在丽蝇唾液腺中,5-羟色胺刺激[3 H]肌醇、[32 P]磷脂酰肌醇、磷脂酰肌醇4-磷酸和磷脂酰肌醇4,5-二磷酸的快速和持续损失。标记的肌醇磷酸相应增加。在Ca 2+的情况下,5-羟色胺刺激标记的磷脂酰肌醇4,5-二磷酸的快速但短暂的损失。到5分钟时,标记的磷脂酰肌醇4,5-二磷酸的量恢复到对照值。二价离子载体A23187刺激标记的磷脂酰肌醇4,5-二磷酸的损失,并增加标记的磷脂酰肌醇的量。在匀浆中,Ca 2+刺激磷脂酰肌醇4,5-二磷酸分解,但不是磷脂酰肌醇分解。这些结果表明,标记的磷脂酰肌醇和磷脂酰肌醇4,5-二磷酸的酶刺激的分解通过磷脂酶C发生,并且相对独立于细胞外Ca 2+。也有钙激活的磷脂酰肌醇4,5-二磷酸转化为磷脂酰肌醇。
In blowfly salivary glands, 5-hydroxytryptamine stimulated a rapid and sustained loss of [3H]inositol, [32P]phosphatidylinositol, phosphatidylinositol 4-phosphate, and phosphatidylinositol 4,5-bisphosphate. There was a corresponding increase in labeled inositol phosphates. In the absence of Ca2+, 5-hydroxytryptamine stimulated a rapid but transient loss of labeled phosphatidylinositol 4,5-bisphosphate. By 5 min, the amount of labeled phosphatidylinositol 4,5-bisphosphate recovered to control values. The divalent ionophore A23187 stimulated loss of labeled phosphatidylinositol 4,5-bisphosphate and increased the amount of labeled phosphatidylinositol. In homogenates, Ca2+ stimulated phosphatidylinositol 4,5-bisphosphate breakdown but not phosphatidylinositol breakdown. These results suggest that hormone-stimulated breakdown of labeled phosphatidylinositol and phosphatidylinositol 4,5-bisphosphate occurs through a phospholipase C and is relatively independent of extracellular Ca2+. There is also a Ca2+-activated conversion of phosphatidylinositol 4,5-bisphosphate to phosphatidylinositol.
