Cancer stem cells has been widely investigated due to its essential role in cancer progression and drug resistance. Here, we try to find a new therapeutic target for cervical cancer stem cells.
We detected ALDH1A1-associated miRNAs expression in our isolated tumorspheres and their corresponding parental cells. Sphere formation assay was also used to determine stemness after cells were manipulated with miR-23b plasmid or miR-23b inhibitor.
We found that miR-23b was under-expressed in cervical cancer stem cells to maintain high levels of ALDH1A1. Introduction of miR-23b into cervical cancer cells could alter stemness and cisplatin sensitivity.
miR-23b plays key role in maintaining stemness of cervical cancer stem cells and can be developed as therapeutic target to better fight against cervical cancer.
癌症干细胞因其在癌症进展和耐药性中的关键作用而受到广泛研究。在此,我们试图寻找一种针对宫颈癌干细胞的新治疗靶点。
我们检测了在我们分离的肿瘤球及其相应亲代细胞中与醛脱氢酶1家族成员A1(ALDH1A1)相关的微小RNA(miRNA)表达。在用miR-23b质粒或miR-23b抑制剂处理细胞后,还使用成球试验来确定干性。
我们发现miR-23b在宫颈癌干细胞中低表达,以维持高水平的ALDH1A1。将miR-23b导入宫颈癌细胞可改变干性和顺铂敏感性。
miR-23b在维持宫颈癌干细胞干性中起关键作用,可作为治疗靶点开发,以更好地对抗宫颈癌。
