Effect of HOTAIR overexpression on HIF-1α expression in HeLa and C33A cells exposed to radiation. (a) The protein level of HIF-1α in HeLa and C33A cells was detected. (b) The expression of HOTAIR in HeLa and C33A cells was detected. The data are represented as mean ± SD. **vs control cells, P < 0.01; ##vs cells irradiated with a dose of 2 Gy and transfected with Ad-GFP, P < 0.01. All the experiment performed in triplicate
