Scientists identify a new way to increase enzymes’ life span

Like the parts of a car that make it go, enzymes in living cells can eventually wear out or break over time, and researchers at The University of Western Australia have now discovered what determines an enzyme’s working life and what needs to be done to keep it working longer.

Researchers identify chemicals that keep HIV virus in dormant state

When the human immunodeficiency virus infects cells, it can either exploit the cells to start making more copies of itself or remain dormant--a phenomenon called latency.

Acute exposure of lung tissue to vape aerosol has lesser impact on gene expression than cigarette smoke

A new peer-reviewed study published in the journal Toxicological Research & Application shows acute exposure of a 3D human bronchial tissue model to e-cigarette aerosol has minimal impact on gene expression compared to smoke from combustible cigarettes.

Study maps structure and mechanism of a membrane enzyme that plays role in inflammation, cancer

Most drugs operate via the membranes that surround the body's cells. A study by researchers at Karolinska Institutet in Sweden has now mapped the structure and mechanism of MGST2, a membrane enzyme that, amongst other things, plays a part in chronic inflammation and cancer.

Weight loss induced by diet and bariatric surgery has different impact on mitochondria in fat tissue

Dieting impairs the energy-producing machinery of fat tissue, potentially resulting in weight regain. In contrast, as indicated by a recently completed European study coordinated by the University of Helsinki, weight loss surgery gives a boost to mitochondria, improving the gene expression of these cellular engines.
