Non-coding RNAs (ncRNAs) are a newly discovered functional RNA different from
messenger RNA, which can participate in regulating the occurrence and
development of tumors. More and more research results show that ncRNAs
can participate in the regulation of gastric cancer (GC) radiotherapy response,
and its mechanism may be related to its effect on DNA damage repair, gastric
cancer cell stemness, cell apoptosis, activation of epidermal growth factor
receptor signaling pathway, etc. This article summarizes the relevant
mechanisms of ncRNAs regulating the response to radiotherapy in gastric
cancer, which will be directly important for the introduction of ncRNAs
particularly microRNAs (miRNAs), long non-coding RNAs (lncRNAs) and circular
RNAs (circRNAs) into clinical medicine as biomarkers and therapeutic targets.
