Nano-Probes Allow an Inside Look at Cell Nuclei

...rradiation. They have already visualized the dots' journey from the area surrounding the nucleus to inside the nucleus, a feat that opens the door for real-time observations of nuclear trafficking mechanisms. They also hope to target other cellular organelles besides the nucleus, such as mitochondria and Gol...

UCLA scientists transform HIV into cancer-seeking missile

... fireflies glow to the virus in order to track its journey from the bloodstream to new tumors in the animals' lungs. "For the past 20 years, gene therapy has been hampered by the lack of a good carrier for therapeutic genes that can travel through the blood and aim itself at a precise location, thereby mini...

Double triumph in stem cell quest

"This is an enormous stride in the long journey to determine whether nuclear-transfer-derived human embryonic stem cells might be eventually suitable for transplantation medicine," says Gerald Schatten of the University of Pittsburgh School of Medicine, the only non-Korean member of the team. But...

To sea or not to sea: When it comes to salmon sex, size sometimes doesn't matter

...eggs. And the tiny male has avoided the harrowing journey taken by most salmon to the ocean and back, bypassing hazards such as dams, sharks and fishermen. "In some species, all or a fraction of the individuals in some populations do not migrate to sea at all," he says. "These fish sacrifice the growing op...

Dr. Michael Fainzilber and graduate students Eran Perlson and Shlomit Hanz of the Weizmann Institute's Biological Chemistry Department found that the Erk messengers, together with their phosphorus message, ...

Searching the depths of the straits of Florida for disease cures

...ong trip that deters most. Divers who do make the journey are fond of Cay Sal because of its spectacular reefs, extensive cave systems, and abundant sea life, including the elusive whale shark. Harbor Branch scientists are attracted most to its steep topography between about 300 and 3,000 feet, which sugges...

Recombinant DNA technology may enable oral, rather than injectable, delivery of protein drugs

...new oral compound that is capable of surviving the journey through the gastrointestinal (GI) tract and then able to cross over into the bloodstream to be used by the body, according to research from the University of Southern California School of Pharmacy. This technology may allow for oral administration o...

Study shows how retinoic acid enters a cell's nucleus

...ucleus requires passage through water, a difficult journey for a hydrophobic compound. For RA to rapidly enter a cell's nucleus, it must catch a ride on a water-soluble protein called cellular retinoic acid-binding protein type II (CRABP-II). This protein was discovered over two decades ago, but until recent...
