Vero E6suggested: RRID:CVCL_XD71)HepG2 cells were cultured in Iscove’s Modified Dulbecco’s Medium (IMDM) supplemented with 10 % fetal calf serum (FCS) at 37 °C and 5 % CO2. 2.2 Reagents: Silvestrol was obtained from the Sarawak Biodiversity Centre (Kuching; North-Borneo, Malaysia; purity > 99%). HepG2suggested: NoneExperimental Models: Organisms/Strains Sentences Resources CR-31-B (-) and CR-31-B (+) (Wolfe et al., 2014) were dissolved in DMSO at a concentration of 10 mM and stored at −20 °C. 2.3 Dual luciferase reporter assay: The dual luciferase assay was performed as described previously in at least three independent replicates (Müller et al., 2018a, Müller et al., 2020). CR-31-B (-suggested: NoneSoftware and Algorithms Sentences Resources EC50 values were then calculated by non-linear regression analysis using GraphPad Prism 6.0 (GraphPad Software).
