UCSD study clarifies insulin's role in blocking release of energy in patients with type II diabetes

...own off, because the body continues to produce and store more triglyceride instead of breaking down the fat as released energy. “Somehow, insulin knows how to specifically block catecholamine-induced PKA, but not other molecules,?said Christopher Hupfeld, assistant professor of Medicine in the UCSD Divisi...

Molecular miners find pain relief drugs from the sea

...earch. "With a single cone snail we can create and store large libraries of conotoxin genes." It was using this genetic mining technique that ACV1 was discovered ?its peptide sequence was predicted solely from the DNA sequence. The peptide was then chemically synthesised in large quantities suitable for b...

Mechanism for the captation of nutrients in plants- unknown to date

... "swallow up" nutrients in order to metabolise and store them. These "swallowed-up" substances are incorporated into micro-vesicles that end up pouring their contents into an internal compartment of a vegetable cell known as the vacuola. Once inside the vacuola, the substances or nutrients are broken up, s...

Stanford gut check shows diversity of intestinal ecosystem

...tic close neighbors in the existing databases that store sequence information about all known species. "We thought we would find new ones, but it was a bit surprising to see such a large percentage that had remained unidentified," said Eckburg. "Despite this large effort, we are still not approaching the ...

Man-made wetland's effectiveness similar to natural marsh

...ecome a phosphorus source. "Wetlands' capacity to store phosphorus declines with time," Mitsch said. "But a wetland that reaches that point has extremely rich soil, which could be harvested and spread over a farm field. Or the wetland itself could be turned into a field again, assuming there are other wet...

UCLA scientists store materials in cells natural vaults

...e exploited thousands of tiny capsules in cells to store vast amounts of biomaterial. Dubbed vaults ?for their high arches reminiscent of cathedral ceilings ?these naturally occurring capsules may prove less likely to elicit an immune response than foreign carriers like viruses. IMPACT: The UCLA discovery...

Defenseless plants arm themselves with metals

...roup of plants, called metal hyperaccumulators, to store high levels of metal in their tissues, rendering them pathogen resistant. These findings, reported in today's (Friday, March 11) issue of the journal Plant Physiology, shed new light on the evolution of these plants and may have implications for the...

Revolutionary nanotechnology illuminates brain cells at work

...is involved with emotional reactions, and it helps store learned information in memory. When neurons are activated, they secrete glutamate, and we could see this activity under the microscope by watching the color change. We stimulated the neurons and watched them secrete glutamate in response. We also saw...

Disease diagnosis, biodefense among UH chemical research projects

...ily of heme proteins found in certain insects that store nitric oxide (NO). Having importance in many areas of human health, NO is useful in lowering blood pressure, treating cancer and increasing oxygen absorption in lung tissue. Czernuszewicz's research is focused on the roles of salivary nitrophorins in...

Iron exporter revealed that may explain common human disorder

...ron they contain. Macrophages and liver cells also store any excess iron. Earlier work had identified a single protein that imports iron into cells. However, the evidence for ferroportin's role in exporting iron back out of cells remained indirect. To determine which cells depend on ferroportin, the resea...

Sexual cooperation: Mating increases longevity in ant queens

... mate only during a short period early in life and store and use the sperm of their mate for the rest of their lives. Sexual offspring are only produced after several months or years of colony growth, during which a sterile worker force is built up in the population. The fact that mates bond so early reduc...

X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

RNA project to create language for scientists worldwide

...o make proteins." They are unique in being able to store and transmit information as well as process that information. The continuous discovery of new RNA molecules with novel biological functions is beginning to show that RNA plays far more roles than originally believed. For instance, while genomicists ...

Newly-discovered class of genes determines ?and restricts ?stem cell fate

...ic development of melanocytes ?cells that make and store the pigments in the skin and hair ?is also expressed in adult stem cells in the skin. "Our findings told us that a recapitulation of an embryonic program is occurring in resident stem cells in adult skin," explains Jon Epstein, MD, Professor of Medi...
