Dynamics of the mitochondria linked to obesity

Becoming obese or remaining lean can depend on the dynamics of the mitochondria, the body's energy-producing "battery," according to two new studies by Yale School of Medicine researchers featured as the cover story in the Sept. 26 issue of the journal Cell.

Disease Twofer: Parkin Problem Leads To Parkinson’S And Impairs Response To TB

University of California, San Francisco researchers report that a key protein associated with Parkinson's disease also plays a major role in the destruction of the bacteria that cause tuberculosis.

BESTCILIA project aims to improve screening, treatment of Primary Ciliary Dyskinesia

Primary Ciliary Dyskinesia is mainly a lung disease: a rare, genetically heterogeneous disorder resulting from dysfunction of small hair-like organelles (cilia) that clean the upper and lower airways. It can also affect multiple organs beside the respiratory system, and may cause serious impairment and lower quality of life. Its prevalence is estimated to be about 1 in 16,000.

Kinetin stops the effects of Parkinson's disease on brain cells, say scientists

The active ingredient in an over-the-counter skin cream might do more than prevent wrinkles. Scientists have discovered that the drug, called kinetin, also slows or stops the effects of Parkinson's disease on brain cells.

New treatment technique uses nanoparticles to attack cancer

Researchers at the University of Georgia are developing a new treatment technique that uses nanoparticles to reprogram immune cells so they are able to recognize and attack cancer. The findings were published recently in the early online edition of ACS Nano.

ASU expert receives $1.6 million grant to advance microscopy imaging research

At Arizona State University's Biodesign Institute, Nongjian (NJ) Tao has been designing advanced microscopy methods with the ambitious aim of capturing molecular-scale phenomena in living systems. The new techniques, which combine multiple imaging modalities, are poised to revolutionize the study of biology and the development of new drugs.

Scientists discover molecular switch that determines death or survival of cell

The study is the result of a collaboration of scientists at Karolinska Institutet in Sweden, University of Michigan, and University of California San Diego, USA, who were interested in finding out whether autophagy can be affected by events in the cell nucleus. Surprisingly, they discovered that a signal chain in the nucleus serves as a kind of molecular switch that determines whether the cell dies or survives.

Scientists uncover easy strategies to prevent harmful side-effects of antibiotics responses

A team of scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University has discovered why long-term treatment with many common antibiotics can cause harmful side effects-and they have uncovered two easy strategies that could help prevent these dangerous responses.

Researchers reveal how disease mutations affect the stability and function of Parkin protein

Researchers at the MRC Laboratory of Molecular Biology in the United Kingdom have determined the crystal structure of Parkin, a protein found in cells that when mutated can lead to a hereditary form of Parkinson's disease.

Scientists discover new function of an enzyme that disposes of superfluous proteins

Cells have a sophisticated system to control and dispose of defective, superfluous proteins and thus to prevent damage to the body. Dr. Katrin Bagola and Professor Thomas Sommer of the Max Delbr-ck Center for Molecular Medicine Berlin-Buch as well as Professor Michael Glickman and Professor Aaron Ciechanover of Technion, the Technical University of Israel in Haifa, have now discovered a new function of an enzyme that is involved in this vital process.

EGFR gums up cell's miRNA-processing machinery under oxygen starvation conditions

Even while being dragged to its destruction inside a cell, a cancer-promoting growth factor receptor fires away, sending signals that thwart the development of tumor-suppressing microRNAs before it's dissolved, researchers reported in an early online publication at Nature.

New research shows dysfunctional mitochondria in brain cells can lead to learning disabilities

Neuroscientist Patrik Verstreken of VIB (Flanders Institute for Biotechnology) and KU Leuven has shown for the first time that dysfunctional mitochondria in brain cells can lead to learning disabilities.

Mouse study shows leukemia halts accumulation of toxic proteins linked to Parkinson's disease

Researchers at Georgetown University Medical Center have used tiny doses of a leukemia drug to halt accumulation of toxic proteins linked to Parkinson's disease in the brains of mice. This finding provides the basis to plan a clinical trial in humans to study the effects.

Research on miRNAs offers new therapeutic potential to fight diseases

RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode proteins but act in gene regulation and, in the process, impact almost all biological processes - from development to physiology to stress response.

Living cells and cell fragments move in response to electric fields, scientists find

Like tiny crawling compass needles, whole living cells and cell fragments orient and move in response to electric fields - but in opposite directions, scientists at the University of California, Davis, have found. Their results, published April 8 in the journal Current Biology, could ultimately lead to new ways to heal wounds and deliver stem cell therapies.

Researchers discover protein that play role in spread of pancreatic cancer

Researchers at the University of North Carolina at Chapel Hill have discovered that a protein found in the cells surrounding pancreatic cancers play a role in the spread of the disease to other parts of the body.
