Extended Data Fig. 9. A co-amplified enhancer on the D458 ecDNA promotes MYC expression.

Extended Data Fig. 9

Relative expression of MYC (a-b), and OTX2 (c-d), measured by qPCR (2−ΔΔCt), in D458 and D283 cell lines upon CRISPRi targeting of an accessible locus within a known MYC superenhancer which promotes D458 proliferation (see also Fig. 4h). sgNT: nontargeting control; sgMYC-SE-A-C: sgRNAs targeting the MYC enhancer at D458_peak_30782, positions chr8:127330655, chr8:127330840, and chr8:127330927 (hg38) respectively. qPCR was performed on all guides in triplicate; each technical replicate is shown. Bars represent median +/− 95% CI. ** adjusted p = 0.002; *** adjusted p = 0.0008; one-sided nested ANOVA with Dunnett’s correction.
