doi: 10.1101/2023.01.09.523344
Figure Lengend Snippet: (A) Chromosomal engineering strategies for the targeted deletion of chromosome arms: (1) ReDACT-NS: using CRISPR-Cas9 homology-directed repair, we integrated a positive-negative selection cassette encoding a fluorescent reporter, a positive selection marker, and a negative selection marker (HSV thymidine kinase) at a centromere-proximal region on chromosome 1q. We induced arm loss by generating a dsDNA break centromere-proximal to the cassette with Cas9, and isolated clonal populations of cells that were ganciclovir-resistant. (2) ReDACT-TR: We induced arm loss by generating a dsDNA break at a centromere-proximal location with Cas9 while providing cells with an ectopic telomere seed sequence for repair. (3) ReDACT-CO: We induced arm loss by generating a dsDNA break at a centromere-proximal location with Cas9, and isolated clonal populations of cells. For all three approaches, we screened clonal populations of cells for targeted chromosome loss through TaqMan CNV assays and validated their karyotypes through SMASH sequencing. (B) Representative SMASH karyotypes of the 1q-disomic clones generated from the 1q-trisomic cancer cell lines A2780, AGS, and A2058. Chromosome 1q is highlighted in blue. A complete list of aneuploidy-loss clones is included in . (C) 1q-disomic clones display decreased RNA expression and protein expression of genes encoded on chromosome 1q. RNA expression data was obtained through bulk RNA-seq and represents the average expression of genes by chromosome arm across multiple 1q-disomic clones for each cell line. Protein expression data was obtained through mass spectrometry, and representative data from one 1q-disomic clone is shown for each cell line. Data are log2 transformed, normalized to the parental cell line, and adjusted so that the mean expression across all chromosomes is 0. (D) 1q-disomic clones exhibit decreased anchorage-independent growth. The micrographs display representative images of colony formation for 1q-trisomic and 1q-disomic clones. (E) 1q-disomic clones exhibit impaired xenograft growth in vivo . 1q-trisomic and 1q-disomic cells were injected contralaterally and subcutaneously into immunocompromised mice. The graphs display the mean ± SEM for each trial. Representative mice are shown on the right. (F) SMASH karyotype of a 1q-disomic clone generated from the mammary epithelial cell line MCF10A. Chromosome 1q is highlighted in blue. (G) 1q-disomic MCF10A clones transduced with HRAS G12V exhibit decreased anchorage-independent growth relative to 1q-trisomic MCF10A cells. (H) 1q disomic MCF10A clones transduced with HRAS G12V clones exhibit impaired xenograft growth in vivo . 1q-trisomic and 1q-disomic cells were injected contralaterally and subcutaneously into immunocompromised mice. The graphs display the mean ± SEM for each trial. Representative mice are shown below. For anchorage-independent growth assays in D and G, the boxplots represent the 25th, 50th, and 75th percentiles of colonies per field, while the whiskers represent the 10th and 90th percentiles.

(B) A heatmap displaying the upregulation of 10 p53 target genes in A2780 1q-disomic clones. The TK+ clone indicates a clone that harbors the CRISPR-mediated integration of the HSV-TK transgene but that was not treated to induce chromosome 1q-loss. (C) Western blot analysis demonstrating activation of p53 signaling in 1q-disomic clones. GAPDH was analyzed as a loading control. The TK+ clone indicates a clone that harbors the CRISPR-mediated integration of the HSV-TK transgene but that was not treated to induce chromosome 1q-loss. (D) A waterfall plot highlighting the most-significant instances of mutual exclusivity between chromosome arm gains and mutations in cancer-associated genes. The complete dataset for mutual exclusivity and co-occurrence is included in . (E) Boxplots displaying the TP53-mutation phenocopy signature in cancers from the TCGA, split based on whether the cancers harbor a non-synonymous mutation in TP53. (F) A scatterplot comparing the association between chromosome arm gains and the TP53-mutation phenocopy signature in TP53-wildtype cancers from TCGA. Cancers with chromosome 1q gains are highlighted in blue. (G) Boxplots displaying the TP53-mutation phenocopy signature in cancers from the TCGA, split based on whether tumors harbor a gain of chromosome 1q. Only TP53-wildtype cancers are included in this analysis. (H) Boxplots displaying the expression of three p53 target genes – CDKN1A (p21), RRM2B, and GADD45A – in cancers from TCGA split based on the copy number of chromosome 1q. Only TP53-wildtype cancers are included in this analysis. (I) A CRISPRi competition assay demonstrates that gRNAs targeting MDM4 drop out over time in A2780 cells. In contrast, gRNAs targeting AAVS1 and PIP5K1A, another gene encoded on chromosome 1q, exhibit minimal depletion. (J) A schematic displaying the strategy for using paired CRISPR gRNAs to delete a single copy of MDM4 in a cell line with a trisomy of chromosome 1q. (K) SMASH karyotype demonstrating maintenance of the chromosome 1q trisomy in an MDM4 +/+/KO clone. Chromosome 1q is highlighted in blue. (L) 1q-disomic clones and MDM4 +/+/KO clones in A2780 exhibit comparable upregulation of p53 transcriptional targets, as determined through TaqMan gene expression assays. (M) MDM4 +/+/KO clones exhibit decreased anchorage-independent growth relative to the MDM4 +/+/+ parental cell line. (N) Induction of MDM4 cDNA in 1q-disomic clones in A2780 increases anchorage-independent growth.

Article Title: Oncogene-like addiction to aneuploidy in human cancers

Figure Lengend Snippet: (A) A schematic of the metabolism of two pyrimidine analogs, RX-3117 and 3-deazauridine. UCK2, a kinase encoded on chromosome 1q, phosphorylates these compounds to produce cytotoxic derivatives that can poison DNA and RNA synthesis. (B) Boxplots displaying the expression of UCK2 in cancer cell lines (left) and human cancers (right), divided based on the copy number of chromosome 1q. The boxplots represent the 25th, 50th, and 75th percentiles of the indicated data, while the whiskers represent the 10th and 90th percentiles of the indicated data. (C) Expression of UCK2 protein in cancer cell lines with 1q trisomies or following aneuploidy-elimination. (D) Cellular sensitivity of A2780 and MCF10A treated with different concentrations of RX-3117 or 3-deazauridine. (E) A schematic displaying cellular competition between trisomic and disomic cells. Under normal conditions, certain trisomies enhance cellular fitness, allowing these cells to overtake the population and enhance malignant growth (top). However, treatment with an “anti-trisomy” compound could selectively impair the growth of the aneuploid cells, keeping the population in a low-malignant state (bottom). (F) A cellular competition between fluorescently-labeled A2780 1q-trisomic and unlabeled 1q-disomic cells. These cells were mixed at a ratio of 10% to 90% and then cultured in either DMSO or RX-3117. While the trisomic cells quickly dominate the population in drug-free media, treatment with RX-3117 prevents the outgrowth of the 1q-trisomy subpopulation. *p < 0.05, ** p < 0.005, *** p < 0.0005
