CSTF2 expression in lung cancer cells. a Log2 results for ratio of the gene expression level between cancer and para-carcinoma tissue of 93 RNA transcription and translation related influential factors. Red colored bars represented the genes with significantly up-regulated expression (p < 0.01) in cancer tissue. Blue colored bars represented the genes with significantly down-regulated expression (p < 0.01) in cancer tissue. b Western blot analysis showing the CSTF2 protein levels of lung cancer cell lines and normal lung HFL1 cell line. c Graph showing the higher mRNA expression of CSTF2 detected in the H460 compared to HFL1 cells. Data represents the average of three independent q-RT-PCR experiment. d Log2 results for ratio of CSTF2 gene expression detected in our clinical samples and summarized from TCGA database
