miRNA-221-3p derived from M2-polarized tumor-associated macrophage exosomes aggravates the growth and metastasis of osteosarcoma through SOCS3/JAK2/STAT3 axis


Figure 7. Inhibiting JAK2/STAT3 reversed the oncogenic property of miR-221-3p. LY2784544 (3 nM) was applied to treat Saos2 cells, which were transfected with miR-221-3p mimics. (A) CCK-8 tested cell viability. (B) Cell proliferation was monitored by the colony formation assay. (C) FCM was utilized to detect cell apoptosis. (D) The profiles of Bax, Bcl2 and Cleaved Caspase-3 were assessed by WB. (E) WB was conducted to detect the SOCS3/JAK2/STAT3 profile and its phosphorylation.
