In the NPC cell lines,loss of BLU expression correlated with hypermethylation of the 20 CpG sites in the 5′ region of BLU(approximately -292bp to -23bp upstream the translation start site)as revealed by bisulphite sequencing. Expression of the gene was restored aftertreatment with 5-aza-2-deoxycytidine in CNE2, suggesting that repression of BLUtranscription might at least be partially mediated by promoter methylation.

结果显示,BLU基因翻译起点ATG上游-292--23bp区间内的20个CpG位点在5例细胞系中均被完全或者部分甲基,与基因的表达缺失呈负相关关系;去甲基试剂5-Aza-CdR处理CNE2后基因表达部分恢复,说明甲基至少是引起BLU基因转录抑制的部分原因。

17Mm x3mm and ψ15mmx2.5mm coin type blushless motors are respectively developed in 2005 and 2006. MIRDC expects to develop a ψ12mm x 2.5mm coin type blushless motors in 2007.
