam D. Brown,1,2 Alison B. Claybon,1 and Alexander J. R. Bishop1,2 Abstract Werner syndrome is a rare disorder that manifests as premature aging and age-related diseases. WRN is the gene mutated in WS, and is one of five human RecQ helicase family members. WS cells exhibit genomic instability and altered proliferation, and in vitro studies suggest that WRN has a role in […]

Annals of Human Genetics: Power of Genetic Association Studies with Fixed and Random Genotype Frequencies

August 15, 2010

Julia Kozlitina Chao Xing Alexander Pertsemlidis William R. Schucany Summary When estimating the power of genetic association studies, the allele and genotype frequencies are often assumed to be known, and the numbers of individuals with each genotype are set equal to their expectations under Hardy‐Weinberg equilibrium. In fact, both allele and genotype frequencies are unknown […]

Nucleic Acids Research: PARP1 suppresses homologous recombination events in mice “in vivo”

July 21, 2010

Alison Claybon, Bijal Karia, Crystal Bruce, Alexander J. R. Bishop Abstract Recent studies suggest that PARP1 inhibitors, several of which are currently in a clinical trial, may selectively kill BRCA1/2 mutant cancer cells. It is thought that the success of this therapy is based on immitigable lethal DNA damage in the cancer cells resultant from the concurrent loss […]

Oncogene: MicroRNA-185 suppresses tumor growth and progression by targeting the Six1 oncogene in human cancers

July 5, 2010

J S Imam, K Buddavarapu, J S Lee-Chang, S Ganapathy, C Camosy, Y Chen & M K Rao Abstract Homeobox genes encode transcription factors that are essential for normal development and are often dysregulated in cancers. The molecular mechanisms that cause their misregulation in cancers are largely unknown. In this study, we investigate the mechanism by which the Six1 homeobox protein, which […]

BMC: MicroRNA expression distinguishes SCLC from NSCLC lung tumor cells and suggests a possible pathological relationship between SCLCs and NSCLCs

June 17, 2010

Liqin Du, Jeoffrey J Schageman, Irnov, Luc Girard, Scott M Hammond, John D Minna, Adi F Gazdar & Alexander Pertsemlidis Abstract Background Recent studies have shown that microRNAs (miRNAs) play roles in tumorigenesis and are reliable classifiers of certain cancer types and subtypes. However, the role of miRNAs in the pathogenesis and diagnosis of small cell […]

BMC Systems Biology: Building and analyzing protein interactome networks by cross-species comparisons

March 30, 2010

Amy M Wiles, Mark Doderer, Jianhua Ruan, Ting-Ting Gu, Dashnamoorthy Ravi, Barron Blackman & Alexander JR Bishop Abstract Background A genomic catalog of protein-protein interactions is a rich source of information, particularly for exploring the relationships between proteins. Numerous systems-wide and small-scale experiments have been conducted to identify interactions; however, our knowledge of all interactions for any one species is incomplete, and […]

Breast Cancer Research Treatment: Occult ovarian cancers identified at risk-reducing salpingo-oophorectomy in a prospective cohort of BRCA1/2 mutation carriers

February 24, 2010

Susan M Domchek 1, Tara M Friebel, Judy E Garber, Claudine Isaacs, Ellen Matloff, Rosalind Eeles, D Gareth Evans, Wendy Rubinstein, Christian F Singer, Stephen Rubin, Henry T Lynch, Mary B Daly, Jeffrey Weitzel, Patricia A Ganz, Gabriella Pichert, Olufunmilayo I Olopade, Gail Tomlinson, Nadine Tung, Joanne L Blum, Fergus Couch, Timothy R Rebbeck Abstract Risk-reducing salpingo-oophorectomy (RRSO) is widely used for cancer risk reduction in BRCA1 or BRCA2 (BRCA1/2) mutation carriers. Occult ovarian/fallopian tube cancers […]

Pediatric Blood & Cancer: Establishment and characterization of a cancer cell line derived from an aggressive childhood liver tumor

December 1, 2009

Tina T-L Chen 1, Dinesh Rakheja, Jaclyn Y Hung, Peter J Hornsby, Piotr Tabaczewski, Marcio Malogolowkin, James Feusner, Frank Miskevich, Roger Schultz, Gail E Tomlinson Abstract Background: Hepatoblastoma is a rare malignancy of childhood. The scarcity of adequate cell models has limited our understanding of this tumor. Here we describe and characterize a new human liver tumor cell line, Hep293TT, derived from an aggressive childhood hepatoblastoma. […]
