Oct 1, 2013 by News Staff

A team of scientists led by Dr Peter Fraser from the Babraham Institute in Cambridge, UK, has developed a new method to determine the 3D structures of chromosomes in single cells. This image shows a structural model of a chromosome from a white blood cell. Image credit: University of Cambridge. The commonly illustrated X-shape chromosome structure is only present when the cell divides. Dr Fraser and his colleagues have been able to model the structure...

Roles of Neuregulin 1 in neural development. NRG1 is released from neurons to promote the formation and maintenance of radial glial cells. Tangential migration of γ-aminobutyric acid-ergic interneurons requires NRG1 in the cortical region. Myelination and ensheathment of peripheral nerves are controlled by the amounts of NRG1 produced in substrate axons. NRG1 from axons might regulate oligodendrocyte development and myelination of axons in the CNS. NRG1 is also necessary for the formation of neuromuscular junctions - NMJs. NRG1 stimulates CNS synapse formation (Lin Mei & Wen-Cheng Xiong, 2008)
