Rotenoids mediate potent cancer chemopreventive activity through transcriptional regulation of ornithine decarboxylasetissue plasminogen activator-mediated thrombolysis
(1995)For the discovery of new cancer chemopreventive agents, we have studied the potential of plant extracts to inhibit phorbol ester-induced ornithine decarboxylase (ODC) activity in cell culture. Four active rotenoids were ...

Selection of cancer chemopreventive agents based on inhibition of topoisomerase II activity
(2000)The present study was undertaken to determine if in vitro inhibition of one or both of the two most dominant mammalian DNA topoisomerases (topos) is common among chemopreventive agents. To determine if an agent was a topo ...

Separation of the complexes formed between the regulatory and catalytic subunits of cyclic adenosine monophosphate-dependent protein kinase and topoisomerase I activity in preovulatory follicle-enriched immature rat ovaries
(1989)Our previous studies have shown that the regulatory subunits of the type II form of cAMP-dependent protein kinase (R‖) present in soluble extracts of immature rat ovaries elute from diethylaminoethyl-cellulose as three ...

Structure-activity relationships of brassinin in preventing the development of carcinogen-induced mammary lesions in organ culture
(1994)Brassinin, a pkytoalexin, is found in Chinese cabbage. Previously, we showed that brassinin significantly inhibited dimethylbenz(a)anthracene (DMBA)-induced mammary lesions in organ culture. Moreover, it was an effective ...
