Loss of gene leads to protein splicing and buildup of toxic proteins in neurons
JACKSONVILLE, Fla. -- Researchers at Mayo Clinic in Jacksonville have discovered how loss of a gene can lead to accumulation of toxic proteins in the brain, resulting in a common dementia, and they say this mechanism may be important in a number of age-related neurological disorders. In the S...Alternative Splicing in Neuronal Development
In the July 1st issue of G&D, Dr. Douglas Black (UCLA) and colleagues detail how alternative splicing is reprogrammed during neuronal development. Alternative splicing refers to the processing of an RNA transcript into different mRNA molecules by including some exons and excluding others. Spe...Alternative Splicing - Molecular Cloning
Alternative splicing is a molecular processwhich enables multiple genes to be produced from a single gene.
