Abstract

MCF7 breast cancer cell line, carrying a luciferase reporter gene under the control of nuclear factor kappa B (NF-κB)-responsive promoter, was established and used for the screening of fungal organic extracts for their ability to interfere with the NF-κB activation pathway. Twenty-eight crude fungal extracts, out of 242, were found to inhibit NF-κB reporter activity by more than 40%. Furthermore, positive extracts were used to evaluate their antiproliferative activity as well as their ability to influence the phosphorylation and degradation levels of IκBa. Fungal extracts prepared from Marasmius oreades and Cyathus striatus showed significant inhibitory effects on the NF-κB activation pathway. Taken together, our results support the notion of the presence of novel activities that might be utilized as cancer therapeutics.
