目的:观察不同中医治法对大鼠肝癌UBE2D2表达的调控差异,以及UBE2D2在人肝癌细胞增殖中的作用。方法:采用DEN诱发大鼠肝癌,分别经中药健脾益气、清热解毒、活血化瘀等治疗后,Affy-metrix rat 230A GeneChip arrays检测肝癌组织UBE2D2表... 目的:观察不同中医治法对大鼠肝癌UBE2D2表达的调控差异,以及UBE2D2在人肝癌细胞增殖中的作用。方法:采用DEN诱发大鼠肝癌,分别经中药健脾益气、清热解毒、活血化瘀等治疗后,Affy-metrix rat 230A GeneChip arrays检测肝癌组织UBE2D2表达的差异;设计2个人UBE2D2基因siRNA靶点,将重组质粒经脂质体转入SMMC-7721人肝癌细胞株,MTT法检测细胞生长增殖情况、Realtime-PCR检测该基因的表达差异。结果:芯片结果显示,UBE2D2基因在大鼠肝癌形成后表达显著增加,不同中医治法对其具有不同程度的下调作用,其中健脾理气法下调作用较明显;采用MTT法筛选到1个UBE2D2基因RNA干扰有效靶序列,转染6 d后细胞的生长增殖得到了明显的抑制(与阴性对照组相比,P<0.01);实时荧光定量PCR检测表明,转染6 d后该基因的表达明显降低。结论:UBE2D2基因的高表达与肝癌细胞恶性增殖有关,而中药健脾理气治法对其具有下调作用。 展开更多

The modification of proteins with ubiquitin is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation.Ubiquitin-conjugating enzyme E2 D2 is a protein that is encoded by the UBE2D2 gene.Here,we report a lamprey(La UBE2D2)gene which contained 441-bp open reading frame(ORF)encoding 147 amino acids with a typical UBC domain.Real-time PCR assay showed that the highest expression of the protein in adult lamprey was in the leukocytes,the lowest expression was in the skin,kidney and liver.The high conservation in amino acid sequence of the La UBE2D2protein with the UBE2D2s from Homo sapiens,Danio rerio,Oreochromis niloticus and Takifugu rubripes,implied that it had similar function with UBE2D2proteins from other species. 展开更多
