Harmful algal blooms (HABs) cause significant economic and ecological damage worldwide. Despite considerable efforts, a comprehensive understanding of the factors that promote these blooms has been lacking, because the biochemical pathways that facilitate their dominance relative to other phytoplankton within specific environments have not been identified.(More)
The food antioxidants butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) were tested as tumor promoters on CD1 female mice initiated with 7, 12-dimethylbenz(a)anthracene (DMBA). At a dose of 1 mg twice weekly they did not promote skin tumors. Nor did they produce tumors when tested as a complete carcinogen without DMBA initiation. The(More)
To better define thrombin-receptor interactions, we synthesized human thrombin peptides and identified binding-domain peptides that bind thrombin receptors and activate mitogenic signals (Glenn, K.C., G.H. Frost, J.S. Bergmann, and D.H. Carney. 1988. Pept. Res. 1:65-73). Treatment of full dermal dorsal incisions with a single topical application of thrombin(More)
In the semisynthetic compound phorbol 12-retinoate 13-acetate (PRA), the antipromoting principle of vitamin A acid is combined with the structure of a phorbol ester tumor promoter. In skin of NMRI mice, a single topical application of PRA induces skin inflammation, epidermal proliferation, and sustained hyperplasia to a similar extent and apparently along(More)
The potent epoxide hydrase inhibitor, 1,1,1-trichloro-2,3-propene oxide (TCPO), enhanced the tumor-initiating ability of benzo[alpha]pyrene (BP) and 3-methylcholanthrene (MCA) but had no effect on 9,10-dimethyl-1,2-anthracene (DMBA) initiation in a two-stage system of tumorigenesis in female Charles River CD-1 mice. The tumor-initiating ability of(More)
