Genetic defects give the immune system the green light to attack the pancreas

...iabetes. Their pancreatic beta cells can no longer make insulin. Without this crucial hormone, their body cannot convert food into energy. To sustain life, they must get insulin through injections. The disorder can emerge in childhood, adolescence and even appear in adulthood, but the genetic stage is set...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...h so far has used mouse oocytes but U-M expects to make the technology available in the clinic soon. "With traditional slow-freeze techniques, just over half the eggs survive the thawing process. Using vitrification, we are getting 98 percent survival. For a woman with cancer, these are the only eggs she...

Test for early detection of prostate cancer shows promise

... are under way to further refine the EPCA test, to make it more sensitive so it can pick up even the smallest traces of the marker, and to verify its usefulness for detecting prostate cancer in a larger sample of patients, said Getzenberg. Prostate cancer is the most common type of cancer found in Americ...

A puzzle piece found in unraveling the wiring of the brain

...ne named sec15 that is required for nerve cells to make appropriate choices of targets on which to act. The Sec15 protein is part of a protein complex (the exocyst) which is known to be required for secretion (or exocytosis) of vesicular compartments in yeast. Vesicular compartments are small organelles ...

Global analysis of membrane proteins

Scientists at Stockholm University have now mapped out nearly all of the membrane proteins in the enteric bacterium Escherichia coli. Their study is published this week in Science magazine. The team, led by professor Gunnar ...

Aggressive aquatic species invading Great Lakes

..., such as the logperch, is likely to fight hard to make sure it keeps its turf, but round gobies are extremely aggressive compared to the naturally occurring relatively peaceful logperch and easily take over contested shelters," explains Balshine. The researchers found that round goby abundance has incre...

New tumor-suppressor gene discovered

...aterial disrupted the gene's function, which is to make a particular protein that works in particular ways. "A mutant gene is not going to make the protein product that the normal gene is able to make," Lai explains. Lai then generated mutant ...

Insight into DNA's 'weakest links' may yield clues to cancer biology

...s or stalls. However, the DNA characteristics that make particular sites vulnerable to breakage had remained unclear, he said. The researchers slowed DNA replication in yeast cells by reducing the availability of one form of DNA polymerase, which are enzymes critical in DNA duplication. Yeast with abnorm...

Shutting down the HIV assembly line

...art in that each step along the way is required to make an infectious viral particle." Spearman's team has focused on a protein called "Gag," the major HIV structural protein. In recent years, Spearman said, it has become apparent that Gag moves to a compartment in the cell called the multivesicular body...

Protein helps regulate the genes of embryonic stem cells

In addition to Magnuson and Montgomery, department of genetics ...

The evolutionary triumph of flower power

In that sense they're like dogs. They are the pets of the plant world." Psychologist Haviland-Jones had conducted three studies that t...

Integration of Agilent's MS technology, Proteome Systems' software to help scientists in proteomics research

Double triumph in stem cell quest

Verlinsky says the cells express a number of ESC markers. His team has also shown the cells can differentiate into a number ...

At long last, scientists figure out how plants grow

...ey also expressed TIR1 in insect cell cultures, to make sure that the binding of TIR1 to auxin is not directly influenced by other plant cell proteins. Auxins influence a wide variety of plant processes. For example, they are the hormones that cause roots to grow downward and flowers to track the moving ...

The evidence of the barren ground grizzly bear (Ursus arctos) was discovered on Melville Island, an uninhabited part of the western Arctic archipelago 1,500 kilometres due north of Yellowknife, and 1,000 kilometres nort...
