Anti-ageing gene shown to rewind heart age by 10 years

Published

Breakthrough offers a potential target for patients with heart failure

Newswise — An anti-ageing gene discovered in a population of centenarians has been shown to rewind the heart’s biological age by 10 years. The breakthrough, published in Cardiovascular Research and led by scientists at the University of Bristol and the MultiMedica Group in Italy, offers a potential target for patients with heart failure.

Associated with exceptional longevity, carriers of healthy mutant genes, like those living in blue zones of the planet, often live to 100 years or more and remain in good health. These individuals are also less prone to cardiovascular complications. Scientists funded by the British Heart Foundation believe the gene helps to keep their hearts young by protecting them against diseases linked to ageing, such as heart failure.

In this new study, researchers demonstrate that one of these healthy mutant genes, previously proved particularly frequent in centenarians, can protect cells collected from patients with heart failure requiring cardiac transplantation.

The Bristol team, led by Professor Paolo Madeddu, has found that a single administration of the mutant anti-ageing gene halted the decay of heart function in middle-aged mice. Even more remarkably, when given to elderly mice, whose hearts exhibit the same alterations observed in elderly patients, the gene rewound the heart’s biological clock age by the human equivalent of more than ten years.

Professor Madeddu, Professor of Experimental Cardiovascular Medicine from Bristol Heart Institute at the University of Bristol and one of the study’s authors, explained: “The heart and blood vessel function is put at stake as we age. However, the rate at which these harmful changes occur is different among people. Smoking, alcohol, and sedentary life make the ageing clock faster. Whereas eating well and exercising delay the heart’s ageing clock.

“In addition, having good genes inherited from parents can help to stay young and healthy. Genes are sequences of letters that encode proteins. By chance, some of these letters can mutate. Most of these mutations are insignificant; in a few cases, however, the mutation can make the gene function worse or better, like for the mutant anti-ageing gene we have studied here on human cells and older mice.”

The three-year study was also performed in test tube human cardiac cells in Italy. Researchers from the MultiMedica Group in Milan led by Professor Annibale Puca, administered the gene in heart cells from elderly patients with severe heart problems, including transplantation, and then compared their function with those of healthy individuals.

Monica Cattaneo, a researcher of the MultiMedica Group in Milan, Italy, and first author of the work said: “The cells of the elderly patients, in particular those that support the construction of new blood vessels, called ‘pericytes’, were found to be less performing and more aged. By adding the longevity gene/protein to the test tube, we observed a process of cardiac rejuvenation: the cardiac cells of elderly heart failure patients have resumed functioning properly, proving to be more efficient in building new blood vessels.”

Centenarians pass their healthy genes to their offspring. The study demonstrates for the first time that a healthy gene found in centenarians could be transferred to unrelated people to protect their hearts. Other mutations might be found in the future with similar or even superior curative potential than the one investigated by this research. Professor Madeddu and Professor Annibale Puca of the MultiMedica Group in Milan believe this study may fuel a new wave of treatments inspired by the genetics of centenarians. 

Professor Madeddu added: “Our findings confirm the healthy mutant gene can reverse the decline of heart performance in older people. We are now interested in determining if giving the protein instead of the gene can also work. Gene therapy is widely used to treat diseases caused by bad genes. However, a treatment based on a protein is safer and more viable than gene therapy.

“We have received funding from the Medical Research Council to test healthy gene therapy in Progeria. This genetic disease, also known as Hutchinson-Gilford syndrome, causes early aging damage to children’s hearts and blood vessels. We have also been funded by the British Heart Foundation and Diabetes UK to test the protein in older and diabetic mice, respectively.”

Annibale Puca, Head of the laboratory at the IRCCS MultiMedica and Professor at the University of Salerno, added: “Gene therapy with the healthy gene in mouse models of disease has already been shown to prevent the onset of atherosclerosis, vascular ageing, and diabetic complications, and to rejuvenate the immune system.

“We have a new confirmation and enlargement of the therapeutic potential of the gene/protein. We hope to test its effectiveness soon in clinical trials on patients with heart failure.”

Professor James Leiper, Associate Medical Director at the British Heart Foundation, which funded the research, said: “We all want to know the secrets of ageing and how we might slow down age-related disease. Our heart function declines with age but this research has extraordinarily revealed that a variant of a gene that is commonly found in long-lived people can halt and even reverse ageing of the heart in mice.

“This is still early-stage research, but could one day provide a revolutionary way to treat people with heart failure and even stop the debilitating condition from developing in the first place.”

The study is funded by the British Heart Foundation and the Italian Ministry of Health.

5 strategies to combat stressful triggers

(Family Features) Stress, the physical or mental response to external causes like overwhelming work assignments or difficult life moments, can add unnecessary pressure to your day to day. While everyone feels stress from time to time, when left untreated or unrecognized, it can begin to wreak havoc in the form of anxiety.

In honor of National Stress Awareness Month, consider these strategies to combat stress from the National Institutes of Mental Health.

Learn Your Triggers
Different events and situations cause stress for different people. Knowing what triggers your stress to kick in – mounds of office paperwork, important financial decisions or hectic mornings, for example – can help you plan and prepare for stress-inducing moments.

Exercise and Eat Right
Maintaining physical health can be beneficial for mental health, too. Find time to do exercises you enjoy like walking, jogging, yoga or playing a sport. Identifying activities that bring you joy can make it easier to fit 30-60-minute workouts into your schedule without adding even more stress. Complement your workout routine with nutritional meals that help you stay on track with your fitness goals.

Practice Relaxation
Whether you find inner peace through journaling, breathing exercises, reading or some other form of slowing down, find what works for you and prioritize fitting it into your daily schedule. Relaxing activities help you slow down the pace of life, providing a chance to reset by doing something you enjoy.

Get Enough Sleep
A lack of quality sleep can add to stress. Creating a bedtime routine can increase your sleep habits and help you achieve the expert-recommended 7-9 hours per night. Put away electronics, which can interfere with your ability to calm your mind, and find an activity that puts you at ease like reading a book or listening to relaxing music. Ensure your bedroom is optimized for comfort by making it cool, dark and quiet.

Create a Network of Support
Everyone experiences stress. Reach out to family members and close friends you can lean on in stressful and frustrating moments. Share your feelings and encourage others to do the same, which can increase trust and help everyone in your circle cope in a positive way.

Managing Asthma Triggers

Published

on

(Family Features) For those with asthma, understanding what can trigger symptoms is a part of getting the condition under control. Some of the same things that cause allergies can worsen symptoms, but not every allergen is a trigger for everyone with asthma. The places where you live, learn, work and play can expose you to common asthma triggers like pet dander, dust mites, pests like rodents and cockroaches, mold, cigarette smoke, pollen, air pollution and more. Managing triggers is just one part of controlling asthma, however. Work with your health care provider to make an asthma action plan and keep track of your symptoms and where you are when they occur.

What are the Risks of Eating Seafood?

Although seafood is a nutritious option to fulfill dietary nutrient gaps, there are some environmental and health concerns related to its consumption.

Seafood may contain toxins, viruses, parasites, and bacteria that can be harmful if consumed. To avoid getting sick, it is essential to cook fish and shellfish thoroughly. As per the USDA guidelines, most seafood should be cooked to an internal temperature of 145 degrees Fahrenheit.

Contaminants, including Mercury and Others

Overconsumption of certain seafood varieties can have negative health effects due to the presence of contaminants. For instance, specific fish species contain high levels of mercury, a heavy metal that can be easily absorbed by the body. Mercury accumulation is more common in larger fish, as they consume smaller fish that have ingested mercury-rich plankton. Consequently, larger and older fish are typically the most mercury-contaminated.

Regularly consuming foods high in mercury can result in mercury accumulation in the body, leading to health problems like high blood pressure, heart attack, and developmental delay in offspring. Mercury is toxic and can have detrimental effects on the body.

Mercury can have a greater impact on certain groups, such as pregnant and breastfeeding women, as well as children, who are more susceptible to its effects.

To reduce the amount of mercury in your diet, avoid consuming seafood like shark, certain types of tuna, swordfish, tilefish, and king mackerel as they have high mercury levels. Instead, opt for low-mercury options such as trout, cod, oysters, clams, herring, salmon, and sardines.
