From: Arsenic-related DNA copy-number alterations in lung squamous cell carcinomas
Comparison of copy-number alterations (CNAs) frequency at chromosome region 3q for lung squamous cell carcinomas (SqCCs) derived from arsenic-exposed smokers and never smokers. Genome profiles for 22 cases of arsenic-exposed lung SqCC biopsies (12 from current and ex-smokers and 10 from never smokers) were compared at chromosome region 3q and visualised using SeeGH software. Frequency of CNAs results for smokers and never smokers have been overlaid in this figure. Results for smokers are represented in red; while results for never smokers are shown in green (yellow denotes a region exhibiting similar alteration status in both groups). The magnitude of green and red bars represents percentage of samples exhibiting corresponding alteration (0–100%, with blue vertical lines representing 50% frequency). DNA gains and losses are displayed to the right and left of each chromosome, respectively.
