Repairing mutations in human mitochondria

Posted: Published on March 12th, 2012

LOS ANGELES Researchers at the UCLA stem cell center and the departments of chemistry and biochemistry and pathology and laboratory medicine have identified, for the first time, a generic way to correct mutations in human mitochondrial DNA by targeting corrective RNAs, a finding with implications for treating a host of mitochondrial diseases. Mutations in the human mitochondrial genome are implicated in neuromuscular diseases, metabolic defects and aging. There currently are no methods to successfully repair or compensate for these mutations, said study co-senior author Dr. Michael Teitell, a professor of pathology and laboratory medicine and a researcher with the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. Between 1,000 and 4,000 children per year in the United States are born with a mitochondrial disease and up to one in 4,000 children in the U.S. will develop a mitochondrial disease by the age of 10, according to Mito Action, a nonprofit organization supporting research into mitochondrial diseases. In adults, many diseases of aging have been associated with defects of mitochondrial function, including diabetes, Parkinson's disease, heart disease, stroke, Alzheimer's disease and cancer. "I think this is a finding that could change the field," Teitell said. … Continue reading

Studies Highlight Nuvilex Cell-In-A-Box® Technology Enhances Chemotherapy Effectiveness

Posted: Published on March 12th, 2012

SILVER SPRING, Md.--(BUSINESS WIRE)-- Nuvilex, Inc. (OTCQB:NVLX), an emerging biotechnology provider of cell and gene therapy solutions, today discussed the use of the proprietary Cell-in-a-Box technology, being acquired from SG Austria, as an adjunct to chemotherapy across a spectrum of cancer treatments. The Cell-in-a-Box technology involves the encapsulation of cytochrome P450 expressing cells which are placed beside the target tumor. When the patient is injected with the nontoxic drug ifosfamide, the encapsulated cells transform this prodrug into its active, chemotherapeutic drug. The greatest benefit of this treatment protocol is that the treatment is localized to the tumor, enhancing the chemotherapys effectiveness. Most chemotherapy drugs affect both normal and cancerous tissue, which is why they also are toxic to naturally fast-growing cells in the body such as hair follicles and intestinal cells. Ifosfamide was one of many drugs originally used for pancreatic cancer that showed an effect against the tumor, but produced severe side effects. By using encapsulated cytochrome P450 expressing cells to convert the ifosfamide at the tumor site, the encapsulated cell treatment was able to localize the drug's effects within the tumor cells. The amount of drug needed was decreased to only one third of the original dose and … Continue reading

Painkiller prescriptions after minor surgery puts patients at risk of addiction: study

Posted: Published on March 12th, 2012

carys mills Globe and Mail Update Published Monday, Mar. 12, 2012 4:46PM EDT Last updated Monday, Mar. 12, 2012 4:50PM EDT Patients who are prescribed opioids within a week of minor surgery are at risk of becoming chronic users, according to a Canadian study published Monday. Researchers say tailored post-operative plans are needed to make sure patients arent being given painkillers that they dont need or ones that are too strong. Some 391,139 Ontario patients were studied by researchers from the Institute for Clinical Evaluative Sciences and St. Michaels Hospital. All were 66 or older and had low-pain operations, such as for cataracts, gallbladder removal, prostate tissue removal or varicose vein stripping. Within a week of surgery, 7 per cent were given opioids, including codeine and oxycodone the generic name for OxyContin according to the study. One year later, more than 10 per cent of them were continuing to use the medications. We think part of the reasoning behind these things occurring is because there are standardized templates for discharge from hospital, said Chaim Bell, the senior researcher of the study, which was published in the Archives of Internal Medicine. [The templates] are not well tailored to some of the … Continue reading

Chemotherapy Side Effects Could Be Reduced, Research

Posted: Published on March 12th, 2012

Chemotherapy - a grueling treatment of cancer-busting chemicals - could become less toxic for patients based on new research into how cells shuttle the drugs inside. For chemotherapy to work, the chemical brew must enter cells through gatekeeper transporters and Sunday, researchers at Duke University revealed the structure of one transporter important in the shuttling of chemotherapy drugs into cells. The result could result in smarter design of chemotherapy drugs that enter into more cancerous cells and avoid healthy cells, the researchers said. "Knowing the structure and properties of the transporter molecule may be the key to changing the way that some chemotherapies, for example, could work in the body to prevent tumor growth," Seok-Yong Lee, assistant biochemistry professor at Duke University and senior author, said in a statement. The journal Nature published the study online Sunday. Chemotherapy treatments typically result in a host of side effects, including anemia, hair loss, fatigue and nausea, according to the National Cancer Institute. Like us on Facebook The research points to one approach doctors could use to reduce chemotherapy drug levels in patients and thereby reduce side effects. The focus of the study was a transporter that shuttles molecules made of nucleic acids … Continue reading

New discovery 'could trim down side effects of chemotherapy'

Posted: Published on March 12th, 2012

London, Mar 12 (ANI): Scientists have determined the structure of a key molecule that can carry chemotherapy and anti-viral drugs into cells, which could help to create more effective drugs with fewer effects to healthy tissue. The transporter molecule, called a concentrative nucleoside transporter, works by moving nucleosides, the building blocks of DNA and RNA, from the outside to the inside of cells. "Knowing the structure and properties of the transporter molecule may be the key to changing the way that some chemotherapies, for example, could work in the body to prevent tumor growth," Seok-Yong Lee, senior author of the study from Duke University, said. The transporter molecule also transports nucleoside-like chemo drugs through cell membranes. Once inside the cells, the nucleoside-like drugs are modified into nucleotides that are incorporated into DNA in ways that prevent tumour cells from dividing and functioning. "We discovered the structure of the transporter molecule, and now we believe it is possible to improve nucleoside drugs to be better recognized by a particular form of the transporter molecule that resides in certain types of tissue. "Now we know the transporter molecule has three forms, which recognize different drugs and reside in different tissues," Lee said. … Continue reading

Discovery could mean fewer chemo side effects

Posted: Published on March 12th, 2012

While it can often work wonders against invading cancer cells, chemotherapy can also bring on very undesirable side effects, such as hair loss, nausea and vomiting. But the recent discovery of the structure of a certain molecule could potentially lead to the development of new drugs that could target tumors while avoiding damage to healthy tissue, resulting in possibly fewer side effects. The molecule, known as a transporter, can carry specific anticancer and antiviral drugs directly into cells. The drugs can then prevent tumor cells from dividing and multiplying. "If you really know what this transporter looks like, you can potentially design a cancer drug to be recognized by this transporter and carried into the cells, and you can lower the dose of cancer drugs and decrease the side effects as a result," said Seok-Yong Lee, an assistant professor of biochemistry at Duke University School of Medicine and lead author of the research, published online in the journal Nature. Experts not involved with Lee's research say development of such drugs is still a very long way off, but focusing on the ability of a drug to get into cancer cells makes scientific sense. "If it could be manipulated to help … Continue reading
