RESULTS: APC promoter 1A was methylated in NCI-H460 cells, and unmethylated in NCI-H446 and SPC-A1 cells. Hypermethylation was detected in all 5 CpG islands (687, 707, 714, 719, 726) of APC promoter 1A in NCI-H460 cells. The expression of APC in NCI-H460 cells was decreased by 26.04% of that in NCI-H446 cells and by 32.36% of that in SPCA1 cells. After treatment of 1, 5, 10, 15μmol/L 5-aza-dC, the expression of APC promoter 1A in NCI-H460 cells was enhanced by 4.59, 5.78, 9.58, 5.98 folds, respectively.

结果：SPC-A1和NCI-H446细胞APC甲基化阴性，NCI-H460细胞APC甲基化阳性；甲基化芯片检测Ncl-H460细胞在APC启动子1A 5个CpG位点均存在甲基化(687、707、714、719、726)，SPC-A1和NCI-H446甲基化阴性，荧光定量结果NCI-H460的APC转录较SPC-A1和NCI-H446有明显的下降，仅为二者平均的30.04%；经5-aza-dC脱甲基化作用后，NCI-H460细胞的APC表达增加了约5~10倍，其中10μmol/L浓度作用下，APC表达增加最多。

Results HPP1 gene was methylated in 37 of 52(71.2%) colorectal cancers and 12 of 21 (57.1%) adenomas cases. In contrast, HPP1 gene was unmethylated in all of the samples from healthy controls.

结果 结直肠癌粪便标本HPP1基因甲基化阳性率为71.2%(37/52)，腺瘤粪便标本为57.1%(12/21)，而正常粪便标本均为阴性。

Dna was extracted from 12 frozen tissues and 35 paraffin embedded tissues, then treated by sodium bisulfite and pcr amplified by specific primers for methylated versus unmethylated dna.

The gene chip detecting methylation changes of 3 CpG in promoter region of p16 gene was constructed by designing a pair of probes which contain one methylated and one unmethylated probes. This pair of probes was used to detect 3 consecutive sites of CpG island in p16 gene.

设计1组特殊荧光标记探针以构建1种检测p16基因启动子区3个CpG位点甲基化改变的芯片，特殊荧光标记探针包括1对非甲基化探针和甲基化探针，检测相邻的3个CpG位点甲基化的程度。

For The Methylation Assay, the readout is called beta, which is calculated from the fluorescent signal ratio of Cy3 to Cy 5, where all green signal means unmethylated and all red, fully methylated.

甲基化分析的结果称作β，是以荧光信号Cy3于Cy5之比计算得出的结果，如果全部都是绿色信号，表示未甲基化，而全为红色则表示完全甲基化。

And MSAP with 24 primer was used for analysis in Yesso scallops with orange/white muscle, it was showed that there were 46 loci which had differences in the degree of methylation between the population with orange muscle and the white, among of which 18 were methylated or semi-methlated loci, which may be related to the appearance of orange muscle.
