New study on behaviour of telomeres during cell division in cancerous human cells

A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. 7 issue of the journal Cell.

Research journal to host a webinar on apoptotic signalling in normal and cancer cell biology

The business office of Science, the world's leading peer-reviewed research journal, is producing a webinar on "Apoptotic Signaling in Normal and Cancer Cell Biology" to be broadcast live online at 12 noon ET (4:00 GMT) September 22, 2009, sponsored by Promega.

Chk1 and Fbx6 play an important role for the regulation of response to chemotherapy

Cell cycle checkpoints act like molecular tripwires for damaged cells, forcing them to pause and take stock. Leave the tripwire in place for too long, though, and cancer cells will press on regardless, making them resistant to the lethal effects of certain types of chemotherapy, according to researchers at the Salk Institute for Biological Studies.

Diabetics can reduce the risk of cardiovascular disease by increasing vitamin D levels

Low levels of vitamin D are known to nearly double the risk of cardiovascular disease in patients with diabetes, and researchers at Washington University School of Medicine in St. Louis now think they know why.

Researchers discover elusive nanoscale movements of ribosomes at work

Researchers at the University of California, Berkeley, have for the first time captured elusive nanoscale movements of ribosomes at work, shedding light on how these cellular factories take in genetic instructions and amino acids to churn out proteins.

Novel microRNA plays a major role in invasive breast cancer development

Research led by Suresh Alahari, PhD, Associate Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, has shown for the first time that a tiny piece of RNA appears to play a major role in the development of invasive breast cancer and identified a gene that appears to inhibit invasive breast cancer.

Scientists find another mechanism that destroys tumor cells

Cells don't like to be alone. In the early stages of tumor formation, a cell might be pushed out of its normal home environment due to excessive growth. But a cell normally responds to this homeless state by dismantling its nucleus, packing up its DNA, and offering itself to be eaten by immune system cells. Simply put, the homeless cell kills itself. This process, known as apoptosis, typically stops potential cancer cells before they have a chance to proliferate.

Steroid hormones found to affect gene activity

Intermittent signaling by steroid hormones can affect the way genes are expressed in rodents, according to research by scientists at the University of Bristol and the National Cancer Institute (NCI), USA. This work has major implications for understanding how steroids work and opens novel avenues for new therapies.

Protein Huwe1 may be an important factor in the development of brain cancer

Researchers from Columbia University Medical Center's Herbert Irving Comprehensive Cancer Center have identified a protein that activates brain stem cells to make new neurons - but that may be hijacked later in life to cause brain cancer in humans. The protein called Huwe1 normally functions to eliminate other unnecessary proteins and was found to act as a tumor suppressor in brain cancer.

An "off switch" for cancer

New insight into how human cells reproduce, published by cancer researchers at Michigan State University and the Van Andel Research Institute in Grand Rapids, could help scientists move closer to finding an "off switch" for cancer.

Discovery of a genetic mutation underlying late-onset Leigh syndrome

Researchers at the Montreal Neurological Institute and Hospital (The Neuro), McGill University have discovered a genetic mutation underlying late-onset Leigh syndrome, a rare inherited metabolic disorder characterized by the degeneration of the central nervous system.

Oxygen nanosensor could improve tumor imaging

A new material developed at the University of Virginia - an oxygen nanosensor that couples a light-emitting dye with a biopolymer - simplifies the imaging of oxygen-deficient regions of tumors. Such tumors are associated with increased cancer aggressiveness and are particularly difficult to treat.

'Nanobee' drug delivery to tumors

When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

Two significant advances in treating lung cancer

Dr. Glen Weiss of the Translational Genomics Research Institute (TGen) and Scottsdale Healthcare this week announced two significant advances in treating lung cancer at an international cancer research conference.

Discovery of common trigger in cancer and normal stem cell reproduction

Researchers at Stanford University School of Medicine have discovered, for the first time, a common molecular pathway that is used by both normal stem cells and cancer stem cells when they reproduce themselves.

GE Global Research Biosciences technology celebrated fifth anniversary

From creating a new business in digital pathology to developing next generation diagnostic imaging agents and life sciences tools that are breaking new ground in the detection and treatment of disease, the Biosciences technology organization at GE Global Research today celebrated its fifth anniversary.

Scientists create stem cells from developing sperm

The promise of stem cell therapy may lie in uncovering how adult cells revert back into a primordial, stem cell state, whose fate is yet to be determined. Now, cell scientists at the Johns Hopkins University School of Medicine have identified key molecular players responsible for this reversion in fruit fly sperm cells.

Scientists isolate protein that affects both the expression of genes and the transport of proteins

Scientists at UC Santa Barbara have isolated a unique protein that appears to have a dual function and could lead to a "boon in medicine." The findings are published in the August issue of the Journal of Cell Biology.
