Nerou, E P, Riley, A M, Potter, B V, Taylor, C W

Synthetic analogues of inositol trisphosphate (IP(3)), all of which included structures equivalent to the 4,5-bisphosphate of (1,4,5)IP(3), were used to probe the recognition properties of rat...

Functional properties of Drosophila inositol trisphosphate receptors.

Swatton, J E, Morris, S A, Wissing, F, Taylor, C W

The functional properties of the only inositol trisphosphate (IP(3)) receptor subtype expressed in Drosophila were examined in permeabilized S2 cells. The IP(3) receptors of S2 cells bound...

Endogenous heavy metal ions perturb fura-2 measurements of basal and hormone-evoked Ca2+ signals.

Snitsarev, V A, McNulty, T J, Taylor, C W

Using the membrane-permeant chelator of heavy metal ions, N,N,N',N'-tetrakis(2-pyridylmethyl)ethylene diamine (TPEN), we demonstrate that in pancreatic acinar cells, hepatocytes, and a variety of...

Different mechanisms of decreased drug accumulation in doxorubicin and mitoxantrone resistant variants of the MCF7 human breast cancer cell line.

Taylor, C. W., Dalton, W. S., Parrish, P. R., Gleason, M. C., Bellamy, W. T., Thompson, F. H., ...

We selected two drug resistant variants of the MCF7 human breast cancer cell line by chronic in vitro exposure to doxorubicin (MCF7/D40 cell line) and mitoxantrone (MCF7/Mitox cell line),...
