LX2 cells are activated in a co-cultured system with THP-1 cells. (A) miR-152 expression in the LX2 cells during culture activation was detected by RT-qPCR. Data are presented as the mean ± standard deviation. (B) α-SMA mRNA expression in LX2 cells was analysed with RT-qPCR. Each value represents the mean ± SD of 3 experiments. (C) Albumin mRNA expression in LX2 cells was examined using RT-qPCR. Each value represents the mean ± SD of 3 experiments. (D) Western blot analysis of α-SMA and albumin in stimulated LX2 cells. The housekeeping protein GAPDH was used as loading controls for the western blot analysis and protein normalization. miR, microRNA; SD, standard deviation; RT-qPCR, reverse transcription quantitative polymerase chain reaction; α-SMA, α-smooth muscle actin; NC, negative control.
