Schizophrenia risk gene linked to cognitive deficits in mice

Researchers have discovered in mice how one of the few genes definitively linked to schizophrenia, called SETD1A, likely confers risk for the illness. Mice genetically engineered to lack a functioning version of the enzyme-coding gene showed abnormalities in working memory, mimicking those commonly seen in patients. Restoring the gene's function corrected the working memory deficit and counteracting its deficiency also repaired neuronal circuit deficits in adult mice — suggesting clues for potential treatment strategies.

Society is rejecting facts; medical researchers can help

Anecdotes, fake news and social media have created a skeptical and misinformed public who is rejecting the facts. A commentary says that medical researchers must help the public understand the rigorous process of science and help them to discern an anecdote from peer-reviewed scientific results. The best way to do this? By continuing to ensure integrity, rigor, reproducibility and replication of their science and to earn the public's trust by being morally responsible and completely free of any influences.

New insights into biological underpinnings of schizophrenia

Researchers have implicated 10 new genes in the development of schizophrenia using a method called whole exome sequencing, the analysis of the portion of DNA that codes for proteins. A global consortium of schizophrenia research teams incorporated genetic data from over 125,000 people to gain deeper insights into the genetic underpinnings of schizophrenia.

New target regulating mitochondria during stress

Like an emergency response team that is called into action to save lives, stress response proteins in the heart are activated during a heart attack to help prevent cell death. As part of this process, researchers show for the first time that one of these specialized emergency responder proteins, known as MCUB, temporarily decreases harmful levels of calcium transport into mitochondria, the energy-generating batteries of cells.

More operations are scheduled if doctor is well rested

Researchers have investigated how orthopedic surgeons make decisions regarding surgery, and how the decisions are related to how much of their work shift they have completed. The results show that a patient who meets the surgeon at the end of his or her shift is less likely to be scheduled for surgery.
