A synthetic drug that controls blood sugar in obese mice demonstrates the potential of a DNA-dependent method for developing new chemical compounds.

After decades of searching, researchers may have finally identified a chemical compound that could be used to study and treat diabetes.

Researchers have long known that the body carries an enzyme that breaks down insulin inside cells and helps regulate the bodys response to sugarsa process that goes awry in type 2 diabetes. Genetic studies have shown that people with type 2 diabetes are more likely to have mutations in the gene that encodes a protein called insulin-degrading enzyme, or IDE. But exactly which processes the enzyme controls is not yet clear.

David Liu and his team at Harvard have identified a chemical compound that can inhibit IDE, and they have shown that the compound increases the amount of insulin in the bloodstreams of both normal mice and ones made obese by an unhealthy diet.

Liu and his team developed the new compound using a novel method called DNA-templated synthesis. This involves linking thousands of different chemical structures to thousands of unique DNA strands, and then taking advantage of the interactions between two strands of DNA to bring the chemical building blocks together to create new ones.

Patients with type 2 diabetes either have an insufficient amount of insulin in their blood or do not properly respond to the hormone in order to move the bodys main energy sourceglucoseinto cells. Researchers have speculated for decades that a drug that could inhibit IDE might help some type 2 diabetes patients.

Small-molecule drugs, which make up the majority of medicines, are compounds far smaller than less common biological medicines like antibodies. They are developed using libraries of thousands or millions of known chemical substances. Each compound is screened to see if it has a desired effect on a biological target, such as an enzyme or other protein known to be involved in a disease. Pharmaceutical companies may use robotics to test many chemical reactions in parallel.

DNA-templated synthesis allows researchers without a lot of expensive equipment to more quickly evaluate all the potential small molecule interactions that could occur from a library of building blocks. A single student with only minimal equipment and infrastructure can evaluate millions of potential small molecule-protein interactions in one to two weeks, says Liu.

Furthermore, DNA-templated synthesis can produce structures that are often not found in chemical libraries used by many pharmaceutical companies, which may be why the Harvard team was able to identify an IDE-controlling drug when so many had failed in the past.

The newly identified IDE inhibitor could be the starting point for developing a powerful new drug for type 2 diabetes. Another compound was previously known to inhibit IDE, but it had unwanted side effects, and it survived for only a few minutes in the body. The new inhibitor lasts for hours, says Liu.

KUALA LUMPUR: Dua sampel coklat Cadbury iaitu Coklat Susu dengan Kacang Hazel (Cadbury Dairy Milk Hazelnut) dan Coklat Susu dengan Buah Badam (Cadbury Dairy Milk Roast Almond) dikesan mengandungi DNA babi (porcine).

DNA khinzir itu dikesan Kementerian Kesihatan dalam sampel Coklat Susu dengan Kacang Hazel bernombor kelompok (batch no) NO200813M01H I2 bertarikh luput 13 November 2014 dan Coklat Susu dengan Buah Badam dengan nombor kelompok 221013N01R I1 bertarikh luput 15 Januari 2015.

Ketika memaklumkan perkara itu dalam kenyataan semalam, Ketua Pengarah Kesihatan Datuk Dr Noor Hisham Abdullah berkata analisis terhadap Cadbury Dairy Milk Chocolate bagaimanapun tidak menemui kandungan DNA tersebut.

Isu pengesanan DNA babi dalam produk Cadbury tersebar luas di media sosial sejak semalam yang memaparkan keputusan analisis terhadap dua produk berkenaan.

Dr Noor Hisham berkata ketiga-tiga sampel coklat itu telah diambil untuk analisis DNA babi bagi tujuan pemantauan.

Beliau berkata pengeluar coklat terbabit, Cadbury Confectionery Malaysia Sdn Bhd akan memanggil balik produk-produk itu daripada pasaran dengan serta-merta.

Kementerian Kesihatan menasihati orang ramai supaya membaca nombor kelompok pada label produk sebelum membeli atau memakannya, kata Dr Noor Hisham.

Pengguna boleh mengemukakan sebarang soalan kepada Kementerian Kesihatan melalui laman web Bahagian Keselamatan dan Kualiti Makanan di http://fsq.moh.gov.my atau http://www.facebook.com/bkkmhq. Bernama

Bird DNA linked: The closest relative of New Zealand's iconic kiwi is a 10-foot-tall elephant bird that was native to Madagascar, a new DNA study reveals.

They might be the odd couple of the bird world.

Scientists on Thursday identified the closest relative of New Zealand's famed kiwi, a shy chicken-sized flightless bird, as the elephant bird of Madagascar, a flightless giant that was 10 feet (3 meters) tall and went extinct a few centuries ago.

The surprising findings, based on DNA extracted from the bones of two elephant bird species, force a re-evaluation of the ancestry of the group of flightless birds called ratites that reside in the world's southern continents, they added.

The group, which boasts some of the world's largest birds, includes emus and cassowaries in Australia, rheas in South America, ostriches in Africa and kiwis in New Zealand. Ratites that have disappeared in recent centuries include the moa of New Zealand and the elephant bird.

The researchers compared elephant bird DNA to the other birds and saw a close genetic link to the kiwi despite obvious differences in size, body shape and lifestyle - and the fact they lived about 7,000 miles (11,500 km) apart.

The largest elephant bird species weighed more than 600 pounds (275 kg). Kiwis reach around 11 pounds (5 kg).

There has been a lively debate among bird experts about the origins of the ratites and how they came to live where they do.
