Project description:We investigate the single-cell landscape of the inflammatory mouse tumor model MC38, a C57BL/6 tumor cell line derived from colon adenocarcinoma. MC38 (diluted in HBSS and matrigel) was inoculated in the right unilateral flank (in the border of positions B2 and B3) of C57BL/6 mice (ref Study 16-3384 AV). Tumors were taken one day after group-out (average 150-250 mm3 at day 0), approximately 14-19 days. Tissues were dissociated and flow sorted accordingly to obtain the following groups for 10x Chromium 5' Gene Expression Profiling. Our results indicate that the degree of clonal expansion is correlated with expression of T cell exhaustion markers, and that T cells with strong exhaustion phenotype also express high levels of activation markers, such as interferon gamma.

Project description:MC38 tumors resistant to anti-PD-1 treatment (MC38-resistant) were generated through serial in vivo passaging, and global gene expression analysis was used to compare resistant and parental tumors. MC38 and MC38-resistant tumors exhibited widespread changes in global gene expression.
Project description:We designed a novel intratumoral (IT) IL-12 mRNA therapy to promote local IL-12 tumor production whilst mitigating systemic effects. A single IT dose of mouse (m)IL-12 mRNA induced IFNγ and CD8+ T cell-dependent tumor regression in multiple syngeneic mouse models including MC38-R, and animals with a complete response demonstrated immunity to re-challenge. In order to further investigate the impact of mIL-12 mRNA on the MC38-R TME, we performed tumor transcriptomic evaluation 24h and 7 days after a single IT dose of 0.5 micrograms IL-12 or control mRNA. mRNA was isolated from snap-frozen syngeneic tumors using an RNeasy mini kit (Qiagen) and quantified on the Affymetrix mouse 430 2.0 microarray.

MC38 (diluted in HBSS and matrigel) was inoculated in the right unilateral flank (in the border of positions B2 and B3) of C57BL/6 mice (ref Study 16-3384 AV). Draining lymph nodes were taken one day after group-out (average 150-250 mm3 tumor size at day 0), approximately 14-19 days. Draining lymph nodes were dissociated and flow sorted accordingly to obtain the cells for 10x Chromium 5' Gene Expression Profiling and TCR sequencing.
