Scientists have shed new light on how the kidneys of the one-humped Arabian camel play an important role in helping it to cope with extremes.

Camelus dromedarius is the most important livestock animal in the arid and semi-arid regions of North and East Africa, the Arabian Peninsula and Iran, and continues to provide basic needs to millions of people. Thought to have been domesticated 3,000 to 6,000 years ago in the Arabian Peninsula, the camel has been used as a beast of burden, for riding and sport, and to produce milk, meat and shelter, and they are still used today for the same purposes.

This animal is so incredibly well adapted to the desert environment that can endure weeks without access to water. A very well-developed kidney is the key to produce highly concentrated urine and assure water is never wasted. In the current context of advancing desertification and climate change, there is renewed interest in the adaptations of camels. Further, advanced laboratory techniques allow to study the underlying genetic mechanisms of these adaptations.

However, there was not to date, a freely available and comprehensive study of the genes implicated in coping with dehydration in the kidney of the camel. The team analysed how thousands of genes changed in the camel kidney as a consequence of dehydration and rehydration and suggested that the amount of cholesterol in the kidney has a role in the water conservation process. They used different techniques to further validate these results
