Analysis of NDRG2 gene promoter methylation in PA samples. a Methylation frequency (%). b Hormone distribution of PAs in methylated and unmethylated NDRG2 promoter groups. PRL – prolactin, IGF-1 – insulin-like grow factor 1, GH – growth hormone, ACTH – adrenocorticotropic hormone, multiple – PAs secreting more than one hormone, NS – non-secreting PAs. c Representative MS-PCR for NDRG2 in PA samples. M indicates amplification of methylated alleles, U unmethylated alleles. M cont. – positive methylation control (Standard Bisulfite Converted Universal Methylated Human DNA), U cont. – negative methylation control (normal human peripheral lymphocytes), H2O – water control, I-VI designate PA samples
