Consequences of Hoxb1 duplication in teleost fish

Consequences of hoxb1 duplication in teleost fish.

Vertebrate evolution is characterized by gene and genome duplication events. There is strong evidence that a whole-genome duplication occurred in the lineage leading to the teleost fishes. We have focused on the teleost hoxb1 duplicate genes as a paradigm to investigate the consequences of gene duplication. Previous analysis of the duplicated zebrafish hoxb1 genes suggested they have subfunctio...

Leptin in Teleost Fish

MicroRNA in Teleost Fish

MicroRNAs (miRNAs) are transcriptional and posttranscriptional regulators involved in nearly all known biological processes in distant eukaryotic clades. Their discovery and functional characterization have broadened our understanding of biological regulatory mechanisms in animals and plants. They show both evolutionary conserved and unique features across Metazoa. Here, we present the current ...

Expansion by whole genome duplication and evolution of the sox gene family in teleost fish

It is now recognized that several rounds of whole genome duplication (WGD) have occurred during the evolution of vertebrates, but the link between WGDs and phenotypic diversification remains unsolved. We have investigated in this study the impact of the teleost-specific WGD on the evolution of the sox gene family in teleostean fishes. The sox gene family, which encodes for transcription factors...
