Figure 4. Effect of HOTAIR on PKR expression; A, qRT-PCR revealed overexpression of HOTAIR promoted the expression of PKR; B, Western blotting analysis revealed overexpression of HOTAIR promoted the expression of PKR. Data are reported as means±SD. *P<0.05; **P<0.01 (ANOVA). HOTAIR: HOX antisense intergenic RNA; PKR: RNA-dependent protein kinase; qRT-PCR: quantitative real-time polymerase chain reaction.
