Functional description
OBJECTIVES: Cervical cancer is an aggressive malignant tumour and causes high mortality in women. LncRNA HOXA-AS2 is a tumour promoter in many cancers. The current work was designed to elucidate the functions of HOXA-AS2 in cervical cancer and the underlying regulatory mechanism. METHODS: qRT-PCR was conducted to reveal RNA levels. A FISH assay was conducted for the identification of the subcellular location of HOXA-AS2. MTT, EdU, Transwell and tube formation were used for detection of cell growth, migration and angiogenesis, respectively. In-vivo studies were conducted to reveal the role of HOXA-AS2 on transplanted tumour growth in mice. KEY FINDINGS: The HOXA-AS2 level was found high in tissues and cells of cervical cancer. Silencing of HOXA-AS2 restrained cell proliferation, migration and invasion. Angiogenesis of HUVECs was restrained after silencing HOXA-AS2. Additionally, HOXA-AS2 upregulated the BTN3A1 by interaction with miR-509-3p. BTN3A1 overexpression rescues the inhibitory effect of silenced HOXA-AS2 on cell phenotypes in cervical cancer. Moreover, xenograft tumour growth in mice was suppressed by HOXA-AS2 depletion and was facilitated by BTN3A1 overexpression. CONCLUSIONS: HOXA-AS2 accelerates cellular progression in cervical cancer by the miR-509-3p/BTN3A1 axis.
