Gene APOE4 causes Alzheimers disease in humans and a fix has been created

Researchers have found differences in how Alzheimers disease originates and develops in mice and humans. They determined which gene causes Alzheimers in humans and have developed a fix for it. Dementia and Alzheimer’s disease aren’t the same. Dementia is an overall term used to describe symptoms that impact memory, performance of daily activities, and communication …

Gene therapy for common blood disorders

In a landmark study that could lead to new therapies for sickle cell anaemia and other blood disorders, UNSW Sydney-led researchers have used CRISPR gene editing to introduce beneficial natural mutations into blood cells to boost their production of foetal haemoglobin. The research solves a 50-year-old mystery about how these mutations – which are naturally …

China leads world with 8 CRISPR trials to treat cancer and CRISPR medicine is a national priority

China has at least eight CRISPR gene therapy clinical trials to treat various forms of cancer. CRISPR is being tested as a treatment for cancers of the lung, bladder, cervix and prostate. Clinicaltrials.gov lists all of the clinical trials in the world. Only one CRISPR cancer study has been approved in the United States, and …

Beyond Crispr -Cas9 Gene editing

Crispr/Cas9 is a riboprotein complex composed of a short strand of RNA and an efficient DNA-cutting enzyme. Crispr/Cas9 sometimes cuts in the wrong places. And it has no off-switch. Epigenetic Editing Other proteins—like ones that activate gene expression—can be combined with a crippled Cas9, letting them toggle genes on and off (sometimes with light or …

CRISPR extends lifespan of Lou Gehrigs disease mice by 25%

University of California, Berkeley scientists have for the first time used CRISPR-Cas9 gene editing to disable a defective gene that causes amyotrophic lateral sclerosis, or Lou Gehrig’s disease, in mice, extending their lifespan by 25 percent. The therapy delayed the onset of the muscle wasting that characterizes the disease, which results in progressive weakness and …

THOR gene could be critical to curing cancer

Researchers have identified and characterized a new type of RNA protein called THOR that plays a role in cancer development — and could serve as a target for drug development. Researchers at the University of Michigan Comprehensive Cancer Center uncovered a novel gene they named THOR while investigating previously unexplored regions of the human genome …

Supercentenarian may have genes that protect against bad effects of aging

James Clement has collected blood, skin or saliva from supercentenarians in 14 states and seven countries over a six-year period. Lifestyle and luck, it seems, still factor heavily into why people live into their 90s and 100s. However, supercentenarians are more uniformly healthy than centenarians in their final months and years. Rather than having won …
