And the segmentation clock keeps ticking

Article Abstract:

The segmentation clock is defined as the combination of various oscillating signals, which lead to the generation of somites at regular intervals from the presomitic mesoderm. The numerous researches conducted on the subject reveals that the segmentation clock is actually much more complex than it is thought to be and also includes oscillating expression of genes from three different signaling pathways in various coordinated networks.

The effect of GeneChip gene definitions on the microarray study of cancers

Article Abstract:

A large cancer dataset is used as an example to compare two major definitions and investigate their effects on classification, clustering, discovery of differentially expressed genes and gene-set-based analysis. The results have shown that the two definitions have agreed well on clustering and classification results but genes and gene sets discovered as differentially expressed or enriched can be very different.

Mining plant diversity: Gerbera as a model system for plant developmental and biosynthetic research

Article Abstract:

The scientific investigations into flower development and secondary metabolism in Gerbera are described. A cDNA microarray based on several expressed sequence tags (ESTs) is introduced as the newest tool for Gerbera research.
