    A. Ctrl-KO and SNX9-KO MCF10A cells were treated with <t>etoposide</t> at 25 and 50 μM (indicated by triangles) and analyzed by IB for total and phosphorylated (p53 ser15 ) p53, and the p53 target genes MDM2 and CDKN1A. Vinculin (VCL), loading control. B . RT-qPCR analysis of MDM2 and CDKN1A expression in the samples described in “A”. Data are from three independent experiments and expressed as mean ± SD. *, p<0.05; **, p<0.01. C. 3D reconstruction of MCF10A-p53-KO recipient cells treated for 8 h with EVs purified from the conditioned medium of HEK-293 cells transfected with p53-HA. Recipient cells were treated with etoposide (50 μM for 8 h) and analyzed by IF using an anti-p53 antibody (green) and DAPI (blue). Bar, 20 μm. D. MCF10A-p53-KO recipient cells were treated for 8 h with etoposide (50 μM) and EVs purified from HEK-293 WT (EV) or HEK-293 p53-HA (EV p53-HA) cells as indicated. After treatment cells were harvested and analyzed by RT-qPCR for CDKN1A levels. Data are from three independent experiments and expressed as mean ± SD. * p<0.05, ** p<0.01 and *** p<0.001 vs . same condition in cells not treated with EVs (only the most relevant statistical comparisons are shown). E. Scheme of the co-culture experiment shown in in panel F. a) MCF10A-p53-KO-H2B-Cherry cells were plated onto coverslips. b) After 24 h, coverslips were harvested and seeded (c) in plates in which the indicated cell lines had been previously seeded. Cells were then treated with etoposide (50 μM) or mock-treatment for 8 h. d) Coverslips were harvested and analyzed for purity of H2B-Cherry labeled cells (Fig. S10D) and for the levels of CDKN1A mRNA (panel F). Details are in Materials and Methods. F . RT-qPCR analysis of CDKN1A levels in harvested H2B-Cherry labeled MCF10A-p53-KO cells, co-cultured as described in panel “ E ”. Data are from three independent experiments and expressed as mean ± SD. **, p<0.01; n.s., not significant (only the most relevant statistical comparisons are shown). G . SAOS2 cells were treated with EVs purified from the indicated MCF10A cell lines (see experimental scheme in Fig. S10F), and cell viability/growth was assessed indirectly by quantifying intracellular ATP levels using a luminescence-based assay. Data are from ten samples/condition from two independent experiments and expressed as mean ± SD. One-way ANOVA test: *, and ***, p < 0.05 and < 0.001, respectively, vs . SAOS2 treated with EVs derived from MCF10A-p53-KO cells.
