Medicine & Health news
Largest ever genome-wide study strengthens genetic link to obesityThere are many reasons why people gain different amounts of weight and why fat becomes stored in different parts of their bodies. Now researchers are homing in on genetic reasons. Their findings, part of the largest genome-wide study to date, were published in two companion papers today in the journal Nature. | |
One-two punch catches cancer cells in vulnerable stateTiming may be decisive when it comes to overcoming cancer's ability to evade treatment. By hitting breast cancer cells with a targeted therapeutic immediately after chemotherapy, researchers from Brigham and Women's Hospital (BWH) were able to target cancer cells during a transitional stage when they were most vulnerable, killing cells and shrinking tumors in the lab and in pre-clinical models. The team reports its findings in Nature Communications on February 11. | |
Researchers uncover signal that switches cells to cancerous metabolismAbnormal metabolism within the cells is a distinctive characteristic of cancer, but until now, the mechanism that causes cells to undergo this metabolic shift remained unknown. | |
Real-time brain feedback reduces attention lapsesYour attention, please. People make mistakes every day because they lose focus. Maybe your car drifts across the center line or an error slips into a report at work. | |
Why the wheels come off in communicationHow can two people come up with two completely different Lego models while working from the same instructions? | |
Brain's GPS system influenced by shape of environmentPatterns created by the brain's grid cells, which are believed to guide navigation, are modified by the shape of the environment, according to UCL researchers. This means grid patterns aren't a universal metric for the brain's GPS system to measure distance, as previously thought. | |
Mutation detection in human in vitro fertilized embryos using whole-genome sequencingPre-implantation genetic diagnosis (PGD) is used in fertility clinics to detect large chromosomal abnormalities or genetic mutations passed on by parents to their in vitro fertilized (IVF) embryos. However, it is not possible to comprehensively scan the embryo's genome to detect spontaneous mutations. In a study published online today in Genome Research, scientists developed a whole-genome sequencing approach using 5- to 10-cell biopsies from human embryos to detect potential disease-causing mutations. | |
Protein controls both alcohol craving and organ damageWhat if there was a drug that could simultaneously curb a person's craving for alcohol while also protecting their heart and liver from alcohol's damaging effects? While an actual pill that can do this might be a ways off, the results of a new study from researchers at the University of Iowa suggest that it might be potentially possible. | |
Revolutionary new probe zooms in on cancer cellsBrain cancer patients may live longer thanks to a new cancer-detection method developed by researchers at the Montreal Neurological Institute and Hospital - The Neuro, at McGill University and the MUHC, and Polytechnique Montréal.

Lab creates potentially life saving heart cellsA group of Simon Fraser University researchers' cultivation of dozens of beating heart cells in Petrie dishes could one day save or improve the lives of patients with inherited heart arrhythmias. They are genetic mutations that cause irregular heartbeats that can be lethal. | |
New strategic approach against bowel cancerColorectal carcinoma is the most frequent type of bowel cancer and the second most common tumour disease among men and women in Germany. So-called microsatellite stable colorectal cancer with mutations in the BRAF gene represents a particularly aggressive form. The BRAF gene produces the enzyme B-Raf, which plays a critical role in controlling cell division. A team of researchers from Freiburg and Stuttgart including the Freiburg biologists Dr. Ricarda Herr and Dr. Tilman Brummer analysed the effect of B-Raf inhibitors on the behaviour of colorectal cancer cells in three-dimensional tissue culture. Their findings show that B-Raf inhibitors cause the cancer cells to differentiate into cells that are characterised by more mature features and specialised to fulfil a specific function. Importantly, more differentiated cells often display a less aggressive behaviour. Hence, combination strategies, which are currently in clinical trials! and involve B-Raf inhibitors, might be able to prevent the cancer from spreading to other parts of the body. | |
Taking too much folic acid while pregnant may put daughters at risk of diabetes and obesityMothers that take excessive amounts of folic acid during pregnancy may predispose their daughters to diabetes and obesity later in life, according to a new study published today in the Journal of Endocrinology.

Transcriptomics identifies genes and signaling pathways that may regulate neurodegenerationNeuronal death is a normal feature of brain development but also a defining feature of neurodegenerative diseases when improperly regulated. Results of a detailed and comprehensive analysis of transcriptome expression alterations during neuronal death have been reported. A large number of genes previously not linked to neuronal death were identified in the study. Although further functional analyses are needed, some of these genes may be important players in the regulation of neuronal death and represent potential targets for the development of novel therapies. | |
Early retina cell changes in glaucoma identifiedGlaucoma, the second leading cause of blindness, usually stems from elevated eye pressure, which in turn damages and destroys specialized neurons in the eye known as retinal ganglion cells. To better understand these cellular changes and how they influence the progression and severity of glaucoma, researchers at University of California, San Diego School of Medicine and Shiley Eye Institute turned to a mouse model of the disease. Their study, published Feb. 10 in The Journal of Neuroscience, reveals how some types of retinal ganglion cells alter their structures within seven days of elevated eye pressure, while others do not. | |
Researchers identify novel factor involved in autophagyNeurodegenerative disorders such as Alzheimer's disease are typically characterized by protein deposits in the brain. These are comprised of defective, insoluble proteins which no longer fulfill their function and which cells are unable to break down. The work group headed by Professor Christian Behl of the Institute of Pathobiochemistry of the University Medical Center of Johannes Gutenberg University Mainz has determined the RAB3GAP complex as a novel factor that influences the efficient degradation of proteins. The researchers were able to show that the complex plays an important role in autophagy, a physiological process that breaks down cellular proteins and organelles. This insight opens up possible new options for the development of therapeutic and preventative approaches for neurodegenerative diseases. The work group has published the results of their research in the specialized journal Autophagy. | |
Bacteria protect intestinal tumor model from being killed by immune cellsBacteria that are commonly found in the mouth are often abundant in patients with colon cancer, but the potential role these microbes play in tumor development has not been clear.

Fujitsu develops technology to accurately align nodules within CT scan images taken over timeFujitsu today announced that it has developed a technology for the highly precise alignment of nodules, or growths of cells, within computed tomography (CT) images taken of the same patient on different dates. In CT imaging, the position of a nodule may change because of a person's heartbeat and breathing. In the past, these images have been aligned using surrounding blood vessels and other features as reference points, but when there are few blood vessels in close proximity, this technique is imprecise. Fujitsu has now developed a technology that very accurately aligns these images using not only nearby blood vessels, but also those located over a larger area as reference points, even when there are few blood vessels nearby. | |
