    American regulators granted approval on Wednesday to a gene-altering treatment for patients suffering from lymphoma, the second-ever approval for a gene therapy procedure and one that could revolutionize how we fight cancer. The drug, named Yescarta, was developed by Israeli-founded Kite Pharma and it is expected to cost some $373,000, likely generating hundreds of millions of dollars in sales. Kite was purchased by Gilead Sciences in August to the tune of $11.9 billion, and today’s breakthrough may have helped with the sale. The price of Yescarta is set below that of comparable treatments, according to Reuters, as Novartis AG’s gene...

    Researchers at UNSW Australia have for the first time used electrical pulses delivered from a cochlear implant to deliver gene therapy, thereby successfully regrowing auditory nerves. The research also heralds a possible new way of treating a range of neurological disorders, including Parkinson's disease, and psychiatric conditions such as depression through this novel way of delivering gene therapy. The research is published today (Thursday 24 April) in the journal Science Translational Medicine. "People with cochlear implants do well with understanding speech, but their perception of pitch can be poor, so they often miss out on the joy of music," says...

    From millions of random mutations, scientists identify a virus that could make gene therapy for inherited retinal diseases safer and more effective.Special delivery: Eight weeks after the new virus was injected into the eye of a monkey, the activity of a fluorescent gene it delivered can be seen in spots across the retina. A new delivery mechanism shuttles gene therapy deep into the eye’s retina to repair damaged light-sensing cells without requiring a surgeon to put a needle through this delicate tissue. The approach could make it substantially easier to treat inherited forms of eye disease with this approach.Although still...

    WITHIN just eight days of starting a novel gene therapy, David Aponte's "incurable" leukaemia had vanished. For four other patients, the same happened within eight weeks, although one later died from a blood clot unrelated to the treatment, and another after relapsing. The cured trio, who were all previously diagnosed with usually fatal relapses of acute lymphoblastic leukaemia, have now been in remission for between 5 months and 2 years. Michel Sadelain of the Memorial Sloan-Kettering Cancer Center in New York, co-leader of the group that designed the trial, says that a second trial of 50 patients is being readied,...

    Mitochondrial transfer could reduce the risk of childhood disease. Researchers say that technology to shuffle genetic material between unfertilized eggs is ready to make healthy babies. The technique could allow parents to minimize the risk of a range of diseases related to defects in the energy-producing cell organelles known as mitochondria. Mitochondrial defects affect an estimated 1 in 4,000 children, and can cause rare and often fatal diseases such as carnitine deficiency, which prevents the body from using fats for energy. They are also implicated in a wide range of more common diseases affecting children and adults, such as multiple...

    Two of the holy grails of medicine - stem cell technology and precision gene therapy - have been united for the first time in humans, say scientists.It means patients with a genetic disease could, one day, be treated with their own cells. A study in Nature corrected a mutation in stem cells made from a patient with a liver disease. Researchers said this was a "critical step" towards devising treatments, but safety tests were still needed. At the moment, stem cells created from a patient with a genetic illness cannot be used to cure the disease as those cells would...

    A gene silencing approach can save monkeys from high doses of the most lethal strain of Ebola virus in what researchers call the most viable route yet to treating the deadly and frightening infection. They used small interfering RNAs or siRNAs, a new technology being developed by a number of companies, to hold the virus at bay for a week until the immune system could take over. Tests in four rhesus monkeys showed that seven daily injections cured 100 per cent of them. U.S. government researchers and a small Canadian biotech company, Tekmira Pharmaceuticals, worked together to develop the new...

    Functionalised gold nanoparticles make a more efficient and versatile delivery system for use in gene therapy and cancer treatment, claim Korean scientists. Gold nanoparticles are non-toxic and easily made and so provide an effective way to deliver therapeutic antisense DNA to disease causing genes. Antisense DNA that is covalently attached to the nanoparticles will bind to messenger RNA of a disease causing gene, preventing translation and therefore inactivating it. But previous systems could deliver only antisense DNA that was covalently cross-linked to gold nanoparticles, which needed to be individually synthesized for each gene of interest. Now, Kangseok Lee and Min Su Han at...
  • Gene Therapy Cures Canines of Inherited Form of Day Blindness, Penn Veterinary Researchers Say

    04/21/2010 10:00:39 AM PDT · by decimon · 4 replies · 139+ views
    Veterinary ophthalmology researchers from the University of Pennsylvania have used gene therapy to restore retinal cone function and day vision in two canine models of congenital achromatopsia, also called rod monochromacy or total color blindness. Achromatopsia is a rare autosomal recessive disorder with an estimated prevalence in human beings of about 1 in 30,000 to 50,000. It primarily affects the function of the cone photoreceptors in the retina and serves as a representative model for other more common inherited retinal disorders affecting cones. Cone function is essential for color vision, central visual acuity and most daily visual activities, which underlines...
  • Second Dose Of Gene Therapy For Inherited Blindness Proves Safe In Animal Study

    Gene therapy for a severe inherited blindness, which produced dramatic improvements last year in 12 children and young adults who received the treatment in a clinical trial, has cleared another hurdle. The same research team that conducted the human trial now reports that a study in animals has shown that a second injection of genes into the opposite, previously untreated eye is safe and effective, with no signs of interference from unwanted immune reactions following the earlier injection. These new findings suggest that patients who benefit from gene therapy in one eye may experience similar benefits from treatment in the...
  • Longevity Tied to Genes That Preserve Tips of Chromosomes

    (BRONX, NY) — A team led by researchers at Albert Einstein College of Medicine of Yeshiva University has found a clear link between living to 100 and inheriting a hyperactive version of an enzyme that rebuilds telomeres — the tip ends of chromosomes. The findings appear in the latest issue of the Proceedings of the National Academy of Sciences. Telomeres play crucial roles in aging, cancer and other biological processes. Their importance was recognized last month, when three scientists were awarded the 2009 Nobel Prize in Physiology and Medicine for determining the structure of telomeres and discovering how they protect...

    A treatment based on HIV finds first success in humans.Researchers have halted a fatal brain disease by delivering a therapeutic gene to the stem cells that mature into blood cells. The gene was transferred using a virus derived from HIV, a technique that researchers have pursued for more than a decade but has not been successful in humans until now. Together with his colleagues, paediatric neurologist Patrick Aubourg at INSERM — France's main biomedical research agency — and at the Saint-Vincent de Paul Hospital in Paris, developed the system to treat X-linked adrenoleukodystrophy (ALD), a neurodegenerative disease that affects young...

    Introducing three genes corrects motor defects in monkeys.A potential gene therapy for Parkinson's disease can correct motor deficits in monkeys without causing the jerky, involuntary movements that often accompany long-term treatments for the disease. The approach is undergoing preliminary testing in a handful of human patients, who have all shown promising signs of improvement.At present, the most common remedy for Parkinson's disease involves replacing dopamine — the neurotransmitter that is depleted in patients with the disease — by administering the dopamine precursor levodopa, or L-DOPA. Most patients initially regain near-normal motor control, but after several years on L-DOPA the majority...

The approach combines elements of vaccines and gene therapy, and experts say the development could eventually lead to a vaccinelike weapon against AIDS--a goal that has thus far proved elusive. Vaccines work by priming the "adaptive" immune system to recognize and attack a specific invader. But despite 2 decades of research, several potential AIDS vaccines have failed to teach the immune system to...
