Mitosis gets harder thanks to new gene discovery

07.04.2008
A biological process taught to every pupil studying GCSE science has just become a little more complicated thanks to a new discovery published today.

Scientists from the University of Bath have found that a protein called RASSF7 is essential for mitosis, the process by which a cell divides in two.

In research published in the journal Molecular Biology of the Cell, the scientists have shown that the protein is essential for building the microtubules that allow the two halves of the cell to slide apart.

“What makes mitosis so interesting is that it is one of the biological processes that everyone remembers from their days at school,” said Dr Andrew Chalmers from the University’s Department of Biology & Biochemistry.

“As well as being one of Nature’s most important processes, our interest in mitosis stems from the fact that if you want to kill cancer cells, then stopping them from dividing is a useful way of doing this.

“Several cancer treatments block cell division by targeting microtubules, Taxol is a well known example. It is even possible that RASSF7 might be a future drug target”.

During the different phases of mitosis the pairs of chromosomes within the cell condense and attach to microtubule fibres that pull the sister chromatids to opposite sides of the cell.

The cell then divides in cytokinesis, to produce two identical daughter cells.

RASSF7 is the latest of a battery of proteins involved in managing the complex process of mitosis.

“During mitosis, the chromosomes containing the DNA are pulled apart in two halves by an array of microtubules centred on the centrosomes,” said Dr Chalmers.

“Without the RASSF7 protein, the microtubules do not develop properly and cell division is halted.

“This is the first functional study of this protein, and we hope to extend our knowledge of how it works in the future.”

The research was funded by the Medical Research Council.

The work was carried out in Dr Chalmers laboratory by Dr Victoria Sherwood and two final year undergraduate project students from the University, Ria Manbodh and Carol Sheppard.

Dr Sherwood will now continue her research on cancer at a new job at the Lund University Clinical Research Centre, Sweden.

The University of Bath is one of the UK's leading universities, with an international reputation for quality research and teaching. In 15 subject areas the University of Bath is rated in the top ten in the country.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
