Figure Lengend Snippet: RT-qPCR analysis of Etv4 and Etv5 levels in MZB cells from Cic f/f ;Cd19-Cre ( a ) and Atxn1l f/f ;Cd19-Cre ( b ) mice. N = 3 per group. c Flow cytometry of NOTCH1 and NOTCH2 levels in MZB cells infected with either a control (NC) or ETV4-expressing (ETV4) retrovirus. N = 6 per group. d ChIP-qPCR analysis of the Notch1 and Notch2 promoter regions containing ETV4 binding motifs. B-2 cells isolated from the spleens of Cic f/f ;Cd19-Cre mice were subjected to ChIP using either IgG or an anti-ETV4 antibody. N = 3 per group. Flow cytometry of splenic FOB and MZB cells ( e ), MZP cells ( f ), and T1B and T2B cells ( g ) in Cd19-Cre , Cic f/f ;Cd19-Cre , and Etv4 −/− ;Cic f/f ;Cd19-Cre mice. N = 7 for Cd19-Cre , N = 8 for Cic f/f ;Cd19-Cre , and N = 5 for Etv4 −/− ;Cic f/f ;Cd19-Cre . Ctrl: Cd19-Cre , cKO: Cic f/f ;Cd19-Cre , and DKO: Etv4 −/− ;Cic f/f ;Cd19-Cre . Flow cytometry of splenic FOB and MZB cells ( h ) and MZP cells ( i ) in Cd19-Cre , Atxn1l f/f ;Cd19-Cre , and Etv4 −/− ;Atxn1l f/f ;Cd19-Cre mice. N = 8 for Cd19-Cre , N = 6 for Atxn1l f/f ;Cd19-Cre , and N = 3 for Etv4 −/− ;Atxn1l f/f ;Cd19-Cre . Ctrl: Cd19-Cre , cKO: Atxn1l f/f ;Cd19-Cre , and DKO: Etv4 −/− ;Atxn1l f/f ;Cd19-Cre . j Surface expression levels of NOTCH1, NOTCH2, and CD21 in MZB and MZP cells from Cd19-Cre , Cic f/f ;Cd19-Cre , and Etv4 −/− ;Cic f/f ;Cd19-Cre mice. N = 5 per group. k Surface expression levels of NOTCH1, NOTCH2, and CD21 in MZB and MZP cells from Cd19-Cre , Atxn1l f/f ;Cd19-Cre , and Etv4 −/− ;Atxn1l f/f ;Cd19-Cre mice. N = 5 for Cd19-Cre and Atxn1l f/f ;Cd19-Cre , and N = 3 for Etv4 −/− ;Atxn1l f/f ;Cd19-Cre . The MFIs for NOTCH1, NOTCH2, and CD21 were determined using flow cytometry. Data represent 2–3 independent experiments. Statistics: two-tailed Student’s t -test ( a – d ) and one-way ANOVA with Tukey’s multiple comparisons test ( e – k ). Bar graphs present data as mean ± S.D. RT-qPCR quantitative real-time polymerase chain reaction, FOB follicular B cells, MZB marginal zone B cells, MZP marginal zone progenitor cells, and MFI mean fluorescence intensity. Source data are provided as a file.
