Source of molecular triggers in cutaneous T cell lymphoma identified

... physiologic laboratory system mimicking the tight relationship in vivo between CTCL cells and LC. The research team considered three broad categories of antigen as the source of the signal: the protein products of tumor viruses, of mutated genes, and of normal but usually inactive genes. The study reports that ...

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

... voracious predator of bacteria and shares a close relationship in the human gut with its bacterial neighbors. Because the parasite uses the same methods to kill bacteria as it uses to damage human cells and cause disease, the level of certain bacteria in the colon can be an important determinant of the amoeba's ...

Plants respond similarly to signals from friends, enemies

...e some of the plant's energy to survive. A similar relationship appeared when Weerasinghe studied the signals between plants and nematodes, even though the nematode provides no benefit to its host. Root-knot nematodes form feeding cells ?so-called giant cells ?in the plant and later galls or knots on it. "We don...

Sea skate experiment sheds light on human cell transport

...dy's defenses against cancer. "There is a possible relationship between operation of these channels and the uncontrolled multiplication of cancer cells," Goldstein said. "If so, this research points up an important area for future research." ...

Yale Scientists Find MicroRNA Regulates Ras Cancer Gene

...or, Slack's team used bioinformatics and found the relationship to Ras. Let-7 in humans is identical to the sequence in the worm, and both binding site and pathway for Ras are highly conserved. Tissue from lung cancer tumors, compared with their normal adjacent tissue, had reduced let-7 and increased Ras -- the ...

A bacterial genome reveals new targets to combat infectious disease

...hat live within their cells, but in this case, the relationship is classic mutualism, with each benefiting from th...uman host. Thus, understanding the details of this relationship may help identify new strategies for controlling diseases caused by filarial nematodes. In a new stu...

Gene variations explain drug dose required to control seizures

...y and is the drug target for phenytoin. Given its relationship to both anti-epileptic drugs tested, the SCN1A variant may be of particular importance for understanding patient response to drug treatment, said the researchers, noting that many other anti-epilepsy drugs act on related brain proteins. "The range o...

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

...nship. That means that at a certain moment in this relationship some kind of 'tipping point' occurs, so that a relatively small increase in clathrin kicks endocytosis into high gear." The study was conducted in fibroblasts, a kind of cell used in many cell-culture experiments. But Dr. Ryan said the findings have...

Researchers find missing genes of ancient organism

... operate gives clues to -- but not proof of -- the relationship between modern and ancient organisms. ### Other authors on the paper include Lennart Randau and Michael J. Hohn from Yale, and Richard Münch and Dieter Jahn from the Technical University Braunschweig, Germany. This work was supported by grants from...

New research indicates a 'troubled' greenhouse is brewing

...g the late Paleocene epoch. Retallack explored the relationship between seasonality and rainfall in soils, then applied the same techniques to buried soils spanning the ancient greenhouse event. "This is known to have been a time of high atmospheric carbon dioxide from studies of the breathing pores in fossil le...

Bird Brains Show How Trial and Error May Contribute to Learning

...Brainard said. Next, the researchers analyzed the relationship between song and the natural neural activity of LMAN during the two types of male finch song, the performance-quality song directed at females, accompanied by some posturing and feather plumping, and the experimental solo variations, called "undirect...

"The combination of our GeneChip platform and the ArrayAssist software makes the industry-leading methods for measuring gene expression on a genomic-scale available to...

VCU Researchers Identify Networks Of Genes Responding To Alcohol In The Brain

... genes with changes in expression had a functional relationship with each other. For example, they determined that many genes regulated by alcohol participated in certain biological pathways, such as the one leading to the production of myelin. Myelin is a form of molecular insulation that allows nerve cells to s...

Sequencing of marine bacterium will help study of cell communication

...ar biology. Other researchers are focusing on the relationship between the bacterium and its animal host. The PNAS article concludes, "If we are to understand the unifying themes underlying these contrasting bacteria–host interactions, we must begin to use comparative genomic approaches with closely related path...
