Photo: Image of brain [10/07/2015] Researchers at the University of California, San Diego and the School of Medicine have found that the three-dimensional shape of the cerebral cortex – the wrinkled outer layer of the brain controlling many functions of thinking and sensation – strongly correlates with ancestral background.Geometry of brain's outer surface correlates with genetic heritage - Read more

How intracellular signaling regulates growth factor production

Graphic: Cutting cells [10/07/2015] Now, researchers from German Leibniz Institute for Age Research (FLI) and Harvard University, US, showed that the factor-precursor-producing cells themselves determine if and when cleavage may occur. This is decided by intracellular signaling. Interfering with defined signaling in cells producing cancer growth factors could be developed into a new way of cancer treatment.How intracellular signaling regulates growth factor production - Read more

Disrupting cells' 'powerhouses' can lead to tumor growth

Photo: Cells [09/07/2015] Cancer cells defy the rules by which normal cells abide. They can divide without cease, invade distant tissues and consume glucose at abnormal rates. Now a study by University of Pennsylvania researchers implicates defects in mitochondria, the energy-production centers of cells, as playing a key role in the transition from normal to cancerous.Disrupting cells' 'powerhouses' can lead to tumor growth - Read more

Heart attack treatment hypothesis 'busted'

Photo: Man with heart attack [07/07/2015] Researchers have long had reason to hope that blocking the flow of calcium into the mitochondria of heart and brain cells could be one way to prevent damage caused by heart attacks and strokes. But in a study of mice engineered to lack a key calcium channel in their heart cells, Johns Hopkins scientists appear to have cast a shadow of doubt on that theory.Heart attack treatment hypothesis 'busted' - Read more

Photo: Histological section of two mouse melanomas [18/06/2015] Scientists at the Institut Pasteur and Inserm have successfully increased the infiltration of immune cells into tumors, thus inducing the immune system to block tumor growth. In an article published in Nature Immunology, the scientists show that, in combination with existing immunotherapies, this process efficiently destroys cancer cells.Restoring natural immunity against cancer - Read more

Mini-breast grown in petri dishes

Photo: Detail of breast epithelial cells [15/06/2015] About 70.000 women are diagnosed with breast cancer every year in Germany alone. Despite significant progress in the treatment of common types of breast cancer, some aggressive subtypes of the disease are poorly understood and remain incurable. A new experimental model opens new avenues for mammary gland biology and basic breast cancer research. Mini-breast grown in petri dishes - Read more

Microendoscope could eliminate unneeded biopsies

Photo: Cells in a biopsy sample under the microscope [02/06/2015] In a clinical study of patients in the United States and China, researchers found that a low-cost, portable, battery-powered microendoscope developed by Rice University bioengineers could eventually eliminate the need for costly biopsies for many patients undergoing standard endoscopic screening for esophageal cancer.Microendoscope could eliminate unneeded biopsies - Read more
