"We want to be able to monitor our ability to open the blood-brain barrier in real-time by listening to echoes -- this could give us immediate information on the stability of the microbubbles oscillations and give us fast, real-time control and analysis," said lead author Tao Sun, a PhD candidate
Cancer is caused by changes in the human genome. Mutations in oncogenes and in tumor suppressor genes accumulate unrecognized over time and lead to uncontrolled cell proliferation eventually. In 50% of all human tumors the tumor suppressor gene TP53 is no longer functional being the most frequently mutated cancer gene.
But researchers have recently used T-cells engineered in the laboratory to combat tumours. Modified to include additional functions, these immune cells can hunt down and kill cancer cells. Unfortunately, however, such immune cell therapies can have significant side-effects. On top of that, the production of modified T-cells is technically challenging.
"Recent successes in cancer immunotherapy -- in the form of immune checkpoint inhibitors and adoptive T cell transfer -- demonstrate how activated immune cells can eradicate tumors, but until now we didn't fully appreciate immunosurveillance or the role of adaptive immunity in tumor formation," said senior author Michael Karin, PhD,
During an embryo's development, epithelial cells can break away from the cell cluster, modify their cell type-specific properties, and migrate into other regions to form the desired structures there. This process, which is known as an epithelial-mesenchymal transition (EMT), is reversible and can also proceed in the direction from mesenchymal
"Breast tumors are moving targets because they are really versatile," says Jun-Lin Guan, Francis Brunning Professor and Chair of the Department of Cancer at the University of Cincinnati College of Medicine and member of the Cincinnati Cancer Center and UC Cancer Institute, who co-authored the paper with postdoctoral fellow Syn
The researchers found that in B cell tumors, mutated overactive versions of the Notch protein directly drive the expression of the Myc gene and many other genes that participate in B cell signaling pathways. Myc is a critical gene in governing cell proliferation and survival, activities that it carries out
The findings come from a study in which researchers from Imperial College London used psilocybin -- the psychoactive compound that occurs naturally in magic mushrooms -- to treat a small number of patients with depression in whom conventional treatment had failed. In a paper, published today in the journal Scientific Reports, the
In the brain, LSD1 (lysine specific histone demethylase 1) maintains silence among genes that are supposed to be turned off. When the researchers engineered mice that have the LSD1 gene snipped out in adulthood, the mice became cognitively impaired and paralyzed. Plenty of neurons were dying in the brains of
"We literally watched people's brains drain fluid into these vessels," said Daniel S. Reich, M.D., Ph.D., senior investigator at the NIH's National Institute of Neurological Disorders and Stroke (NINDS) and the senior author of the study published online in eLife. "We hope that our results provide new insights to a variety
