  • In zebrafish mutants in which a particular BMP protein is functionally reduced, there was a resulting increase in Lim1+ interneurons (medial interneurons) post-mitotically (Nguyen et al. (bartleby.com)
  • In the precursors, they discovered high numbers of a protein called Nup153, which is part of a multiprotein complex that forms a gatekeeping pore in the nuclear membrane, controlling what goes in or out. (neurosciencenews.com)
  • His interests in neurosurgery include endovascular techniques and traumatic brain injury. (rochester.edu)
  • Recent research in several laboratories has linked breakdown of protein homeostasis to declining cell function. (sciencedaily.com)
  • To function, each living cell needs both to build new and to degrade old or damaged proteins. (science20.com)
  • We determined how to enhance UPS function and influence catalytic protein degradation and cell survival in HD. (science20.com)

  • Our laboratory conducts cerebrovascular research to better understand brain physiology and function in neurological disorders (e.g., epilepsy and epilepsy with other comorbidities such as stroke or depression), with a focus on the blood-brain barrier. (ccf.org)
  • By regulating certain genes and proteins, the hnRNP K protein plays a role in the normal development and function of several body systems, including the brain. (medlineplus.gov)
  • Huntingtin contains a few domains that suggest particular functions, including WW domains and caspase cleavage sites ( 7 , 8 ), but the function of the protein remains unknown. (jci.org)
  • Future studies of MeCP2 promise to shed light upon brain function, neurological disease and the biology of DNA methylation. (portlandpress.com)
