Suicide is the 10th leading cause of death in the United States, claiming more than 44,000 people in the country every year, similar to the number of deaths caused by the opioid epidemic. Previous studies show that suicide tracks in families independent of the effects from a shared environment. Researchers at the University of Utah Health are using resources unique to the state to identify…
Hypotrichosis simplex leads to progressive hair loss already in childhood. A team of researchers led by human geneticists at the University Hospital of Bonn has now deciphered a new gene that is responsible for this rare form of hair loss. Changes in the LSS gene lead to impairment of an important enzyme that has a crucial function in cholesterol metabolism. The scientists now present their…
A deep neural network algorithm called BOTA uses bacterial genomes to identify unrecognized bacterial antigens.
The CRISPR genome editing technique promises to be a "transformative leap" in genetic engineering and therapy, affecting almost every area of medicine. That includes plastic surgery, with potential advances ranging from prevention of craniofacial malformations, to therapeutic skin grafts, to new types of rejection-free transplants, according to a paper in the November issue of Plastic…
How is the activity of all genes in cells of higher organisms interconnected? And how are the genetic "wiring diagrams" of the cells in complex tissues coordinated with each other? Scientists from the German Cancer Research Center (DKFZ), the European Molecular Biology Laboratory and the University of Heidelberg are now planning to investigate this in two model organisms, Drosophila and…
Scientists have uncovered the cause of Saul-Wilson syndrome: A single, spontaneous gene change alters protein packaging in the cell’s Golgi complex, causing the disease.
Historical bias is a key reason why biomedical researchers continue to study the same 10 percent of all human genes while ignoring many genes known to play roles in disease, according to a study led by Thomas Stoeger and Luís Amaral of Northwestern University, and colleagues. This bias is bolstered by research funding mechanisms and social forces.
A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells. Such a practice could help doctors identify patients at high risk of disease recurrence early after a transplant and help guide treatment decisions.
An international collaboration between Imperial College London, Singapore's Duke-NUS Medical School and Belgium-based pharmaceutical company UCB led to the discovery of a new anti-epileptic drug target and a whole new approach that promises to speed up the discovery of future drugs to treat debilitating diseases, such as epilepsy.
Clinicians should consider how the way we think can make us vulnerable to obesity, and how obesity is genetically intertwined with brain structure and mental performance, according to new research. The study, led by researchers at the Montreal Neurological Institute and Hospital (The Neuro), was an examination of MRI and cognitive test data from 1,200 individuals, supplied as part of the Human…
The genome sequences of ape parasites related to Plasmodium vivax (P. vivax), the main source of mosquito-borne malaria outside Africa, provide insights on the origin and early evolution of the human parasite. This finding could have implications for better comprehending and eradicating malaria infection worldwide.
It doesn’t often happen that army generals switch sides in the middle of a war, but when cancer is attacking, it may cause even a gene that acts as the body’s master defender to change allegiance. Researchers at the Weizmann Institute of Science have discovered that this gene’s betrayal can occur in more ways than previously appreciated – and might even return the renegade cells to their…
A scientist has discovered a gene-editing technology that could efficiently and accurately correct the genetic defects that underlie certain diseases, positioning the new tool as the basis for the next generation of genetic therapies.
The idea of testing blood or urine to find markers that help diagnose or treat disease holds great promise. A new study helps set standards for RNA sequencing, improving consistency and laying the foundation to move the field forward.
A team led by the University of California San Diego has developed a chip that can detect a type of genetic mutation known as a single nucleotide polymorphism (SNP) and send the results in real time to a smartphone, computer, or other electronic device. The chip is at least 1,000 times more sensitive at detecting an SNP than current technology. The advance could lead to cheaper, faster and…
CRISPR has recently become synonymous with precise genetic editing. However, the mighty tool has been known to fail from time to time. Now, researchers have found out why.
The exchange of a single amino acid building block in a metabolic enzyme can lead to cancer. In addition, it can impair the immune system. It thus blocks the body’s immune response in the battle against the mutant molecule and also impedes immunotherapy against brain cancer. This finding opens new insights into cancer development and progression and it also suggests that rethinking antitumor…
The fact that genetic research can reveal hereditary diseases has been transferred to medical practice for some time and, since 2010, the Gene Diagnostics Act (GenDG) has regulated permissible DNA tests in medical diagnostics and pedigree in Germany. The procedure has great potential, says Professor Jochen Taupitz - but also great risks are associated with it.
Australia's national science agency CSIRO has identified a new gene that plays a critical role in regulating the body's immune response to infection and disease.
Early whole genome sequencing might bring hope for children who are born severely ill or who develop serious illness in the first few weeks of their life. Because these children are often difficult to diagnose, detection of diseases has considerable implications for their short and longer-term care. At the annual conference of the European Society of Human Genetics (ESHG) in Milan, Italy, the…
Aging is a major risk factor for physical frailty and the development of age-related diseases such as cancer, cardiovascular diseases, type II diabetes and Alzheimer's disease. Numerous studies have already shown that a calorie-restricted diet can significantly delay age-related conditions in several organisms like flies, worms, fish and mice, and that it even improves fitness at old age. But who…
Cancer is a disease often driven by mutations in genes. As researchers learn more about these genes, and the proteins they code for, they are seeking smarter drugs to target them. The ultimate goal is to find ways to stop cancer cells from multiplying out of control, thereby blocking the growth and spread of tumors. Now researchers from The Scripps Research Institute are reporting an innovative…
The APOE gene, the strongest genetic risk factor for Alzheimer’s disease, may play a more prominent role in disease development among women than men, according to new research from the Vanderbilt Memory and Alzheimer’s Center. The research confirmed recent studies that carrying the APOE ε4 allele has a greater association with Alzheimer’s disease among women compared to men, and went one…
The digital audio of an entire music album is to be stored in the form of genetic information for the first time, using technology developed at ETH Zurich. Coded in DNA molecules and poured into tiny glass beads, an album by Massive Attack will be preserved – practically for eternity. The British band Massive Attack are considered pioneers of trip hop, an atmospheric style of electronic music…
A Vanderbilt team took the next leap forward in using a little-known bacteria to stop the spread of deadly mosquito-borne viruses such as Zika and dengue. Wolbachia are bacteria that occur widely in insects and, once they do, inhibit certain pathogenic viruses the insects carry. The problem with using Wolbachia broadly to protect humans is that the bacteria do not normally occur in mosquitoes…
