The fungus induced the expression of the tumor suppressor p53 and the cyclin-dependent kinase inhibitor p21 (CIP1/WAF1), but inhibited the phosphorylation of retinoblastoma protein (Rb) in MCF-7 and HT-29 cells, in breast and colon cancer cells, respectively [107]. This evidence concerns the gene TP53 and malignant colon neoplasm.
