Hox go omics: insights from Drosophilainto Hox gene targets (2007)

Pavlopoulos, Anastasios, Akam, Michael

Abstract Genetic studies of the targets of the Hox genes have revealed only the tip of the iceberg. Recent microarray studies that have identified hundreds more transcriptional responses to Hox genes...

Conservation of regulatory sequences and gene expression patterns in the disintegrating Drosophila Hox gene complex (2005)

Negre, Bárbara, Casillas, Sònia, Suzanne, Magali, Sánchez-Herrero, Ernesto, Akam, Michael, Nefedov, Michael, ...

Homeotic (Hox) genes are usually clustered and arranged in the same order as they are expressed along the anteroposterior body axis of metazoans. The mechanistic explanation for this colinearity has...

A Hox gene mutation that triggers nonsense-mediated RNA decay and affects alternative splicing during Drosophila development (2003)

Alonso, Claudio R., Akam, Michael

Nonsense mutations are usually assumed to affect protein function by generating truncated protein products. Nonetheless, it is now clear that these mutations affect not just protein synthesis but...

Oligonucleotide probes detect splicing variants in situ in Drosophila embryos (1992)

Artero, Rubén D., Akam, Michael, Pérez-Alonso, Manuel

We describe a method for the in situ detection of specific splicing variants. The method is based on the use of antisense oligonucleotides designed to span splice junctions labelled with digoxigenin...

Organization of the Hox gene cluster in the grasshopper, Schistocerca gregaria

Ferrier, David E. K., Akam, Michael

The conserved organization of the Hox genes throughout the animal kingdom has become one of the major paradigms of evolutionary developmental biology. We have examined the organization of the Hox...

Arthropods: Developmental diversity within a (super) phylum

Akam, Michael

The expression patterns of developmental genes provide new markers that address the homology of body parts and provide clues as to how body plans have evolved. Such markers support the idea that...

Hox gene control of segment-specific bristle patterns in Drosophila

Rozowski, Marion, Akam, Michael

Hox genes specify the different morphologies of segments along the anteroposterior axis of animals. How they control complex segment morphologies is not well understood. We have studied how the Hox...

The structure and expression of a hybrid homeotic gene

Rowe, Annie, Akam, Michael

We describe the structure and expression of an exceptional bithorax complex mutation, C1. This deletion mutation removes major portions of both the Ultrabithorax (Ubx) and abdominal-A (abd-A) protein...

Conserved sequence elements in the 5' region of the Ultrabithorax transcription unit

Wilde, C. Deborah, Akam, Michael

Clones homologous to the 5' region of the Ultrabithorax gene of Drosophila melanogaster have been isolated from D. pseudoobscura, D. funebris and Musca domestica. Regions that encode most of the Ubx...

Hox go omics: insights from Drosophila into Hox gene targets

Pavlopoulos, Anastasios, Akam, Michael

Microarray analysis reveals hundreds of hitherto unsuspected Hox gene targets.

Mitochondrial genomes suggest that hexapods and crustaceans are mutually paraphyletic

Cook, Charles E, Yue, Qiaoyun, Akam, Michael

For over a century the relationships between the four major groups of the phylum Arthropoda (Chelicerata, Crustacea, Hexapoda and Myriapoda) have been debated. Recent molecular evidence has confirmed...

The evolution of hexapod engrailed-family genes: evidence for conservation and concerted evolution

Peel, Andrew D, Telford, Maximilian J, Akam, Michael

Phylogenetic analyses imply that multiple engrailed-family gene duplications occurred during hexapod evolution, a view supported by previous reports of only a single engrailed-family gene in members...

Gene Circuit Analysis of the Terminal Gap Gene huckebein

Ashyraliyev, Maksat, Siggens, Ken, Janssens, Hilde, Blom, Joke, Akam, Michael, Jaeger, Johannes

The early embryo of Drosophila melanogaster provides a powerful model system to study the role of genes in pattern formation. The gap gene network constitutes the first zygotic regulatory tier in the...

Probing the evolution of appendage specialization by Hox gene misexpression in an emerging model crustacean

Pavlopoulos, Anastasios, Kontarakis, Zacharias, Liubicich, Danielle M., Serano, Julia M., Akam, Michael, Patel, Nipam H., ...

Changes in the expression of Hox genes have been widely linked to the evolution of animal body plans, but functional demonstrations of this relationship have been impeded by the lack of suitable...

Alternative Splicing Modulates Ubx Protein Function in Drosophila melanogaster

Reed, Hilary C., Hoare, Tim, Thomsen, Stefan, Weaver, Thomas A., White, Robert A. H., Akam, Michael, ...

The Drosophila Hox gene Ultrabithorax (Ubx) produces a family of protein isoforms through alternative splicing. Isoforms differ from one another by the presence of optional segments—encoded by...
