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.

Viral RNA linked to human immune response

In its fight against an intruding virus, an enzyme in our immune system may sense certain types of viral RNA pairs, according to scientists.

New function for missing protein in Duchenne muscular dystrophy found

Researchers at the University of Minnesota and National Institutes of Health have identified a new function for the protein missing in people with the most common and ultimately lethal form of childhood muscular dystrophy.

Discovery of novel tumor suppressor

La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia. Myeloproliferative diseases are a group of disorders characterized by an overproduction of blood cells by the bone marrow and include chronic myeloid leukemia. Lymphoma and leukemia are cancers of the blood.

New clues about the roots of neurological disease

Switching off a key DNA repair system in the developing nervous system is linked to smaller brain size as well as problems in brain structures vital to movement, memory and emotion, according to new research led by St. Jude Children's Research Hospital scientists.

Autophagy helps HIV to proliferate

Not satisfied with simply thwarting its host's defensive maneuvers, HIV actually twists one to its advantage, based on new findings from Kyei et al. in the July 27, 2009 issue of the Journal of Cell Biology. Vojo Deretic and colleagues suggest that autophagy - a stress response process - helps HIV to proliferate and that conversely, blocking autophagy lessens HIV production.

Skin cancer researchers throw new light on tumour growth

Three researchers from the Dermatology Research Foundation at the University of Sydney have identified a compound produced by certain fatal skin cancer tumours, providing new hope for developing treatments.

New insight into apoptosis

A study by Nanyang Technological University (NTU)'s Assistant Professor Li Hoi Yeung, Assistant Professor Koh Cheng Gee and their team have made an important contribution to the understanding of the process that cells go through when they die. This process known as 'apoptosis' or programmed cell death, is a normal process in the human body which removes perhaps a million cells a second.

Handle with care: Telomeres resemble DNA fragile sites

Telomeres, the repetitive sequences of DNA at the ends of linear chromosomes, have an important function: They protect vulnerable chromosome ends from molecular attack.

MicroRNAs hold promise for treating diseases in blood vessels

A newly discovered mechanism controls whether muscle cells in blood vessels hasten the development of both atherosclerosis and Alzheimer's disease, according to an article published online today in the journal Nature.

Harnessing nanoparticles to track cancer cell changes

The more dots there are, the more accurate a picture you get when you connect them. Cancer researchers adopting that philosophy have developed a new imaging technology that could give scientists the ability to simultaneously measure as many as 100 or more distinct features in or on a single cell. In a disease such as cancer, that capability would provide a much better picture of what is going on in individual tumor cells.
