Aggression in Childhood: Rooted in Genetics, Influenced by the Environment

According to a new psychosocial study, reactive and proactive types of aggressive behaviour in 6-year-old children share most of the same genetic factors. However, their evolution over time seems to be influenced by various environmental factors, suggesting the need to develop different intervention methods.

The scientists hope understanding how immune cells adapt as they enter different tissues will spur the design of better, more specific, medicines.

FDA Approves Gene Therapy for Inherited Blindness Developed by the University of Pennsylvania and Children’s Hospital of Philadelphia

In a historic move, the U.S. Food and Drug Administration (FDA) today approved a gene therapy initially developed by researchers at the University of Pennsylvania and Children’s Hospital of Philadelphia (CHOP) for the treatment of a rare, inherited form of retinal blindness. The decision marks the nation’s first gene therapy approved for the treatment of a genetic disease, and the first in which a new, corrective gene is injected directly into a patient.

New Measurements to Guide Radiation Therapy

When ionizing radiation passes through living tissue, it interacts with molecules present in the cells, stripping away electrons and producing charged species known as ions. Ionizing radiation used for cancer treatment includes gamma rays, X-rays and energetic particles. The electrons produced by this process, known as secondary electrons, can themselves go on to wreak further havoc, causing even more dramatic changes. This week in The Journal of Chemical Physics, investigators report studies of the impact of secondary electrons on a model of DNA.

Researchers Isolate Biting, Non-Biting Genes in Pitcher Plant Mosquitoes

Understanding that divergence, University of Notre Dame researchers say, is a starting point to determining whether there are non-biting genes in other species that could be manipulated in order to reduce transmission of vector-borne diseases.

The Not So Sweet Side of Christmas

A new video by the University of Warwick highlights a bitter side to our sugar consumption at Christmas. The short film highlights how excessive consumption of sugar can affect our health – and how the sugar trade in the past and today has caused inequality and bloodshed.Today Britons eat too much sugar, on average 10 per cent of our daily calories come from sugar which is equivalent to 60 g per day; however WHO guidelines state that adults should eat no more than of 30g of sugar a day which is just five per cent of our daily calorific intake.

Study Sheds Light on Rarity of Disease-Causing IGF Mutations

Peter Rotwein, M.D., was recently spotlighted by the American Society for Biochemistry and Molecular Biology (ASBMB) for a study he conducted on insulin-like growth factors (IGFs), a family of proteins that are crucial in early human growth and development. IGF mutations have been tied to dire health problems, like growth failure, intellectual deficiencies, and other developmental abnormalities.

Molecular Signature of “Trailblazer” Neural Crest Cells Gives Insight Into Development and Cancer

SIMR_Press_Release_14Dec_2017_PMK.jpg

In a study published online in the journal eLife, the researchers identified a molecular signature of approximately 1300 genes differentially expressed in an aggressive subset of migrating neural crest cells termed as “trailblazers” in a vertebrate model system of development. These genes appear to play a critical role in migration and may be part of a broader molecular signature of cell invasion in a number of phenomena.
