LGR4 expression was not changed by TNFa or IL-1a treatment (Fig.S1). Overexpression of CA-Stat3 promoted cell proliferation in MG63 and U2OS cells (Fig.S2). The mRNA and protein levels of LGR4 were increased in osteosarcoma tissues from patients, which is well-correlated with the activation of Stat3 signaling, as evidenced by its phosphorylation (Fig.S3). The mRNA levels of Cyclin D1 and Cyclin E, two downstream target genes ofb-catenin, were also reduced in cells with Lgr4 deficiency (Fig.S4).
