Genetic Information

August 16, 2003 | From Staff and Wire Reports
Martha Chase, 75, a researcher who in her early 20s became part of one of the most famous DNA experiments ever conducted, the so-called "blender experiment," died Aug. 8 of pneumonia at a hospital in Lorain, Ohio, according to her guardian and lawyer, Brent English of Cleveland. Chase had been suffering from dementia for many years. Chase and biologist Alfred D. Hershey, working at Cold Spring Harbor Laboratory in Long Island, N.Y.

Japanese researchers have demonstrated that a human virus called HTLV-1 can cause rheumatoid arthritis in mice. Experts said the discovery provides strong proof that viruses can cause arthritis. HTLV-1 is a so-called retrovirus, closely related to the AIDS virus, that is capable of inserting its own genetic information into the genes of its host during an infection. It causes leukemia and at least two rare degenerative nerve disorders.

Scientists at the City of Hope National Medical Center in Duarte said Monday that they have developed a new test for the AIDS virus that could reduce the risk of tainted blood transfusions and help scientists study the effectiveness of experimental drugs. Current tests detect antibodies to the virus, which can take months to develop. But John J. Rossi, a molecular geneticist at the City of Hope, said the new test would allow detection of the virus just a few days after exposure.

Deputies assigned to the security floor at the courthouse said that spectator seats have been assigned this way: News media: 25 Victims' families: 18 Public: 10 Defense and prosecution: 7 Simpson's family: 5 DNA Tests DNA test results will not play a part in the preliminary hearing of O. J. Simpson. Some preliminary results have been returned, but the final results are not expected for weeks. Sources have said the preliminary results point to Simpson.

A team led by Dr. Barry Forman of the City of Hope Diabetes Center in Duarte has identified what they call the first steroid-like hormone to be discovered in 30 years. They report in today's Nature that the hormone, called androstanol, appears to have a mechanism of action different from that of most other steroids. Most steroid hormones stimulate the transcription of genes, the process in which genetic information contained in DNA is converted into proteins.

Biologists have taken a small step closer to reproducing the origins of life by creating self-replicating RNA, the substance used by cells to transmit genetic information from DNA to cellular machinery. Many scientists now think that the first life was composed entirely of RNA. Self-replicating RNA would thus have many properties of the first "living" organism.

Alfred D. Hershey, a chemist who won the Nobel Prize for showing that DNA is the carrier of genetic information, has died. He was 88. Hershey, a staff member at the Cold Spring Harbor Laboratory in New York since 1950, died Thursday in New York. He shared the 1969 Nobel Prize in medicine with physicist-biologist Max Delbruck and biologist Salvador Luria. The three were known collectively as "the phage group."
President Bush on Saturday equated discrimination based on genetic information with race, age and gender bias, and said he would support legislation to make it illegal. The nearly complete mapping of the human genetic code has given rise to concerns that information about a person's genetic makeup could be used to deny jobs or health insurance or to raise insurance premiums. "Genetic discrimination is unfair to workers and their families," Bush said in his weekly radio address.

Gene-hunting pioneer Incyte Corp. announced Monday that it would lay off more than half its staff and close a gene-collection office, completing its transition out of the once red-hot field of genomics. The company said its proprietary database of human genes could no longer compete now that detailed genetic codes are available free via the Internet.
