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.

Aspirin controls two key processes to kill bowel cancer cells

Aspirin kills cancer cells by controlling two key processes that influence energy use in cells and could explain how aspirin can prevent bowel cancer. The research is published in this month's Gastroenterology.

Scientists may be step closer to developing new therapy for AML

Scientists at Virginia Commonwealth University Massey Cancer Center may be one step closer to developing a new therapy for acute myeloid leukemia (AML) after discovering that the targeted agents obatoclax and sorafenib kill leukemia cells much more effectively when combined than when the drugs are administered individually.

Researchers develop potent new drug that can kill tumor cells

All cells have the ability to recycle unwanted or damaged proteins and reuse the building blocks as food. But cancer cells have ramped up the system, called autophagy, and rely on it to escape damage in the face of chemotherapy and other treatments. Now, researchers at the Perelman School of Medicine; the Abramson Cancer Center; and the School of Arts and Sciences, at the University of Pennsylvania, have developed a potent new drug that clogs up the recycling machinery and kills tumor cells in mouse models.

Combination of two mTOR inhibitors stops growth of hepatocellular carcinoma

The combination of two inhibitors of protein mTOR stops the growth of primary liver cancer and destroys tumour cells, according to a study by researchers of the Group of Metabolism and Cancer at Bellvitge Biomedical Research Institute.

Body’s own DNA can cause inflammation in the heart

DNA from the heart's own cells plays a role in heart failure by mistakenly activating the body's immune system, according to a study by British and Japanese researchers, co-funded by the British Heart Foundation.

Self-degradation response to antidepressant Zoloft observed in yeast cells

Princeton University researchers have observed a self-degradation response to the antidepressant Zoloft in yeast cells that could help provide new answers to lingering questions among scientists about how antidepressants work, as well as support the idea that depression is not solely linked to the neurotransmitter serotonin.

Autophagy potential target for new CF treatments

Scientists have found why a certain type of bacteria, harmless in healthy people, is so deadly to patients with cystic fibrosis.

Study: Kidney cancer growth depends on autophagy

New research at the University of Cincinnati (UC) suggests that kidney cancer growth depends on autophagy, a complex process that can provide cells with nutrients from intracellular sources. Researchers say in certain circumstances autophagy can protect tumor cells from chemotherapy, allowing them to survive for long periods of time in a hidden, dormant, metastatic state.

Combination treatment effective against melanoma

Research from The Cancer Institute of New Jersey (CINJ) shows that a coordinated effort to block signaling pathways that promote cancer cell growth and survival enhances programmed cell death in melanoma.

Penn oncologist to discuss role of autophagy in fighting cancer at AAAS annual meeting

Blocking autophagy -- the process of "self-eating" within cells -- is turning out to be a viable way to enhance the effectiveness of a wide variety of cancer treatments.

Scientists identify single prion protein that causes neuronal death

Scientists from the Florida campus of The Scripps Research Institute have identified a single prion protein that causes neuronal death similar to that seen in "mad cow" disease, but is at least 10 times more lethal than larger prion species.

Genoscience, BioLineRx to develop and commercialize BL-8020 for HCV

BioLineRx, a biopharmaceutical development company, announced today it has signed a worldwide, exclusive license agreement with Genoscience, a French company focused on viral disease therapeutics, to develop and commercialize BL-8020, an orally available treatment for Hepatitis C.

Exercise fails to improve glucose metabolism in autophagy-deficient mice

The health benefits of exercise on blood sugar metabolism may come from the body's ability to devour itself, UT Southwestern Medical Center researchers report in the journal Nature.

New cancer research findings presented at 53rd ASH annual meeting

Researchers from Seidman Cancer Center at University Hospitals (UH) Case Medical Center and Case Western Reserve University School of Medicine presented new research findings in 25 presentations this weekend at the 53rd Annual Meeting of the American Society of Hematology (ASH) at the San Diego Convention Center.

Cancer cells can 'bag up and bin' a toxic protein to cheat death

Cancer Research UK scientists have discovered that cancer cells can 'bag up and bin' a toxic protein to cheat death - revealing a new Achilles heel in cancer cells that could be targeted for treatment, reveals research in Nature Cell Biology today.

Chloroquine-chemotherapy combination holds potential for metastatic breast cancer treatment

An anti-malaria drug used for more than 60 years is now being studied for use in breast cancer patients whose disease has not responded to traditional chemotherapy treatment.

Cancer cells tap into natural recycling system to obtain energy

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that cancer cells tap into a natural recycling system to obtain the energy they need to keep dividing. In a study with potential implications for cancer treatments, Einstein researchers used genetic manipulation to turn off this recycling system within the walls of cells and stop both tumor growth and metastasis.

Lower glycemic index diet may delay onset of AMD-like lesions

Feeding older mice a lower glycemic index (GI) diet consisting of slowly-digested carbohydrates delays the onset of age-related, sight-threatening retinal lesions, according to a new study from the Laboratory for Nutrition and Vision Research at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University.
