Studying the movement of tiny cells is no small task. For chromatin, the group of DNA, RNA, and protein macromolecules packed within our genome, motion is an integral part of its active role as a regulator of how our genes get expressed or repressed. “Understanding macromolecular motion is critical, but scientists know very little about
The origin of certain cancers in the sarcoma group is associated with a hitherto unknown interaction among different proteins. Findings now being presented create the opportunity to test new treatments of these forms of sarcoma. “We now know which mechanisms to shine the spotlight on,” says Pierre Åman, Professor of Tumor Biology at Sahlgrenska Academy,
Researchers at the University of Minnesota have developed a unique 3D-printed transparent skull implant for mice that provides an opportunity to watch activity of the entire brain surface in real time. The device allows fundamental brain research that could provide new insight for human brain conditions such as concussions, Alzheimer’s and Parkinson’s disease. The research
What makes a biological clock tick? According to a new study from U of T Mississauga, the surprising answer lies with a gene typically associated with stem and cancer cells. In the first study of its kind for the field of circadian biology, UTM researchers used RNA sequencing to observe the expression of genes in
Scientists at Scripps Research have found that they can reverse the desire to drink in alcohol-dependent rats — with the flip of a switch. The researchers were able to use lasers to temporarily inactivate a specific neuronal population, reversing alcohol-seeking behavior and even reducing the physical symptoms of withdrawal. “This discovery is exciting — it
Using strong and targeted but noninvasive magnets at specific sites in the brains of people with and without mild learning and memory problems, Johns Hopkins researchers report they were able to detect differences in the concentrations of brain chemicals that transmit messages between neurons. The strength of these magnetic fields allows the researchers to measure
Elizabeth Delacruz can’t crawl or toddle around like most youngsters nearing their second birthday. A rare metabolic disorder that decimated her mobility has also led to cortical blindness — her brain is unable to process images received from an otherwise healthy set of brown eyes. And multiple times a day Elizabeth suffers seizures that continually
Cleveland: Despite rapid advances in targeted therapies for cancer, tumors commonly develop resistance to treatment. When resistance emerges, tumor cells continue to grow unchecked, despite all attempts to slow cancer progression. While mutations in cancer cells significantly affect drug sensitivity, it is increasingly recognized that ecological interactions between cells can also play a role. Jacob
When a person takes a puff on a cigarette, nicotine floods into the brain, latching onto receptors on the surface of neurons and producing feelings of happiness. But nicotine does not simply stay on the surface of cells — the drug actually permeates into neural cells and alters them from the inside out. Now, a
Binge drinking in adolescence has been shown to have lasting effects on the wiring of the brain and is associated with increased risk for psychological problems and alcohol use disorder later in life. Now, researchers at the University of Illinois at Chicago Center for Alcohol Research in Epigenetics have shown that some of these lasting
A team of researchers under the direction of the Medical Center — University of Freiburg has succeeded in demonstrating in an animal model that previously entirely unknown types of immune cells are present in the inflamed brain in the course of multiple sclerosis (MS). The discovery was made by means of a new, high-resolution method
A North Carolina woman who was given a week to live after being diagnosed with an aggressive brain tumor says a new drug is the reason she’s still alive eight months later. Amanda Thomas, 30, wasn’t feeling well after a minor car wreck last November, and her mom worried she might have a concussion. But
Cardiff University researchers have uncovered new information about the underlying mechanisms for gastric cancer, providing hope of potential new therapies in the future. The team, at the University’s European Cancer Stem Cell Research Institute, found they could stop gastric cells dividing and growing by deleting a particular cell-surface receptor implicated in the function of stem
A new Tel Aviv University study finds that eosinophils — white blood cells that may have played an evolutionary role in combating parasites, but which are today responsible for chronic asthma and modern allergies — may be used to eliminate malignant colon cancer cells. The research was led by Prof. Ariel Munitz of the Department
Scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered that squamous cell skin cancers do not require increased glucose to power their development and growth, contrary to a long-held belief about cancer metabolism. The findings could bring about a better understanding of many cancers’ metabolic
Getting enough of the omega 3 fatty acids DHA and EPA into the brain to study their effects on conditions such as Alzheimer’s and depression — which they have been shown to help — is no easy task. While supplements containing these fatty acids exist, there is scant evidence showing that these supplements actually increase
Researchers at Sahlgrenska Academy at the University of Gothenburg, Sweden, in collaboration with research groups in Finland, Canada, and Slovenia, have discovered a novel and unexpected function of nestin, the best known marker of neural stem cells. In the developing brain, the 3 main cell types, specifically neurons, astrocytes and oligodendrocytes, are generated from neural
Scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have now found a cause for the frequent catastrophic events in the genetic material of cancer cells that have only been known for a few years: If an important DNA repair system of the cells has failed, this promotes fragmentation and defective assembly of the
Researchers at The University of Texas at Arlington have found a potential new pathway to regulate immune response and potentially control inflammatory diseases of the central nervous system such as meningitis and sepsis. “We need to know what turns on inflammatory response to bacterial infection to be able to modulate the process,” said Subhrangsu Mandal,
Researchers from the Netherlands Institute for Neuroscience and Amsterdam UMC have disclosed the nature of how T cells protect the brain against harmful viruses. The results of the study, which are published in Nature Communications, are important for investigating the role of the immune system in numerous brain disorders. Immune system The immune system protects
