HOXA3 and neoplasm: In these cases, HOXA-AS2 modulates different miRNA-related pathways, such as miR-509-3p/BTN3A1, miR-15a-5p/HOXA3, miRNA-302c-3p/ZFX, miR-519/HIF-1α/PD-L1, miR-124-3p/E2F3, miR-216a-5p, miR-125b/Smad2, and miR-520d-3p/KIAA1522/IGF2BP3, to promote tumor progression (Table 3 and Fig. 4).
