Medical Xpress / Inflammation jolts 'sleeping' cancer cells awake, enabling them to multiply again
Cancer cells have one relentless goal: to grow and divide. While most stick together within the original tumor, some rogue cells break away to traverse to distant organs. There, they can lie dormant—undetectable and not ...
Medical Xpress / Activating brown fat may yield a new strategy to tackle obesity
Is it possible to treat obesity without reducing food intake? A new study co-led by Dr. Antonio Zorzano and Dr. Manuela Sánchez-Feutrie at the Institute for Research in Biomedicine (IRB Barcelona) suggests that this might ...
Medical Xpress / How brain fluid dynamics drive cancer spread—and ways to fight back
New research has uncovered how cerebrospinal fluid dynamics in the brain play an important role in driving the spread of medulloblastoma, the most common malignant brain tumor in children.
Medical Xpress / Gene variant slows down removal of debris in the brain, increasing Alzheimer's risk, say researchers
A type of brain cell that plays a vital role in maintaining neural networks and repairing injuries lies at the core of a promising new study on Alzheimer's disease from the USF Health Byrd Alzheimer's Center and Research ...
Medical Xpress / Dietary changes could provide a therapeutic avenue for brain cancer
Glioblastomas are the deadliest form of malignant brain tumor, and most patients diagnosed with the disease live only one or two years. In these tumors, normal cells in the brain become aggressive, growing rapidly and invading ...
Medical Xpress / Microscopic pores in brain cells may be key to understanding Parkinson's
A toxic protein forms dynamic pores in the membranes of brain cells—and that may be the key to understanding how Parkinson's disease develops. This is the conclusion of a new study from Aarhus University, where researchers ...
Medical Xpress / After early-life stress, astrocytes can affect behavior
Astrocytes in the lateral hypothalamus region of the brain, an area involved in the regulation of sleep and wakefulness, play a key role in neuron activity in mice and affect their behavior, Canadian researchers have found.
Medical Xpress / Study shows how smoking drives pancreatic cancer
A new study explains why smokers have a higher chance of developing pancreatic cancer and why they tend to have worse outcomes than nonsmokers.
Medical Xpress / Stem cell scientists unlock blueprint for lab-grown kidney cells with preclinical value
In the lab, it's easier to grow simple balls of cells than complex asymmetrical structures with two distinct ends—like the one million filtering units—nephrons—that make up a human kidney. But new research unveils a ...
Medical Xpress / Scientists look to commercial dyes to help them diagnose dementia
Today, when an aging parent, relative, or friend starts to forget things, a firm diagnosis can be surprisingly elusive.
Medical Xpress / How the Epstein-Barr virus hooks onto DNA to reorganize genome and drive nasopharyngeal cancer spread
Researchers from the University of Hong Kong have discovered that the Epstein-Barr virus (EBV), a common human virus closely linked to nasopharyngeal carcinoma (NPC), can change the 3D structure of the human genome inside ...
Medical Xpress / Squeezing through tiny blood vessels may trigger melanoma cells to spread
Nine of the 10 most common cancer deaths in Australia are caused by solid tumors, but in most cases it's the cancer's spread to other parts of the body—known as metastasis—that proves fatal.
