Anti-aging molecule discovered that extends lifespan – Earth.com

Researchers at the Buck Institute have made a significant breakthrough in the field of aging and disease with the discovery of a new drug-like molecule.

This molecule, known as MIC (Mitophagy-inducing compound), has been shown to extend lifespan and improve health in a variety of ways.

MIC operates by promoting healthy mitochondria through a process called mitophagy, which removes and recycles damaged mitochondria.

Mitochondria are crucial organelles in cells that produce energy, and their health is directly linked to overall cellular health and longevity.

The study demonstrated that this molecule extended the lifespan of C. elegans, a nematode worm frequently used in aging research.

MIC also improved mitochondrial function in mouse muscle cells and showed promise in ameliorating pathology in neurodegenerative disease models.

Mitochondrial dysfunction is known to play a role in various age-related diseases, including neurodegenerative disorders like Parkinsons and Alzheimers, cardiovascular diseases, metabolic disorders, muscle wasting, and cancer progression.

Despite the potential of treatments targeting mitochondrial dysfunction, none have been approved for human use to date.

The mitophagy-inducing compound is a coumarin, a type of naturally bioactive compound found in many plants and certain types of cinnamon.

Coumarins are known for their diverse health benefits, including anticoagulant, antibacterial, antifungal, antiviral, anticancer, antihyperglycemic properties, and neuroprotective effects.

The discovery of the effects of MIC originated from a study on Parkinsons disease. A team of experts including Dr. Julie Andersen and Dr. Shankar Chinta were examining known enhancers of mitophagy in a mouse model.

The mitophagy-inducing compound emerged as a significant find in their research. Instead of immediately testing MIC in mice, the researchers opted to study its impact on overall aging and its mechanism of action using the C. elegans model.

This approach led to the discovery that MIC belongs to a different class of molecules that enhance the expression of a key protein in autophagy and lysosomal functions (TFEB).

The study, led by Dr. Andersen and research scientist Dr. Manish Chamoli, revealed that MIC activates the transcription factor TFEB, a master regulator of genes involved in autophagy and lysosomal functions. Autophagy is an intracellular recycling process vital for cellular health.

The research findings are significant as they show MICs potential in not only extending lifespan but also preventing mitochondrial dysfunction in mammalian cells, offering new avenues for treating various age-related diseases.

Theres a bottleneck in efforts to develop potential therapeutics in the field of geroscience, and the bottleneck is that we dont have enough molecules in the pipeline, said study senior co-author Dr. Gordon Lithgow.

MIC is a great candidate to bring forward given its therapeutic effect across multiple models and the fact that it is a naturally occurring molecule.

Anti-aging strategies encompass a variety of practices and research areas focused on slowing down or reversing the aging process. Here are some key areas:

This includes a balanced diet rich in antioxidants, regular physical activity, adequate sleep, and stress management. Avoiding smoking and excessive alcohol consumption also plays a critical role.

Using sunscreen to protect the skin from UV damage, along with regular use of moisturizers and anti-aging products like retinoids and peptides, can help maintain skin health.

These include hormone replacement therapies, cosmetic procedures like Botox or fillers, and plastic surgery. These methods should be approached cautiously and under medical supervision.

Some people use supplements like omega-3 fatty acids, vitamin D, coenzyme Q10, and others believed to have anti-aging effects. However, their effectiveness can vary and should be used judiciously.

Areas like telomere therapy, stem cell research, and gene editing are being explored for potential anti-aging benefits. While promising, many of these are still in the experimental stages.

Maintaining mental health and active social life is essential. Activities that stimulate the mind, like puzzles, reading, and learning new skills, along with regular social interaction, can contribute to longevity and quality of life.

Regular visits to healthcare professionals for check-ups can help in early detection and management of age-related diseases.

Certain foods are known for their potential anti-aging benefits, mainly due to their high antioxidant content and other beneficial nutrients. Heres a list of some of these foods:

Incorporating these foods into a balanced diet can contribute to overall health and potentially slow some aspects of the aging process. Its also important to maintain a diverse diet and consult with a healthcare professional, especially when making significant dietary changes.

The research is published in the journal Nature Aging.
