In an effort to investigate the role of creatine kinase and its substrates in malignancy we have tested the effect of cyclocreatine [1-carboxymethyl-2-iminoimidazolidine (CCr)] on the growth of tumor cells in vitro and in vivo. CCr is phosphorylated by creatine kinase to yield a synthetic phosphagen [(N-phosphorylcyclocreatine (CCr approximately P)] with(More)
Oligodeoxyribonucleotides targeted against respiratory syncytial virus (RSV) genomic RNA inhibited RSV replication in cell culture by an apparent antisense mechanism. HEp-2 cells were infected with RSV strain A2 and incubated in the presence of oligonucleotides. Virus replication was measured by enzyme-linked immunosorbent assay (ELISA), virus yield assay,(More)
Epithelial voltage-gated potassium (K) channels have been well studied using electrophysiological methods, but little is known about their structures. We tested the hypothesis that some of these channels belong to the Shaker gene family, which encodes voltage-gated K channels in excitable tissues. From published sequences of Shaker proteins in Drosophila,(More)
