Polyamines are essential for the stimulation of intestinal epithelial cell (IEC) migration during restitution in association with their ability to regulate Ca2+ homeostasis, but the exact mechanism by which polyamines induce cytosolic free Ca2+ concentration ([Ca2+]cyt) remains unclear. Phospholipase C (PLC)-gamma1 catalyzes the formation of inositol (1,4,5)-trisphosphate (IP3), which is implicated in the regulation of [Ca2+]cyt by modulating Ca2+ store mobilization and Ca2+ influx. The present study tested the hypothesis that polyamines are involved in PLC-gamma1 activity, regulating [Ca2+]cyt and cell migration after wounding. Depletion of cellular polyamines by alpha-difluoromethylornithine inhibited PLC-gamma1 expression in differentiated IECs (stable Cdx2-transfected IEC-6 cells), as indicated by substantial decreases in levels of PLC-gamma1 mRNA and protein and its enzyme product IP3. Polyamine-deficient cells also displayed decreased [Ca2+]cyt and inhibited cell migration. Decreased levels of PLC-gamma1 by treatment with U-73122 or transfection with short interfering RNA specifically targeting PLC-gamma1 also decreased IP3, reduced resting [Ca2+]cyt and Ca2+ influx after store depletion, and suppressed cell migration in control cells. In contrast, stimulation of PLC-gamma1 by 2,4,6-trimethyl-N-(meta-3-trifluoromethylphenyl)-benzenesulfonamide induced IP3, increased [Ca2+]cyt, and promoted cell migration in polyamine-deficient cells. These results indicate that polyamines are absolutely required for PLC-gamma1 expression in IECs and that polyamine-mediated PLC-gamma1 signaling stimulates cell migration during restitution as a result of increased [Ca2+]cyt."xsd:string |
