Cancer that colonizes our bodies

...organs in the body. But once it is there, like any newly stabilized species in different ecological niches, cancer is tough to get rid of. The former University of Alberta biologist has been working with DNA ?the molecule that carries our cells?genetic information ?ever since 1947, six years before its s...

Scientists unlock mystery of embryonic stem cell signaling pathway

A newly discovered small molecule called IQ-1 plays a key ...he studies of IQ-1 and its effects reported in the newly published PNAS paper were performed at the University of Washington in Seattle by Kahn and his colle...

Statin plus cancer drug deliver combo punch to brain cancer cells

Building on newly discovered genetic threads in the rich tapestry of biochemical signals that cause cancer, a Johns Hopkins Kimmel Cancer Center team has dramatically killed brain cancer cells by blocking those signals with a statin and an experimental antitumor drug....

New research may overturn conventional wisdom on drug-resistant tuberculosis

A newly released study suggests that the majority of cases of drug-resistant tuberculosis (TB) among patients undergoing treatment for the disease may be due to new infections, not acquired resistance. If confirmed in future studies the research, in the Marc...

Mosquito genes explain response to climate change

...rld, from the tropics to the polar regions. The newly created map contains 900 million DNA base pairs. There are three billion base pairs in humans. As various genome maps are being completed, scientists now face the task of determining how genes interact and how they produce specific phenotypes (observ...

Scientists discover new virus caused deaths of transplant recipients from single donor

...ransmission by organ transplantation, however, the newly discovered virus is sufficiently different that it could not be detected using existing screening methods. Over 30,000 organ transplants are performed in the U.S. each year. Knowledge of the genetic sequence of this virus will enable improvement...

Using dental X-rays to detect osteoporosis

...require extra time on the part of the dentist. The newly developed technique means that patients who are identified as being at risk can be referred for more thorough appropriate examinations....

Tiny clue reveals new path toward heart disease

...n smooth muscle. According to the researchers, the newly identified SNP may change the level of this protein in blood vessels, causing cells to congregate in one spot and form a plaque in the vessels to the heart. In addition to identifying the genetic variations in the kalirin gene, the researchers als...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

...archable list,?says Pandey. A report on all of the newly identified protein alterations is published in the Feb. 13 issue of the Proceedings of the National Academy of Sciences, while a report on the database appears in the March issue of Nature Biotechnology. Pandey’s team used electron transfer dissoc...

Gene hunters close in on Lou Gehrig’s disease

...ral sclerosis (ALS), Johns Hopkins scientists have newly identified 34 unique variations in the human genetic code among 276 unrelated subjects with ALS. The 34 so-called single nucleotide polymorphisms, or SNPs, represent good candidate genes predisposing people to the non-inherited form of the fatal neu...

Anti-herpes treatment reduces HIV levels in women infected with both viruses

.... In 2005, an estimated 4.1 million people were newly infected with HIV, mostly through heterosexual intercourse1. This alarming number of infections highlights the urgent need to intensify and expand proven prevention methods, and further, to identify and implement new methods of HIV prevention. A nu...

Killing the messenger RNA -- But which one?

Scientists discover new species of distinctive cloud-forest rodent

...wlands, may have arisen from Andean ancestors. The newly discovered species casts a striking new light on the evolution of an entire group of arboreal rodents." ...

Newly discovered fish named after New York aquarium biologist

...fish species are found nowhere else on earth. The newly described black and gold cichlid is about five inches long, and known locally as a "garaka." It occurs in several river system in the northeastern part of the country. Loiselle himself has discovered ?? fifteen freshwater fishes during his fourte...

How fish conquered the ocean

.... Finn, and adds, "This is especially so for their newly spawned eggs since they lack the adult organs and mechanisms responsible for coping with these problems. For years we studied various aspects of the physiological adaptations of the fish egg to the marine environment. It is most satisfying that Dr. F...

Brain tissue reveals possible genetic trigger for schizophrenia

... protein building blocks are made. MicroRNAs are a newly discovered class of mRNA that does not carry the code for a protein. Instead, these tiny strands of RNA act by binding to matching pieces of the protein coding mRNA, thus preventing the translation of mRNA to protein. When a cell needs certain prote...

When smell cells fail they call in stem cell reserves

... any, had grown back. They discovered that the newly grown cells, both nerve and non-nerve, grew from HBCs-a population of cells not previously known for repair abilities. “We were stunned because HBCs normally don’t grow much or do anything,?says Reed. “And the most surprising thing is that HBCs can g...

Cancer cells forming blood vessels send their copper to the edge

... sections of breast tumor tissue that were rich in newly formed blood vessels. "Once again," said Finney, "...ssels, in areas of tissue where blood vessels were newly invading surrounding tissue, the cells showed copper localized at the periphery of the cells and in ...

Widely used hepatitis B drug spurs HIV drug resistance

...tenth of what is used in humans, cut the number of newly infected cells in half. However, at increasing concentrations, the drug had no greater impact on suppressing HIV replication. HIV is a virus renowned for its ability to change form and thus evade or develop resistance to therapies designed to stop ...
