Mathematical modeling proved critical in understanding latent stage of infections

Recurrent infection is a common feature of persistent viral diseases. It includes episodes of high viral production interspersed by periods of relative quiescence. These quiescent or silent stages are hard to study with experimental models. Mathematical analysis can help fill in the gaps.

Researchers demonstrate how EGF accelerates division of cell nucleus

Biologists at Heidelberg University have discovered new approaches for the treatment of cancer. They investigated how a special signalling molecule, the epidermal growth factor (EGF), stimulates the separation of chromosomes in the cell. The researchers were able to demonstrate that EGF accelerates the division of the cell nucleus, i.e. mitosis, as well as boosts precision in chromosome segregation.

Researchers explore biological processes of stem cell division

The human body contains trillions of cells, all derived from a single cell, or zygote, made by the fusion of an egg and a sperm. That single cell contains all the genetic information needed to develop into a human, and passes identical copies of that information to each new cell as it divides into the many diverse types of cells that make up a complex organism like a human being.

Study: Blocking certain enzymes in cell may prevent cancer cell division and growth

Blocking certain enzymes in the cell may prevent cancer cell division and growth, according to new findings from researchers at the Graduate School of Biomedical Sciences at the Icahn School of Medicine at Mount Sinai.

Scientists discover new agent that removes potentially dangerous cells

Pluripotent stem cells can turn, or differentiate, into any cell type in the body, such as nerve, muscle or bone, but inevitably some of these stem cells fail to differentiate and end up mixed in with their newly differentiated daughter cells.

Discovery reverses the prevailing model of how dividing cells monitor equal distribution of chromosomes

Ludwig researchers Arshad Desai and Christopher Campbell, a post-doctoral fellow in his laboratory, were conducting an experiment to parse the molecular details of cell division about three years ago, when they engineered a mutant yeast cell as a control that, in theory, had no chance of surviving. Apparently unaware of this, the mutant thrived.

High levels of blood cholesterol increase risk of AD and heart disease

Researchers at the Linda Crnic Institute for Down Syndrome and the University of Colorado School of Medicine have found that a single mechanism may underlie the damaging effect of cholesterol on the brain and on blood vessels.

Inflammation and epigenetics: an interview with Dr Belkina and Dr Denis, Boston University School of Medicine

Inflammation can be thought of as taking two major forms: acute or chronic. Acute inflammation, which can be painful, usually arises quickly and resolves quickly. It accompanies bacterial infections, traumatic injury and is useful to fight infections and promote healing.

Researchers discover likely origin of epithelial ovarian cancer

Cornell University researchers have discovered a likely origin of epithelial ovarian cancer (ovarian carcinoma), the fifth leading cause of cancer death among women in the United States.

SLU team discovers molecular pathway that contributes to triple-negative breast cancer

In research published in the Jan. 17 issue of The Journal of Cell Biology, a team led by Susana Gonzalo, Ph.D., assistant professor of biochemistry and molecular biology at Saint Louis University, has discovered a molecular pathway that contributes to triple-negative breast cancer, an often deadly and treatment resistant form of cancer that tends to strike younger women.

New details about molecular surveillance system that helps detect and correct errors in cell division

Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the current issue of the Journal of Cell Biology.

Klerokinesis may prevent some cancers from developing

Researchers at the University of Wisconsin Carbone Cancer Center have discovered a new form of cell division in human cells.

Ancient algae may hold key to treating malaria and related parasites

Researchers have discovered that parasites of the Apicomplexa taxon, such as Plasmodium falciparum and Toxoplasma gondii, reproduce within host cells using a structure that evolved from a flagellum.

New research provides unprecedented clarity to aging process

For the first time, scientists at Fred Hutchinson Cancer Research Center have defined key events that take place early in the process of cellular aging.

NIH awards $2.1M grant to study possible ways to fight cancer

A professor with the University of Houston Cullen College of Engineering has won a $2.1 million grant to study the best ways to modify human immune cells to fight against cancer.

Flow cytometry isolates stem cells from brain tumors

A new video protocol in Journal of Visualized Experiments (JoVE) details an assay to identify brain tumor initiating stem cells from primary brain tumors. Through flow cytometry, scientists separate stem cells from the rest of the tumor, allowing quick and efficient analysis of target cells. This approach has been effectively used to identify similar stem cells in leukemia patients.

Clathrin protein plays a key role in cell division

A protein called "clathrin," which is found in every human cell and plays a critical role in transporting materials within them, also plays a key role in cell division, according to new research at the University of California, San Francisco.

Parental methylated histones not transferred to daughter DNA

It's widely accepted that molecular mechanisms mediating epigenetics include DNA methylation and histone modifications, but a team from Thomas Jefferson University has evidence to the contrary regarding the role of histone modifications.

Orc1 mutations may explain pathology in manifestations of Meier-Gorlin syndrome

Research published Aug. 1 by scientists at Cold Spring Harbor Laboratory (CSHL) links gene mutations found in some patients with Meier-Gorlin syndrome (MGS) with specific cellular dysfunctions that are thought to give rise to a particularly extreme version of dwarfism, small brain size, and other manifestations of abnormal growth which generally characterize that rare condition.

Study investigates molecular markers in drug-resistant ovarian cancer

A new study by TCD researchers investigates drug-resistant ovarian cancer cells. The findings which have been recently published in the international publication, PLoS One will increase understanding of molecular markers in drug-resistant ovarian cancer with a view to improving clinical treatment.
