In a new study from the Intermountain Healthcare Heart Institute in Salt Lake City, researchers have identified eight new gene mutations that may cause or contribute to idiopathic dilated cardiomyopathy, a form of heart disease not caused by known external influences, such as high blood pressure, obesity, smoking, or diseased coronary arteries.
Australian researchers have used hepatitis B virus genome sequences to deduce that the mainland Aboriginal population separated from other early humans at least 59,000 years ago.
A research group led by Professor GUO Yalong from the Institute of Botany of the Chinese Academy of Sciences, together with SONG Ge, and Sureshkumar Balasubramanian from the School of Biological Sciences, Monash University, Australia, has revealed that transposable element insertions could potentially help species with limited genetic variation adapt to novel environments.
Researchers from the University of Copenhagen have discovered autoreactive cells in persons suffering from narcolepsy. This is a new, important proof that the sleep disorder is an autoimmune disease. This knowledge may lead to better treatment of the chronic condition, the researchers behind the new discovery believe.
A human's health is shaped both by environmental factors and the body's interactions with the microbiome, particularly in the gut. Genome sequences are critical for characterizing individual microbes and understanding their functional roles. However, previous studies have estimated that only 50 percent of species in the gut microbiome have a sequenced genome, in part because many species have not yet been cultivated for study.
It has been known for decades that cancer cells have an altered metabolism and it is seen in several biochemical pathways and in particular, in the way they get energy for their survival. Now, a new article describes an epigenetic injury found in human tumours which created this altered path to take energy from the cancer.
Led by Assistant Professor of Organismic and Evolutionary Biology Mansi Srivastava, a team of researchers is shedding new light on how animals perform whole-body regeneration, and uncovered a number of DNA switches that appear to control genes used in the process.
For the first time, researchers unveil the genome of ito-mozuku (Nemacystus decipiens), the popular Japanese brown seaweed, providing data that could help farmers better grow the health food.
Physician-scientists in the Cancer Center at Children's Hospital of Philadelphia have developed a preclinical, potent therapy attached to an antibody that targets a surface protein expressed in most childhood neuroblastomas, effectively killing cancer cells.
In a new study, researchers at the University of Copenhagen show that the development of a certain type of immature stem cells -- also known as progenitor cells -- depends on the quantity of a special protein and interaction with other cells in the body. The new study has just been published in the scientific journal Developmental Cell.
