LC-MS/MS analysis of the interaction between SGLT2 and TRIM21 (a) based on the detection of the peptide of TRIM21 (b). c Analysis of the interaction between SGLT2 and TRIM21 by co-immunoprecipitation. Western blot analysis of the protein expression levels of SGLT2 in TRIM21-overexpressed (d) and -silenced (e) MG-63 and MNNG/HOS cells. GAPDH served as an internal reference. f Western blot analysis in MG-63 cells transfected with sh-TRIM21 or TRIM21 plasmid for 48 h. Cells were treated with MG132 for 8 h before harvesting. g Western blot analysis of the protein expression levels of SGLT2 in TRIM21-overexpressed MG-63 and MNNG/HOS cells for 48 h. Cells were treated with MG132 for 8 h before harvesting. GAPDH served as an internal reference.
