Green alga closes wounds by means of enzymatic activation of a cross-linking protein

A small wound is painful, but is normally not a problem. Like all multicellular organisms, our bodies form new tissue around the damaged cells. Single-celled organisms cannot do this. In order to survive an injury, they have to quickly repair the cell itself. Large single-celled organisms, such as the green alga Caulerpa taxifolia, which can be several meters long, are especially at risk for injuries.

Genes TEL2 and MYC cooperate with each other to promote pediatric cases of the immune system cancer B-cell lymphoma

The genes TEL2 and MYC cooperate with each other to promote pediatric cases of the immune system cancer B-cell lymphoma. This finding, from investigators at St. Jude Children's Research Hospital, is published in the current issue of Molecular Cell Biology (MCB).

Why respiratory viral infections are often more severe in people with asthma

Lung cells from asthma sufferers fail to invoke critical anti-viral defenses when infected with the common cold virus, according to a study in the March 21 issue of The Journal of Experimental Medicine. These results could help explain why respiratory viral infections are often more severe in people with asthma and how infection can trigger asthma attacks.

Scientists provide insight into the molecular mechanisms behind Listeria monocytogenes

When the bacterium Listeria monocytogenes invades the body, it commandeers its host cell's actin cytoskeleton to invade other cells. In a report published in the Journal of Biological Chemistry, a group of scientists provide insight into the molecular mechanisms behind this infection technique.

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.

Chemists say they have identified a gene that appears to play a key role in the development of type 1 diabetes

In the current study, the researchers focused on the formation of the MIF protein (macrophage migration inhibitory factor), a proinflammatory protein that they showed in previous studies is elevated in diabetic animals and may be involved in the cascade of immunological events that leads to the destruction of the pancreas and the subsequent onset of type 1 diabetes.

RNA loops and knots guide genetic modifications

University of Connecticut Health Center scientist, Robert Reenan, has uncovered new rules of RNA recoding - a genetic editing method cells use to expand the number of proteins assembled from a single DNA code.

Study reveals how brain's immune system fights viral encephalitis

The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages - by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain.

Drug combo gives lung cancer patients longer life

Preliminary results from a large randomized clinical trial, sponsored by the National Cancer Institute (NCI), by a network of researchers led by the Eastern Cooperative Oncology Group. Genentech, Inc., have shown that patients with previously untreated advanced non-squamous non-small cell lung cancer who received bevacizumab (Avastin) in combination with standard chemotherapy lived longer than patients who received the same chemotherapy without bevacizumab.

Beneficial effects of Alpha-Linolenic acid in walnuts

The recently-announced USDA dietary guidelines stress the need for consumers to be more aware of the benefits of polyunsaturated essential omega-3 fatty acids in order to achieve a healthy diet. Many people look to fish, such as salmon, for omega-3s, but plant sources such as walnuts are also specifically noted in the USDA recommendations.
