Abnormal cell division explained

Why do some cancer cells divide not into two, as cells are supposed to do in mitosis, but into three-four new cells that look thoroughly abnormal? This question was raised as early as the 1890s by the German tumor researcher David Hansemann, who could observe the strange mitosis even using the microscopes of his day. Now another David, Lund University researcher David Gisselsson, has found an answer.

Protein Mnd2 protects chromosome bonds

The protein Mnd2 inhibits premature separation of chromosomes during the formation of gametes. The now published discovery of this regulatory function may help to understand the origin of some common congenital chromosome defects.

Needling chromosomes yields insights into cell division

By impaling individual chromosomes with glass needles one thousandth the diameter of a human hair, a Duke University graduate student has tested their "stickiness" to one another during cell division. Her uncanny surgical skills have added a piece to the large and intricate puzzle of how one cell divides into two -- a process fundamental to all organisms.

New link between a specific protein and its role in determining how cancerous cells divide

Biology researchers at Rutgers-Newark have identified a new link between a specific protein and its role in determining how cancerous cells divide, spread and form new tumors in other parts of the human body.

8.5 million Euros to address a fundamental question on mitosis: How is cell division regulated?

Scientists at the European Molecular Biology Laboratory (EMBL) join forces with top scientists from eleven research institutes in Austria, Germany, Italy, France and the United Kingdom for “MitoCheck” – the largest integrated research project on cell cycle control within the European Commission’s 6th Framework Programme (FP6).

African-American women less likely to survive breast cancer than white women

A new study led by investigators at Fred Hutchinson Cancer Research Center may help explain why African-American women with breast cancer are more likely to be diagnosed with advanced disease and are less likely to survive the disease than white women.

Protein on the centrosome key to new strategies for stopping cancer growth

A Mayo Clinic discovery about a protein known as Dynamin-2 has thrown conventional wisdom for a loop. Finding the protein on the centrosome, a minute structure near a cell’s nucleus, may lead to new strategies for stopping cancer growth.
