Two cyclooxygenase (COX) enzymes, COX-1 and COX-2, are present in human cells. While COX-1 is constitutively expressed, COX-2 is inducible and up-regulated in response to many signals. Since increased transcriptional activity accounts for only part of COX-2 up-regulation, we chose to explore other RNA processing mechanisms in the regulation of this gene.(More)
The U1 snRNP-A (U1A) protein has been known for many years as a component of the U1 snRNP. We have previously described a form of U1A present in human cells in significant amounts that is not associated with the U1 snRNP or U1 RNA but instead is part of a novel complex of non-snRNP proteins that we have termed snRNP-free U1A, or SF-A. Antibodies that(More)
The human MeCP2 gene encodes a ubiquitously expressed methyl CpG binding protein. Mutations in this gene cause a neurodevelopmental disorder called Rett Syndrome (RS). Mutations identified in the coding region of MeCP2 account for approximately 65% of all RS cases. However, 35% of all patients do not show mutations in the coding region of MeCP2, suggesting(More)
