Article Title: Identifying Truly HPV-Driven Head and Neck Squamous Cell Carcinoma by QuantiGene-Molecular-Profiling-Histology Assay Allows for More Precise Prognosis Prediction

doi: 10.3390/ijms252413643

Figure Lengend Snippet: Selection of FFPE specimens from HNSCC patients for the biomarker expression study using QG-MPH. Out of 100 HNSCC cases, 97 were assigned. The specimens were tested by H&E staining for tumor tissue residues. A total of 25 cases were excluded due to non-sufficient tumor tissue. MPG and QG-MPH assays were performed with FFPE sections of 72 specimens, and 68 were valid for further analysis. Abbreviation: FFPE = formalin-fixed-paraffin-embedded; HNSCC = head and neck squamous cell carcinoma; H&E staining = hematoxylin and eosin staining; MPG = Multiplex Papillomavirus Genotyping assay; QG-MPH = QuantiGene-Molecular-Profiling-Histology assay; IHC = immunohistochemistry.

Article Snippet: RNA was released from FFPE sections (5 μm thickness, 5–10 pieces) using the QuantiGene FFPE Sample Processing Kit (ThermoFisher, Cat. #QS0109, Waltham, MA, USA) according to the manufacturer’s protocol.

Figure Lengend Snippet: ( A ) Chemical structures of C6 and C16. ( B ) Crystal structures of C6 or C16 bound to the WIN site of WDR5 with electrostatic surfaces mapped (PDB IDs: 6E23 ; 6UCS ). The image shows a close-up view of the WIN site. ( C ) Superimposed WIN site-binding conformations of C6 (green) and C16 (blue). ( D ) Transcript levels as determined by QuantiGene analysis of representative WDR5-bound (color) or non-bound (grayscale) ribosomal protein genes in MV4;11 cells treated with a serial dilution range of either C6 (left) or C16 (right) and relative to DMSO-treated cells (n = 2–3; mean ± SEM). Vertical dashed line indicates either 2 µM C6 (left) or 100 nM C16 (right). ( E ) Number of genes with significantly (false discovery rate [FDR] < 0.05) altered transcript levels following treatment of MV4;11 cells with C6 (2 µM) or C16 (100 nM) for 48 hr, as determined by RNA-Seq (n = 3). See for complete output of RNA-seq analysis. ( F ) Comparison of gene expression changes elicited by C6 (x-axis) and C16 (y-axis), represented as Log2 fold change (FC) compared to DMSO. WDR5-bound genes are colored red. Locations of RPL22L1 and ZMAT3 are indicated. ( G ) Overlap of genes with decreased (left) or increased (right) transcript levels in MV4;11 cells treated with C6 or C16. ( H ) Gene set enrichment analysis (GSEA) showing the distribution of genes suppressed in MV4;11 cells in response to C6 (left) or C16 (right) against the list of all genes bound by WDR5 in those cells . NES, normalized enrichment score. ( I ) Enrichment analysis of genes suppressed (left) or induced (right) by C6 or C16 in MV4;11 cells. KEGG and Hallmark.MSigDB pathways are shown. Fold enrichment of indicated pathways is presented on the x-axis, the number of genes is shown in italics in each bar, and colors represent -Log10 FDR. See for additional GSEA (Hallmark) and over-representation analysis (ORA) (Hallmark) analyses of differentially expressed genes. ( J ) Transcript level changes in WDR5-bound (left) and non-bound (right) RPGs elicited by C6 (top) or C16 (bottom). Figure 1—source data 1. Output of RNA-seq analysis of MV4;11 cells treated with C6/C16. Figure 1—source data 2. GSEA Hallmark and over-representation analysis (ORA) Hallmark enrichment analysis of differentially expressed genes in RNA-seq.

Figure Lengend Snippet: ( A ) Crystal structures of C6 or C16 bound to the WIN Site of WDR5 with electrostatic surfaces mapped (PDB IDs: 6E23 ; 6UCS ). ( B ) Viabilities of MV4;11 cells treated with a serial dilution range of either C6 (left) or C16 (right) for 72 hr, relative to viability of DMSO-treated cells (n = 3; mean ± SEM). ( C ) As in ( B ) but for MOLM13 cells.
