Working with human breast and lung cells, Johns Hopkins Medicine scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many times, a hallmark of cancer cells.

The findings, published May 3 in Science, reveal what goes wrong when a group of molecules and enzymes trigger and regulate what's known as the "cell cycle," the repetitive process of making new cells out of the cells' genetic material.

Many bacteria produce substances to gain an advantage over competitors in their highly competitive natural environment. Researchers at the University Hospital Bonn (UKB), the University of Bonn and the German Center for Infection Research (DZIF) have discovered a new so-called lantibiotic, namely epilancin A37. It is produced by staphylococci that colonize the skin and acts specifically against their main competitors there, the corynebacteria.

Researchers at UNC Lineberger Comprehensive Cancer Center, after decades of research efforts, have developed a mouse model of Kaposi sarcoma that could be key to the development of new drugs to treat the disease. Kaposi sarcoma is a cancer that is the most common cancer in people living with HIV.

The findings appeared in Cell Host & Microbe.

A healthy lifestyle may offset the effects of life-shortening genes by more than 60%, suggests an analysis of the findings from several large long term studies, published online in the journal BMJ Evidence Based Medicine.

While genes and lifestyle seem to have an additive effect on a person's lifespan, an unhealthy lifestyle is independently linked to a 78% heightened risk of dying before one’s time, regardless of genetic predisposition, the research indicates.

In a landmark study, an international consortium led by researchers at Children's Hospital of Philadelphia (CHOP) published the final results of a key clinical trial of the gene therapy CASGEVY (exagamglogene autotemcel) for the treatment of sickle cell disease in patients 12 years and older with recurrent vaso-occlusive crises (VOCs). The study found that 96.7% of patients in the study did not have any vaso-occlusive crises (VOCs) - a blockage that results in lack of oxygen and painful episodes - for at least one year, and 100% were able to remain hospitalization-free for the same length of time.

Researchers have described the optimal timing for COVID-19 patients to take the antiviral, Paxlovid, to get the most benefit from the treatment, according to a study published April 16 in eLife.

The findings suggest that taking Paxlovid three to five days after COVID-19 symptoms emerge may maximise the drug's ability to reduce viral loads, minimise viral spread and reduce viral rebound.

Cancer is the monster of our society. Last year alone, more than 600,000 people in the United States died from cancer, according to the American Cancer Society. The relentless pursuit of understanding this complex disease has shaped medical progress on developing treatment procedures that are less invasive while still highly effective.

Immunotherapy is on the rise as a possible solution. Immunotherapy involves harnessing the power of the body's immune system to fight against cancer cells.
