Optimized LOWESS normalization parameter selection for DNA microarray dataJohn A Berger
Department of Electrical and Computer Engineering, University of California, Santa Barbara, CA 93106 9560, USA
BMC Bioinformatics 5:194. 2004..Parameters are usually chosen arbitrarily, which may reduce the efficiency of the normalization and result in non-optimally normalized data. Thus, there is a need to explore LOWESS parameter selection in greater detail...
Therapeutic targets for HIV-1 infection in the host proteomeWinnie S Liang
Neurogenomics Division, Translational Genomics Research Institute, Phoenix, AZ 85004, USA
Retrovirology 2:20. 2005..Therefore, to identify cellular proteins that may be up-regulated in HIV infection and play a role in infection, we analyzed the effects of Tat on cellular gene expression during various phases of the cell cycle...
Modeling of signal-response cascades using decision tree analysisSampsa Hautaniemi
Biological Engineering Division, Massachusetts Institute of Technology, Cambridge, 02139, USA
Bioinformatics 21:2027-35. 2005..we conclude that decision tree methodology may facilitate elucidation of signal-response cascade relationships and generate experimentally testable predictions, which can be used as directions for future experiments...
Multiple reaction monitoring for robust quantitative proteomic analysis of cellular signaling networksAlejandro Wolf-Yadlin
Biological Engineering Division, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Proc Natl Acad Sci U S A 104:5860-5. 2007..Using this approach, it should now be possible to routinely monitor the phosphorylation status of hundreds of nodes across multiple biological conditions...
Effects of HER2 overexpression on cell signaling networks governing proliferation and migrationAlejandro Wolf-Yadlin
Biological Engineering Division, MIT, Cambridge, MA, USA
Mol Syst Biol 2:54. 2006..Combining these modeling approaches enabled association of epidermal growth factor receptor family dimerization to activation of specific phosphorylation sites, which appear to most critically regulate proliferation and/or migration...
Integrated mechanistic and data-driven modelling for multivariate analysis of signalling pathwaysFei Hua
Biological Engineering Division, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
J R Soc Interface 3:515-26. 2006..In conclusion, our framework provides a novel approach to understand the multivariate dependencies among molecules in complex networks, and can potentially be used to identify combinatorial targets for therapeutic interventions...
Transcriptional profiling reflects shared and unique characters for CD34+ and CD133+ cellsHeidi Hemmoranta
Research and Development, Finnish Red Cross Blood Service, Helsinki, Finland
Stem Cells Dev 15:839-51. 2006..These profiles suggest that CD34(+) and CD133(+) cells may have different roles in hematopoietic regeneration...
A novel strategy for microarray quality control using Bayesian networksSampsa Hautaniemi
Institute of Signal Processing, Tampere University of Technology, PO Box 553, 33101 Tampere, Finland
Bioinformatics 19:2031-8. 2003..A typical microarray experiment consists of tens of thousands of spots on a microarray, making manual extraction of poor quality spots impossible. Thus, there is a need for a reliable and general microarray spot quality control strategy...
Global gene expression profile of human cord blood-derived CD133+ cellsTaina Jaatinen
Finnish Red Cross Blood Service, Kivihaantie 7, 00310 Helsinki, Finland
Stem Cells 24:631-41. 2006..This study provides a gene expression profile for human CD133+ cells. It presents a set of genes that may be used to unravel the properties of the CD133+ cell population, assumed to be highly enriched in HSCs...
Decision tree modeling predicts effects of inhibiting contractility signaling on cell motilitySourabh Kharait
Department of Pathology, University of Pittsburgh, Pittsburgh, PA 15213, USA
BMC Syst Biol 1:9. 2007....
