Figure 2. The chromosomal regions with copy number variations for patients with MDR gene locus deletions (A) and patients without deletions.
(B). Blue (upper horizontal dotted) and red (under horizontal dotted) are regions of gains (amplifications) and losses (deletions), respectively. Abscissa – cytobands (n = 852), axis of ordinates – frequency of patients bearing CNV in tumor (%). For CNV study microarray analysis was performed using high density microarray platform Affymetrix (USA) CytoScan™ HD Array.
