Genetic Material

An inmate who spent two decades on death row before DNA evidence exonerated him walked out of prison a free man, saying he just wanted to get home and be with his family. Nicholas Yarris is the first Pennsylvania death row inmate cleared by DNA testing. Yarris' 1983 conviction for rape and murder was overturned last summer when DNA tests proved that genetic material found on the victim belonged to someone else.

Alnylam Pharmaceuticals Inc. and Isis Pharmaceuticals Inc. have formed a venture uniting Nobel Prize winners David Baltimore and Phillip Sharp to create drugs from a newly discovered class of genetic material. The venture, Regulus Therapeutics, will have exclusive licenses from Alnylam and Isis for technology focused on so-called microRNAs. The molecules regulate networks of genes that may be involved in diseases including cancer, viral infections and metabolic disorders, the companies said.

Scientists in Hawaii have cloned a trio of identical mice using ordinary cells rather than DNA extracted from the female reproductive system. This time, the cloned critters were male. The clones grew using genetic material extracted from tail cells of adult male mice, but only one grew to adulthood, according to a study in the June issue of the journal Nature Genetics.

Scientists have identified the cause of Werner syndrome, a rare accelerated aging disease whose sufferers prematurely develop gray hair, wrinkled skin, cataracts, cancer and heart disease, dying in their 40s. Researchers at the Salk Institute for Biological Studies in La Jolla reported in the journal Science that patients with Werner syndrome couldn't properly replicate the ends of their chromosomes due to a defective gene, WRN.

Come grilling season, expect your sirloin steak to come with a hearty side of sticker shock. Beef prices have reached all-time highs in the U.S. and aren't expected to come down any time soon. Extreme weather has thinned the nation's beef cattle herds to levels last seen in 1951, when there were about half as many mouths to feed in America. "We've seen strong prices before but nothing this extreme," said Dennis Smith, a commodities broker for Archer Financial Services in Chicago.

Scientists at Texas A&M University in College Station unveiled a disease-resistant black Angus bull, saying it could lead to safer beef and more efficient ranching worldwide. The month-old calf, called Bull 86 Squared, was cloned from genetic material frozen 15 years ago from Bull 86.

French researchers reported today that they had succeeded in cloning rabbits using genetic material from adult cells. The animal joins sheep, cattle, goats, mice, pigs and cats in the select but rapidly growing fraternity of cloned organisms. The four cloned female rabbits were born last year at the National Institute for Agronomical Research outside Paris.

British scientists have mapped chromosome 20, the third and longest chromosome to be sequenced in the Human Genome Project. Chromosome 20 is best known for harboring genes that contribute to forms of the brain-wasting Creutzfeldt-Jakob disease and severe-combined immunodeficiency, an illness in which the immune system is crippled. Chromosome 20 contains 727 genes and accounts for about 2% of the total human genetic material, the team reported in the Dec. 20 issue of Nature.

Small defects in the male chromosome may be responsible for some cases of infertility, University of Minnesota doctors report in the New England Journal of Medicine. Dr. Jon Pryor and his team found that 7% of the 200 infertile men they studied were missing tiny pieces of their Y chromosomes, genetic material found only in males. However, further study revealed that the deleted pieces did not always cause infertility.
