Boosting heart’s natural ability to recover after heart attack

This switch is driven by p53, the well-documented tumor-suppressing protein. The UNC researchers showed that increasing the level of p53 in scar-forming cells significantly reduced scarring and improved heart function after heart attack. The finding, which was published today in the journal Nature, shows that it is possible to limit the damage wrought by heart attacks, which strike nearly one million people in the United States each year. Heart disease accounts for one in four deaths every year…

Personalized cellular therapy achieves complete remission in 90 percent of acute lymphoblastic leukemia patients studied

The new data, which builds on preliminary findings presented at the American Society of Hematology’s annual meeting in December 2013, include results from the first 25 children and young adults (ages 5 to 22) treated at the Children’s Hospital of Philadelphia and first five adults (ages 26 to 60) treated at the Hospital of the University of Pennsylvania. Twenty-seven of the 30 patients in the studies achieved a complete remission after receiving an infusion of these engineered “hunter” cells, and 78 percent of the patients were alive six months after treatment. “The patients who participated in these trials had relapsed as many as four times, including 60 percent whose cancers came back even after stem cell transplants. Their cancers were so aggressive they had no treatment options left,” said the study’s senior author, Stephan Grupp, MD, PhD, a professor of Pediatrics in Penn’s Perelman School of Medicine and director of Translational Research in the Center for Childhood Cancer Research at the Children’s Hospital of Philadelphia…

Obesity accelerates aging of the liver, researchers find using novel biological aging clock

Although it had long been suspected that obesity ages a person faster, it hadn’t been possible to prove the theory, said study first author Steve Horvath, a professor of human genetics at the David Geffen School of Medicine at UCLA and a professor of biostatistics at the UCLA Fielding School of Public Health. …

Elevated cholesterol, triglycerides may increase risk for prostate cancer recurrence — ScienceDaily

“While laboratory studies support an important role for cholesterol in prostate cancer, population-based evidence linking cholesterol and prostate cancer is mixed,” said Emma Allott, PhD, postdoctoral associate at Duke University School of Medicine in Durham, North Carolina. “Understanding associations between obesity, cholesterol, and prostate cancer is important given that cholesterol levels are readily modifiable with diet and/or statin use, and could therefore have important, practical implications for prostate cancer prevention and treatment. “Our findings suggest that normalization, or even partial normalization, of serum lipid levels among men with dyslipidemia [abnormal lipid profile] may reduce the risk of prostate cancer recurrence,” said Allott. Allott, Stephen Freedland, MD, associate professor of surgery at Duke University School of Medicine, and colleagues, analyzed data from 843 men who underwent radical prostatectomy after a prostate cancer diagnosis and who never took statins before surgery. …

Glioblastma multiforme: Researchers find promise in new treatments

In a review paper published in the October issue of Neuro-Oncology, the researchers discuss various targeted therapies against IL13Rα2 and early successes of clinical trials with these therapies in the treatment of GBM. The paper also highlights the need for future trials to improve efficacy and toxicity profiles of targeted therapies in this field. …

Neuroscientists use snail research to help explain ‘chemo brain’

In an effort to solve this mystery, neuroscientists at The University of Texas Health Science Center at Houston (UTHealth) conducted an experiment in an animal memory model and their results point to a possible explanation. Findings appeared in The Journal of Neuroscience. In the study involving a sea snail that shares many of the same memory mechanisms as humans and a drug used to treat a variety of cancers, the scientists identified memory mechanisms blocked by the drug. …

New educational modules harness power of e-learning for pancreatic cancer education

The ePOSSOM endeavour was jointly developed by ecancer and the Severn Postgraduate School of Surgery, where surgical trainees led by Miss Katrina Butcher developed the content of the modules, providing key educational information for other surgical trainees and healthcare professionals. “ePOSSOM creates innovative e-learning material for audiences across the world, allowing each learner access to complex evidence-based medicine, wherever their learning environment allows them,” Miss Butcher writes in the accompanying editorial. These modules follow the UK ISCP (Intercollegiate Surgical Curriculum Programme) Curriculum, and aim to be a concise, up-to-date best evidence resource, for either new learning or revision. Experts from across the UK have contributed to and peer-reviewed the modules to ensure that the content is of the highest scientific quality — and poised on the frontier of pancreatic cancer knowledge. …
