New imaging technique reveals ‘burst’ of activity before cell death: Novel dual-PWS platform reveals connections between macromolecular structure and dynamic movement in the chromatin within eukaryotic cells

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

Breakthrough in knowledge of how some sarcomas arise

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,

3D-printed transparent skull provides a window to the brain: Device could provide new insight for brain research on concussions, Alzheimer’s and Parkinson’s

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

‘Master pacemaker’ for biological clocks identified

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 hunt down the brain circuit responsible for alcohol cravings: Study may open the door to developing drug therapies or even gene therapies for alcohol addiction

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

EEG helps scientists predict epileptic seizures minutes in advance: Prevention: Edible acid can stabilize misfiring neurons

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

Advancing therapy by measuring the ‘games’ cancer cells play

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

New target for gastric cancer therapies: Researchers shed light on development of gastric cancer

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

White blood cells related to allergies may also be harnessed to destroy cancer cells: Eosinophil immune cells are capable of killing colon cancer cells, researchers say

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

Technique boosts omega 3 fatty acid levels in brain 100 fold

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

Defective DNA damage repair leads to chaos in the genome

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

Nature of immune cells in the human brain disclosed

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
