Moreover, we assessed the correlation between CCND1 mRNA and miR-134 expression in 39 lung cancer tissues, and results indicated expression of CCND1 mRNA and miR-134 showed a remarkably inverse correlation as calculated by Pearson correlation (r2=0.2021, P =0.0041) (Figure 2B). The gene discussed is CCND1; the disease is lung carcinoma.
