Chicken study sheds light on childhood eye disease
Scientists at the Roslin Institute studied chicken embryos to determine how fusion occurs.

New genes identified that are linked to ocular coloboma

A study of chicken embryos has identified new genes that could be responsible for the development of ocular coloboma in humans.

Ocular coloboma causes part of the eye to be missing at birth, severely affecting the patient’s vision. It accounts for up to 10 per cent of all childhood blindness and cannot be treated.

The disease is the result of errors in tissue fusion, which is essential for the formation of the eye and many other organs of the developing embryo.

Scientists at the Roslin Institute studied chicken embryos to determine how fusion occurs and identified genes that are switched on or off during the process.

One of the many newly identified genes included Netrin-1, which scientists say is likely to be critical in humans and other species, as well as in organs other than the eye.

Lead author Dr Joe Rainger said: “Identifying new genes and processes involved in tissue fusion will improve our understanding of how fusion defects occur, and whether these may be preventable.

"The fusion-genes we have revealed are also an excellent resource to support the identification of genetic defects in patient sequencing programmes.”

Endangered turtles rescued from smugglers

News Story 1
 A group of endangered turtles have found a new home at London Zoo after being rescued from smugglers.

The four big-headed turtles arrived at the zoo at the end of last year, after smugglers tried to illegally import them to Canada, labelled as toys.

One of the turtles, named Lady Triệu after a Vietnamese warrioress, has moved to a new exhibit in the zoo’s reptile house. She is the only one of her kind in a UK zoo.

Big-headed turtles have such large heads that they cannot pull them back into their shells. To compensate, they have armour plating from head to tail and a very sharp beak to fend off predators. They are ranked number 18 on ZSL’s EDGE of Existence reptile list, which puts threatened species at the forefront of conservation action. Image © ZSL
