In order to reduce severely the maternal glucose supply to the fetuses in short-term experiments, we have combined phloridzin administration to pregnant rats with 18 h starvation. Fetuses from starved phloridzin-treated mothers were compared with fetuses from starved mothers. Combined treatment markedly decreases fetal blood glucose concentration (-36%) and fetal liver glycogen stores (-76%). These changes are associated with a decrease in plasma insulin (-25%), a rise in plasma glucagon (+120%) and a marked increase of hepatic PEPCK activity (+400%). It appears from these results that phloridzin treatment for a short duration is able to induce glycogenolysis and the premature appearance of PEPCK in the liver of rat fetuses. | lld:pubmed |
