Upregulation of immunoglobulin-related genes in cortical sections from multiple sclerosis patients.

Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS). Microarray-based global gene expression profiling is a promising method, used to study potential genes involved in the pathogenesis of the disease. In the present study, we have examined global gene expression in normal-appearing gray matter and gray matter lesions from the cortex of MS patients, and compared them with cortical gray matter samples from controls.

Identification of a copper-repressible C-type heme protein of Methylococcus capsulatus (Bath). A member of a novel group of the bacterial di-heme cytochrome c peroxidase family of proteins.

Genomic sequencing of the methanotrophic bacterium, Methylococcus capsulatus (Bath), revealed an open reading frame (MCA2590) immediately upstream of the previously described mopE gene (MCA2589). Sequence analyses of the deduced amino acid sequence demonstrated that the MCA2590-encoded protein shared significant, but restricted, sequence similarity to the bacterial di-heme cytochrome c peroxidase (BCCP) family of proteins. Two putative C-type heme-binding motifs were predicted, and confirmed by positive heme staining.
