GNA15 and lung carcinoma: Since, loss of heterozygosity (LOH) plays an important role during the inactivation of tumor suppressor genes (TSG), we also searched for LOH (segmented genotype intensity) at GNA15/16 locus (Gα16) on our lung cancer cell lines using the CONAN (Copy Number Analysis) tool (http://www.sanger.ac.uk/cgi-bin/genetics/CGP/conan/) from the Sanger Cancer Genome Project.
