HMGB1 inhibitor (Glycyrrhizin) notably suppresses in vitro and in vivo tumor growth of KMD4Dlow ESCC. (A-C) Detection of the half maximal inhibitory concentration (IC50) values of Glycyrrhizin in three ESCC cell lines (KYSE30, EC109 and KYSE150). (D-F) The cell growth ability of the ESCC cells (KYSE30, EC109 and KYSE150) were all remarkably impaired with Glycyrrhizin treatment in a dose‐dependent manner. (G) HMGB1 inhibition (Glycyrrhizin) effectively suppressed ESCC subcutaneous tumour growth in nude mice (n = 5). (H) The tumour volume was detected every other day, and tumour growth curves were generated. (I) The tumours were extracted and weighed after 35 days. *P < 0.05, **P < 0.01, ***P < 0.001.
