Autophagy News and Research

RSS

Autophagy is a normal process in which a cell destroys proteins and other substances in its cytoplasm (the fluid inside the cell membrane but outside the nucleus), which may lead to cell death. Autophagy may prevent normal cells from developing into cancer cells, but it may also protect cancer cells by destroying anticancer drugs or substances taken up by them.

Aging gracefully requires taking out the trash

Suppressing a cellular cleanup-mechanism known as autophagy can accelerate the accumulation of protein aggregates that leads to neural degeneration.

Customized virus kills brain tumor stem cells that drive lethal cancer

A tailored virus destroys brain tumor stem cells that resist other therapies and cause lethal re-growth of cancer after surgery, a research team led by scientists at the University of Texas M. D. Anderson Cancer Center reports in the Sept. 18 edition of the Journal of the National Cancer Institute.

Autophagy-induced signals are essential for normal development

A cannibalistic process called autophagy spurs dying embryonic stem cells to send "eat me" and "come get me" signals to have their corpses purged, a last gasp that paves the way for normal mammalian development, UT Southwestern Medical Center researchers have found.

Autophagy may accelerate decompensated heart failure

Autophagy, a normal process by which cells eat their own proteins to provide needed resources to the body in times of stress, may paradoxically cause harm to hearts already weakened by disease, researchers from UT Southwestern Medical Center have found.

Scientists link cell's protein recycling systems

Many age-related neurological diseases are associated with defective proteins accumulating in nerve cells, suggesting that the cell's normal disposal mechanisms are not operating correctly.

Largest ever genetics study of common diseases

The Wellcome Trust Case Control Consortium, the largest ever study of the genetics behind common diseases such as diabetes, rheumatoid arthritis and coronary heart disease, publishes its results in the journals Nature and Nature Genetics.

Insights into a key strategy cancer cells use to survive and thrive

The discovery of how some abnormal cells can avoid a biochemical program of self-destruction by increasing their energy level and repairing the damage, is giving investigators at St. Jude Children's Research Hospital insights into a key strategy cancer cells use to survive and thrive.

New compounds promising candidates for neurodegenerative disease drug development

Scientists have developed a novel strategy for tackling neurodegenerative diseases such as Huntington's disease: encouraging an individual's own cells to "eat" the malformed proteins that lead to the disease.

New genetic risk factors for Crohn's disease

An international research team , including investigators from Massachusetts General Hospital (MGH) and the Broad Institute of Harvard University and Massachusetts Institute of Technology, has identified several novel genetic variations associated with the risk of Crohn's disease.

Protection for nerve cells - eating up defective proteins

Nerve cells in the Central Nervous System can defend against and recover from damage by proteinlike clusters which are associated with neurodegenerative diseases such as Huntington's Chorea.

An engineered virus that tracks down and compels cancer cells to eat themselves

An engineered virus tracks down and infects the most common and deadly form of brain cancer and then kills tumor cells by forcing them to devour themselves, researchers at The University of Texas M. D. Anderson Cancer Center report.

Ginger shown to zap ovarian cancer cells

Researchers from the University of Michigan Comprehensive Cancer Center have found in a study that ginger kills cancer cells and has the added benefit of stopping the cells from becoming resistant to treatment.

Ginger causes ovarian cancer cells to die

Ginger is known to ease nausea and control inflammation. But researchers at the University of Michigan Comprehensive Cancer Center are investigating a new use for this age-old remedy: treating ovarian cancer.

Autophagy is also cell's second line of defense against invading pathogens such as strep

Cells give up their secrets slowly. Just when you think that all major cellular systems are understood, along comes a surprise. The latest is about autophagy, a major pathway for degrading and recycling within cells.

Autophagy may even provide a clue to the mythical fountain of youth

The cells of higher organisms have an internal mechanism for chewing up and recycling parts of themselves, particularly in times of stress, like starvation and disease. But nobody is quite sure yet whether this recently discovered process protects cells, or causes damage.
