Gut microbiome analysis improved noninvasive colorectal cancer screening
Analysis of the gut microbiome more successfully distinguished healthy individuals from those with precancerous adenomatous polyps and those with invasive colorectal cancer compared with assessment of clinical risk factors and fecal occult blood testing, according to data published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Largest cancer genomic study proposes 'disruptive' new system to reclassify tumors
After analyzing more than 3,500 tumors on multiple technology platforms TCGA researchers say cancers are more likely to be similar based on their cell type of origin as opposed to their tissue type of origin. The study suggests at least 10 percent of cancer patients would be classified differently under this protocol. But Buck faculty Christopher Benz thinks this fraction will swell when more samples and additional tumor types are included in the next analysis.

Cancer study reveals powerful new system for classifying tumors
Cancers are classified primarily on the basis of where in the body the disease originates, as in lung cancer or breast cancer. According to a new study, however, one in 10 cancer patients would be classified differently using a new classification system based on molecular subtypes instead of the current tissue-of-origin system. This reclassification could lead to different therapeutic options for those patients.

Dramatic growth of grafted stem cells in rat spinal cord injuries
Building upon previous research, scientists at the University of California, San Diego School of Medicine and Veteran's Affairs San Diego Healthcare System report that neurons derived from human induced pluripotent stem cells and grafted into rats after a spinal cord injury produced cells with tens of thousands of axons extending virtually the entire length of the animals' central nervous system.

Single-cell analysis holds promise for stem cell and cancer research
UC San Francisco researchers have identified cells' unique features within the developing human brain, using the latest technologies for analyzing gene activity in individual cells, and have demonstrated that large-scale cell surveys can be done much more efficiently and cheaply than was previously thought possible.

Galápagos hawks hand down lice like family heirlooms
Studying Galápagos hawks and their lice, a University of Arizona-led research team provides some of the first field evidence for co-divergence between parasites and hosts as a major driver of biodiversity. As the birds diversify into distinct populations on each island, their parasites diversify with them. The findings help explain the rapid rate of parasite evolution.

Brain tumors fly under the body's radar like stealth jets, new U-M research suggests
Brain tumors fly under the radar of the body's defense forces by coating their cells with extra amounts of a specific protein, new research shows. Like a stealth fighter jet, the coating means the cells evade detection by the early-warning immune system that should detect and kill them. The stealth approach lets the tumors hide until it's too late for the body to defeat them.

Discovery yields master regulator of toxin production in staph infections
St. Jude Children's Research Hospital scientists have discovered an enzyme that regulates production of the toxins that contribute to potentially life-threatening Staphylococcus aureus infections. The study recently appeared in the scientific journal the Proceedings of the National Academy of Sciences. Researchers also showed that the same enzyme allows Staphylococcus aureus to use fatty acids acquired from the infected individual to make the membrane that bacteria need to grow and flourish.

Stowers researchers reveal molecular competition drives adult stem cells to specialize
Adult organisms ranging from fruit flies to humans harbor adult stem cells, some of which renew themselves through cell division while others differentiate into the specialized cells needed to replace worn-out or damaged organs and tissues. Understanding the molecular mechanisms that control the balance between self-renewal and differentiation in adult stem cells is an important foundation for developing therapies to regenerate diseased, injured or aged tissue.

Pyruvate oxidation is critical determinant of pancreatic islet number and β-cell mass
Glucose is not only a major nutrient regulator of insulin secretion but also impacts on gene expression in β-cells. Using a mouse model of β-cell-specific knock-out of Pdha1 gene which encodes the α subunit of the pyruvate dehydrogenase component of the pyruvate dehydrogenase complex, the authors demonstrated that mitochondrial metabolism of pyruvate derived from glucose not only regulates insulin secretion but also directly influences β-cell growth and plasticity.

Marital tension between mom and dad can harm each parent's bond with child, study finds
Children suffer when mom and dad have problems in their marriage, according to a new study. Dads, especially, let negative emotions and tension from their marriage spill over and harm the bond with their child, says psychologist and lead-author Chrystyna Kouros, Southern Methodist University, Dallas. Conversely, moms in poor quality marriages sometimes compartmentalized marital tension and improved the relationship with their child. The findings indicate marriage quality closely affects the parent-child bond, Kouros said.

Rituals can help older people remember to take their asthma meds
Storing asthma medication in the bathroom and making it part of a daily routine may be helpful advice that doctors can give their older asthmatic patients who struggle to remember to take their daily prescribed medication. This advice comes from Alex Federman, senior author of a study which discusses how elderly asthmatics cope with taking their inhaled corticosteroid medication as prescribed. The findings appear in the Journal of General Internal Medicine, published by Springer.

Seamless gene correction of beta-thalassemia mutations in patient-specific cells
A major hurdle in gene therapy is the efficient integration of a corrected gene into a patient's genome without mutating off-target sites. In a paper published today in Genome Research, scientists have used CRISPR/Cas genome editing technology to seamlessly and efficiently correct disease-causing mutations in cells from patients with beta-thalassemia.

Monthly preventative treatment with a new drug combination reduces malaria in children
Preventative treatment with a monthly dose of a newer antimalarial drug can reduce the risk of malarial infection among young children, according to a study published in this week's PLOS Medicine. The study, conducted by Victor Bigira and colleagues at San Francisco General Hospital and the Makerere University College of Health Sciences in Kampala, Uganda, finds that treating young children with dihydroartemisinin-piperaquine decreased their risk of contracting malaria.

An embryonic cell's fate is sealed by the speed of a signal
Early in development, chemical signals tell cells whether to turn into muscle, bone, brain or other tissue. By tracking cells' responses to signals, researchers found the speed at which the signal arrives has an unexpected influence on that decision.

Eating baked or broiled fish once a week is good for the brain, regardless of how much omega-3 fatty acid it contains, according to researchers at the University of Pittsburgh School of Medicine. The findings, published online recently in the American Journal of Preventive Medicine, add to growing evidence that lifestyle factors contribute to brain health later in life.
