Abstract
Background
As a member of non-coding RNAs family, long non-coding RNAs’ functions in cancer needs to be further investigated. It has been indicated that the functions of Hox transcript antisense intergenic RNA (lncRNA: HOTAIR) include reprogramming chromatin organization and promoting tumor metastasis such as breast and colorectal tumor. The aim of this study is to investigate the functions of Hox in gastric cancer.
Methods
In the present study, the expression level of HOTAIR was determined by quantitative reverse transcription polymerase chain reaction (qRT-PCR), 20 gastric cancer tissues and 20 normal tissues was included. All clinical data were analyzed retrospectively. The CCK-8 and colony formation assay was used to identify if the knockdown of HOTAIR have an influence on gastric cancer cell lines.
Results
Compared with normal tissues, higher expression level of HOTAIR was found in gastric cancer tissues. Dioscin inhibits proliferation of the three gastric cancer cell lines and decrease HOTAIR expression.
Conclusions
The expression of HOTAIR is up regulated in gastric cancer and gastric cancer cell lines, dioscin inhibits the proliferation of three gastric cancer cell lines and the anti-tumor effect of dioscin may partly depend on the down regulation of HOTAIR.
