Fig. 4. The biological function of HOTAIR in GC cells.

Fig. 4

a Two HOTAIR siRNAs were transfected into GC cells separately. 48 h after transfection, total RNA was extracted and the HOTAIR level was determined by qRT-PCR. In vitro cell migration and invasion assay were processed using traditional transwell plate. b MTT assay was used to determine the relative cell viability. c The numbers of apoptotic cells in HOTAIR knocked down GC cells were counted by flow cytometry after annexin V-FITC and PI staining. Results were analyzed by One-way ANOVA and p < 0.05 was considered as significant. *P < 0.05, **P < 0.01.
