Researchers discover rare form of liver cancer in Mice

Heidelberg [Germany], August 19 (ANI): The cell of origin of mixed liver/biliary duct carcinomas, a rare type of liver cancer, has been found in mice by researchers from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Hebrew University in Jerusalem. Carcinogenesis has been linked to the pro-inflammatory immunological messenger interleukin 6 (IL-6). In mice, blocking IL-6 lowered the number and size of tumours.

Researchers reveal that deformation mechanics may be key in cancer fight

Washington [US], August 19 (ANI): A team has uncovered surprising mechanical behaviors of the nucleus. For years, the nucleus within a cell was thought to be elastic like a rubber ball, deforming and snapping back into shape as the cell navigated through pores and between fibers inside the human body. Researchers have now discovered that the nucleus is more complex than originally believed, behaving more like a liquid drop than a rubber ball.

Researchers find new functions for blood-brain barrier in neuron function and damage

Washington [US], August 17 (ANI): Researchers have made a surprising discovery linking Delta/Notch signalling in subperineurial glia (SPG) to the regulation of nerve ensheathment and neurotransmitter release at the Drosophila neuromuscular junction (NMJ). SPG, the counterpart of the endothelial layer in the vertebrate blood-brain barrier, form the key cellular layer that is critical for axonal ensheathment and the blood-brain barrier in Drosophila. The results provide mechanistic insight into the biology of barrier function and glia-neuron interactions.

Study reveals how brain gathers threat cues, turns them into fear

Washington [US], August 16 (ANI): Scientists at the Salk Institute have discovered a biochemical route that combines hazardous sights, sounds, and odours into a single message: Be afraid. CGRP is a protein that allows neurons in two different parts of the brain to combine hazardous sensory cues into a cohesive signal, label it as negative, and send it to the amygdala, which converts the information into fear.
