Mitochondria essential for cellular ageing

An international team of scientists has for the first time shown that mitochondria, the batteries of the cells, are essential for ageing.

U.S. panel endorses “three-parent” IVF technique

An expert committee have recommended that the U.S. government allows the clinical investigation of mitochondrial replacement techniques (MRT) to go ahead.

New treatment could stop progression of ALS

Researchers at Oregon State University announced today that they have essentially stopped the progression of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, for nearly two years in one type of mouse model used to study the disease - allowing the mice to approach their normal lifespan.

New prognostic biomarker may help determine risk of prostate cancer-related death

Researchers at the University of Copenhagen have identified a new prognostic biomarker: the neuropeptide pro-NPY, which may help determine the risk of dying from prostate cancer. This particular type of protein is very specific to prostate cancer cells and could help identify whether newly diagnosed patients require radical prostatectomy surgery or if it is safe to delay surgery.

Levels of mitochondrial DNA in the blood may predict chronic kidney disease risk

The health of blood cells' energy-producing mitochondria may predict a person's risk of developing chronic kidney disease (CKD), according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology.

Immune killer cells use microptosis pathway to kill intracellular parasites

The immune system's killer cells deliver a tightly controlled, 3-phase knockout punch that kills intracellular parasites through a novel pathway that an international team led by researchers from the Program in Cellular and Molecular Medicine (PCMM) at Boston Children's Hospital have named "microptosis."

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.

New discovery may help researchers tackle mitochondrial diseases and age-related diseases

Buck Institute faculty Judith Campisi, PhD, says age researchers need to stop thinking of cellular senescence, now accepted as an important driver of aging, as a single phenotype that stems from genotoxic stress. Research from her lab reveals that cellular senescence, a process whereby cells permanently lose the ability to divide, is also induced by signaling from dysfunctional mitochondria - and that the arrested cells secrete a distinctly different "stew" of biologically active factors in a process unrelated to the damaging free radicals that are created in mitochondria as part of oxygen metabolism.

New mechanism of differentiation may offer novel therapeutic approaches to blood malignancies, solid tumors

In humans the differentiation of stem cells into hundreds of specialized cell types is vital. Differentiation drives development from fertilized egg to a newborn, and it underlies the continuous replacement of the 5 billion cells that die every hour in an adult. On the downside, mutations in differentiation pathways of different cell types can be drivers of cancers.

Three new genetic associations identified for primary open angle glaucoma

Researchers from Massachusetts Eye and Ear/Harvard Medical School and Case Western Reserve University School of Medicine have led an international effort to identify three genetic associations that influence susceptibility to primary open angle glaucoma -- the most common form of adult onset glaucoma and the leading cause of irreversible blindness in the world.

NIH-funded analysis identifies three genes that contribute to most common form of glaucoma

An analysis funded by the National Eye Institute (NEI), part of the National Institutes of Health, has identified three genes that contribute to the most common type of glaucoma. The study increases the total number of such genes to 15.

Insulin-producing cells' mitochondria may represent useful therapeutic target in type 2 diabetes

Factors in the blood from calorie-restricted rats can modify energy-producing mitochondria within the insulin-producing cells that regulate blood sugar levels, new research shows. This has a positive impact on glucose-stimulated insulin secretion and protects cells from fatty acid and glucose toxicity.

Eliminating the 'bad seeds' of liver cancer

Researchers have found the 'bad seeds' of liver cancer and believe they could one day reprogram them to remain responsive to cancer treatment, a new study has found.

Genetic mutation in starlings could shed light on mitochondrial disease in humans

Deakin University and UNSW Australia researchers have made a rare observation of rapid evolution in action in the wild, documenting the spread of a newly arisen genetic mutation in invasive starlings, which could shed light on mitochondrial disease in humans.

Father-daughter duo co-author research paper on new grapefruit cybrids

When Jude Grosser's daughter, Melinda, was in elementary school, he would often take her to his laboratory at the University of Florida's Citrus Research and Education Center, where he works as a researcher on citrus diseases and creating new varieties.

New study suggests that musclin may promote muscle health

A new study in mice shows that exercise causes muscle to release a peptide that builds the muscle's capacity for energy production and increases physical endurance, allowing for longer and more intense exercise.

Scientists reveal major players in severe muscle damage caused by sepsis

Scientists from the Institut Pasteur, Paris Descartes University, Sainte-Anne Hospital and the CNRS have recently published a paper in Nature Communications in which they reveal major players in the severe muscle damage caused by sepsis, or septicemia, which explains why many patients suffer debilitating muscle impairment long-term after recovery.

Mitochondrial variation and viable pregnancy: an interview with Dr Elpida Fragouli

Embryos require adequate amounts of energy so that they can successfully progress through each of their cell divisions.

Existing compound offers hope for slowing Huntington's disease progression

Currently, there is no treatment to halt the progression of Huntington's disease (HD), a fatal genetic disorder that slowly robs sufferers of their physical and mental abilities. Now, researchers at University of California, San Diego School of Medicine have discovered that an existing compound, previously tested for diabetes, offers hope for slowing HD and its symptoms.

New model of arterial thrombus formation is similar to popular video game

A group of biophysicists, including representatives from MIPT, has developed a mathematical model of arterial thrombus formation, which is the main cause of heart attacks and strokes.
