A genetic-metabolic axis for metastatic liver organotropism


ABSTRACT: To generate CRISPR/Cas9 knockout screen, we used mouse Kinome CRISPR Knockout Library (Brie) (Addgene # 75316) purchased from addgene. The mouse kinase sgRNA pool includes 2,852 sgRNAs targeting 713 kinase genes and 100 control non-targeting sgRNAs. Cas9 expressing HCmel12 melanoma cells were edited for 14 days, and tumor cells were injected for metastasis screening studies. RNA-seq data: HCmel12 melanoma cells and CRISPR knockout HCmel12 melanoma cells - Pip4k2c KO were treated for 4 hours with insulin. Then cells were lysed in RLT buffer and used to perform mRNA profiling. We performed single-cell RNA-sequencing (scRNA-seq) of eight mice with concurrent liver and lung metastasis. A total of 95,606 cells expressing 19,624 genes were included for downstream analyses. Bulk RNA-sequencing analysis of 15 human melanoma liver metastasis samples from FFPE sample. Tumor areas were macro-dissected and RNA was extracted using Qiagen kit All Prep DNA/RNA FFPE Kit (Catalog Number 80234), concentration was quantified using Qu-bit and stored at-80 °C until use.
