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.

OSU-CG12 agent kills cancer cells through energy restriction: Study

Cancer cells grow so fast that they can outstrip their blood supply, leaving them short of oxygen. The cells then produce energy in a way that needs less oxygen but more sugar.

Variant of ATG16L1 gene associated with higher risk for Crohn's disease

The ATG16L1 gene is located on chromosome 2 and encodes a protein involved in the formation of autophagosomes during autophagy. Autophagy is a cytoplasmic process that keeps a cell stable. Hampe et al first identified ATG16L1 as a Crohn's disease (CD) susceptibility gene in 2007, and many other studies have arisen since then. However, the definite relationship of variants of ATG16L1 with IBD remains unclear.

Renowned leaders to discuss latest findings in early-stage drug development for cancer

When people think of cancer treatment, chemotherapy infusions, injections and pills often come to mind. These treatments result from extensive research and testing in drug development. But how does the process begin?

PINC trial to test anti-malarial drug in women with DCIS

Can a drug that has been used to treat malaria for years possibly be used to treat breast cancer before it becomes invasive? That's what researchers at George Mason University's Center for Applied Proteomics and Molecular Medicine (CAPMM) and Inova Breast Care Institute (IBCI) are trying to prove.

ATM tumor-suppressor also recognizes damage caused by ROS and orders autophagy

ATM, a protein that reacts to DNA damage by ordering repairs or the suicide of the defective cell, plays a similar, previously unknown role in response to oxidative damage outside of the nucleus, researchers report this week in the online version of the Proceedings of the National Academy of Sciences.

New project to unravel secret lives of cancer cells may help produce new cancer therapies

A team of scientists from Princeton University and The Cancer Institute of New Jersey has embarked on a major new project to unravel the secret lives of cancer cells that go dormant and self-cannibalize to survive periods of stress. The work may help produce new cancer therapies to stem changes that render cancer cells dangerous and resistant to treatment.

MBL generates human monoclonal antibodies against pandemic A type influenza virus

Medical & Biological Laboratories Co., Ltd. (MBL), with the collaboration of Osaka University, has successfully generated several fully human monoclonal antibodies against pandemic A (H1N1 and H3N2) type influenza virus by utilizing blood samples from volunteers who were inoculated with influenza vaccine.

IKK phosphorylate: A double-edged sword in Huntington's disease

The kinase IKK phosphorylates the protein mutated in Huntington's disease to promote its removal and neuron survival, but IKK may be a double-edged sword that increases neurotoxicity in later stages of the disease. The study, led by researchers from the University of California, Irvine, will be published online December 21 in the Journal of Cell Biology (www.jcb.org).

Arno Therapeutics announces dosing of first patient in Phase II clinical study of AR-67

Arno Therapeutics, Inc., a clinical-stage biopharmaceutical company focused on developing oncology therapeutics, today announced the dosing of the first patient in a Phase II clinical study of its third-generation camptothecin compound, AR-67, in patients with Glioblastoma Multiforme (GBM), an aggressive form of brain cancer.

Mutant ATPase blocks autophagy partway and causes multi-tissue degenerative disease

It's important to finish what you start, say Jeong-Sun Ju and researchers from Washington University School of Medicine, St. Louis. In the December 14, 2009 issue of the Journal of Cell Biology (www.jcb.org), Ju et al. reveal how a mutant ATPase blocks autophagy partway through to cause a multi-tissue degenerative disease.

Presentation of preclinical data demonstrating the combination of ISTODAX and Velcade announced

Gloucester Pharmaceuticals announced today the presentation of preclinical data demonstrating that the combination of ISTODAX® (romidepsin) and Velcade® (bortezomib) resulted in synergistic anti-tumor activity in B-cell non-Hodgkin's lymphoma cell lines.

Mutated IDH1 gene has novel enzyme activity consistent with cancer-causing gene: Study

Agios Pharmaceuticals today announced that its scientists have established, for the first time, that the mutated IDH1 gene has a novel enzyme activity consistent with a cancer-causing gene, or oncogene. This breakthrough discovery shows that the mutated form of IDH1 produces a metabolite, 2-hydroxyglutarate (2HG), which may contribute to the formation and malignant progression of gliomas, the most common type of brain cancers.

AACR-NCI-EORTC conference highlights major expansion in cancer drug pipeline

To highlight results of more recent research, the AACR-NCI-EORTC Molecular Targets and Cancer Therapeutics International Conference will host a press briefing on "Drugs in the Pipeline." Sara A. Courtneidge, Ph.D., D.Sc., professor and director of the Tumor Microenvironment Program, and director of academic affairs at the Burnham Institute for Medical Research, will moderate this press briefing.

HDAC inhibitors: New therapy for treating breast cancer

A powerful new breast cancer treatment could result from packaging one of the newer drugs that inhibits cancer's hallmark wild growth with another that blocks a primordial survival technique in which the cancer cell eats part of itself, researchers say.

Study: HSP inhibitor could stop tumor formation and extend survival

Like yoga for office drones, cells do have coping strategies for stress. Heat, lack of nutrients, oxygen radicals - all can wreak havoc on the delicate internal components of a cell, potentially damaging it beyond repair. Proteins called HSPs (heat shock proteins) allow cells to survive stress-induced damage. Scientists have long studied how HSPs work in order to harness their therapeutic potential.
