Pioneering research to discover how a gene normally responsible for growth in unborn babies, ...

...is linked to certain cancers, is being carried out by a leading scientist in Cambridge.

Dr Adele Murrell has been awarded a grant from AICR (the Association for International Cancer Research) to study the strange behaviour of a gene called IGF2.

She explains: “We know that if this gene is over-active in the embryo, it results in overgrowth and can cause a rare but distressing syndrome that can lead to certain childhood cancers. Over-activity of the gene has also been reported in many adult cancers, including breast and bowel cancer.

“ Normally, we inherit two copies of our genes, one from our mother and the other from our father. Some of our genes, including IGF2, have the ability to remember their origin. We call this ‘imprinting.’ In the developing embryo, it is only the paternal IGF2 gene – the one from the father – that is active. However, it is the maternal IGF2 gene that can sometimes become active in adult cells and lead to the formation of a cancer.”

Scientists have discovered that imprinting is caused by subtle chemical changes to the structure of the DNA or the proteins associated with it. Now, with AICR support, Dr Murrell will investigate further proteins involved with the imprinting of the IFG2 gene to find out how this system is involved when this gene causes cancer.

Dr Mark Matfield, AICR’s scientific adviser believes the work may have significant implications for treating the disease in the future. “Imprinting is a way of turning specific genes on or off. Since problems with gene structure or activity are the fundamental cause of cancer, turning those ‘rogue’ genes off could be the basis of a new method of treatment.”

Derek Napier, AICR's Chief Executive says the grant awarded to Dr Murrell has been given in line with the charity's policy of funding the most exciting and novel approaches to research worldwide. " We believe it important to fund work that pushes the boundaries and Dr Murrell and her team are charged with tackling one of the greatest scientific challenges of all.”

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
