Affymetrix probes containing runs of contiguous guanines are not gene-specific
High Density Oligonucleotide arrays (HDONAs), such as the Affymetrix HG-U133A GeneChip, use sets of probes chosen to match specified genes, with the expectation that if a particular gene is highly ...

Intra- and inter-individual genetic differences in gene expression
Genetic variation is known to influence the amount of mRNA produced by a gene. Given that the molecular machines control mRNA levels of multiple genes, we expect genetic variation in the components...

Systemic similarity analysis of compatibility drug-induced multiple pathway patterns in vivo
A major challenge in post-genomic research is to understand how physiological and pathological phenotypes arise from the networks of expressed genes and to develop powerful tools for translating th...

A novel class of endogenous shRNAs in human cells
Until now it is still not clear how many types and amounts of small RNAs (sRNAs) exist in humans. Here we report the identification of 1258 distinct sRNAs derived from intronic regions of protein-c...

ChIP-on-chip significance analysis reveals large-scale binding and regulation by human transcription factor oncogenes
ChIP-on-chip has emerged as a powerful tool to dissect the complex network of regulatory interactions between transcription factors and their targets. However, most ChIP-on-chip analysis methods us...

Diagnostic robustness of DNA microarrays in the classification of acute leukemia
Countless statistical methods have been described for the analysis of DNA microarrays, and each yields distinct results. This raises the question whether DNA microarrays are robust diagnostic tools...

DNA expression microarrays may be the wrong tool to identify biological pathways
DNA microarray expression signatures are expected to provide new insights into patho- physiological pathways. Numerous variant statistical methods have been described for each step of the signal an...
