Figure Legend Snippet: Longitudinal single-cell RNA and ATAC atlas of pediatric high-grade glioma (pHGG) (A) Overview of the multiomics studies on patient-matched longitudinal pHGG specimens. (B and C) Uniform manifold approximation and projection (UMAP) of (B) snRNA-seq data (401,253 cells) and (C) snATAC-seq data (118,736 cells) annotated by major cell type category (left) and stacked bar plot of cell-type proportions across dataset comparing initially resected pHGG samples with post-therapy samples. (D) Cell-type proportions in snRNA-seq data across each patient and therapeutic time point, along with a summary of patient demographics and molecular subtype. (E and F) Shifts in cell-type proportions for each patient between initial resection and post-therapy time points in (E) snRNA-seq ( n = 14 initial/post-therapy paired samples) and (F) snATAC-seq ( n = 11 paired samples). Post-therapy samples were merged for one patient with three longitudinal samples. A two-sided Wilcoxon signed-rank test for paired samples was used.
Techniques Used: Single Cell
Figure Legend Snippet: Transcriptional regulation of pHGG neoplastic cell states (A) Stacked bar plot of cell-type proportions of neoplastic cell states across dataset comparing initial resection and post-therapy samples. AC, astrocyte; GPC, glial progenitor cell; MES, mesenchymal; OC, oligodendrocyte; OPC, oligodendrocyte progenitor cell; NPC, neural progenitor cell; NEU, neural. (B) Representative ATAC signal tracks of FGFR1 locus and gene expression across cell states and time points. The link track represents the predicted enhancer-promoter interactions colored by the regression coefficient, and the TF motifs present at the enhancer peaks are indicated. Differentially accessible peaks between time points are highlighted. ∗∗∗ p < 0.0001, significance in gene expression or accessibility in FGFR1 ; ns, not significant, using one-sided Wilcoxon rank-sum test. (C) Shifts in neoplastic cell state proportions for each patient between initial resection and post-therapy time points in snATAC-seq ( n = 11 paired samples). Post-therapy samples were merged for one patient with three longitudinal samples. A two-sided Wilcoxon signed-rank test for paired samples was used. (D) Heatmap of differential transcription factor (TF) motif accessibility in each pHGG neoplastic cell state. Values are Z score-normalized deviation scores calculated using chromVAR. The differential TF accessibility analysis was performed by a Wilcoxon rank-sum test, comparing chromVAR deviation score between each cell state and the other cell states. The top 20 differential TFs are displayed for each state. (E) Overview of top 15 significant transcriptional regulators for each neoplastic cell state based on predicted enhancer-promoter interactions and TF-target gene pairs. The size of the dot indicates the fraction of the total gene targets in the network regulated by each TF. Color indicates chromVAR deviation Z score as in (D). (F–G) Transcriptional regulatory networks (TRNs) for (F) MES-like state and (G) OPC/NPC-like state, showing top 50 upregulated genes and top 15 TFs in each TRN. TRNs represent all cells within the respective clusters across patients and time points. Diamond nodes represent TFs, and circle nodes represent target genes. Node size is proportional to the average gene expression for target genes and average chromVAR Z score for TFs. Node color is proportional to the average log 2 fold change of the gene in that cell state post-therapy across all cells. Edge line thickness is proportional to the linear regression coefficient for the predicted enhancer-promoter interaction and the fraction of cells with chromatin accessibility at the enhancer peak.
Techniques Used: Gene Expression
Figure Legend Snippet: Identifying therapeutic sensitivities through in vitro drug screening (A) A linear mixed model was used to identify differentially expressed genes within neoplastic cells overall between initial resection and post-therapy time points accounting for individual patient variability. Volcano plot shows the log fold change and adjusted p value for each gene included in the model, with selected genes labeled. Log fold change >0.5 and adjusted p value < 0.05 are indicated with dashed lines. (B) Gene set enrichment analysis (GSEA) of Hallmark (H) and KEGG (K) pathways across all genes in (A) ranked by log fold change. (C) Schematic of radiation experiment. Cells were treated with 4 Gy of ionizing radiation and allowed to recover for 4 weeks before undergoing bulk RNA sequencing. (D) GSEA of post-radiation changes using analogous GLMM as in (B) using three pHGG cell lines. Significant pathways shared with (B) are shown and highlighted in red in both panels. (E) Top gene targets by aggregate ranking score. Criteria include screening against drug databases, LINCS1000 compound perturbations, DepMap, differential gene expression, and participation in ligand-receptor signaling as a receptor target. (F) Selected growth curves from in vitro drug screening in human pHGG cell lines grown in spheroid culture. Cells were treated with drugs at indicated concentrations, and growth was monitored using a fluorescent reporter over 72 h of drug treatment ( n = 24 control, 2 drug-treated replicates each). y axis indicates the log2 fold change of total fluorescence signal from the zero time point. Positive values indicate a net proliferation, while negative values indicate net cell death. IC 50 values (in nM) are indicated for each drug and cell line. Data are shown as mean ± SEM with n = 2 replicates per condition. (G) Synergy scores (zero interaction potency) for combinations of trametinib and navitoclax across concentrations. Median ZIP scores are 18.1 (913 cell line), 10.5 (195 cell line), −1.49 (1763 cell line), and 0.82 (3058 cell line).
