Yeast provides new insight into cholesterol-lowering drugs

Having discovered how a lowly, single-celled fungus regulates its version of cholesterol, Johns Hopkins researchers are gaining new insight about the target and action of cholesterol-lowering drugs taken daily by millions of people to stave off heart attacks and strokes.

Protein-misfolding accelerates yeast evolution

Under stress, yeast cells can unleash a remarkable mechanism based on protein-misfolding that gives them new characteristics without requiring genetic mutations.

Researchers provide new evidence that aging can be slowed

New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age.

Researchers provide new insight into adaptive ability of cells

The Stowers Institute's Rong Li Lab has published findings that shed light on the ability of cells to adapt to disruptions to their basic division machineries - findings that may help explain how cancer cells elude the body's natural defense mechanisms or chemotherapy treatment.

Researchers identify a potentially universal mechanism of aging

Like our current financial crisis, the aging process might also be a product excessive deregulation.

Dieters could have a harder time fighting flu

In a study published in the November issue of the Journal of Nutrition, Gardner showed that mice with a calorie-restricted diet were more likely to die during the first few days of infection than mice with a normal diet. Caloric restriction is the practice of reducing the intake of calories to 40 percent of a normal diet, while maintaining adequate vitamins and minerals.

Scientists shed light on how DNA is unwound so that its code can be read

Researchers at The Scripps Research Institute have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell's nucleus so that genetic information can be "read" and used to direct the synthesis of proteins, which have many specific functions in the body.

Prion switching in response to environmental stress

If you have had a hard day at work, you may change your eating habits, perhaps favoring comfort food, but you don't suddenly develop the ability to eat the plate and cutlery.

Scientists find cells reorganize shape to fit situation

Flip open any biology textbook and you're bound to see a complicated diagram of the inner workings of a cell, with its internal scaffolding, the cytoskeleton, and how it maintains a cell's shape.

FDA strengthens safety of Sucraid (sacrosidase) oral solution

The U.S. Food and Drug Administration today issued an expedited approval of a supplemental application that allows for changes in the manufacturing of Sucraid (sacrosidase) Oral Solution.

New gene-silencing pathway found in plants

Biologists at Washington University in St. Louis have made major headway in explaining a mechanism by which plant cells silence potentially harmful genes.

New clue for cellular damage in Huntington's disease

"Huntington's disease presents an ideal vantage point to study neurodegenerative disease, because we know the misfolded protein that's responsible," says Martin Duennwald, formerly a postdoctoral researcher in the lab of Whitehead Member Susan Lindquist.

Researchers describe how cells recycle protein waste

Garbage collectors are important for removing trash; without them waste accumulates and can quickly become a health hazard.

Biologists identify genes that prevent changes in physical traits due to environmental changes

New York University biologists have identified genes that prevent physical traits from being affected by environmental changes.

New strategy to treat human infections caused by the yeast Candida albicans

Researchers at Georgetown University Medical Center (GUMC) have successfully tested a genetic strategy designed to improve treatment of human infections caused by the yeast Candida albicans, ranging from diaper rash, vaginitis, oral infections (or thrush which is common in HIV/AIDS patients), as well as invasive, blood-borne and life-threatening diseases.

Molecule stops DNA replication in its tracks

When a dividing cell duplicates its genetic material, a molecular machine called a sliding clamp travels along the DNA double helix, tethering the proteins that perform the replication.

Catching the blood cell bus gives fatal yeast infection a clean getaway

Yeast fungus cells that kill thousands of AIDS patients every year escape detection by our bodies' defences by hiding inside our own defence cells, and hitch a ride through our systems before attacking and spreading, scientists heard today (Tuesday 9 September 2008) at the Society for General Microbiology's 163rd meeting being held this week at Trinity College, Dublin.

Panacea Pharmaceuticals issued U.S. patent for anti-HAAH antibodies

Panacea Pharmaceuticals, Inc. has announced the issuance of U.S. Patent Number 7,413,737 covering antibodies against human aspartyl (asparaginyl) beta-hydroxylase (HAAH), a proprietary human cancer biomarker and therapeutic target.

Researchers show how DNA repairs may reshape the genome

Researchers at Duke University Medical Center and at the National Institute of Environmental Health Sciences (NIEHS) have shown how broken sections of chromosomes can recombine to change genomes and spawn new species.

Molecular bridge serves as a tether for a cell's nucleus

A cell's nucleus - home of it its most precious contents - is a delicate envelope that, without support, is barely able to withstand the forces that keep it in place. Now, researchers have discovered a network of molecules in the nuclear membrane that provide the nucleus with rigidity and also facilitate a previously undiscovered form of communication between the cell's nucleus and its cytoplasm.
