Abstract：
:The effect of gestational age on serum-mediated changes in enolase activity was tested in a fetal rat brain cell culture. After 6 days exposure to graded concentrations (10 and 20%) of nonpregnant female rat sera, enolase activity in brain cell cultures increased from 2.83 +/- 0.03 to 3.74 +/- 0.19 mumol/min/mg protein, P less than 0.01. By contrast, similar concentrations of 20-day maternal serum progressively decreased enzyme activity from 1.52 +/- 0.14 to 1.19 +/- 0.08 mumol/min/mg protein. The inhibitory effect was apparent at 14 days gestation and became progressively greater during late gestation to reach a maximum at 20 days. Combining equal concentrations of 20-day pregnant with either nonpregnant or adult male serum neutralized the inhibitory activity. When serum from 20-day pregnant rats was partitioned by a dialysis membrane with a 50,000 MW pore size, inhibitory activity could be similarly neutralized by male or nonpregnant female serum. When 20-day maternal serum was passed successively through filters with a greater than 300,000, 100,000, and 50,000 MW exclusion, the inhibitory activity was apparent in all fractions excluded by a molecular weight of 50,000. No inhibition was apparent in fractions that were not excluded by 50,000 MW pore size. Inhibition of enolase activity was greatest in the fraction with MW greater than 300,000. Binding of IGF II could also be demonstrated in this fraction. Binding of IGF II was evident in the fraction greater than 100,000 MW but could not be demonstrated in fractions with a lower molecular weight. The presence of mRNA for IGF II in 20-day fetal rat brain cell cultures was evident when total cellular RNA was analyzed by an RNAase protection assay. It is proposed that a high-molecular-weight component of maternal serum in late gestation can bind endogenously generated IGF II. Such binding, by depleting the necessary growth factors, could inhibit in vitro growth and development of enolase activity.
