Discovery of the first resistance gene to rice yellow mottle virus

...to be the eIF(iso)4G translation initiation factor coded by the Rymv1 gene which is probably involved in viral protein translation, but also perhaps in other processes such as the virus's movement within the cell. The research team discovered mutations of the gene they analysed in three different resistant...

New gene found for Crohn's disease

...ne where the third SNP resided, they found that it coded for a protein that is part of the immune cell receptor for interleukin-23 (IL-23), an important mediator of inflammation in the body. However, when they began looking for all of the polymorphisms in the IL-23 receptor gene of affected individuals to ...

Scientists find major susceptibility gene for Crohn's disease

...ne where the third SNP resided, they found that it coded for a protein that is part of the immune cell receptor for interleukin-23 (IL-23), an important mediator of inflammation in the body. However, when they began looking for all of the polymorphisms in the IL-23 receptor gene of affected individuals to ...

Scientists lose instruments, gain first look at seafloor formation

...nts, however, only four out of 12 responded to the coded release signal and bobbed to the surface; three more responded to the signal, but did not come up. The rest remained silent. Tests of the water temperature and light-scattering near the sea floor revealed signs of a recent volcanic eruption. A seco...

Children's Hospital Oakland, Calif.'s new iron regulation discovery

...one or two proteins in the body. In this case the coded protein was Ferritin, which is essential for managing iron in the body. This discovery could help researchers design medications for patients with iron overload that occurs in hemochromotosis, Sickle Cell Disease and Thalassemia. "Currently, there...

New protein super-family discovered with critical functions for animal life

... cell culture and spinal cord neurons, the protein coded for by this gene stimulates lengthening and branching of neurons," Patterson says. Because many other DANGER proteins also are expressed in neurons, discovering their functions may be a key to deciphering the complexity of neuronal growth and develo...

Flu shot might also offer some protection against H5N1

...investigators first vaccinated mice using DNA that coded for N1 from a human influenza virus. This ensured that the mice would make only N1 and not one of the hemagglutinin proteins, thus eliminating any chance of confusion over whether their immune systems were vaccinated against hemagglutinin, neuraminid...

Drivers and passengers on the road to cancer

...team also found that the mutations carry important coded messages within them. The type of mutation found varies markedly between individual cancers, reflecting the processes that generated the mutations, some of which were active decades before the cancer showed itself. Patterns of mutations are an arc...

CSHL shows correcting RNA splicing may help treat spinal muscular atrophy

...oteins. Proteins are synthesized from instructions coded in the DNA through a multi-step process that includes RNA splicing. Information stored in the DNA of genes is transcribed into immature "pre-messenger RNAs" (pre-mRNAs), pre-mRNAs are then spliced into mature "messenger RNAs" (mRNAs), and finally, m...

3-D fusion: A better way to image heart disease

...art muscle," he noted. "The heart muscle was color coded to the blood flow brought in by the coronaries into the muscle. That blood flow information was obtained from a nuclear imaging scan," he further explained. Coronary artery disease (CAD), the most common form of heart disease, occurs when the arte...

Scientists ponder plant life on extrasolar Earthlike planets

...unlikely the same as our DNA that has information coded in a way that allows the ability to transfer information. Weve got proteins that do all of the dirty work in the cell in terms of chemistry. You can imagine a different sort of molecule that would do that sort of chemistry. Maybe it would have the...

New tumor markers -- 'Spot the differences'

..., we generated antibodies that detect the proteins coded by some of the messages. Using a microscope and colour-labelled antibodies, we managed to dye PC cells and to distinguish them from cells of a healthy pancreas or a pancreas with chronic pancreatitis (Fig. B). These results indicate the usefulness of...

Under magnetic force, nanoparticles may deliver gene therapy

... a circular molecule that here carried a gene that coded for a growth-inhibiting protein called adiponectin. By applying a magnetic field, the study team steered the particles into arterial smooth muscle cells. Inside each cell, the DNA separated from the particle, entered the cell nucleus, and produced en...

Genetic variation helps to understand predisposition to schizophrenia

...uence called a promoter, which enables genes to be coded for proteins. A protein called a transcription factor binds to the promoter and helps other proteins to express the gene. When the promoter is altered, the transcription factor may not bind properly and impair genetic expression. Law and colleagues s...
