Mouse syngeneic model RNAseq sequencing

Mouse syngeneic models serve as indispensable tools for elucidating tumor-immune interactions and assessing immunotherapy efficacy. In this study, we first conducted a comprehensive evaluation of six label-free protein quantification pipelines across 12 mouse syngeneic models, revealing that data-independent acquisition (DIA) significantly outperforms data-dependent acquisition (DDA) in terms of data coverage, reproducibility, and inter-model discrimination. We next performed an integrative multi-omics analysis to uncover molecular mechanisms associated with treatment response. Our analysis identified Dnmt3a and Igf2r, which are correlated with resistance to immune checkpoint inhibitors (ICIs), and highlighted key pathways including interferon signaling and oxidative phosphorylation that distinguish responders from non-responders. To facilitate broader research applications, we have developed an interactive web resource that shares our multi-omics datasets and analytical results, equipped with user-friendly tools for further exploration. It is freely accessible at https://muscreen.crownbio.com/syngeneic_omics. This resource aims to accelerate preclinical research and contribute to the development of personalized cancer therapies.
