Specialized cellular structures may hold clues to health effects of psychological stress

How does psychological stress translate into physical health effects? A key piece of the puzzle may be found in specialized cellular structures known as mitochondria, according to a pair of articles in the January issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society.

			EXD2 enzyme facilitates protein production in mitochondria Researchers from the Genomic Instability and Cancer Laboratory at Institute for Research in Biomedicine (IRB Barcelona) have identified a key role for EXD2 in protein production in the mitochondria, the cellular organelles responsible for the majority of energy generation.

			Study reveals how devastating mitochondrial diseases strike families without any previous history Researchers have shown for the first time how children can inherit a severe - potentially fatal - mitochondrial disease from a healthy mother.

	Key Stages and Processes Involved in Autophagy Pathway This article reviews the main processes and stages involved in autophagy pathway – a complex process that is closely regulated at the molecular level and has a crucial housekeeping role.

	Why Should We Weigh Every Protein in the Human Body? Our mission is to advance the measurement of human proteins with greater precision, to bring to the world the benefits of absolute molecular specificity when it comes to interrogating proteins at the molecular level.

	Stain Free Imaging of Chemical Distribution in Biological Systems Raman spectroscopy is an information-rich, label-free, non-invasive imaging technique perfect for life sciences research.

	Study identifies how excess fat disrupts heart cells' ability to produce energy A University of Iowa study has identified how excess fat in the heart, a common feature in diabetes and obesity, can harm the cells' essential ability to produce energy.

	How fatal mitochondrial diseases may strike offspring of families with no history of the conditions Researchers from the Medical Research Council (MRC) have discovered how some children inherit a potentially life-threatening mitochondrial disease, despite being born to a healthy mother.

	Scientists discover direct physical contact between two key cellular structures Northwestern Medicine scientists have discovered that two key cellular structures, called mitochondria and lysosomes, come into direct contact with each other in the cell to regulate their respective functions.

	CHOP researchers explore effective nutritional therapies for mitochondrial disease Defects in mitochondria, the tiny structures that power our cells by functioning as biological batteries, cause an array of complex, often life-threatening disorders that can affect any and all organs and systems.

	Study uncovers potential targets for treatment of aggressive triple-negative breast cancers As part of a breast-cancer diagnosis, doctors analyze the tumor to determine which therapies might best attack the malignancy.

	Salk scientists identify molecular target of experimental Alzheimer’s drug The experimental drug J147 is something of a modern elixir of life; it's been shown to treat Alzheimer's disease and reverse aging in mice and is almost ready for clinical trials in humans.

	Viral replication process weak spot may help develop cure for infections Researchers at the Morgridge Institute for Research believe they have identified a weak spot in the replication process of positive-strand RNA viruses, which could yield treatment for viral infections such as Zika, Polio, Chikungunya, Hepatitis C and even common cold viruses.
