Yale Scientists Find MicroRNA Regulates Ras Cancer Gene

Research in the laboratory of Assistant Professor Frank J. Slack at Yale University has identified a new way that a familiar gene is regulated in lung cancer, presenting new possibilities for diagnosis and treatment. The work is reported in March issues of the journals Cell and Developmental Cell. The oncogene Ras is out of control in about 20 percent of cancers where it is over-expressed...

Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

Huge colonies of seabirds accustomed to nesting on islands free of predators began disappearing when fur traders started introducing foxes onto islands in the Aleutian archipelago in the 18th century. The ground-nesting birds made easy meals for the foxes. A study published this week in the journal Science now shows that the effects of the introduced foxes rippled through entire island ecosystems...

Scientists reveal molecular secrets of the malaria parasite

In an innovative project with implicationsfor malaria vaccine development, scientists have used genomics,proteomics and gene expression studies to trace how malaria parasitesevolve on a molecular level as they move between their hosts and insectvectors.That focus on the parasites' complex life cycle is helping researchersunderstand when different genes switch on and off as the pathogensmet...

New RNA polymerase discovered in plants

Biologists at Washington University in St. Louis have discovered an entirely new cellular "machine" in plants that plays a significant role in plant flowering and DNA methylation, a key chemical process essential for an organism's development. A team headed by Craig Pikaard, Ph, D., Washington University professor of biology in Arts & Sciences, has discovered a fourth kind of RNA poly...

Glutathione-S-Transferase (GST) Colorimetric Assay Kit from Sigma-Aldrich

Description:Biochem/physiol Actions: Glutathione-S-transferases (GSTs) are a group of enzymes important in the detoxification of many xenobiotics in mammals. The enzymes protect cells against toxicants by conjugating the thiol group of the glutathione to electrophilic xenobiotics, and thereby defend cells against the mutagenic, carcinogenic, and toxic effects of the compounds. GST activity is presen...

Feeding channel created by malaria parasite - a new target for malaria treatments

Researchers have found pore-like holes in the membranes of red blood cells infected by the deadliest form of the malaria parasite. The parasite, Plasmodium falciparum, apparently uses these holes to supply itself with the nutrients it needs to grow and reproduce. The discovery may lead to the development of new treatments for malaria, a widespread and devastating disease. Mala...

Right drugs drastically cut stroke risk

In the biggest breakthrough, the incidence of the disease was found to have been cut to half by a combination of drugs that keeps blood pressure in check. The study involving about 6,000 patients over six years in many countries showed that strokes were cut by at least a quarter among patients given the drugs. // The drugs are inexpensive and easily available. Use of the drugs cut b...

Telomerase Vital In Maintaining Ability of Stem Cell to Multiply
