Fig. 1From: Transcription factor CCAAT/enhancer binding protein alpha up-regulates microRNA let-7a-1 in lung cancer cells by direct bindingExpression of C/EBPα and let-7a-1. Detection of (a) C/EBPα protein (30 μg) expression and (b) let-7a-1 was performed by western blotting and quantitative real-time polymerase chain reaction, respectively, in Hela, A549 and H1299 cells. Data are represented as means ± standard deviations from three independent tests. *P < 0.05Back to article page
