DNA Molecules Used To Assemble Nanoparticles

... steps, Baker said. Baker foresees a nanoparticle cluster in which a single dendrimer carries three single-strands of DNA, each with a sequence specific to the DNA attached to other kinds of dendrimers. Put into solution with these other tinker toys, the molecule would self-assemble into a four-dendrimer co...

Scientists document complex genomic events leading to the birth of new genes

...2. Comprised of eight family members, the RGP gene cluster may help to explain what sets apart humans and other primates from the rest of the animal kingdom. Human chromosome 2 has always intrigued primate biologists; it formed from the fusion of two mid-sized ape chromosomes and is the only cytogenetic di...

Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

...ifferent," says Gourley. "Mitochondria conspire to cluster around the nucleus and work together to supply energy to the healthy, functioning cell. In contrast, the mitochondria in the cancer cell sit all over, isolated and balled up in a quiescent, non-functioning state. Apparently, the rapidly growing cance...

They also identified gene clusters that were active in stable asthma, but not the acute form of the disease. "Now that we know what genes are turned on during ...

The circadian clock: Understanding nature's timepiece

A cluster of brain cells less than half the size of a pencil eraser tells you when to wake up, when to be hungry and when it's time to go to sleep. The same cells also cause you to be disoriented after you've flown across multiple time zones. The human circad...

Chemical Engineer Kao Explores Antibiotic Synthesis With DNA Chips

...al strains. The answer, it seems, lies not in the cluster of genes known to produce the antibiotic, but in a mutation of another gene that co-regulates the timing of expression for the antibiotic-producing genes. The result? The mutant produces erythromycin for five days. The nonmutant produces it for only ...

Chronic Sinus Infection Thought To Be Tissue Issue, Mayo Clinic Scientists Show It's Snot

While major basic protein was not distributed in the nasal and sinus tissue, the level of this protein in the mucus of chronic sinus inf...

"The way these integrins rearrange and cluster on the cell surface can send a signal back into the cell that modifies the cell's behavior, allowing it to do things like secrete inflammatory factors," Pham explains.

Mosaic mouse technique offers a powerful new tool to study diseases and genetics

...ppens when a specific gene is removed from a small cluster of cells in a living animal. With MADM, cells carrying an altered gene of interest actually turn green for easier observation. "We use a green fluorescent protein," Luo says. "So now if you mutate a gene, you'll know in which cell the normal gene is...

Bioinformatics reveals new gene regulation system

To strengthen the prediction that these proteins were the transcription factors that bind the NrdR-box, the team used another comparative genom...
