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.

Researchers discover new function of genes in Fanconi anemia pathway

Researchers from UT Southwestern Medical Center have identified an important new function of genes in the Fanconi anemia pathway - a finding that could have implications for development of new therapies to treat this disorder and some cancers.

LAP defects may lead to lupus-like autoimmune disorder

A casual observation about size differences in mice has led to the discovery that defects in a process for digesting dead cells called LC3-associated phagocytosis (LAP) may lead to a lupus-like autoimmune disorder. St. Jude Children's Research Hospital scientists led the research, which appears as an advance online publication today in the scientific journal Nature.

Study describes precise mechanisms that enable TB bacteria to persist in the body

Bacteria that cause tuberculosis trick immune cells meant to destroy them into hiding and feeding them instead. This is the result of a study led by researchers from NYU Langone Medical Center and published online April 18 in Nature Immunology.

Neuroscientists decipher new pathway in stem cell differentiation

How do neurons become neurons? They all begin as stem cells, undifferentiated and with the potential to become any cell in the body.Until now, however, exactly how that happens has been somewhat of a scientific mystery. New research conducted by UC Santa Barbara neuroscientists has deciphered some of the earliest changes that occur before stems cells transform into neurons and other cell types.

WSU researcher explores new drugs to treat neurological disorders linked to autophagic dysfunction

Repairing the brain's "house-cleaning function," which could help people with Alzheimer's, Parkinson's, amyotrophic lateral sclerosis (ALS) and 100 other diseases, is the focus of recently funded research at Washington State University.

Researchers find new innate immunity pathway that protects mammals from viral oncogenesis

Building upon earlier research, investigators at UT Southwestern Medical Center and their collaborators have identified a new innate immunity pathway that protects mammals from viral oncogenesis, the process by which viruses cause normal cells to become cancerous.

Inhibition of mitochondrial calcium uptake specifically toxic to cancer cells

Inhibiting the transfer of calcium ions into the cell's powerhouse is specifically toxic to cancer cells, according to an article published this week in Cell Reports by researchers from the Perelman School of Medicine at the University of Pennsylvania.

UAB researchers focus on five key areas to improve care of CVD patients

According to the Centers for Disease Control and Prevention, approximately 610,000 people die of heart disease in the United States every year — that's one in every four deaths. The impact of cardiovascular diseases is quite large.

Intracellular process of autophagy plays role in prostate cancer development, shows research

Research from investigators at Rutgers Cancer Institute of New Jersey and the Herbert Irving Comprehensive Cancer Center at Columbia University Medical Center, shows the intracellular process of autophagy plays a role in the development of prostate cancer.

Fasudil improves memory in rats, promotes degradation of toxic tau in the eyes of fruit flies

Could a kinase inhibitor some doctors prescribe to keep blood flowing after brain surgery be used to treat neurodegeneration? New research suggests it might be worth exploring the question.

The mechanism behind protective cells protecting themselves

Researchers at St. Jude Children's Research Hospital have discovered the mechanism by which immune cells called regulatory T cells keep themselves intact and functional during their demanding task of holding the immune system in check. Such T cells are key to preventing the immune system from attacking the body in autoimmune disease.

Johns Hopkins study shows high doses of cocaine kill brain cells

Working with mice, researchers at Johns Hopkins have contributed significant new evidence to support the idea that high doses of cocaine kill brain cells by triggering overactive autophagy, a process in which cells literally digest their own insides. Their results, moreover, bring with them a possible antidote, an experimental compound dubbed CGP3466B.

Cholesterol essential for health, but also plays key role in longevity

Animals from tiny worms to human beings have a love-hate relationship with fats and lipids. Cholesterol is a famous example of how they are both essential for health and often have a role in death.

New CRC aims to better understand autophagy at molecular and cellular level

The German Research Foundation (Deutsche Forschungsgemeinschaft/DFG) has approved 11 M € for the next four years for establishing a CRC on selective autophagy under the lead of Goethe University. Autophagy literally means "self-eating" and refers to a sophisticated system in which cellular waste is specifically detected and removed.

Potential treatment strategy for glycogen storage disease

Researchers from the Duke-NUS Graduate Medical School Singapore and Duke Medicine have identified a potential treatment strategy for an often-fatal inherited glycogen storage disease.

New research shows that autophagy can operate in cell nucleus to guard against start of cancer

Autophagy, literally self-eating or the degradation of unwanted cellular bits and pieces by the cell itself, has been shown for the first time to also work in the cell nucleus. In addition, in this setting it plays a role in guarding against the start of cancer, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

New hope for patients with Duchenne muscular dystrophy

New hope for Duchenne muscular dystrophy (DMD) patients. A mouse genetic study in PLoS Medicine reports that targeting the P2RX7 gene, a purinoreceptor, may halt the progression of DMD.

New study finds link between maternal protein deficiency during pregnancy and metabolic diseases in offspring

A new study has uncovered the genetic processes that link insufficient protein consumption during pregnancy with the development of muscle problems in mothers and their male offspring.

Treating cancer cells with quizartinib inhibits key metabolic pathway, activates macroautophagy

A study published in The Journal of Cell Biology describes a way to force cancer cells to destroy a key metabolic enzyme they need to survive.

Four UC San Diego researchers selected to receive newly established NCI Outstanding Investigator Award

Four University of California, San Diego School of Medicine researchers have been selected to receive the newly established National Cancer Institute (NCI) Outstanding Investigator Award. The multi-million dollar awards fund new projects that have an unusual potential in cancer research over seven years.
