Protein can nurture or devastate brain cells, depending on its 'friends,' UT Southwestern researchers find

Researchers at UT Southwestern Medical Center have uncovered new insights into the "Dr. Jekyll and Mr. Hyde" nature of a protein that stimulates stem-cell maturation in the brain but, paradoxically, can also lead to nerve-cell damage.

Astragalus root plant chemical used to fight HIV

Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division.

Researchers discover metabolic deficiency in pancreatic cancer

UC Davis Cancer Center researchers have discovered a metabolic deficiency in pancreatic cancer cells that can be used to slow the progress of the deadliest of all cancers.

Researchers discover how Sonic hedgehog gene controls brain development

University of Pennsylvania School of Medicine researchers have discovered how the expression of the Sonic hedgehog gene is regulated during brain development and how mutations that alter this process cause brain malformations. The results appear online this month in Nature Genetics.

Novel cell division mechanism discovered

A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. The study is published today in the online version of the journal of the American National Academy of Sciences, PNAS.

Newly discovered mechanism can explain the Beckwith-Wiedemann syndrome

Researchers from Uppsala University have discovered a mechanism that silences several genes in a chromosome domain. The findings, published in today's on-line issue of Molecular Cell, have implications in understanding the human disorder Beckwith-Wiedemann syndrome.

Landmark study unlocks stem cell, DNA secrets to speed therapies

In a groundbreaking study led by an eminent molecular biologist at Florida State University, researchers have discovered that as embryonic stem cells turn into different cell types, there are dramatic corresponding changes to the order in which DNA is replicated and reorganized.

Sea birds' DNA may hold keys to aging and cancer, Bucknell researcher says

Chances are, a mouse in the wild will live less than a year before stumbling upon a hungry falcon or feline.

Research provides new insights into how cells accessorize their proteins

St. Jude Children's Research Hospital investigators have gained new insight into how the cell's vast array of proteins would instantly be reduced to a confusion of lethally malfunctioning molecules without a system for proteins to "accessorize" in order to regulate their function.

Squirrels may know a cure for cancer!

Scientists in the United States believe they have discovered a previously unknown anti-cancer mechanism in some rodents.

Discovery of tumour growth enzyme could lead to new cancer drugs

Scientists say a landmark study has revealed an enzyme which is vital to the growth of many cancers.

A fitness test for DNA

Unusually high levels of physical exertion do cause oxidative stress, but this does not result in any long-term damage to DNA. This is just one of the many outcomes revealed by an extraordinary research project funded by the Austrian Science Fund FWF that are now published. As part of this project, 42 male athletes took part both in a triathlon and an extensive biomedical study, which examined numerous physiological values parameters during the period from two days before to 19 days after the triathlon.

ICMT enzyme shows potential as target in treating blood cancer

A discovery by a research team with the Sahlgrenska Academy at Gothenburg University in Sweden may lead to new treatments for blood cancer and other diseases. By stopping the production of a specific enzyme, ICMT, researchers were able to alleviate disease symptoms in mice with blood cancer.

Australian researchers reveal how cancers become more aggressive

A team of Australian scientists have discovered how some cancers are able to mutate into more aggressive and potentially fatal cancers in the human body.

Finding cancer's original cell key to treatments

Cancer biologists are turning their attention to the normal cells that give rise to cancers, to learn more about how tumor growth might be stopped at the earliest opportunity.

Cancer survival secrets discovered by Australian researchers

A team of Monash University researchers has uncovered the role of a family of enzymes in the mutation of benign or less aggressive tumours into more aggressive, potentially fatal, cancers in the human body.

Researchers solve structure of enzyme vital for DNA repair

When dividing cells copy their DNA, mistakes can - and do - occur. To compensate, cells have a built-in system to correct these errors. That correction process isn't thoroughly understood, but researchers are piecing it together bit by bit.

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.

Researchers show how new chemotherapy drugs kill cancerous tumors

Dr Stephen Taylor and Karen Gascoigne at the University of Manchester's Faculty of Life Sciences have taken a new systematic approach to studying anti-mitotic drugs, which are used extensively for breast or ovarian cancer in the UK.
