Coccoid and spiral Helicobacter pylori differ in their abilities to adhere to gastric epithelial cells and induce interleukin-8 secretion.

Cole, S P, Cirillo, D, Kagnoff, M F, Guiney, D G, Eckmann, L

Helicobacter pylori exists as an actively dividing spiral form and a nonculturable, but viable, metabolizing coccoid form. Both forms are present in the stomach, but their relative pathophysiologic...

The mobilization regions of two integrated Bacteroides elements, NBU1 and NBU2, have only a single mobilization protein and may be on a cassette.

Li, L Y, Shoemaker, N B, Wang, G R, Cole, S P, Hashimoto, M K, Wang, J, ...

Bacteroides conjugative transposons can act in trans to excise, circularize, and transfer unlinked integrated elements called NBUs (for nonreplicating Bacteroides units). Previously, we localized and...

Site-directed mutations in the relaxase operon of RP4.

Cole, S P, Lanka, E, Guiney, D G

Mutations were constructed by site-directed mutagenesis in the relaxase operon of the broad-host-range plasmid RP4. The mutations were constructed in smaller plasmids, recombined into the 60-kb RP4...

Characterization of the gene for a protein kinase which phosphorylates the sporulation-regulatory proteins Spo0A and Spo0F of Bacillus subtilis.

Perego, M, Cole, S P, Burbulys, D, Trach, K, Hoch, J A

The kinA (spoIIJ) locus contains a single gene which codes for a protein of 69,170 daltons showing strong homology to the transmitter kinases of two component regulatory systems. The purified kinase...

A multidrug-resistance protein (MRP)-like transmembrane pump is highly expressed by resting murine T helper (Th) 2, but not Th1 cells, and is induced to equal expression levels in Th1 and Th2 cells after antigenic stimulation in vivo.

Lohoff, M, Prechtl, S, Sommer, F, Roellinghoff, M, Schmitt, E, Gradehandt, G, ...

A transmembrane pump for organic anions was identified in resting murine T helper (Th) 2, but not Th1 lymphocyte cell clones, as revealed by extrusion of a fluorescent dye. Dye extrusion inhibition...

ATP-dependent glutathione disulphide transport mediated by the MRP gene-encoded conjugate export pump.

Leier, I, Jedlitschky, G, Buchholz, U, Center, M, Cole, S P, Deeley, R G, ...

We have previously shown that the multidrug resistance protein (MRP) mediates the ATP-dependent membrane transport of the endogenous glutathione conjugate leukotriene C4 (LTC4) and of structurally...

Do glutathione and related enzymes play a role in drug resistance in small cell lung cancer cell lines?

Campling, B. G., Baer, K., Baker, H. M., Lam, Y. M., Cole, S. P.

Small cell lung cancer (SCLC) is treated primarily with combination chemotherapy. Despite high initial response rates, most patients eventually die with drug resistant disease. In some tumours,...

Chemosensitivity testing of small cell lung cancer using the MTT assay.

Campling, B. G., Pym, J., Baker, H. M., Cole, S. P., Lam, Y. M.

A simple colorimetric test, the MTT assay, has been adapted for chemosensitivity testing of human small cell lung cancer cell lines, and fresh tumour samples. Optimal conditions for clinical...

Multidrug resistance-associated antigens on drug-sensitive and -resistant human tumour cell lines.

Mirski, S. E., Cole, S. P.

In this paper the biochemical properties of the antigens detected by six murine monoclonal antibodies (MAbs) are described. These MAbs react selectively with the multidrug-resistant small cell lung...

Elevated expression of annexin II (lipocortin II, p36) in a multidrug resistant small cell lung cancer cell line.

The doxorubicin-selected multidrug resistant small cell lung cancer cell line, H69AR, is cross-resistant to the Vinca alkaloids and epipodophyllotoxins, but does not overexpress P-glycoprotein, a 170...
