Calmodulin and calmodulin-dependent mechanisms are probably important in regulating thyroid cell function. However, calmodulin antagonists may directly modify calcium fluxes in cells. In the present investigation the effects of several calmodulin inh

Stimulating rat thyroid FRTL-5 cells with the purinergic agonist ATP activates both the inositol phosphate signal-transduction pathway and the phospholipase A2 pathway. In the present study we wanted to investigate the possible inter-relationships be

The expression of the P2 receptors and their functional responses were studied in rat thyroid FRTL-5 cells. RT-PCR analysis revealed transcripts for the G protein-coupled P2Y(2), P2Y(4) and P2Y(6) receptors, and for the transmitter-gated ion channel

We investigated the mechanism of phospholipase A(2) (PLA(2)) activation in response to the P2 receptor agonist ATP in rat thyroid FRTL-5 cells. The PLA(2) activity was determined by measuring the release of [(3)H]-arachidonic acid (AA) from prelabele

We examined the importance of tyrosine kinase(s) on the ATP-evoked Ca2+ entry and DNA synthesis of thyroid FRTL-5 cells. ATP rapidly and transiently tyrosine phosphorylated a 72-kDa protein(s). This phosphorylation was abolished by pertussis toxin an

Several growth factors may stimulate proliferation of thyroid cells. This effect has, in part, been dependent on calcium entry. In the present study using FRTL-5 cells, we show that in addition to its effect on calcium fluxes, ATP acts as a comitogen

Receptor-mediated calcium entry was investigated in Fura 2 loaded FRTL-5 cells. The purinergic agonist ATP activated the release of sequestered calcium and the entry of extracellular calcium. Downregulation of protein kinase C (PKC) substantially enh

Stimulating rat thyroid FRTL-5 cells with agonists that activate the inositol phosphate cascade results in the release of sequestered calcium and influx of extracellular calcium. In addition, phospholipase A2 (PLA2) is activated. Since PLA2 is a calc

In the present investigation, intracellular sodium ([Na+]i) levels were determined in GH4C1 cells using the fluorescent probe SBFI. Fluorescence was determined by excitation at 340 nm and 385 nm, and emission was measured at 500 nm. Intracellular fre
