Post brain injury: New nerve cells originate from neural stem cells

Most cells in the human brain are not nerve cells, but supporting cells (glial cells).

Long-term effects of synthetic progestins cause for concern

The widely used synthetic progestin medroxyprogesterone acetate (MPA) decreased endothelial function in premenopausal women in a study done at the University of Oregon.

Device allows scientists to control gene activity across generations of cells

Just as cells inherit genes, they also inherit a set of instructions that tell genes when to become active, in which tissues and to what extent.

Enzyme Cdk1 may lead to new cancer therapies

With a four-year, $707,000 grant from the American Cancer Society, Yanchang Wang, assistant professor of biomedical sciences in the Florida State University College of Medicine, hopes to learn how a particular enzyme could possibly help put the brakes on the runaway cell division process that occurs in many forms of cancer.

Smoking's effects on genes may play a role in lung cancer development and survival

Smoking plays a role in lung cancer development, and now scientists have shown that smoking also affects the way genes are expressed, leading to alterations in cell division and regulation of immune response.

How a red blood cell loses its nucleus

Unlike the rest of the cells in your body, your red blood cells lack nuclei.

Location location location, even for genes

Moving an active gene from the interior of the nucleus to its periphery can inactivate that gene report scientists from the University of Chicago Medical Center in an article to be published early online Feb.13, 2008, in the journal Nature.

How red blood cells nuke their nuclei

Unlike the rest of the cells in your body, your red blood cells lack nuclei.

Researchers identify cells that cause nervous system disease

Two teams of University of Michigan researchers have tracked down the cells responsible for neurofibromatosis type1, a disfiguring, incurable condition and one of the most common hereditary disorders.

Neurogenesis plays an important role in the acquisition and storage of spatial memory

Boosted by physical and mental exercise, neural stem cells continue to sprout new neurons throughout life, but the exact function of these newcomers has been the topic of much debate.

Researchers unravel mystery of cell division

Experts in mitosis (cell division) at the University of Virginia Health System have made discoveries that explain how one protein the kinase Aurora B could have such a large role in guiding and policing the process of cell division.

Protein that controls hair growth also keeps stem cells slumbering

Like fine china and crystal, which tend to be used sparingly, stem cells divide infrequently.

Synthesis of natural molecule could lead to better anti-cancer drugs

In early 2007, Northwestern University chemist Karl Scheidt's interest was piqued when marine chemist Amy Wright reported in the Journal of Natural Products that a new natural compound derived from an uncommon deep-sea sponge was extremely effective at inhibiting cancer cell growth.

New anticancer drugs may block HSP90-IP6K2 protein interaction involved in cell death

Johns Hopkins researchers have discovered a previously unsuspected mechanism of cell death that may afford a new way to find and develop stronger yet less-harmful anticancer drugs.

German Research Foundation skeptical on cloning of human cells

According to a paper published in the journal Stem Cells, an American group has succeeded in inserting cell nuclei from human skin cells into human enucleated oocytes and to stimulate these new cells to undergo cell division in the laboratory.

Cell division studies hint at future cancer therapy

When a cell's assets get divided between daughter cells, Dr. Quansheng Du wants to make sure both offspring do well.

23 Jan 2008

High blood pressure gene found

Scientists have identified the gene that sets off a sequence of events in the blood vessels of otherwise healthy adults that can lead to high blood pressure.

Asf1, the protein that oversees DNA replication and packaging in the cell

At the Institut Curie, the CNRS team of Genevieve Almouzni has just discovered how the protein Asf1 ensures the correct (re)organization of duplicated DNA. During DNA replication, all the information in the mother cell must be transmitted to the daughter cells.

New insight into factors that drive muscle-building stem cells

A report in the January issue of Cell Metabolism, a publication of Cell Press, provides new evidence explaining how stem cells known as satellite cells contribute to building muscles up in response to exercise.

Discovery of 480 genes that control human cell division

A team of U.S., Israeli and German scientists used computational biology techniques to discover 480 genes that play a role in human cell division and to identify more than 100 of those genes that have an abnormal pattern of activation in cancer cells.
