癌症干细胞(CSC)假说暗示了靶向CSC群体的新治疗方法的发展。表征调控CSC活性的途径将促进靶向治疗的发展。我们最近报道了ALDH1的酶活性,如通过ALDELFUOR测定所测量的,可用于分离原发性肿瘤和细胞系中的正常和恶性乳腺干细胞。在这项研究中,利用肿瘤球测定,我们已经证明了类维生素A信号在乳腺CSC自我更新和分化的调节中的作用。利用基因集富集分析(GSEA)算法,我们鉴定了与类维生素A信号传导相关的基因集和途径。这些途径调节乳腺CSC生物学,并且它们的抑制可以提供靶向乳腺CSC的新的治疗方法。
The cancer stem cell (CSC) hypothesis implicates the development of new therapeutic approaches to target the CSC population. Characterization of the pathways that regulate CSCs activity will facilitate the development of targeted therapies. We recently reported that the enzymatic activity of ALDH1, as measured by the ALDELFUOR assay, can be utilized to isolate normal and malignant breast stem cells in both primary tumors and cell lines. In this study, utilizing a tumorsphere assay, we have demonstrated the role of retinoid signaling in the regulation of breast CSCs self-renewal and differentiation. Utilizing the gene set enrichment analysis (GSEA) algorithm we identified gene sets and pathways associated with retinoid signaling. These pathways regulate breast CSCs biology and their inhibition may provide novel therapeutic approaches to target breast CSCs.
