BACKGROUND Mirror therapy has been demonstrated to reduce phantom limb pain (PLP) experienced by unilateral limb amputees. Research suggests that the visual feedback of observing a limb moving in the mirror is critical for therapeutic efficacy. OBJECTIVE Since mirror therapy is not an option for bilateral lower limb amputees, the purpose of this study was to determine if direct observation of...
The induction of ornithine decarboxylase (ODC) activity may be an essential component of skin tumor promotion. ODC requires pyridoxal 5'-phosphate (PLP) as a cofactor. We have measured the epidermal PLP concentration and investigated its relationship to DNA synthesis and ODC activity in the hairless mouse. The epidermal PLP concentration was approximately 1.0 microgram/g. When tape-stripping wa...
Background: The cuprizone multiple sclerosis (MS) animal model is characteristic for toxic demyelination and represents a reversible demyelination and remyelination system. It has been shown that green tea epigallocatechin-3-gallate (EGCG) might be effective in improving the symptoms and pathological conditions associated with autoimmune inflammatory diseases in several animal models. Object...
to understand the mechanism of multiple sclerosis (ms), an autoimmune demyelinating disease, the researchers developed an experimental animal model for ms, which is called eae (experimental allergic encephalomyelitis). there are several methods for inducing this animal model. in this research the active eae, which is developed by injecting bovine myelin antigens into genetically susceptible ani...
Aims: To study the effects of pyridoxal phosphate (PLP) on oxidative stress in isolated pancreatic acinar cells. We have previously shown that PLP has cytoprotective and insulinotropic effects on mice islet cells in vivo and in vitro studies. Main methods: Acinar cells were isolated from three months old WNIN male rats and were cultured in vitro for a period of 24 h in CO2 incubator. Later the ...
The biologically active form of vitamin B6, pyridoxal 5'-phosphate (PLP), is a cofactor in over 160 enzyme activities involved in a number of metabolic pathways, including neurotransmitter synthesis and degradation. In humans, PLP is recycled from food and from degraded PLP-dependent enzymes in a salvage pathway requiring the action of pyridoxal kinase, pyridoxine 5'-phosphate oxidase and phosp...
It is well known that chronic ethanol treatment affects the synthesis of RNA and protein in the brain and the maintenance and function of nervous system. The changes in myelination-related genes are most prominent in human alcoholics. Previously, our cDNA microarray study showed altered Proteolipid protein (PLP), a major protein of central myelin. The present study aimed to gain more understand...
Previously, we demonstrated that a placental hormone, PRL-like protein E, stimulates megakaryocyte growth and differentiation. We now find that PRL-like protein E and a second placental hormone, PRL-like protein F (PLP-F), bind the same receptor. PLP-F, which is produced later in pregnancy, might therefore act as either an agonist or antagonist of PRL-like protein E. To resolve this question, w...
Cofactors may be expected to expand the range of reactions amenable to antibody-assisted catalysis. The biological importance of pyridoxal 5'-phosphate (PLP) as enzymic cofactor in amino acid metabolism and its catalytic versatility make it an attractive candidate for the generation of cofactor-dependent abzymes. Here we report an efficient procedure to screen antibodies for PLP-dependent catal...
Many studies have suggested that the 3D organization of chromatin and proteins within the nucleus contributes to the regulation of gene expression. We tested multiple aspects of this nuclear organization model within a primary cell culture system. Oligodendrocyte lineage cells were examined to facilitate analysis of nuclear organization relative to a highly expressed tissue-specific gene, prote...
