“ Glucose (20 mM) caused a rapid breakdown of phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol 4-phosphate and an accumulation of inositol trisphosphate and inositol bisphosphate.”
“ D-Glucose decreased the amount of [32P]PO4 in phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2] and phosphatidylinositol 4-phosphate (PtdIns4P) within 0.5 min, and loss of radiolabel was still evident at 1 min.”
“Addition of glucose to glucose-deprived cells of the yeast Saccharomyces cerevisiae triggers rapid turnover of phosphatidylinositol, phosphatidylinositol-phosphate and phosphatidylinositol 4,5-bisphosphate.”
“Mutants which are defective for completion of cell cycle "START" (i.e. commitment to mitosis) show reduced formation of glycerophosphoinositol 4-phosphate and glycerophosphoinositol 4,5-bisphosphate in response to glucose.”
