Expression of Dnmt1, demethylase, MeCP2 and methylation of tumor-related genes in human gastric cancer

Figure 2 Density of bands from RT-PCR in each lane normalized to the total RNA as determined by the density of bands in RT-PCR for β -actin. Assuming β -actin was 4 562.39 units (pixels of brightness), the calculation [4 562.39/(density of actin)] × (density of each gene) equals each gene normalized to β -actin. Data shown are representative of three separate experiments. ^aP < 0.05.
