We have found weaker expression of phosphorylated NF-κB in BCL1 cells in vitro treated with Pt(S-pr-thiosal)2 complex compared to untreated cells (Figure 7a), while in the tumor tissue of mice treated with this complex, a significantly lower percentage of tumor cells which express the active form of NF-κB was observed (Figure 7b,c). This evidence concerns the gene CCND1 and neoplasm.
