Fig. 8. In osteosarcoma, TRIM21 induced the degradation of SGLT2 and the overexpression of SGLT2 at the protein level.

Fig. 8

The SGLT2 inhibitor significantly upregulated the STING expression and activated the STING/IRF3/IFN-β pathway. Therefore, the combined treatment with SGLT2 inhibitor and STING agonist 2’3’-cGAMP exerted synergistic antitumor effects in osteosarcoma, as SGLT2 inhibitor 2’3’-cGAMP activate the STING/IRF3/IFN-β pathway via different mechanisms.
