Figure Lengend Snippet: a WB analysis of ZBTB11 in H1299-EV or H1299-MMP9-Flag stable cells upon endogenous ZBTB11 depletion. Cell migration ( b , c ) or invasion ( d , e ) of H1299-EV or H1299-MMP9-Flag stable cells upon ZBTB11 depletion (mean ± S.E.M., n = 3 biologically independent samples, two-sided t -test). f WB analysis of SET in H1299-EV or H1299-MMP9-Flag stable cells upon endogenous SET depletion. Cell migration ( g , h ) or invasion ( i , j ) of H1299-EV or H1299-MMP9-Flag stable cells upon SET depletion (mean ± S.E.M., n = 3 biologically independent samples, two-sided t -test). k ChIP–qPCR analysis of the enrichment of ZBTB11 and SET at MMP9 loci in H1299 cells (mean ± S.E.M., n = 3 experimental replicates, two-sided t -test). l Re-ChIP–qPCR analysis of SET binding to MMP9 loci following primary ChIP with anti-ZBTB11 antibody in H1299 cells (mean ± S.E.M., n = 3 experimental replicates, two-sided t -test). m ChIP–qPCR analysis of SET enrichment at MMP9 loci in H1299-ZBTB11-iKO cells upon doxycycline (Doxy) treatment (mean ± S.E.M., n = 3 experimental replicates, two-sided t -test). n ChIP–qPCR analysis of ZBTB11 enrichment at MMP9 loci in H1299-EV or H1299-FH-SET stable cells (mean ± S.E.M., n = 3 experimental replicates, two-sided t -test). o Luciferase assays of SET/ZBTB11-driven transcriptional of MMP9 . The EV or FH-ZBTB11 construct was transfected into H1299-EV or H1299-FH-SET stable cells, together with luciferase reporter and Renilla control vector, for 24 h (mean ± S.E.M., n = 3 experimental replicates, two-sided t -test). p Schematic diagram (created with BioRender) of the workflow for analyzing tumor metastasis in vivo. q WB analysis of ZBTB11 and MMP9 in H1299-Luc2-tdT-2 cells stably transfected with the ZBTB11-expressing construct (ZBTB11-OE) and/or shRNA targeting MMP9 (MMP9-KD). r Bioluminescent image of lung metastasis from the primary tumors in a mouse model where H1299-Luc2-tdT-2 cells with ZBTB11-OE/MMP9-KD were subcutaneously inoculated into the flanks of immunodeficient B-NDG (NSG) mice. s Quantitative analysis of the metastasis of cancer cells in the lung based on ( r ) (mean ± S.E.M., n = 4 mice per group, two-sided t -test). c , h shared the same si-Ctr group for quantitative analysis; ( e ) and ( j ) shared the same si-Ctr group for quantitative analysis.
