Gene Transfer Leads to Longer Life and Healthspan

Posted by in categories: biotech/medical, genetics, life extension

The naked mole rat won’t win any beauty contests, but it could possibly win in the talent category. Its superpower: fighting the aging process to live several times longer than other animals its size, in a state of youthful vigor.

It’s believed that naked mole rats experience all the normal processes of wear and tear over their lifespan, but that they’re exceptionally good at repairing the damage from oxygen free radicals and the DNA errors that accumulate over time. Even though they possess genes that make them vulnerable to cancer, they rarely develop the disease, or any other age-related disease, for that matter. Naked mole rats are known to live for over 40 years without any signs of aging, whereas mice live on average about two years and are highly prone to cancer.

Now, these remarkable animals may be able to share their superpower with other species. In August, a study provided what may be the first proof-of-principle that genetic material transferred from one species can increase both longevity and healthspan in a recipient animal.

Extracellular Matrix-Based Biomaterials for Cardiovascular Tissue Engineering

Posted by in categories: bioengineering, biotech/medical, chemistry, life extension

Regenerative medicine and tissue engineering strategies have made remarkable progress in remodeling, replacing, and regenerating damaged cardiovascular tissues. The design of three-dimensional (3D) scaffolds with appropriate biochemical and mechanical characteristics is critical for engineering tissue-engineered replacements. The extracellular matrix (ECM) is a dynamic scaffolding structure characterized by tissue-specific biochemical, biophysical, and mechanical properties that modulates cellular behavior and activates highly regulated signaling pathways. In light of technological advancements, biomaterial-based scaffolds have been developed that better mimic physiological ECM properties, provide signaling cues that modulate cellular behavior, and form functional tissues and organs.

How ultra-processed food affects mental health

Posted by in categories: biotech/medical, life extension, neuroscience

Ultra-processed foods can have a negative effect on mental health, and this is especially true for younger people, who consume more of these foods than older people.

Over time, there has been increasing evidence that those whose diet includes large quantities of ultra-processed foods are more likely to develop physical health issues.

These issues can include obesity, type 2 diabetes, cardiovascular disease, and even more rapid aging. This is supported by wide research, including a paper by the IRCCS Neuromed Mediterranean Neurological Institute in Italy, involving about 23,000 citizens from the Molise region.

Genetic Factors that Could Extend the Life of Golden Retrievers

Posted by in categories: biotech/medical, genetics, life extension

One of the most popular dog breeds is the Golden Retriever. Unfortunately, these dogs are also at high risk for developing cancer. New research has investigated genetic factors that may be able to extend the lives of these beloved dogs. This work focused on longevity genes instead of those that have been associated with cancer, and led to the identification of gene variants that could extend the dogs’ lifespan by as much as two years. The findings have been reported in GeroScience.

While most golden retrievers are predisposed to cancer, some of these dogs can live to be as old as 15 or 16 years. So the researchers thought that there might be genetic factors that were mitigating the effect of the cancer-related genes, noted co-corresponding study author Robert Rebhun, Maxine Adler Endowed Chair in oncology at the UC Davis School of Veterinary Medicine. The gene that had this effect was HER4.

TruDiagnostic and Harvard announce new multi omic informed biological aging clock

Posted by in categories: biotech/medical, genetics, life extension

A study published today by scientists from Harvard University and epigenetic research company TruDiagnostic has shed light on the reasons why our bodies are aging on a cellular level, laying the foundations for medical based treatment options to reduce the risk of age-related death and disease in highly targeted ways.

Longevity. Technology: Age is the number one risk factor for most chronic diseases and death across the world. Epigenetics (or the way our genes are put to use throughout our bodies) has emerged as a crucial method of evaluating health, and while previous DNA methylation clocks could determine how advanced one’s body has aged, they have not yet been able to provide information to the reasons why someone might have accelerated or decelerated aging outcomes.

“In our research, we set out to create the best method to quantify the biological aging process. However, aging is extremely complex,” explains Harvard Medical School Associate Professor Dr Jessica Lasky-Su. “To solve this issue of complexity, our approach was to gather data across multiple sources of information. We chose to do this by building one of the most robust aging datasets in the world by quantifying patients’ proteomics, metabolomics, clinical histories and DNA methylation.”
