Faulty bioelectric signal responsible for facial defects caused by rare genetic disorder
Tufts University biologists have discovered that faulty bioelectric signaling is responsible for the skull and facial abnormalities that characterize the rare genetic disorder Andersen-Tawil syndrome (ATS). The finding shows it may be possible to alter bioelectrical signaling to correct effects of fetal alcohol syndrome and other developmental defects or genetic mutations.

Inhibiting age-related inflammation maintains healthy gut microbiota and extends lifespan
New research shows that age-related inflammation drives changes in the fruit fly gut-causing metaplasia or abnormal changes in cells. That metaplasia led to changes in the microbiota, which resulted in pathology and shorter lifespans. Researchers reduced inflammatory signaling in the gastric region of the fly gut, preventing metaplasia, maintaining a healthy commensal population, and extending lifespan in the flies by up to 18 percent. Metaplasias have been associated with human cancers and other diseases.

Wayne State University researchers discover new source of mutations in cancer
Recently, a new mutation signature found in cancer cells was suspected to have been created by a family of enzymes found in human cells called the APOBEC3 family. The study, 'Strand-biased Cytosine deamination at the Replication Fork causes Cytosine to Thymine Mutations in Escherichia coli,' led by Ashok Bhagwat, Ph.D., professor of chemistry in the College of Liberal Arts and Sciences at Wayne State University, was recently published in the Proceedings of the National Academy of Sciences.

New study finds interruption of radiation therapy risks cancer recurrence
Cancer patients who miss two or more radiation therapy sessions have a worse outcome than fully compliant patients, investigators at Montefiore Einstein Center for Cancer Care and Albert Einstein College of Medicine's NCI-designated Albert Einstein Cancer Center have found. The study, published in the International Journal of Radiation Oncology Biology Physics, suggests that this noncompliance to scheduled treatments may represent a new behavioral biomarker for identifying high-risk patients who require additional interventions to achieve optimal care outcomes.

Penn researchers illuminate 'dark side' of the transcriptome
A new way of mapping the collection of RNA read-outs that are expressed by a cell's active genes has been devised to shed additional light on the role of RNAs in cells. These 'dark' variations in RNA likely have roles in gene regulation across tissues, development, and in human diseases. The team will use the now-free software to interrogate cells in brain disorders, cancers, and other illnesses.

Scientists propose 'pumpjack' mechanism for splitting and copying DNA
New close-up images of the proteins that copy DNA inside the nucleus of a cell have led a team of scientists to propose a brand new mechanism for how this molecular machinery works. The scientists studied proteins from yeast cells, which share many features with the cells of complex organisms such as humans, and could offer new insight into ways that DNA replication can go awry.

Device hits pancreatic tumors hard with toxic 4-drug cocktail, sparing the body
A powerhouse team of researchers at the University of North Carolina at Chapel Hill has revealed that an implantable device can deliver a particularly toxic cocktail of drugs directly to pancreatic tumors to stunt their growth or in some cases, shrink them -- all while showing signs that the rest of the body would be spared toxic side effects.

More detailed analysis of how cells react to stress
Stress in the body's cells is both the cause and consequence of inflammatory diseases or cancer. The cells react to stress to protect themselves. Researchers at the University of Zurich have now developed a new technique that allows studying a fundamental response to stress in much more detail than previously possible: the ADP-ribosylation of chromatin. In the long term, this method could help finding ways of blocking disease-causing processes.

Removal of complex renal tumors performed safely by robotic surgery in selected patients
Renal cell carcinoma can sometimes spread to the inferior vena cava (IVC), the body's largest vein, posing a threat to the heart and brain. Robotic nephrectomy for inferior vena cava tumor thrombus has favorable outcomes in selected patients compared with open surgery, which can have a high rate of complications, report surgeons in The Journal of Urology®.

NIH researchers identify striking genomic signature shared by 5 types of cancer
National Institutes of Health researchers have identified a striking signature in tumor DNA that occurs in five different types of cancer. The specific signature results from a chemical modification of DNA called methylation, which can control the expression of genes like a dimmer on a light switch. Based on this advance, the researchers hope to spur development of a blood test that can be used to diagnose a variety of cancers at early stages.

Cancer treatment: Therapeutic approach gives hope for the treatment of multiple myeloma
A new therapeutic approach tested by a team from Maisonneuve-Rosemont Hospital and the University of Montreal gives promising results for the treatment of multiple myeloma, a cancer of the bone marrow currently considered incurable with conventional chemotherapy. The study resulted in a total cure rate of 41 percent, a record level using this strategy. Moreover, patients in complete remission six months after the allograft had a relapse-free survival rate of 60 percent.

Single-lesion biopsy may be insufficient to choose therapy targeting resistance mutations
When metastatic tumors driven by drug-targetable genetic mutations become resistant to a targeted therapy drug, the usual practice is to test a single metastatic lesion for new mutations that can guide the selection of next-line therapies. But this strategy may miss additional targetable mutations that arise in different metastases, a new study finds.
