Suppressing cancer with a master control gene

Starting with the tiny fruit fly and then moving into mice and humans, researchers at VIB and K. U. Leuven show that expression of the same gene suppresses cancer in all three organisms. Reciprocally, switching off the gene - called Ato in flies and ATOH1 in mammals - leads to cancer.

Researchers study Actin - a globular protein

Actin, a globular protein found in all eukaryotic cells, is a workhorse that varies remarkably little from baker's yeast to the human body.

Scientists deconstruct cell division

The last step of the cell cycle is the brief but spectacularly dynamic and complicated mitosis phase, which leads to the duplication of one mother cell into two daughter cells.

Scientists discover missing link in the way cells protect themselves against cancer

Cancer Research UK scientists have discovered a missing link in the way cells protect themselves against cancer, according to research published in Genes & Development.

Leaky membranes: Another sign of old age

As parts of us age, even the membrane bound nuclei , which house the genetic instructions for life that are "written" in our DNA, begin to show considerable wear and tear, suggests a new report in the January 23rd issue of the journal Cell, a Cell Press publication.

Gene provides hope for restoring injured nerves

University of Utah scientists identified a worm gene that is essential for damaged nerve cells to regenerate, and showed they could speed nerve regeneration by over-activating the gene - a step toward new treatments for nerves injured by trauma or disease

MRSA's weak point visualised by scientists

An enzyme that lives in Methicillin-resistant Staphylococcus aureus (MRSA) and helps the dangerous bacterium to grow and spread infection through the human body has been visualised for the first time, according to a study out today in Proceedings of the National Academy of Sciences (PNAS).

Variations in mismatch repair genes predict prognosis in pancreatic cancer

Variations in mismatch repair genes can help predict treatment response and prognosis in patients with pancreatic cancer, according to research from The University of Texas M. D. Anderson Cancer Center presented today in advance of the American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium.

Biologists discover link between CGG repeats in DNA and neurological disorders

Researchers have long known that some repetitive DNA sequences can make human chromosomes "fragile," i.e. appearing constricted or even broken during cell divisions.

Researchers find link between two aging pathways in mice

Two previously identified pathways associated with aging in mice are connected, say researchers at the Stanford University School of Medicine.

Gene named scrawny keeps stem cells healthy

Stem cells are the body's primal cells, retaining the youthful ability to develop into more specialized types of cells over many cycles of cell division.

Genetic mutation causes familial susceptibility for degenerative brain disease acute necrotizing encephalopathy

Mutation of a gene that helps proteins migrate in and out of the cell's genetic command center - the nucleus - puts some families at higher risk for the degenerative brain disease acute necrotizing encephalopathy (ANE).

New insight into critical molecular mechanisms involved in aggressive childhood cancer

A new study reveals critical molecular mechanisms associated with the development and progression of human neuroblastoma, the most common cancer in young children.

Discovery of new tumor suppressor for lung cancer

Cancer and cell biology experts at the University of Cincinnati (UC) have identified a new tumor suppressor that may help scientists develop more targeted drug therapies to combat lung cancer.

Researchers identify gene linked to inherited form of fatal lung disease

Researchers at UT Southwestern Medical Center have determined that a mutation in a gene known for its role in defending the lungs against invading pathogens is responsible for some inherited cases of a lethal lung disease affecting older adults. The same mutation may also be associated with lung cancer, the researchers said.
