Researchers at the University of Dundee have made a discovery they believe has the potential to put the brakes on the ‘runaway train’ that is Parkinson’s disease.

The team, based at the Medical Research Council Protein Phosphorylation and Ubiquitylation Unit (MRC-PPU) in the School of Life Sciences, have discovered a new enzyme that inhibits the LRRK2 pathway. Mutations of the LRRK2 gene are the most common cause of genetic Parkinson’s.

Enzymes are molecular machines that regulate the biological processes required to maintain healthy functioning life. They can also be targeted by drugs to increase or decrease the level of certain activity –in this instance the LRRK2 pathway.

Unlike chemotherapy or radiation, which attack cancer directly, CAR-T engineers patients’ immune cells so they can do it themselves. T-cells are removed from the blood and given new genes that produce receptors that let the T-cells recognize and bind to leukemia cells with a specific protein, CD19.

The genetically modified T-cells are then multiplied in the lab and infused back into the patient, where they ideally multiply even further and begin to target and kill cancer cells with CD19.

A pair of new studies report “impressive” benefits from a drug therapy for cystic fibrosis, a deadly and devastating disease that affects tens of thousands of people worldwide, the director of the National Institutes of Health wrote in an editorial published in The New England Journal of Medicine on Thursday.

“These findings indicate that it may soon be possible to offer safe and effective molecularly targeted therapies to 90 percent of persons with cystic fibrosis,” wrote the director, Dr. Francis S. Collins, who led the team that in 1989 identified the gene that causes the genetic disease affecting the lungs and digestive system.

“This should be a cause for major celebration,” he wrote in the Thursday editorial.

Humans’ guts are a dangerous place.

Bacteria living in people’s intestines pump out toxins to deter microbial intruders. But each person’s gut comes with its own set of toxins—an individualized “passcode” microbes must solve to survive, scientists report October 30, 2019, in the journal Nature.

The findings suggest that there’s not a one-size-fits-all approach to probiotics or live biotherapeutics, the microbial supplements that promote the growth of healthy bacteria, says study coauthor Joseph Mougous, a Howard Hughes Medical Institute (HHMI) Investigator at the University of Washington (UW). His team’s work is an early step toward figuring out how scientists might instead tailor beneficial microbes to different people.

At the University of Copenhagen, researchers have discovered how some types of proteins stabilize damaged DNA and thereby preserve DNA function and integrity. This new finding also explains why people with inborn or acquired defects in certain proteins cannot keep their DNA stable and develop diseases such as cancer.

Every day, the body’s cells divide millions of times, and the maintenance of their identity requires that a mother cell passes complete genetic information to daughter cells without mistakes.

This is not a small task because our DNA is constantly under attack, both from the environment but also from the cell’s own metabolic activities. As a result, DNA strands can be broken at least once during each cell division cycle and this frequency can increase by certain lifestyles, such as smoking, or in individuals who are born with defects in DNA repair.

A chance finding ten years ago led to the creation by researchers of the Spanish National Cancer Research Centre (CNIO) of the first mice born with much longer telomeres than normal in their species. Given the relationship between telomeres and ageing – telomeres shorten throughout life, so older organisms have shorter telomeres -, scientists launched a study generating mice in which 100% of their cells had hyper-long telomeres. The findings are published in Nature Communications and show only positive consequences: the animals with hyper-long live longer in better health, free from cancer and obesity. The most relevant thing for the authors is the fact that longevity has been significantly increased for the first time ever without any genetic modification.

“This finding supports the idea that, when it comes to determining longevity, genes are not the only thing to consider”, indicates Maria Blasco, Head of the CNIO Telomeres and Telomerase Group and intellectual author of the paper. “There is margin for extending life without altering the genes”.

Telomeres form the end of chromosomes, in the nucleus of each cell in the body. Their function is to protect the integrity of the genetic information in DNA. Whenever the cells divide the telomeres, they are shortened a little, so one of the main characteristics of ageing is the accumulation of short telomeres in cells. “Telomere shortening is considered to be one of the primary causes of ageing, given that short telomeres cause ageing of the organism and reduce longevity”, as the paper published in Nature Communications explains.
