Statistical tests for differential expression in cDNA microarray experiments
Xiangqin Cui, Gary A Churchill Genome Biology 2003, 4:210 (17 March 2003)
Abstract | Full text | PDF
| PubMed | Cited on BioMed Central
|
Editor’s summary
The simplest statistical method for extracting biological information from microarray data is the t test. Analysis of variance (ANOVA) and the mixed ANOVA model are general and powerful approaches for more complex microarray experiments.

Abstract | Full text | PDF
| PubMed | Cited on BioMed Central
|
Editor’s summary
Three different protein prenyltransferases catalyze the attachment of prenyl lipid anchors to a variety of eukaryotic proteins. Farnesyltransferase-inhibitor drugs have been developed as anti-cancer agents and may also be able to treat several other diseases.

Modifications of histone cores and tails in V(D)J recombination
Kathrin Muegge Genome Biology 2003, 4:211 (31 March 2003)
Abstract | Full text | PDF
| PubMed
|
Editor’s summary
A recent study shows that methylated lysine 79 in the core region of histone H3 plays a role in regulating the rearrangement of V, D and J gene segments by providing a euchromatic 'mark' that may regulate access of the V(D)J recombinase.

The mouse genome sequence - the end of the tail, or just the beginning?
Janet Rossant, Stephen W Scherer Genome Biology 2003, 4:109 (1 April 2003)
Abstract | Full text | PDF
| PubMed
|
Editor’s summary
The recent flurry of papers on the mouse genome includes the description of the full genome assembly, analysis of the mouse transcriptome, the origin of interstrain variation, initial analysis of conserved non-coding regions and high-throughput expression analysis of a subset of genes. Each illustrates how the availability of the genome sequence will change the way mouse biologists do business in future.

Extreme conservation of non-repetitive non-coding regions near HoxD complex of vertebrates
Chilaka Sabarinadh, Subbaya Subramanian, Rakesh K Mishra Genome Biology 2003, 4:P2 (25 March 2003)
Abstract | Full text | PDF
|
Editor’s summary
An unprecedented conservation of non-coding DNA sequences adjacent to the HoxD complex of vertebrates is reported here. Stretches of hundreds of base pairs in a 7kb region upstream of HoxD complex show 100% conservation from fish to human, suggesting a critical function for these sequences in the regulation of the HoxD complex.

Haplotypic analysis of the TNF locus by association efficiency and entropy

Abstract | Full text | PDF

|
Editor’s summary
To understand the causal basis of TNF associations with disease, it is necessary to understand the haplotypic structure of this locus. The TNF locus in Gambian and Malawi human samples is haplotypically diverse and has a rich history of intragenic recombination. As a consequence, a large proportion of TNF single nucleotide polymorphisms (SNPs) must be typed to detect a disease-modifying SNP at this locus. The most informative subset of SNPs to genotype differs between the two populations.

As an entrée to characterizing plant parasitic nematode genomes, 5,700 expressed sequence tags (ESTs) from the infective second-stage larvae (L2) of the root-knot nematode Meloidogyne incognita have been analyzed. In addition to identifying putative nematode-specific and Tylenchida-specific genes, sequencing revealed previously uncharacterized horizontal gene transfer candidates in Meloidogyne with high identity to rhizobacterial genes.
