BACKGROUND: Long non-coding RNAs (lncRNAs) have been proved to act as key
molecules in cancer development and progression. Dysregulation of lncRNAs is
discovered in various tumor tissues and cancer cells where they can serve as
oncogenes or tumor suppressors. Long non-coding RNA HOXD-AS (HOXD cluster
antisense RNA 1) has recently been identified to be involved in the development
of several cancers including neuroblastoma, adenocarcinomas and breast cancer.
However, the role of HOXD-AS1 in bladder cancer remains unknown. METHODS: The
synthetic tetracycline-controllable shRNA was used to modulate the level of
HOXD-AS1 by adding different concentrations of doxycycline (dox). RT-qPCR was
used to detect the expression level of HOXD-AS1. Cell proliferation was
determined by CCK-8 assay and EdU incorporation experiment when HOXD-AS1 was
knocked down. We used wound-healing assay for detecting the effect of HOXD-AS1 on
cell migration. Eventually, cell apoptosis was determined by caspase 3 ELISA
assay and flow cytometry assay. RESULTS: In this study, we found that the
expression level of HOXD-AS1 was significantly increased in bladder cancer
tissues and cells. Furthermore, high expression of HOXD-AS1 was significantly
related to tumor size, histological grade and TNM stage. In vitro assays
confirmed that knockdown of HOXD-AS1 suppressed cell proliferation/migration and
increased the rate of apoptotic cell in bladder cancer cells. At last, we used
the important element of synthetic biology, tetracycline(tet)-controllable
switch, to construct tet-controllable shRNA vectors which can modulate the
expression of HOXD-AS1 in a dosage-dependent manner. CONCLUSIONS: Our research
suggested that high expression of HOXD-AS1 may be involved in the bladder cancer
carcinogenesis through inhibiting the phenotypes and activating endogenous
cancer-related molecular pathways. Therefore, HOXD-AS1 may act as an oncogene and
provide a potential attractive therapeutic target for bladder cancer. In
addition, the synthetic tetracycline-controllable shRNA may provide a novel
method for cancer research in vitro assays.
