مستخلص: | During neonatal maturation of rat brain, a similar biphasic relationship exists between the previously reported pattern of glucose utilization and levels of each type of 6-phosphofructo-1-kinase (PFK) subunit protein, relative synthesis, and mRNA. The increasing amounts of each subunit isoform generally correlated with elevated protein synthesis which was promoted by greater amounts of each type of subunit mRNA. For each parameter, the early phase, 1 to 10 days after birth, was characterized by small increases, and the subsequent period from ten to thirty days postpartum was characterized by a much greater rate of increase. By 30 days after birth, adult values were observed. The apparent efficiency of translation of each type of PFK subunit mRNA in brain suggests that the M-type subunit mRNA is the most efficient and that the L-type subunit mRNA is the least. The greatest relative increases in subunit protein, mRNA, and synthesis were observed for the C-type subunit. Since enhanced translation apparently makes little, if any, contribution, a possible explanation of these phenomena could be increased transcription of the PFK genes. These neonatal changes could involve age-dependent alteration of methylation of the PFK gene promotor(s) and/or activity of effectors of the transcription of the PFK genes. |
