New study on transmitophagy process may help treat diverse disorders

It's broadly assumed that cells degrade and recycle their own old or damaged organelles, but researchers at University of California, San Diego School of Medicine, The Johns Hopkins University School of Medicine and Kennedy Krieger Institute have discovered that some neurons transfer unwanted mitochondria - the tiny power plants inside cells - to supporting glial cells called astrocytes for disposal.

New dual-pronged approach for treating Niemann-Pick type C disease

By studying nerve and liver cells grown from patient-derived induced pluripotent stem cells (iPSCs), Whitehead Institute researchers have identified a potential dual-pronged approach to treating Niemann-Pick type C (NPC) disease, a rare but devastating genetic disorder.

SapC-DOPS technology: New way to image glioblastoma multiforme tumors

Just because you can't see something doesn't mean it's not there. Brain tumors are an extremely serious example of this and are not only difficult to treat-both adult and pediatric patients have a five-year survival rate of only 30 percent-but also have even been difficult to image, which could provide important information for deciding next steps in the treatment process.

Salk scientists explore earliest detectable changes in the brain that lead to schizophrenia

Using new stem cell technology, scientists at the Salk Institute have shown that neurons generated from the skin cells of people with schizophrenia behave strangely in early developmental stages, providing a hint as to ways to detect and potentially treat the disease early.

Children with autism experience deficits in immune cell that protects against infection

Children with autism experience deficits in a type of immune cell that protects the body from infection. Called granulocytes, the cells exhibit one-third the capacity to fight infection and protect the body from invasion compared with the same cells in children who are developing normally.

Noval neuroimaging technique enables detailed insights into mitochondria

Reactive oxygen species are important intracellular signaling molecules, but their mode of action is complex: In low concentrations they regulate key aspects of cellular function and behavior, while at high concentrations they can cause "oxidative stress", which damages organelles, membranes and DNA.

Researchers examine link between alcoholism and loss of muscle strength

Muscle weakness is a common symptom of both long-time alcoholics and patients with mitochondrial disease. Now researchers have found a common link: mitochondria that are unable to self-repair.

Highly advanced imaging method helps to monitor rapid changes in glutathione redox potentials in live cells

In the April issue of Experimental Biology and Medicine a multidisciplinary research team led by Drs. Rex Gaskins and Paul Kenis in the Institute of Genomic Biology (IGB) on the campus of the University of Illinois Urbana-Champaign describe their recent work on subcellular redox homeostasis.

B1/Cdk1 protein which plays key role in cell division also boosts power of mitochondrial activity

An international team led by researchers at UC Davis has shown that the cyclin B1/Cdk1 protein complex, which plays a key role in cell division, also boosts the mitochondrial activity to power that process.

Researchers identify mechanism that explains reason for persistence of hepatitis C virus

Researchers at the University of California, San Diego School of Medicine have identified a mechanism that explains why people with the hepatitis C virus get liver disease and why the virus is able to persist in the body for so long.

Researchers reveal how cells respond to mechanical manipulation

The push and pull of physical force can cause profound changes in the behavior of a cell. Two studies from researchers working at the UNC Lineberger Comprehensive Cancer Center reveal how cells respond to mechanical manipulation

Inhibiting cancer-promoting prolactin causes unconventional cell death in preclinical research

Under stress from chemotherapy or radiation, some cancer cells dodge death by consuming a bit of themselves, allowing them to essentially sleep through treatment and later awaken as tougher, resistant disease.

Researchers find potential way to ease physical damage of numerous genetic disorders

Duke Medicine researchers studying tiny, antennae-like structures called cilia have found a potential way to ease some of the physical damage of numerous genetic disorders that result when these essential cellular components are defective.

UT Southwestern professor honored with 2014 Norman Hackerman Award in Chemical Research

Dr. Benjamin P. Tu, associate professor of biochemistry at UT Southwestern Medical Center, was honored today with the 2014 Norman Hackerman Award in Chemical Research. Dr. Tu was recognized for innovative studies of once-unappreciated molecules that may someday improve treatments for cancer or conditions associated with aging.

Researchers examine how diabetes drug can benefit cancer patients

For several years, a class of anti-diabetic drugs known as biguanides, has been associated with anti-cancer properties. A number of retrospective studies have shown that the widely used diabetes drug metformin can benefit some cancer patients.

Levels of bisphenol A in men's urine could be marker of prostate cancer

Findings by Cincinnati Cancer Center researchers show that levels of bisphenol A (BPA) in men's urine could be a marker of prostate cancer and that low levels of BPA exposure can cause cellular changes in both non-malignant and malignant prostate cells.

Scientists carry out first studies of living biological cells using high-energy X-rays

G-ttingen-based scientists working at DESY's PETRA III research light source have carried out the first studies of living biological cells using high-energy X-rays. The new method shows clear differences in the internal cellular structure between living and dead, chemically fixed cells that are often analysed.

Researchers create new probe that freezes cells to "see" at greater detail without damaging

It's an odd twist. For scientists to determine if a cell is functioning properly, they must destroy it. This is what happens in X-ray fluorescence microscopy when biological specimens are exposed to ionizing radiation, which provides images with a level of detail that conventional microscopes just can't match.

Engineers place tiny synthetic motors inside live human cells

For the first time, a team of chemists and engineers at Penn State University have placed tiny synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically. It's not exactly "Fantastic Voyage," but it's close. The nanomotors, which are rocket-shaped metal particles, move around inside the cells, spinning and battering against the cell membrane.
