CAPE reduces Sox10 activity. (A) ATAC-seq was conducted on sox10:Kaede+ cells from DMSO- or CAPE-treated embryos at two stages. CAPE reduces chromatin accessibility at the mitfa promoter in sox10:Kaede+ cells, and Sox10 binds the mitfa promoter in a zebrafish tumor cell line. (B) Crestin binds Sox10 but does not show a change in chromatin accessibility with CAPE treatment. Bar indicates region of crestin sequence similarity (chr4:41,270,000). (C) HOMER analysis of 20 ss ATAC-seq peaks revealed an enrichment for Sox and MITF motifs when comparing unique peaks in DMSO-treated embryos (% target) to all peaks in CAPE-treated embryos (% background). (D) CAPE (5 μM) prevents sox10 RNA (30 pg) from increasing crestin:EGFP expression. (E) Quantification of experiment shown in (D). Sum of three clutches from two independent experiments is shown. Figure 3—figure supplement 1 shows that tfap2c RNA increases crestin:EGFP expression in both DMSO- and CAPE-treated embryos, and that the number of sox10:Kaede+ cells does not change with CAPE treatment. |
