Small-cell carcinoma of the lung is a highly lethal form of cancer associated with a wide variety of paraneoplastic syndromes. Using the patch-clamp technique, we have directly demonstrated the presence of voltage-gated k4. Na4, and (a24 channels in three cell lines of human small-cell carcinoma, NCI-HI28, NCI-H69, and NCI-HI46. Whole-cell currents were measured from the tumor cells held at —...

Incubation of hen oviduct membranes with UDP-[14C]N-acetylglucosamine (GlcNAc) leads to the formation of four endogenously labeled lipids. One of these lipids has not previously been characterized. Based on its chromatographic behavior on SG-81 paper and DEAE-cellulose, it is a monophosphate diester. The oviduct lipid is extremely sensitive to mild acid hydrolysis and, based on a comparison wit...
