Figure Legend Snippet: CD73/adenosine pathway was upregulated in EGFR-mutant tumors. (A-D) NT5E (CD73), CD38, ADORA1 and ADORA2A RNA expression levels were compared between EGFR-mutant and WT tumors in PROSPECT, ICON and TCGA. Fold-change was calculated comparing expression of EGFR-mutant tumors to WT, using the lower expressed as the denominator. A positive fold-change value indicates overexpression in EGFR-mutant tumors and a negative value indicates decreased expression in EGFR-mutant tumors. The univariant analysis was used for p-value. (E) Feature plots showing EPCAM+ cells from the 3 single-cell RNAseq samples (right panel: cells by sample; middle panel: cells by malignant versus normal; left panel, the expression levels of NT5E in each cell) (F). Porportion of NT5E expression cells in each sample. (G) phosphorylated EGFR, CD73 and CD38 protein levels were compared between EGFR-mutant and WT tumors in the ICON cohort, from the reverse-phase protein array (RPPA).
Techniques Used: Mutagenesis, RNA Expression, Expressing, Over Expression, Protein Array
Figure Legend Snippet: CD73 blockade modulates T cell composition and function in EGFR-mutant non-small cell lung cancer cells. (A) CD73 cell surface expression on H1975 cells was assessed by flow cytometry with or without control and CD73 siRNAs. (B) Healthy donor PBMCs were incubated with conditioned median collected from H1975 cells after siRNA treatment. T regulatory cell population was assessed in each condition by flow cytometry using CD4+ and FoxP3+ as markers. (C) Healthy donor PBMCs were incubated with conditioned median collected from H1975 cells or H1975 after recombinant CD73 overexpression. T regulatory cell population was assessed by flow cytometry using CD4+ and FoxP3+ as markers. (D) Healthy donor PBMCs were co-cultured with H1975 cells with anti-CD73 and anti-PD-1 treatment, alone or in combination. Percent of tumor cell lysis was assessed using cytotoxicity assay. (E) Healthy donor PBMCs were co-cultured with H1975 cells with anti-CD73 and anti-PD-1 treatment, alone or in combination. The cell medium was collected and assessed for interferon release by ELISA INF-gamma assay. Student t-test was used, statistical significance: * indicates p value less than 0.05, ** indicates p value less than 0.005, *** indicates p value less than 0.0005, and **** indicates p value less than 0.0001.
Techniques Used: Mutagenesis, Expressing, Flow Cytometry, Incubation, Recombinant, Over Expression, Cell Culture, Lysis, Cytotoxicity Assay, Enzyme-linked Immunosorbent Assay
Figure Legend Snippet: Anti-CD73 therapy-induced tumor reduction in EGFR-mutant murine lung cancers. (A) NT5E (CD73) and ADORA1 RNA expression levels in EGFR-mutant tumors and normal lung. (B) adenosine and AMP metabolite levels in EGFR-mutant tumors and normal lung. (C) CD73 immunohistochemistry for EGFR-mutant tumors and adjacent normal lung. (D) The change of tumor sizes with 2 weeks of treatment was documented and compared between vehicle-treated and anti-CD73 treated groups.
Techniques Used: Mutagenesis, RNA Expression, Immunohistochemistry
