AbstractThe leucine-rich repeat-containing G-protein-coupled receptor 6 (LGR6) is considered to be a stem cell marker in many normal tissues and promotes tissue development, regeneration, and repair. LGR6 is also related to the initiation and progression of some malignant tumors. However, the role of LGR6 in cervical cancer has not been reported. Here, immunohistochemistry and western blotting showed that LGR6 was significantly upregulated in cervical cancer, compared with the normal cervix. By analyzing The Cancer Genome Atlas database, LGR6 was found to be correlated with a poor prognosis of cervical cancer. Then, a small population of LGR6high cells isolated by using the fluorescence-activated cell sorting exhibited enhanced properties of cancer stem cells including self-renewal, differentiation, and tumorigenicity. Moreover, RNA sequencing revealed that LGR6 was correlated with the Wnt signaling pathway and TOP/FOP, reverse transcription-PCR, and western blotting further proved that LGR6 could activate the Wnt/β-catenin signaling pathway. Interestingly, LGR6 upregulated the expression of TCF7L2 by activating the Wnt/β-catenin pathway. Then, TCF7L2 combining with β-catenin in the nucleus enhanced LGR6 transcription by binding the promoter of LGR6, which further activated the Wnt signaling to form a positive feedback loop. Thus, our study demonstrated that LGR6 activated a novel β-catenin/TCF7L2/LGR6-positive feedback loop in LGR6high cervical cancer stem cells (CSCs), which provided a new therapeutic strategy for targeting cervical CSCs to improve the prognosis of cervical cancer patients.

The Wnt-signaling pathway regulates various biological processes, such as embryonic development, self-renewal, proliferation, differentiation and migration of stem cells. The Wnt-signaling is involved in tumor progression by aberrant activation in stem-like cells, called cancer stem cells, in different kinds of tumor, including multiform glioblastoma. The Wnt-signaling promotes stemness, invasion, metastasis, therapeutic and immune resistance of cancer stem cells in multiform glioblastoma. To summarize, targeting the Wnt-signaling pathway as an oncogenic driver is the future hope for effective therapy of glioblastoma for which current standard therapy is not effective.In this review, we focused on functions of the Wnt-signaling in cancer stem cells and involvement of the Wnt-signaling pathway in gliomagenesis.
