Project description:41 lung adenocarcinoma from never-smokers hybridized on Illumina SNP arrays on 13 HumanCNV370-Quadv3 chips. High-resolution array comparative genomic hybridization analysis of lung adenocarcinoma in 41 never smokers for identification of new minimal common regions (MCR) of gain or loss. The SNP array analysis validated copy-number aberrations and revealed that RB1 and WRN were altered by recurrent copy-neutral loss of heterozygosity.The present study has uncovered new aberrations containing cancer genes. The oncogene FUS is a candidate gene in the 16p region that is frequently gained in never smokers. Multiple genetic pathways defined by gains of MYC, deletions of RB1 and WRN or gains on 7p and 7q are involved in lung adenocarcinoma in never smokers. A 'Cartes d'Identite des Tumeurs' (CIT) project from the French National League Against Cancer (http://cit.ligue-cancer.net) 41 samples hybridized on Illumina SNP arrays.

Project description:In order to determine the effect of neoR gene in Q175 locus, miRNASeq was performed to compare the transcriptional signatures of zQ175 knock-in neo-in (z_Q175 KI) (CHDI-81003003) and zQ175 KI neo-out (Z_Q175 (neo -) KI) (CHDI-81003019) mouse lines. The z_Q175 KI is a knock-in mouse line with humanized exon 1 (190-200 pure CAG repeats) derived from Q140 KI colony. It contains floxed neo cassette upstream of exon 1. The Z_Q175 KI (neo -) KI was generated by crossing the Z-Q175 KI line with a zp3-cre transgenic line to delete out the neo cassette.
