CircRNA通过越来越多的报道的调控机制在各种恶性肿瘤中发挥关键作用,包括circRNA和microRNA(miRNAs)之间的经典海绵机制。我们进行了生物信息学分析,并确定circTLK 1作为恶性脉络膜进展的调节因子。此外,我们观察到circTLK 1在脉络膜细胞和组织中显示高表达,而circTLK 1干扰抑制脉络膜细胞增殖和侵袭。此外,circTLK 1直接与miR-16- 5 p相互作用,miR-16- 5 p先前已显示抑制脉络膜,并且circTLK 1敲低抑制Smad 3表达。染色质免疫沉淀测序进一步证明Smad 3通过与TLK 1相互作用而作为正调控因子发挥作用,从而介导circTLK 1/miR-16- 5 p/Smad 3正反馈轴。综上所述,我们的研究结果表明,破坏circTLK 1/miR-16- 5 p/Smad 3正反馈通路,特别是通过Smad 3抑制剂SIS 3,可能是一种有前途的治疗策略。
CircRNAs play crucial roles in various malignancies via an increasing number of reported regulatory mechanisms, including the classic sponging mechanism between circRNAs and micro RNAs (miRNAs). We performed bioinformatic analyses and identified circTLK1 as a regulator of malignant chordoma progression. Moreover, we observed that circTLK1 showed high expression in chordoma cells and tissues, while circTLK1 interference suppressed chordoma cell proliferation and invasion. In addition, circTLK1 directly interacted with miR-16-5p, which has previously been shown to repress chordoma, and circTLK1 knockdown suppressed Smad3 expression. Chromatin immunoprecipitation sequencing further demonstrated that Smad3 acts as a positive regulator by interacting with TLK1, thereby mediating the circTLK1/miR-16-5p/Smad3 positive feedback axis. Taken together, our findings suggested that the disruption of the circTLK1/miR-16-5p/Smad3 positive feedback pathway, particularly via the Smad3 inhibitor SIS3, could be a promising therapeutic strategy.
