Ribosomal proteins RPL5, RPL11 play essential role in normal cell proliferation

Researchers from the Laboratory of Cancer Metabolism (LCM) led by George Thomas at the Bellvitge Biomedical Research Institute (IDIBELL), the Catalan Institute of Oncology (ICO) and the Division of Hematology/ Oncology, University of Cincinnati, have shown that loss of either one of two tumor suppressors, ribosomal proteins RPL5 or RPL11, fail to induce cell-cycle arrest, but prevent the proliferation of cells as they have a reduced capacity to synthesize proteins.

Researchers examine how spindle apparatus self-organizes

Researchers at Waseda University in Japan have identified key information to help explain the formation of the "spindle apparatus", a structure required for cell division. Their findings shed light on the mechanisms behind "self-organization" - an essential characteristic of biological structures.

Findings highlight possible new approach to combat malaria

An international team of scientists, including researchers at Columbia University Medical Center, has identified a key metabolic enzyme that common malaria parasites require for survival at each stage of infection in humans. The findings raise the possibility of a new approach to combating malaria, one of the world's deadliest diseases. The study was published today in the online edition of the journal Nature.

Study uncovers mechanisms that allow stem cells to keep dividing in perpetuity

The blood stem cells that live in bone marrow are at the top of a complex family tree. Such stem cells split and divide down various pathways that ultimately produce red cells, white cells and platelets. These "daughter" cells must be produced at a rate of about one million per second to constantly replenish the body's blood supply.

Researchers identify progenitor cells that are vital for successful growth of healthy placenta

Dr. Hanna Mikkola and researchers at UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have identified a novel progenitor cell and a related cell communication pathway that are key to the successful growth of a healthy placenta.

Waseda University researchers observe molecular motors that play critical role in chromosome transport

Researchers at Waseda University in Japan have for the first time directly observed the “molecular motor”, called Xkid, that plays a critical role in facilitating the proper alignment of chromosomes during cell division. Their findings are expected to contribute greatly to elucidating the molecular mechanisms of chromosome segregation, a key aspect of the development of certain medical disorders including cancer and birth defects.

Researchers discover new human enzyme that facilitates DNA repair during DNA copying process

Every day, the human body produces new cells to regenerate tissues and repair those that have suffered injury. Each time this happens, the cells make copies of their DNA that they will pass on to the resulting daughter cells. This process of copying the DNA, also called replication, is very delicate, given that it can generate severe alterations in the DNA that are associated with malignant transformation or ageing.

Researchers on the way to find cure against African sleeping sickness

Researchers at Umeå University have identified drugs targeting infections of the parasite Trypanosoma brucei and are thereby well on the way to find a cure against African sleeping sickness. This is the kernel of a thesis, which will be publicly defended on 8 November 2013.

Cell Therapeutics presents preclinical study results of PIXUVRI at AACR-NCI-EORTC meeting

Cell Therapeutics, Inc. (CTI) today announced the presentation of findings from a preclinical study of PIXUVRI® (pixantrone) that suggest its mechanism of inducing tumor cell death is novel and distinct from that of anthracyclines such as doxorubicin.

Study: Pds5 proteins modulate behavior of cohesins to ensure proper division of cells

Cohesins are protein complexes that join the two copies of each chromosome-called sister chromatids-to ensure that they are shared fairly between the daughter cells during cell division. In this way, each daughter cell receives exactly the same genetic information from the parent cell.

Research findings may lead to new ways to combat cancer

The way cells divide to form new cells - to support growth, to repair damaged tissues, or simply to maintain our healthy adult functioning - is controlled in previously unsuspected ways UC San Francisco researchers have discovered.

Dartmouth researchers find that protein cyclin A plays important role in cell division process

In a study to be published in the journal Nature, two Dartmouth researchers have found that the protein cyclin A plays an important but previously unknown role in the cell division process, acting as a master controller to ensure the faithful segregation of chromosomes during cell division.

Professor to develop DNA sequencing technologies to search for long-range genome interactions

Why do some people develop disease while others with the same genetic mutation don't? For example, the National Cancer Institute estimates that women who inherit a harmful BRCA2 mutation have a 45 percent chance of developing breast cancer by age 70.

Bacterial strains that delay cell division might be used to design drugs that stop division entirely

In 1958 a group of scientists working in Denmark made the striking observation that bacterial cells are about twice as large when they are cultured on a rich nutrient source than when they are cultured on a meager one.

Penn State researchers find that protein changes can control gene functions

A Penn State-led research team has found that changes to proteins called histones, which are associated with DNA, can control whether or not a gene is allowed to function. The changes may be important in maintaining the genes' "expression potential" so that future cells behave as their parent cells did.

Cancer-linked mitosis: an interview with Professor Scott Kern, Johns Hopkins University School of Medicine

Mitosis is the process by which a cell gives rise to two daughter cells. It’s the basis behind the growth of the human body, the renewal of the human body as it ages, and unfortunately, the growth of cancers.

New stem cell discovery may help scientists replace damaged organs

Stem-cell researchers at UC San Francisco have found a key role for a protein called BMI1 that may help scientists direct the development of tissues to replace damaged organs in the human body.

Study shows disrupted micronuclei may prove to be a valuable tool for detecting cancer

Scientists studying cancer development have known about micronuclei for some time. These erratic, small extra nuclei, which contain fragments or whole chromosomes that were not incorporated into daughter cells after cell division, are associated with specific forms of cancer and are predictive of poorer prognosis.

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.
