Needling Chromosomes Reveals Cell Division Secret

By impaling individual chromosomes with glassneedles one thousandth the diameter of a human hair, a Duke Universitygraduate student has tested their "stickiness" to one another duringcell division. Her uncanny surgical skills have added a piece to thelarge and intricate puzzle of how one cell divides into two -- aprocess fundamental to all organisms.In the Dec. 14, 2004, issue of Current Bi...

Key mechanism in genetic inheritance during cell division identified

A key mechanism in the passing of genetic material from a parent cell to daughter cells appears to have been identified by a team of Berkeley researchers. Their study may explain how a complex of proteins, called kinetochores, can recognize and stay attached to microtubules, hollow fibers in the walls of biological cells that are responsible for the faithful segregation of chromosomes during cell...

Pair of cancer genes found to drive both cell migration and division

Johns Hopkins researchers have found that two genes already known to control cell movement are also needed for proper cell division. They report their findings in the April issue of Developmental Cell. The researchers discovered that the two genes are required for a dividing cell's halves to separate, raising the possibility that interfering with them could be helpful in stopping the uncon...

Hunt for human genes involved in cell division under way

A systematic search through human genes has begun at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. Working within the MitoCheck consortium that includes 10 other institutes throughout Europe, the EMBL scientists will silence all human genes, one-by-one, to find those involved in cell division (mitosis) and to answer fundamental questions of how cell division is regulate...

Sugar helps control cell division

Johns Hopkins scientists have discovered that a deceptively simple sugar is in fact a critical regulator of cells' natural life cycle. The discovery reveals that, when disturbed, this process could contribute to cancer or other diseases by failing to properly control the steps and timing of cell division, the researchers say. The findings are described in the Sept. 23 issue of the Journal...

UW-Madison scientists find a key to cell division

MADISON - A cellular structure discovered 125 years ago and dismissed by many biologists as "cellular garbage" has been found to play a key role in the process of cytokinesis, or cell division, one of the most ancient and important of all biological phenomena. The discovery of the function of the dozens of proteins harbored within this structure - which are necessary for normal cell divi...

Sugar Helps Control Cell Division

Johns Hopkins scientists have discovered that a deceptively simple sugar is in fact a critical regulator of cells' natural life cycle.// The discovery reveals that, when disturbed, this process could contribute to cancer or other diseases by failing to properly control the steps and timing of cell division, the researchers say. The sugar, known as O-GlcNAc (pronounced oh-...

Researchers Reverse Cell Division

US researchers have found a way to reverse the process of cell division. This process was initially thought to be unstoppable. This finding could be an important milestone in the fight// against cancer, in which cells divide uncontrollably. Researchers from the Oklahoma Medical Research Foundation have published their findings in the journal Nature. Cell division occurs about a million...

Division Among Delegates To Dilute UN's AIDS Plans: Activists

As diplomats lock horns over the declaration to be issued after today's UN meet on AIDS, activists and victims fear the outcome will fail to effectively contain the epidemic that has claimed 25 million lives so far.// Hours before the declaration is to be issued, UN Secretary General Kofi Annan asked diplomats not to negotiate away gains made in an earlier declaration in 2001. <b...

United Biotech Launches New Oncology Division

India-based United Biotech is diversifying into the oncology segment starting with the launch of its new oncology division at an initial// investment of $3.4 million.

This new division is set up in collaboration with Blausiegel, a Brazilian company, for its entire...

Understanding HIV Interference With Infected Cell Division

Montreal, July 12, 2007 Dr. Eric A. Cohen, a researcher at the IRCM (Institut de recherches cliniques de Montreal), and his team will publish on Friday, July 13, in PLoS Pathogens a discovery that could lead to the development of a new class of drugs to combat HIV. Human immunodeficiency virus type 1 (HIV-1) causes AIDS by depleting essential immune cells called CD4+T lymphocytes...
