(A). RT-qPCR showing the expression of PRL in RS4;11 cell line and LOC79217 in REH and RS4;11 cells. Statistical comparisons were completed using a two-tailed T-test; p < 0.05 (*); p < 0.01 (**); p ≤ 0.0005 (***). (B) Correlation between SOX4 and CASC15 expression in ETV6-RUNX1-translocated primary B-ALL samples (left panel), B-ALL cell lines (middle panel) and AML samples (right panel). (C) Correlation between SOX4 and CASC15 expression in publically available datasets (Cancer cell line encyclopedia) [29] in AML cell lines (top left), B-ALL cell lines (top right), DLBCL (bottom left) and other non-hematopoietic cell lines (bottom right). High degrees of correlation are seen in AML and B-ALL cell lines. (D) MTS assay showing no significant difference cell proliferation upon CASC15 knockdown by siRNA 1-2in RS4;11 cell line. (E) Strategy to knockout CASC15 using CRISPR/Cas9-mediated gene editing. Target sites that were utilized are denoted, superimposed on the exon-intron structure of CASC15. (F)RT-qPCR to measure CASC15 expression following CRISPR/Cas9-mediated gene editing of CASC15 in RS4;11 cells. (G-J)T7 Endonuclease assay showing the presence of heteroduplex DNA generated by CRISPR-Cas9-mediated cleavage at the transcription start at exon 1 (C1) (G), splice junction at exon 9 (C9) (H), exon 11 (C11) (I) and poly A signal site (C12) (J). T7 enzyme cleavage is detected by the presence of multiple bands in the C1, C9, C11 and C12 integrated cells compared to the vector. (PDF 742 kb

(A) CASC15 expression is higher in RUNX1 translocated patients respect to other B-ALL subtypes with aberrancies related to chromosome 21. Probe 229280_s_at, HGU133 plus 2 Affymetrix (DS-ALL, Down Syndrome) (1- way ANOVA, p < 0.01). (B) CASC15 expression is higher in RUNX1 translocated patients respect to other AML subtypes. Probe TC06000136.hg.1 HTA 2.0 Affymetrix. (1- way ANOVA, p < 0.01). Comparisons were made using a two-tailed T-test, statistically significant differences are denoted as follows: ** P < 0.01. Source of data for (A) and (B): two datasets deposited in NCBI’s Gene Expression Omnibus database (GEO) (N = 102 ALL, N = 85 AML; GSE17459 and GSE75461) [25, 26]. (C) Diagram showing 5′ and 3′ RACE product aligned with Ref sequence obtained from the UCSC genome browser. 5′ RACE primers are shown in blue. Unannotated exons are shown in yellow. (D-E) Gel showing 5 and 3′ RACE products. (F) Kaplan Meier survival analysis for two patient groups (high and low CASC15 expressers) shows that low CASC15 expression shows a trend towards worse overall survival (Log Rank Test, P-value, n.s. p = 0.18). The two groups were dichotomized based on two step cluster analysis using SPSS software. (G) Schematic showing the exon-intron structure of the two isoforms of CASC15 (H) Schematic showing the exon-intron structure of the mouse Casc15. (I-K) RT-qPCR data showing expression of CASC15 in cytoplasm and nuclear fractionations of from REH (I), RS4;11 (J) and 697 cell lines (K). Abbreviations: WCL (whole cell lysate), C (cytoplasmic fraction), and N (nuclear fraction). GAPDH and CELF4 were used as positive controls for cytoplasmic and nuclear-localized mRNAs, respectively [5]. 1 and 2 are biological replicates. (PDF 671 kb
