Regenerative medicine raises hope

By Jeff Hansel The Post-Bulletin, Rochester MN

Even as regenerative medicine emerges as a new hope for many, doctors caution that it takes time to get a new discovery from the research lab to patient treatment.

As an example, one type of regenerative medicine, treatment of blood cancer disorders, has taken about 50 years to develop, said Mayo Clinic heart specialist Dr. Andre Terzic,director of Mayo's regenerative medicine center.

"We want to make sure that we are not creating a hype in the society but that we are really offering hope for patients, and ultimately definitive solutions," he said.

Yet it might be hard for people awaiting cures to contain their excitement.

"It has clearly gone from science fiction into rigorous science, and now from science it's going into practice," Terzic said. "It's not yet a broadly-offered servicebut it's in the phase of rigorous clinical trials."

Dr. Stephen Russell, Mayo Clinic's associate director for translation, says"we can't just take what we did in the mouse and apply it in the clinic."

"What we have to do is we have to develop a clinical protocol, we have to scale up the manufacture of the product that we're going to use, which may involve the scaled culturing of cells from a patient," he said.

Human research studies must pass muster from the Institutional Review Board at Mayo as well as from the FDA.

"That process with your foot hard on the accelerator is probably a two- to three-year process," Russell said.

Pluristem shares bounce back after Thursday plunge

NEW YORK (AP) Shares of biotechnology company Pluristem Therapeutics Inc. bounced back Friday after the company responded to a report that a patient treated with its PLX stem cell therapy had died.

THE SPARK: Bloomberg BusinessWeek reported Thursday that Pluristem did not disclose the death of a young patient who had been treated with its placental cell therapy before a $32 million public stock sale in September. Shares of Pluristem fell 23 percent Thursday.

The Israeli company said Thursday evening that parts of the article were inaccurate or misleading. It said the patient, a Romanian girl whose name has not been disclosed, was "in imminent danger of death" at the time she was treated with the stem cells. She was not part of an organized clinical trial and was treated on a compassionate basis because no therapy options remained.

Pluristem said the patient lived for six months after her treatment. She returned to Romania four months before she died and the company was not monitoring her health. Pluristem said it was not aware of her death at the time it sold the additional stock. Bloomberg said the patient died Sept. 12, the day the stock sale was announced. The sale closed a week later.

"The formal report relating to the death clearly stated that there was no connection between the PLX cell treatment and the death of the patient," Pluristem said in a press release.

THE BIG PICTURE: Pluristem said that three patients have been treated with PLX on a compassionate basis including the Romanian girl and two have died. The company said it believes the patients lived longer than expected following treatment, which demonstrates that PLX therapy can be effective. The company is studying the stem cells as a treatment for peripheral artery disease, nerve pain, and other conditions.

THE STOCK: Shares of Pluristem rose 39 cents, or 13.7 percent, to $3.24 on Friday. The stock reached an annual high of $5 per share in August, and including Friday's gains, the shares are down 29 percent since the company announced the stock offering.

DOH to regulate stem cell therapy in PH

Published on 10 November 2012 Hits: 38 Written by Jovee Marie N. Dela Cruz

The Department of Health (DOH) on Friday said that it has become necessary to issue regulations for stem cell therapy in the country. Health Secretary Enrique Ona said that guidelines for clinics offering stem cell therapy will be released immediately by the DOH and the Food and Drug Administration.

We will issue guidelines because here in the country we dont know where the stem cell offered by clinics come from, he said.

According to the DOH, stem cell therapy belongs to the category of advanced cell therapy, which includes biologics and blood. Many countries apply a risk-based approach to assess the quality, efficacy and safety of advanced cell therapy.

In many countries, stem cell is considered an investigational intervention, Ona said.

The DOH said that stem cell research employs both autologous (from same person) or allogenic (from another organism like an animal or another human cell or tissue sample) method.

Ona said that because there are many steps in the preparation of this lab and invasive procedure, there is a need to have a regulatory framework to protect Filipino citizens.

The European Commission has given its seal of approval to the continents first gene therapy a treatment for a lipid-processing disorder which will be sold in Europe beginning in late 2013, The Scientist reports.

According to the article, the EC has approved the use of Glybera, a therapy that utilizes viral vectors to deliver DNA encoding a lipid-processing enzyme to patients lacking a functional copy due to a gene mutation.

Glybera was developed by Amsterdam-based uniQure for patients suffering from a rare lipid-processing disease, called lipoprotein lipase deficiency, caused by loss-of-function mutations in the liproprotein lipase gene, The Scientist adds. The therapy is indicated for LPLD patients with severe symptoms such as life-threatening bouts of pancreatitis.

Katherine High, a pediatrician at the University of Pennsylvania and Childrens Research Hospital of Philadelphia and who was not involved in research on Glybera, notes that this marks the first time that a gene therapy has been judged safe and efficacious for human clinical use, according to regulatory standards used in Europe and the United States.

The Scientist also reports that UniQure is applying for approval from the US Food and Drug Administration and is also looking to bring Glybera to Korea, Israel, and countries in South America. Currently, no gene therapies have been approved for use in the United States.

Mesothelioma drug slows disease progression in patients with an inactive NF2 gene

Public release date: 8-Nov-2012 [ | E-mail | Share ]

Contact: Emma Mason wordmason@mac.com ECCO-the European CanCer Organisation

Preliminary findings from the first trial of a new drug for patients with mesothelioma show that it has some success in preventing the spread of the deadly disease in patients lacking an active tumour suppressor gene called NF2. The study is presented at the 24th EORTC-NCI-AACR [1] Symposium on Molecular Targets and Cancer Therapeutics in Dublin, Ireland, today (Friday) [2].

Mesothelioma, which is usually caused by exposure to asbestos, has few treatment options and patients usually die within 9-17 months of diagnosis. Previous research has shown that the gene NF2, which produces a protein called merlin, is frequently inactivated in approximately 50% of mesotheliomas. Merlin negatively regulates another protein called focal adhesion kinase (FAK) in mesothelioma, and so when NF2 and merlin are inactivated, the activity of FAK is increased and mesothelioma cells become invasive and start to spread. When NF2 and merlin activity is restored, FAK activity and cell invasion are decreased.

Professor Jean-Charles Soria, Professor of Medicine and Medical Oncology at South Paris University and head of early drug development at the Institut Gustave Roussy in Paris (France), said: "This suggested that if we could inhibit FAK in mesothelioma patients, it might slow or stop the spread of the disease. Pre-clinical work has shown that an agent, currently known as GSK2256098, is a potent and specific inhibitor of FAK. Early in the clinical study presented today, a patient with mesothelioma, who had progressed quickly on prior therapies, had prolonged stable disease while on GSK2256098, which is suggestive of clinical activity."

Prof Soria and colleagues at nine centres in France, Australia and the United Kingdom recruited 29 mesothelioma patients to the phase I study of GSK2256098, starting in July 2010. The study is continuing.

The mesothelioma patients took the drug orally in capsule form twice a day at doses ranging from 300 - 1500 mg, with the majority (22) taking 1000 mg a day. There were no complete or partial responses; 14 patients had stable disease, nine had progressive disease, three had non-measurable disease, and three left the study before evaluation of response. Overall, patients had an average of 17 weeks before the disease progressed.

However, in patients in whom merlin was inactivated, the average time before the disease progressed was 24 weeks, compared to 11 weeks in patients with active merlin and nearly 11 weeks in patients in whom the activity of merlin was unknown.

Adverse side-effects were mainly low grade and tolerable.

"These findings are important but preliminary," said Prof Soria. "They show that merlin is a potential biomarker in mesothelioma that may enable us to identify a subset of patients who could benefit from GSK2256098 and have longer, progression-free survival. Mesothelioma is a deadly disease without many treatment options, and therefore identification of novel and effective therapies is needed."

One Small Gene Mutation Leads to One Giant Leap for Alzheimer’s Research

As the sixth leading cause of death in the United States, Alzheimers affects approximately five million adults and is estimated to cost the country $200 billion this year in terms of direct medical fees and other costs associated with caregivers and therapies. Since the first records of the disease by Alois Alzheimer in 1906, Alzheimers disease (AD) has become increasingly prevalent in our worldwide population, and scientists have been struggling for decades in efforts to figure out the causation of the disease and, most importantly, how to treat it. Having worked in laboratories that dedicate their work to studying neurodegenerative diseases, Ive realized that there is an immense amount of technology, effort and time that has been put into finding just one more small piece to this puzzle even a breakthrough in discovering the involvement of a protein in a disease, or how a specific mutation can contribute to its exacerbation, is an encouragement in the scientific field.

There are two essential cortical biomarkers of AD plaques, which are formed of beta-amyloid protein deposits, and tangles, comprised of the tau protein that builds up inside of cells. Current therapies have been targeting the aggregation of these proteins in hopes of detangling the deposits, as plaques and tangles contribute to massive cell and nerve death that lead to rapid cognitive decline, an inevitable symptom of AD.

The mechanism of protein accumulation is important to understand for researchers to determine the cause of buildup. Beta-amyloid (A) plaque fragments are a result of a cleavage reaction of the amyloid precursor protein (APP), a membrane protein that is found in neuronal synapses. Through post-translational modifications, APP can be separated into many different sections based on proteases and their specific cleavage sites (Fig. 1). Normally, the -secretase protease cleaves APP in the non-amyloidogenic pathway and the protein is rendered functional for other cellular tasks. However, when -secretase comes across APP and severs the protein at another site, it leaves open the sequence correlated to -secretase, the third enzyme that can come in and cleave APP. The result of these two cleavages is A.

Concerted efforts have been made to block the - and -secretase cleavage sites, and pharmaceutical companies are currently testing drugs for their efficacy in slowing down the rate of AD progression. However, researchers have questioned this direction, citing that these trials have been inconclusive or failed to control A formation.

What is particularly fascinating about this pathway is that perhaps our genetics unknowingly held part of the answer all along. In a recent finding published in Nature by a research team from DeCode Genetics based in Iceland, a rare gene mutation on APP was found to be protective against AD. This is the first mutation of its kind to be neuroprotective, as many other mutations of APP have exacerbated the AD phenotype. Whole genome sequencing of approximately 1800 Icelanders resulted in the discovery of this variant and researchers proved that it decreased the formation of A and protein aggregation by 40 percent. The single point mutation was present in slightly less than one percent of the Icelanders and statistical analysis shows that carriers of the variant were about twice as likely to reach the age of 85 than non-carriers. In addition, cognitive function of carriers in the age range of 80-100 was vastly improved in comparison to their counterparts.

As exciting as this finding is, we must keep in mind that only a small subset of Icelanders carries the protective variant and that the study should be extended to other populations for a broader analysis. Whole genome sequencing is also a relatively expensive effort that is not just a simple blood test at the doctors office, and you would need to conduct a specific test at a laboratory or genetics company to tell if you have the mutation. Another interesting fact is that carriers of the gene mutation also reap its protective advantages though this scientific discovery has proven that researchers are on the right track for targeting APP and preventing A formation in gene therapies, perhaps preventing APP cleavage entirely is unnecessary and only a partial reduction is needed for a therapeutic benefit.

There will always be caveats and exceptions to any scientific discovery, but the overall enthusiasm for this new insight has been greatly encouraging to the research community. With the increase of resources, technology and dedication to biomedical research in the past decade, I am positive that we will be able to step forward in our advancements to understand and develop therapies for those affected by neurodegenerative diseases.

Gene find turns soldier beetle defense into biotech opportunity

ScienceDaily (Nov. 7, 2012) New antibiotic and anti-cancer chemicals may one day be synthesised using biotechnology, following CSIRO's discovery of the three genes that combine to provide soldier beetles with their potent predator defence system.

CSIRO researchers, and a colleague at Sweden's Karolinska Institute, published details of the gene identification breakthrough and potential applications recently in the international journal Nature Communications.

"For the first time, our team has been able to isolate and replicate the three genes that combine to make the potent fatty acid that soldier beetles secrete to ward off predators and infection," said CSIRO Ecosystem Sciences research leader Dr Victoria Haritos.

"This discovery is important because it opens a new way for the unusual fatty acid to be synthesised for potential antibiotic, anti-cancer, or other industrial purposes," Dr Haritos said.

Soldier beetles exude a white viscous fluid from their glands to repel potential attacks from predators, as well as in a wax form to protect against infection.

The team found this fluid contains an exotic fatty acid called dihydromatricaria acid, or DHMA, which is one of a group called polyynes that have known anti-microbial and anti-cancer properties.

While DHMA and similar polyyne fatty acids are found in a wide variety of plants, fungi, liverworts, mosses, marine sponges and algae, these compounds have proved very difficult to manufacture using conventional chemical processes. However, Dr Haritos and her team have developed a way to achieve this.

"We have outlined a method for reproducing these polyyne chemicals in living organisms like yeast, using mild conditions" Dr Haritos said.

Soldier beetles are the only animals reported to contain DHMA. This, together with the observation that the beetles forage on plants (such as daisies) which contain a lot of these types of fatty acids, led to previous incorrect conclusions that the DHMA in soldier beetles was derived from their diet.

"Through our research and the gene differences we have discovered, we now know soldier beetles have evolved this same defensive compound entirely independently of its production in plants and fungi," Dr Haritos said.

Loss of Key Blood Cell Gene Tied to Anemia, Animal Research Suggests

WEDNESDAY, Nov. 7 (HealthDay News) -- Scientists have discovered a new gene, known as Atpif1, that enables the body to make hemoglobin -- the protein in red blood cells that is responsible for transporting oxygen in the blood.

In their study, researchers from Brigham and Women's Hospital in Boston revealed that loss of this critical blood cell gene seems to result in severe anemia or a lower than normal number of red blood cells or levels of hemoglobin. They said that the findings provide new insight into anemia and could lead to the development of improved treatments for the condition.

Using zebrafish, the researchers cloned the Atpif1 gene, which regulates the production of hemoglobin during the formation of red blood cells. They found the loss of this gene results in severe anemia.

After examining data on the human form of Atpif1, first study author Dhvanit Shah, of the hospital's division of hematology, and colleagues said the gene is essential for normal red blood cell differentiation. Any deficiency in this gene, they added, might play a role in certain human diseases.

Older people and women of childbearing age are at greater risk for anemia. Babies and children also are at risk for the condition due to iron deficiency from their diet or lead poisoning, the researchers said.

The study was published in the Nov. 7 online edition of the journal Nature.
