DARS-AS1 binds to DARS 5ʹUTR to regulate DARS mRNA stability. A Subcellular fractionation assays identified the cellular location of DARS-AS1 in HeLa and C33A cells treated with hypoxia. B FISH assays detected the co-existence of DARS-AS1 and DARS in HeLa and C33A cells treated with hypoxia. C Luciferase activity of DARS promoter in DARS-AS1-silenced HeLa and C33A cells treated with hypoxia was analysed. D Combination between DARS 5ʹUTR and DARS-AS1 in hypoxia-treated cells was confirmed using RNA pull down assay. E Stability of DARS mRNA in DARS-AS1-silenced cells treated with hypoxia in the presence of actinomycin D was analysed. Experimental procedures were repeated independently for three times. *P < 0.05, **P < 0.01.
