Figure Lengend Snippet: Ischaemic preconditioning effects on DNA methyltransferase activity and DNA methylation at gene promoters. ( A ) DNA methyltransferase activity of ischaemic preconditioning vs. non-ischaemic preconditioning at T1 ( n = 10 per group. ( B ) RT-PCR data for mRNA levels of the CCAAT enhancer binding protein delta (Cebpd) gene ( n = 10 per group). ( C ) Schematic diagram showing Cebpd genomic location, CpG island, and regions amplified with primers designed within CpG island and gene promoter region ( D ) MethylMiner quantitative PCR data showing relative promoter methylation for Regions 1 and 2 of the Cebpd gene ( n = 6 per group). ( E ) RT-PCR data for mRNA levels of the NFKB inhibitor alpha (Nfkbia ) gene ( n = 10 per group). ( F ) Schematic diagram showing Nfkbia genomic location, CpG island, and regions amplified with primers designed within CpG island and gene promoter region ( G ) MethylMiner quantitative PCR data showing relative promoter methylation for Regions 1 and 2 of the Nfkbia gene ( n = 6 per group). ( H ) RT-PCR data for mRNA levels of the Growth arrest and DNA damage inducible beta (Gadd45b) gene ( n = 10 per group). ( I ) Schematic diagram showing Gadd45b genomic location, CpG island, and regions amplified with primers designed within CpG island and gene promoter region ( J ) MethylMiner quantitative PCR data showing relative promoter methylation for Regions 1 and 2 of the Gadd45b gene ( n = 6 per group). ( K ) RT-PCR data for mRNA levels of the Jun proto-oncogene ( Jun ) gene ( n = 10 per group). ( L ) Schematic diagram showing Jun genomic location, CpG island, and regions amplified with primers designed within CpG island and gene promoter region ( M ) MethylMiner quantitative PCR data showing relative promoter methylation for Regions 1 and 2 of the Jun gene ( n = 6 per group). ( N ) RT-PCR data for mRNA levels of the Apolipoprotein L domain containing 1 ( Aplod1 ) gene ( n = 10 per group). ( O ) Schematic diagram showing Aplod1 genomic location, CpG island, and regions amplified with primers designed within CpG island and gene promoter region ( P ) MethylMiner quantitative PCR data showing relative promoter methylation for Regions 1 and 2 of the Aplod1 gene ( n = 6 per group). Data are shown as mean ± SEM. P -value was determined using an unpaired two-tailed t -test.
