Genomic analysis of regulatory network dynamics reveals large topological changes

Article Abstract:

A study of the dynamics of a biological network on a genomic scale, by integrating transcriptional regulatory information and gene-expression data for multiple conditions in Saccharomyces cerevisiae is presented. It is concluded that many of the concepts reported in the study particularly, the large-scale topological changes and hub transience- would apply to other biological networks, including complex sub-systems in higher eukaryotes.

Fashionable cells

Article Abstract:

Most of the cells that make up the human body are supported by a cytoskeleton, an internal network of protein filaments. The similarities in the properties of a cell's network of structural filaments are explored.

Self-help for insulin cells

Article Abstract:

The origin of beta-cells in adult mice is examined. Insulin-producing beta-cells seems to have risen abundantly from beta-cells themselves, offering a new outlook on regenerative medicine.
