New anti-inflammatory strategy for cancer therapy identified by UCSD researchers
...uired for the activation of NF-kB, which acts as a master
switch to turn on inflammation in response to bacterial or viral infections. In turn, NF-kB sets off a chain of reactions that lead to cancer. Mice used in the new study were given colon or breast tumor cells which metastasized to the lung. ...

watchmaker, he is looking for a set of universal laws that describe the rhythms of plant and animal life. The principles that he and his colleagues are discovering appear to reveal deep biological truths about everything from the way cells consume nu...
Single isolated mouse skin cell can generate into variety of epidermal tissues
...rchers didn't know if hair and skin arose from one master
cell -- a "multipotent" stem cell that can morph into a number of tissue types -- or from two populations of "unipotent" stem cells that are destined to be a single tissue. "There has been increasing evidence that there are cells within this compart...
Advances in tumor angiogenesis Dendritic cells co-opted to the dark side

switch for tumor angiogenesis, with a dose-dependent effect: in this case, dendritic cells were converted into endothelial-like cells only in the presence of high VEGF-A levels. "The levels of VEGF-A generated in our animal model of ovarian cancer re...
Genetically-engineered 'marathon mouse' keeps on running

regulator of numerous genes -- to enhance that protein's activity. According to Evans, they had not expected the profound and far-reaching physiological effects of this single genetic alteration. "In previous work, we had shown that in various tissu...

Embryonic stem cell therapy shows steady benefits in rebuilding infarcted heart
...m cells, Mayo Clinic researchers transformed these master
cell types into fully functional cardiac cells and transplanted them into damaged regions of the myocardium, where the cells integrated into the infarct and showed rapid and robust improvements, which were stable over an extended period post-therapy....
UCSD researchers are first to demonstrate molecular link between inflammation and cancer
...led nuclear factor kappa B (NF-kB), that acts as a master
switch to turn on inflammation in response to bacterial or viral infections. In epithelial cells, NF-kB promotes the development of cancer not through inflammation, but through inhibition of a cell-killing process called apoptosis. In myeloid cells...
Casanova or caveman: Scientists isolate nerve cells that choreograph male fly's courtship behavior
...s had previously discovered that fruitless was the master
gene that controlled sexual behavior in male flies. "We found that the fruitless gene was responsible for building the neuronal circuitry for male courtship," Baker said. "This circuit, which is built into the fly's brain and ventral nerve cord, is c...
