RNAseq carcinogen induced signatures in lung adenocarcinoma cell lines
FVB, Balb/c, and C57BL/6 mice received the tobacco carcinogens urethane (Sigma Aldrich, U2500) intraperitoneally (1g/Kg in 100 µl phosphate-buffered saline) or diethylnitrosamine (200 mg/kg) (Sigma Aldrich, N0756). Carcinogen induced lung adenocarcinoma murine cell lines generation| Ten months post first carcinogen (urethane, DEN) exposure mice were sacrificed, lung tumours were dissected from surrounding healthy lung parenchyma under sterile conditions, were halved, one half was processed for histology and the other half was chopped into 1 mm pieces and seeded to cell culture dishes. Cells were cultured under standard conditions outlined below. When adenocarcinoma was diagnosed for a given tumour, its corresponding culture was passaged in vitro over a period of 18 months and 60 passages, whichever occurred first. After gene expression and mutational signature extraction, the signature were compared with human lung adenocarcinoma RNAseq results. Overall design: Compare differential gene expression between naïve mouse lung cells and mouse adenocarcinoma cell lines. Alignment of sequencing traces for exploration and visualization of transcripts alteration and single nucleotide variation.
