Fig. 2 SPOP mediates DNA damage repair.
(A) Evaluation of SPOP function during zebrafish development. Phenotype of morpholino-mediated Spop knockdown (MO5) in zebrafish embryos at 70 hr post fertilization (hpf). Injection of human SPOP mRNA (250 pg) rescued the phenotype. (B) Quantification of the rescue of SPOP phenotype after ectopic expression of human SPOP mRNA. Results are represented as s.e.m. (C) Whole mount TUNEL assay to determine apoptosis in zebrafish embryos. Arrows point to apoptotic cells (brown). Shown are representative images. (D) Heatmap representation of gene expression differences in zebrafish embryos ectopically expressing SPOP-wt or SPOP-F133V compared to SPOP knockdown by morpholino (MO). The list of genes can be found in Figure 2—figure supplement 3. Number of genes per block: A (198), B (429), C (223). (E) Gene set enrichment analysis (GSEA) of RNA sequencing data derived from zebrafish embryos expressing SPOP-wt or SPOP-F133V (24 hpf). Enrichment plot for the BRCA1 gene signature is shown. Molecular Signatures Database (MSigDB) systematic name indicated in brackets. (NES) Normalized Enrichment Score. (FDR) False Discovery Rate. (F) Dendrogram of human primary prostate cancer cases based on BRCA1 knockdown genes (MSigDB: M2748). Unsupervised clustering of RNA-seq data from human primary prostate cancer with wild-type (n = 53) or mutant SPOP (n = 11), performed on the BRCA1 knockdown gene signature (M2748) identified in zebrafish embryos by GSEA as shown in (E).
