Fig. 7From: Recombinant Expression and Bioactivity Comparison of Four Typical Fungal Immunomodulatory Proteins from Three Main Ganoderma SpeciesCytotoxic effects of four Ganoderma FIPs towards A549 (a), Hela (b) and MCF-7 (c) cancer cell lines. All cells were treated with rFIP-gap1, rFIP-gap2, rLZ-8 and rFIP-gsi at concentration ranging from 2 and 32 μg mL− 1. The inhibitory rates were calculated according to cell viabilities measured by MTT assays and the half-maximal inhibitory concentration (IC50) was deduced from the graphsBack to article page
