WNT3 and esophageal squamous cell carcinoma: demonstrated that circRNA_100367 regulates the radiation sensitivity of esophageal squamous cell carcinomas through the miR‐217/Wnt3 pathway.[36] Another study reported that the circRNA TUBD1, which is significantly upregulated in irradiated LX‐2 Cells, acts as an miR‐146a‐5p sponge to influence the viability and pro‐inflammatory cytokine production of LX‐2 Cells through the TLR4 Pathway.[37] However, there are no reports on the role of circRNAs in radiation‐induced abscopal effects.
