Progress toward an antitumor vaccine

... with a central protein chain and long side chains made of polysaccharides. The modified MUC1 would be a good target molecule (antigen) for antibodies in immunological antitumor therapy. The difficulty with this approach is that such sugar-containing compounds are completely ineffective at stimulating ...

Nurtured chimps rake it in

...l ‘hybrid’ rakes. Each rake head had a rigid side made of wood (functional) and another side made of flimsy cloth (non-functional). The reward was placed in front of the rigid side of one rake, and...

New findings challenge established views on human genome

...and disease. In recent years, researchers have made major strides in using DNA sequence data to identify genes, which are traditionally defined as the parts of the genome that code for proteins. The protein-coding component of these genes makes up just a small fraction of the human genome – 1.5 perce...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

...e organs receiving the bacteria with nanoparticles made the intended therapeutic proteins and emitted a light similar to a firefly's glow," Akin said. Certain bacteria are naturally programmed to dissolve vesicle membranes, a critical step to delivering the cargo. The nanoparticles are referred to as "...

Research finds that circadian rhythms dominate all life functions

...ch the genes function to an AC power grid, Ptitsyn made the discovery by plotting the expression of 20,000 genes on a scale of frequency, or intensity, over a two day period and sorting them by phase or timing of oscillation. Where previous studies have failed, the Colorado State study uses advanced algor...

UCF nanoparticle offers promise for treating glaucoma

A unique nanoparticle made in a laboratory at the University of Central Florida is proving promising as a drug delivery device for treating glaucoma, an eye disease that can cause blindness and affects millions of people worldwide. “The nanoparticle can safely get past the bl...

Researchers demonstrate way to control tree height

...lution, this innate immunity to one virus may have made us more vulnerable to HIV." Evidence of human immunity to this ancient retrovirus first emerged with the sequencing of the chimpanzee genome.
