(F) Co-IP assay using antibody specific for Flag showed that Flag-Rubicon-S interacted with UVRAG and Beclin1(Right), while Flag-Rubicon-L could not bind to UVRAG and Beclin1 in T24 cells (Left). The precipitate was subjected to western blotting with the antibodies against Flag, UVRAG, and Beclin1. (G) The expression levels of LC3B and P62 in CUL5-KO T24 cells were detected by western blotting. (H) CUL5-WT, CUL5-KO#1, and CUL5-KO#2 T24 cells were transfected with the mCherry-EGFP-LC3B. The autophagosomes with yellow puncta and autolysosomes with red puncta. Bar: 10 μm. (I) Western blotting with the indicated antibodies in CUL5-WT and CUL5-KO T24 cells transfected with scramble or sh-PTBP1#1. (J) Western blotting with the indicated antibodies in CUL5-WT and CUL5-KO T24 cells transfected with scramble or sh-RUBCN-L, and agarose gel electrophoresis for analysis of RUBCN isoforms. (K) CUL5-WT, CUL5-KO#1, and CUL5-KO#2 T24 cells were transfected with the scramble or sh-RUBCN-L, and then co-cultured with CD8 + T cells, and cell viability was measured by CCK-8. (L) Western blotting with the indicated antibodies in CUL5-WT and CUL5-KO T24 cells transfected with scramble or sh-RUBCN-S, and agarose gel electrophoresis for analysis of RUBCN isoforms. (M) CUL5-WT, CUL5-KO#1, and CUL5-KO#2 T24 cells were transfected with the scramble or sh-RUBCN-S, and then co-cultured with CD8 + T cells, and cell viability was measured by CCK-8. (N) The expression levels of MHC-I (HLA-A, -B, -C) in CUL5-KO T24 cells co-cultured with CD8 + T cells were detected by western blotting. Data are presented as the means ± SD from three independent experiments. Student t test was applied to analyze and compare the data in C, D, K, and M. ns, nonsignificant; ** P < 0.01; *** P < 0.001.
