RNA sequencing of genetically engineered mouse model lung tumors and normal mouse lung.

Genetically engineered mouse models (GEMM) of cancer are powerful tools to study multiple aspects of caner biology. We developed a novel GEMM for lung squamous cell carcinoma (LSCC) by genetically combining overexpression of Sox2 with loss of Lkb1: Rosa26LSL-Sox2-IRES-GFP;Lkb1fl/fl (SL). We compared gene expression profiles of SL lung tumors with normal mouse lung tissue, mouse lung adenocarcinoma (LADC) tumors from KrasLSL-G12D/+;Trp53fl/fl (KP), mouse LSCC tumors from Lkb1fl/fl;Ptenfl/fl (LP) model as well as Lenti-Sox2-Cre Lkb1fl/fl. Overall design: Tumors were isolated from formalin-fixed paraffin-embedded (FFPE) tissue samples by microdissection and nucleic acid isolation was performed followed by single-read or paired-end RNA sequencing.
