Currently, lncRNA forkhead box P4 antisense RNA 1 (FOXP4-AS1), which is a lncRNA related to tumours, is believed to participate in the occurrence of tumours and promote tumour proliferation, invasion, and migration; thus, its upregulation is usually related to tumour grade and poor prognosis [7, 8]. The gene discussed is FOXP4; the disease is neoplasm.
