Dr. David Sinclair on Informational Theory of Aging, Nicotinamide Mononucleotide, Resveratrol & More

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

David A. Sinclair, PhD, is a professor in the Department of Genetics at Harvard Medical School and co-director of the Paul F. Glenn Center for the Biological Mechanisms of Aging.
Dr. Sinclair’s work focuses on understanding the mechanisms that drive human aging and identifying ways to slow or reverse aging’s effects. In particular, he has examined the role of sirtuins in disease and aging, with special emphasis on how sirtuin activity is modulated by compounds produced by the body as well as those consumed in the diet, such as resveratrol. His work has implications for human metabolism, mitochondrial and neurological health, and cancer.

First use of CRISPR against cancer in patients clears safety hurdles

Posted by in categories: bioengineering, biotech/medical, genetics

The first attempt in the United States to use a gene editing tool called CRISPR against cancer seems safe in the three patients who have had it so far, but it’s too soon to know if it will improve survival, doctors reported Wednesday.

The doctors were able to take immune system cells from the patients’ blood and alter them genetically to help them recognize and fight cancer, with minimal and manageable side effects. The treatment deletes three genes that might have been hindering these cells’ ability to attack the disease, and adds a new, fourth feature to help them do the job.

“It’s the most complicated genetic, cellular engineering that’s been attempted so far,” said the study leader, Dr. Edward Stadtmauer of the University of Pennsylvania in Philadelphia. “This is proof that we can safely do gene editing of these cells.”

All children to receive whole genome sequencing at birth, under ambitions laid out

Posted by in categories: biotech/medical, genetics, health

All children will be able to receive whole genome sequencing at birth, under ambitions laid out by the Health Secretary.

Matt Hancock said that in future, the tests would be routinely offered, alongside standard checks on newborns, in order to map out the risk of genetic diseases, and offer “predictive, personalised” care.

Ministers have already promised that such tests will be offered to all children diagnosed with cancer by the end of this year.

Scientists extend mice lifespan 12%

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

Scientists successfully extended the average lifespan of mice by breeding them using embryonic stem cells with extra-long telomeres. The findings are significant because the researchers managed to extend lifespan without genetic modification, and they also shed light on the aging process and techniques that might someday slow it.

The study — published October 17 in Nature Communicationsfocuses on telomeres, which are stretches of DNA found at the end of chromosomes.

Because telomeres protect the genetic material inside chromosomes, they’ve been likened to the plastic tips on the ends of shoelaces. But telomeres have also been compared to bomb fuses, or “molecular clocks,” because they become shorter each time a cell divides, eventually shrinking so much that the cell dies or stops dividing. This shortening of our telomeres is associated with aging, cancer, and death.

How we Benefit from Getting our Genomes Sequenced

Posted by in categories: biotech/medical, finance, food, genetics, habitats, health, internet, mobile phones

When the first smartphones arrived, few people understood how they would change our reality. Today, our internet-connected mobile device maps our travel, manages our finances, delivers our dinner, and connects us to every corner of human knowledge. In less than a generation, it has become almost an extension of our central nervous system — so indispensable that we can’t imagine leaving home without it to guide us.

We are about to embark on another journey even more important to every individual and to human society. We are entering the age of genomics, an amazing future that will dramatically improve the health outcomes of people across the planet. Soon, we won’t be able to imagine a time when we left home without knowledge of our genome to guide us.

Discovery may help derail Parkinson’s ‘runaway train’

Posted by in categories: biotech/medical, genetics, nanotechnology

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 . Mutations of the LRRK2 gene are the most common cause of genetic Parkinson’s.

Enzymes are molecular machines that regulate the 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.

Science author digs into the story about a revolutionary cancer treatment used in immunotherapy

Posted by in categories: biotech/medical, genetics, science

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.

David Pearce — The Anatomy of Happiness

“While researching epilepsy, neuroscientist Itzhak Fried stumbled on a ‘mirth’ center in the brain — given this, what ought we be doing to combat extreme suffering and promote wellbeing?”
