Rare breeds of chickens could soon come from entirely different types of hens. The University of Edinburgh’s Roslin Institute with help from US biotechnology company Recombinetics used gene editing techniques to create surrogate hens that grow up to produce eggs with all the genetic information of different breeds.
The team used a gene editing tool called TALEN (for transcription activator-like effector nucleases), which is similar to the more widely publicized CRISPR/Cas9, to delete part of a chicken gene called DDX4 that is related to fertility. Hens with this modification did not produce eggs but were healthy in all other ways.
Our society has never aged more rapidly – one of the most visible symptoms of the changing demographics is the exponential increase in the incidence of age-related diseases, including cancer, cardiovascular diseases and osteoarthritis. Not only does aging have a negative effect on the quality of life among the elderly but it also causes a significant financial strain on both private and public sectors. As the proportion of older people is increasing so is health care spending. According to a WHO analysis, the annual number of new cancer cases is projected to rise to 17 million by 2020, and reach 27 million by 2030. Similar trends are clearly visible in other age-related diseases such as cardiovascular disease. Few effective treatments addressing these challenges are currently available and most of them focus on a single disease rather than adopting a more holistic approach to aging.
Recently a new approach which has the potential of significantly alleviating these problems has been validated by a number of in vivo and in vitro studies. It has been demonstrated that senescent cells (cells which have ceased to replicate due to stress or replicative capacity exhaustion) are linked to many age-related diseases. Furthermore, removing senescent cells from mice has been recently shown to drastically increase mouse healthspan (a period of life free of serious diseases).
Here at CellAge we are working hard to help translate these findings into humans!
CellAge, together with a leading synthetic biology partner, Synpromics, is going to develop synthetic promoters which are specific to senescent cells (SeneSENSE), as promoters that are currently being used to track senescent cells are simply not good enough to be used in therapies. The most prominently used p16 gene promoter has a number of limitations, for example. As our primary mission is to expand the interface between synthetic biology and aging research as well as drive translational research forward, we will offer senescence reporter assay to academics for free. We predict that in the very near future this assay will be also used as a quality control step in the cell therapy manufacturing process to make cell therapies safer!
Husar, a 38-year-old telecom salesman, had spent most of his life eating the sort of Eastern European fare typical of his native Ukraine: lots of meat, potatoes, salt and saturated fats. DNA Lifestyle Coach suggested his body might appreciate a more Mediterranean diet instead.
Recently, Vitaliy Husar received results from a DNA screening that changed his life. It wasn’t a gene that suggested a high likelihood of cancer or a shocking revelation about his family tree. It was his diet. It was all wrong.
But between the jokes is the data. Bill and Melinda Gates sum up what has been achieved with their combined billions over the past decade in a series of big numbers, and end with the hope of reaching the magic zero – no more disease.
In letter to philanthropic partner Warren Buffett, the Gates define achievements from vaccines to lives saved – while still pushing for gains in infant mortality.
Team OB just won the Robotics for Good Award in Dubai. Over 1,600 technologies for good applied and after competing against the top 10 best assistive technologies the judges chose our bionic hands! Now we have the funding to push our hands through the final stages of medical testing and finally get them to everyone who needs one.
Smartphones are revolutionizing the diagnosis and treatment of illnesses, thanks to add-ons and apps that make their ubiquitous small screens into medical devices, researchers say.
“If you look at the camera, the flash, the microphone… they all are getting better and better,” said Shwetak Patel, engineering professor at the University of Washington.
“In fact the capabilities on those phones are as great as some of the specialized devices,” he told the American Association for the Advancement of Science (AAAS) annual meeting this week.
Church mentioned human trials in 2 years a few months ago. this is the first I have seen him say that in 10 years the reversal of aging will be a reality. That’ll make me 55. Hurry.
While discussing creating a hybrid elephant — wooly mammoth using CRISPR genome editing, Harvard’s George Church predicted that reversal of aging will be a reality within ten years.
