    • 摘要: Progression,relapse,and therapy resistance are the most challenging features of cancer therapy that have been postulated to be driven by Cancer Stem Cell(CSC)population.This enigmatic subpopulation of cancer cells has therefore emerged as promising therapeutic candidate.We earlier reported enrichment of CSC-like side population(SP)with increasing resistance towards Cisplatin and Paclitaxel either alone or in combination in epithelial ovarian cancer(EOC)cells.This SP population is a small proportion of the total population of cancer cells characterised with high expression of drug transporters,a unique feature of stem cells and thereby can be isolated through their efflux properties of DNA binding dyes.While the bulk non-SP(NSP)population of the cancer cells lack overexpression of the drug transporters and thus can be identified as the dye containing population.In this study,we show that increased expression of Runt related transcription factor 1(RUNX1)maintains undifferentiated state of CSC-like SP cells through upregulation of inhibitors of DNA binding/differentiation genes(ID1 and ID3)in late cisplatinpaclitaxel resistant cells.Higher RUNX1 expression was found to correlate with decreased median overall survival and disease-free survival in The Cancer Genome Atlas(TCGA)data set of high grade serous ovarian cancer(HGSOC)patients.The protein-protein interaction network analysis of 397 upregulated genes in RUNX1-high samples of TCGA data show significant enrichment of pathways known to negatively regulate CSC differentiation.Intriguingly RUNX1 inhibition not only induces CSC differentiation but also downregulates anti-apoptotic protein BCL2 in both SP and NSP cells and potentiates cytotoxic effects of Cisplatin-Paclitaxel in chemoresistant EOC cells.Inhibition of BCL2 through Venetoclax treatment,a small molecule BH3 mimic,sensitized these cells to platinum taxol treatment.Altogether,our data reveal new regulatory roles by RUNX1 to modulate CSC differentiation via ID1 and ID3 and to promote chemoresistance through BCL2 upregulation.

    • 摘要: 【据《Hepatol Int》2019年6月报道】题:正反馈激活CCN2-MAPK-Id1信号环促肝癌奥沙利铂耐药的实验研究(作者Liao X等)肝细胞癌在全球范围的发病率呈上升趋势,是全球第二大肿瘤致死病因。化疗作为晚期肝细胞癌患者综合治疗的重要手段之一,耐药的出现严重减低了肿瘤治疗效果。因此寻找化疗的潜在耐药机制并进行相关干预对于提高肝细胞癌疗效具有重要的意义。

    • 摘要: 目的:探讨分化抑制因子1(ID1)在结直肠癌肝转移中的意义及其作用机制。方法:收集2012年8月至2017年9月汕头大学医学院第一附属医院结直肠腺癌患者临床样本共50例,通过免疫组化方法检测ID1在发生肝转移的结直肠癌组织与未发生肝转移的结直肠癌组织的表达差异;通过过表达手段,检测ID1对RKO细胞上皮-间质转化的相关标志物的影响。结果:与癌旁正常组织相比,结直肠癌组织中ID1表达上调;与没有发生肝转移的癌组织相比,发生肝转移的癌组织中ID1表达上调,差异均具有统计学意义(均P<0.01)。在人结肠癌细胞系RKO中过表达ID1后,Twist和磷酸化的STAT3表达上调。结论:ID1可能是结直肠癌中潜在的促癌基因,ID1激活STAT3信号通路,引起Twist转录增强,可能与结直肠癌的肝转移相关。

    • 摘要: 目的 探讨分化抑制因子1(Id-1)和转录因子E2-2(E2-2)对PI3K/Akt通路的影响情况,并明确其在内皮祖细胞(EPCs)增长中的作用.方法 采用免疫共沉淀检测Id-1及E2-2是否存在相互作用.在EPCs细胞模型中,过表达及干扰Id-1及E2-2,采用CCK-8法检测细胞增长情况,RT-PCR和Western blot技术检测PI3K及Akt表达水平.结果 免疫共沉淀检测发现,Id-1及E2-2之间存在蛋白-蛋白相互作用.过表达Id-1可显著下调E2-2表达水平,上调PI3K/Akt表达水平,细胞增长能力增强;过表达E2-2后PI3K/Akt表达降低,细胞增长减弱;共转染Id-1及E2-2则发现,二者可协同影响PI3K/Akt表达水平.结论 Id-1和E2-2之间存在相互作用,Id-1对PI3K/Akt起促进作用,而E2-2则发挥抑制效应,二者协同调控PI3K/Akt信号通路,进而影响EPCs的增长.%Objective To explore the associations between Id-1,E2-2 and PI3K/Akt pathway for increase of EPCs. MethodsIn the EPCs cell model,we used immune coprecipitation test to detect the association between Id-1 and E2-2.We overexpressed orinterfered Id -1 or E2 -2,and used CCK 8 method to detect cell increase;RT -PCR and Western blotting technique to detectexpression of PI3K,and Akt levels. Results Immune coprecipitation test found that there was protein-protein interaction betweenId-1 and E2-2. Compared with the control group,overexpression of Id -1 could decrease the E2-2 expression level,and increase theexpression of PI3K/Akt,which lead to inhanced cell proliferation ability. Overexpressing E2-2 reduced the expression of PI3K/Aktand cell proliferation. Co-transfection Id-1 and E2-2 showed that both proteins could influence the expression of PI3K/Akt levelsynergetically. Conclusion There was protein-protein interaction between Id-1 and E2-2;Id-1 has positive regulatory role for PI3K/Akt while E2-2 has a negative regulatory role. The Id-1 and E2-2 could coordinate to control the PI3K/Akt signal pathway,thusaffecting the increase of the EPCs.
