Figure Legend Snippet: ( A-D ) Luc–encoding RNA formulated as RNA-LPX was administered i.v. to non-tumor bearing (A, B; n=3) or CT26 metastases-bearing (C, D) BALB/c mice (n=3-9). ( A ) BLI of total body, ( B ) normalized organ signal from explanted organs. Data were analyzed by ordinary one-way ANOVA and Tukey’s test for multiple comparisons. ( C ) Kinetics of BLI of the lung signal in metastases-bearing mice, significance was determined by mixed-effects analysis with Geisser-Greenhouse correction and Tukey’s test for multiple comparisons. ( D ) Luc RNA, luc protein and CD31 (PECAM-1) were detected via RNAscope and immunohistochemistry on consecutive sections 1, 6 or 24 hours post injection, scale bar: 100 µm, tumor tissue is indicated with dashed line. ( E ) Cytokine quantification in lung after the indicated time points. ( F ) Cytokine fold increase in lung normalized to spleen at 6 hours after injection. ( G ) FDG positron emission tomography (PET) imaging 24 h after cytokine RNA mix injection into naïve mice, ( H ) ex vivo measurement of FDG uptake. Significance was determined using a two-tailed t-test for unpaired samples.
Techniques Used: RNAscope, Immunohistochemistry, Injection, Positron Emission Tomography, Imaging, Ex Vivo, Two Tailed Test
Figure Legend Snippet: ( A ) Experimental design: BALB/c mice (n=15 per group) were injected i.v. with CT26 tumor cells; subsequently, cytokine RNA mix or irrelevant RNA was administered i.v. as RNA-LPX twice per week for a total of 8 injections from d3 to d27. Survivor mice from the cytokine RNA mix-treated group (n=5) compared to naïve BALB/c mice (n=10) were re-challenged with CT26 tumor cells. ( B ) Survival after the initial i.v. CT26 tumor cell inoculation. ( C ) Survival after re-challenge. Significance was determined via Mantel-Cox logrank. ( D-F ) BALB/c mice (n=5 per group) were injected i.v. with CT26 tumor cells, RNA-LPX was administered i.v. at d3, d6 and d10 p.t.i., mice were sacrificed at d11, lungs were collected and analyzed via flow cytometry. Significance for pairwise comparisons was determined by unpaired two-tailed t-test. Flow cytometric analysis of ( D ) tumor burden, ( E ) CD8 + T and NK cells and ( F ) CD4 + Foxp3 + CD25 + T reg . ( G ) Functional analysis: after tumor cell inoculation, mice were treated with RNA-LPX at d3, d6, d10 and d13 p.t.i., mice were sacrificed at d14 for an ex vivo stimulation assay with PMA/Ionomycin ( H ) qRT-PCR was done to determine fold-change expression of cytokine RNA mix-treated normalized to irrelevant RNA LPX-treated lung samples (n=5 per group indicated in rows) for the indicated cytokines and chemokines.
Techniques Used: Injection, Flow Cytometry, Two Tailed Test, Functional Assay, Ex Vivo, Quantitative RT-PCR, Expressing
Figure Legend Snippet: Experimental design: BALB/c mice (n=5 per group) were injected i.v. with CT26 tumor cells; cytokine RNA mix or irrelevant RNA was administered i.v. at d3, d6 and d10 post tumor cell injection, mice were sacrificed at d11, lungs were collected and pooled at same ratios before sorting of CD45 + cells. CD45 + cells were subjected to scRNAseq. ( A,B ) Uniform manifold approximation and projection (UMAP) of 22 assigned clusters ( A ) and cell type frequencies ( B ) of CD45 + cells isolated from the lungs of cytokine RNA mix-treated versus irrelevant RNA-treated mice. ( C ) Effector function visualized as bubble plot. ( D ) Selected differentially expressed genes in cytokine RNA mix-treated versus irrelevant RNA-treated samples are shown as average log2 fold change. Note only significantly expressed values (p ≤ 0.05) are shown in colouring (blue = downregulated, red = upregulated), non-significant values are set to “0”/white.
Techniques Used: Injection, Isolation
Figure Legend Snippet: ( A ) Experimental design for ( B-C; CT26 tumor model) and ( E; CT26 B2M k.o. tumor model); n=15 BALB/c mice per group. Depletion or blocking antibody treatment was started 2 days prior to RNA-LPX treatment to ensure depletion before treatment start. ( B, C ) Survival according to termination criteria. ( D ) Experimental design and survival in CT26B2M k.o. or CT26gp70 k.o. tumor cells i.v. tumor model, n=15 mice per group. ( E ) BALB/c mice injected i.v. with CT26B2M k.o and depletion/neutralization antibodies were applied as shown in ( A ). Note that data in ( E ) were generated within the same experiment, irrelevant RNA + isotype mix as well as cytokine mix RNA + isotype mix refers to the same groups in all 3 plots. Survival was analyzed via Mantel-Cox logrank test. For ( B ) and ( C ), groups 1 and 2 were furthermore compared via logrank test with emphasis on early and late differences, ( B ) ## Logrank test with emphasis on late differences ((rho=0, lambda=1): group 1 vs 2: p=0,00235; ( C ) # Logrank test with emphasis on early differences (rho=1, lambda=0): group 1 vs 2: p=0,0378.
