STAT3

Dihydroisotanshinone I can inhibit the migration of both androgen-dependent and androgen-independent prostate cancer cells. Dihydroisotanshinone diminishes the ability of prostate cancer cells to recruit macrophages and reduces the secretion of chemokine (C-C motif) ligand 2 (CCL2) from both macrophages and prostate cancer cells in a dose-dependent manner. It inhibits the protein expression of p-STAT3 and decreases the translocation of STAT3 into nuclear chromatin. It also suppresses the expression of tumor epithelial-mesenchymal transition genes, including RhoA and SNAI1[1]. Pretreating the cells with dihydroisotanshinone I at concentrations ranging from 2.5 μM to 20 μM for 24 hours cause dose-dependent protection against hepatotoxicity induced by menadione. Adding dihydroisotanshinone I to freshly isolated hepatocytes at concentrations between 50 nM to 200 nM inhibit NADH-induced superoxide production dose-dependently[2].

Dihydroisotanshinone I is dissolved in ethyl acetate and mixed with the culture medium. The final concentration of ethyl acetate is 0.1% (v/v). Cell are treated with 2.5, 5, 10, and 20 μM dihydroisotanshinone I for 24 hours. The cell viability is measured using the MTT assay[2].
