title: Incorporation of inositol into the phosphoinositides of lymphoblastoid cell lines established from bipolar manic-depressive patients.
abstract: Lymphoblastoid cell lines established from patients suffering from bipolar manic-depressive psychosis or from a control group have been used to study the metabolism of the polyphosphoinositides in these cells. Cells were incubated for up to 6 h in [3H]inositol and the extent of inositol incorporation into the mono-, di- and triphosphoinositides was measured after extracting the water- and lipid-soluble inositol-containing pools. Although both the uptake of inositol and the 'free' intracellular inositol pool sizes were similar in the two cell groups, the incorporation of [3H]inositol into the phosphoinositides of the cells derived from bipolar manic-depressives was significantly less (by around 50-60%) than that which occurred in the control cells.
