Differential gene expression mechanisms ensure cellular differentiation and plasticity to
shape ontogenetic and phylogenetic diversity of cell types. A key regulator of differential …

Transcription factors are key cellular components that control gene expression: their
activities determine how cells function and respond to the environment. Currently, there is …

Sturgeons seem to be frozen in time. The archaic characteristics of this ancient fish lineage
place it in a key phylogenetic position at the base of the~ 30,000 modern teleost fish …

In eukaryotes transcriptional regulation often involves multiple long-range elements and is
influenced by the genomic environment. A prime example of this concerns the mouse X …

Zebrafish, a popular organism for studying embryonic development and for modeling human
diseases, has so far lacked a systematic functional annotation program akin to those in other …

Long-range regulatory interactions play an important role in sha** gene-expression
programs. However, the genomic features that organize these activities are still poorly …

INTRODUCTION In animals, gene regulatory networks specify cell identity in space and
time. Transcription of genes in these networks is modulated by a class of cis-regulatory …

Promoters are crucial for gene regulation. They vary greatly in terms of associated regulatory
elements, sequence motifs, the choice of transcription start sites and other features. Several …

James A. Shapiro proposes an important new paradigm for understanding biological
evolution, the core organizing principle of biology. Shapiro introduces crucial new molecular …

The relationship between chromatin organization and gene regulation remains unclear.
While disruption of chromatin domains and domain boundaries can lead to misexpression of …
