University of Nebraska Medical Center researchers reveal elusive inner workings of antioxidant enzyme with therapeutic potential

The enzyme manganese superoxide dismutase helps maintain human health by keeping the amount of reactive oxygen molecules in cells under control. Using neutron scattering at ORNL, researchers obtained a complete atomic portrait of the enzyme, revealing key information about its catalytic mechanism.

Amoeba Biology Reveals Potential Treatment Target for Lung Disease

In a series of experiments that began with amoebas — single-celled organisms that extend podlike appendages to move around — Johns Hopkins Medicine scientists say they have identified a genetic pathway that could be activated to help sweep out mucus from the lungs of people with chronic obstructive pulmonary disease a widespread lung ailment.

UCLA scientists develop high-throughput mitochondria transfer device

Scientists from the UCLA Jonsson Comprehensive Cancer Center have developed a simple, high-throughput method for transferring isolated mitochondria and their associated mitochondrial DNA into mammalian cells. This approach enables researchers to tailor a key genetic component of cells, to study and potentially treat debilitating diseases such as cancer, diabetes and metabolic disorders.

NEI researchers link age-related DNA modifications to susceptibility to eye disease

National Eye Institute (NEI) researchers profiling epigenomic changes in light-sensing mouse photoreceptors have a clearer picture of how age-related eye diseases may be linked to age-related changes in the regulation of gene expression. The findings, published online April 21 in Cell Reports, suggest that the epigenome could be targeted as a therapeutic strategy to prevent leading causes of vision loss, such as age-related macular degeneration (AMD).

Study provides new understanding of mitochondria genome with potential for new avenues of treatment for multiple cancers

A study led by The University of Texas MD Anderson Cancer Center furthered understanding about mitochondria, the cell components known as the “powerhouse of the cell.” Knowing more about the genome is crucial given that mitochondria play important roles in tumorigenesis.

Subtle Mitochondrial DNA Mutations Alter Expression of Nuclear Genes, with Profound Clinical Effects

Subtle changes in the DNA of mitochondria, the tiny power plants in cells, can have profound consequences for a patient’s health. Research on biological mechanisms suggests that relatively minor changes in mitochondrial energy flow and metabolism could offer significant future benefits to patients with complex diseases.
