| abstractText | Although lipids compose almost 80% of myelin, the influence of quaking on mRNAs encoding lipid biosynthetic enzymes and transport proteins has not been previously reported. Understanding the influence of quaking on myelin-specific and lipid-related mRNAs will be useful in determining the mechanism of the quaking defect. Stearoyl CoA desaturase (SCD) catalyzes a key step in the biosynthesis of oleic acid (C18:1, n-9), a major fatty acid in myelin. SCD, LDL receptor (LDLR) and apolipoprotein E (Apo E) mRNA levels are all reduced in neonatal quaking brains. In contrast to brain, quaking hepatic LDLR and Apo E mRNA levels are normal. These results indicate that lipid-related mRNAs are reduced in neonatal quaking brain, but the quaking liver is unaffected. The quaking defect influences gene expression in multiple cell types of glial lineage in the developing CNS. |
