Abstractdc.description.abstractPeroxisomal proliferator-activated receptors (PPAR) are a FA-response system involved in diverse cellular responses. FA regulate PPAR activity and modulate PPAR mRNA abundance. Increasing evidence indicates that PUFA are required for optimal neuronal development and function. To gain insight into the mechanism for nutrition-induced impairment of neuronal development and function we investigated the effect of chronic n-3 FA deficiency on PPAR mRNA levels in rat brain and ocular tissues. Rats were fed for three generations a diet designed to reduce DHA levels in tissues, and the abundance of PPARalpha and PPARbeta transcripts was measured by hybridization with specific probes. Chronic consumption of the alpha-linolenic acid (LNA)-insufficient diet caused a remarkable modification in DHA content in membrane phospholipids. The results reported here indicate that PPARalpha mRNA levels did not exhibit significant variation in ocular, hepatic, or nervous tissues from rats fed the experimental diet, In contrast, PPARbeta mRNA normalized to beta-actin mRNA was 21% higher in ocular tissue from F3 generation rats consuming the LNA-deficient diet but was independent of diet in hepatic and nervous tissues. The absolute abundance of PPARbeta transcripts shoved a 17% increase in ocular tissue from rats consuming the LNA-deficient diet (F3 generation). The biological significance of the reported changes in PPARbeta mRNA in ocular tissue remains to be determined.en_US
