New genomic editing methods produce better disease models from patient-derived iPSCs

New genomic editing methods produce better disease models from patient-derived iPSCs
2014-09-08
(Press-News.org) New Rochelle, NY, September 8, 2014—Highly valuable for modeling human diseases and discovering novel drugs and cell-based therapies, induced pluripotent stem cells (iPSCs) are created by reprogramming an adult cell from a patient to obtain patient-specific stem cells. Due to genetic variation, however, iPSCs may differ from a patient's diseased cells, and researchers are now applying new and emerging genomic editing tools to human disease modeling, as described in a comprehensive Review article published in Stem Cells and Development, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Stem Cells and Development website until September 30, 2014.

In "Genomic Editing Tools to Model Human Diseases with Isogenic Pluripotent Stem Cells," Ihor Lemischka, Huen Suk Kim, Jeffrey Bernitz, and Dung-Fang Lee, Icahn School of Medicine at Mount Sinai (New York, NY), provide a detailed overview of the development of patient-specific iPSCs for modeling a disease. The authors describe the many factors that need to be considered when generating an iPSC-based disease model comprised of cells that are genetically identical, and they discuss the advantages and limitations of the three leading genomic editing tools: zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and the most recent, the clustered regularly interspaced short palindromic repeat (CRISPR) system.

"As our appreciation of iPSCs as primarily therapeutic screens and disease models matures, we look to advanced gene editing tools to assist in appropriate experimental design. Ihor Lemischka and colleagues provide a much needed examination of the advantages and shortcomings of such techniques," says Editor-in-Chief Graham C. Parker, PhD, The Carman and Ann Adams Department of Pediatrics, Wayne State University School of Medicine, Detroit, MI.

Living in the shadow of Mauna Loa: A silent summit belies a volcano's forgotten fury

2014-09-08
Alexandria, Va. — Earth's largest active volcano, Mauna Loa on Hawaii's Big Island, is taking a nap. And after 30 years, no one is sure when the sleeping giant will awaken. Scientists say it's likely to erupt again within the next couple of decades and, when it does, it will be spectacular — and potentially dangerous. Although Mauna Loa often takes a back seat to the more famous Kilauea, which has been erupting nearly continuously since 1983, history warns us that Mauna Loa's current silence is anomalous. Meanwhile, more people and more buildings pack into potentially ...

Whale sex: It's all in the hips

Whale sex: Its all in the hips
2014-09-08
Both whales and dolphins have pelvic (hip) bones, evolutionary remnants from when their ancestors walked on land more than 40 million years ago. Common wisdom has long held that those bones are simply vestigial, slowly withering away like tailbones on humans. New research from USC and the Natural History Museum of Los Angeles County (NHM) flies directly in the face of that assumption, finding that not only do those pelvic bones serve a purpose – but their size and possibly shape are influenced by the forces of sexual selection. "Everyone's always assumed that if you ...

Study puts some mussels into Bay restoration

Study puts some mussels into Bay restoration
2014-09-08
Restoring oysters—and their ability to filter large volumes of water—is widely seen as a key way to improve the health of Chesapeake Bay. New research makes this calculus even more appealing, showing that the mussels that typically colonize the nooks and crannies of a restored oyster reef can more than double its overall filtration capacity. The study—by researchers at the University of Maryland, the Smithsonian Environmental Research Center, and the Virginia Institute of Marine Science—appears as the cover story in the most recent issue of Restoration Ecology. "Many ...

New targets for treating pulmonary hypertension found

2014-09-08
Two new potential therapeutic targets for the treatment of pulmonary arterial hypertension, a deadly disease marked by high blood pressure in the lungs, have been identified by researchers at the University of Illinois at Chicago. Their findings are reported in the American Journal of Respiratory and Critical Care Medicine. Early symptoms of pulmonary arterial hypertension include shortness of breath and exercise intolerance. As the disease progresses, patients may require oxygen supplementation and lung transplantation. Heart failure can develop and is a major cause of ...

New compound inhibits enzyme crucial to MERS and SARS viruses, with a catch

2014-09-08
Scientists at the University of Illinois, Chicago, have identified a compound that effectively inhibits an enzyme crucial to the viruses that cause Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). The compound appears to have a different method of inhibition in each virus due to slight differences in each virus' enzyme which means finding other compounds that inhibit both may be difficult according to research presented at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) an infectious disease meeting ...

How quickly viruses can contaminate buildings and how to stop them

2014-09-08
Using tracer viruses, researchers found that contamination of just a single doorknob or table top results in the spread of viruses throughout office buildings, hotels, and health care facilities. Within 2 to 4 hours, the virus could be detected on 40 to 60 percent of workers and visitors in the facilities and commonly touched objects, according to research presented at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), an infectious disease meeting of the American Society for Microbiology. There is a simple solution, though, says Charles ...

A low-energy optical circuit for a new era of technology

2014-09-08
Unlike electronic circuits, optical, or "photonic", circuits work with light rather than electricity, which makes them 10 to 100 times faster. They are also more energy-efficient because they show lower heat loss, better signal-to-noise ratios and are less susceptible to interference. Used especially for communications (e.g. fiber optics), optical circuits may use tiny optical cavities as 'switches' that can block or allow the flow of light, similarly to transistors in electronics. EPFL scientists have now fabricated and experimentally tested a silicon-based 'photonic crystal ...

To admit or not to admit: Variation in hospitalizations from ER costs billions

2014-09-08
ANN ARBOR, Mich. — It sounds like the setup for a joke: Two identical patients go to two different hospital emergency entrances, complaining of the same symptoms. But what happens next is no laughing matter, according to a new University of Michigan study published in the September issue of Health Affairs. While one patient may get treated and released from the emergency department, the other gets sent upstairs to a hospital bed – at a cost of tens of thousands of dollars. In fact, doctors at one hospital may be as much as six times as likely to admit an emergency ...

Scientists reveal cell secret potentially useful for vaccines

Scientists reveal cell secret potentially useful for vaccines
2014-09-08
The best defense is a good offense, especially when it comes to the immune system. The troops that respond to an infection are split into two squadrons, and, until recently, it seemed that the two were independent, without much interaction. Now, in a paper published this week in Nature Immunology, a team of scientists from the Virginia Tech Carilion Research Institute and the University of Alabama at Birmingham say that the immunology boot camp is more communication-intensive than initially thought — a discovery that could help efforts to produce more effective vaccines. "We ...

Women and health professionals spark new cycle of improving maternal and newborn health

Women and health professionals spark new cycle of improving maternal and newborn health
2014-09-08
Demand for better care by women linked with the expansion of basic services, rather than political pressure, has helped to improve midwifery services in low to middle-income countries, according to international research involving the University of Southampton. An examination of maternal and newborn health systems for the Lancet Series on Midwifery found that after initial investment in maternal and newborn health infrastructure, a virtuous cycle developed in these countries – with increased demand for care leading to the deployment of more midwives, better services, ...
