Fig. 6. Correlation analysis between lncRNA-MALAT1 expression and Cd concentration in Cd-exposed workers. Correlation analysis between lncRNA-MALAT1 expression and blood Cd concentration (A), urine Cd concentration (B) and urine β2-MG concentration (C). Blood lncRNA-MALAT1 expression was calculated by the ratio of its expression to that of β-actin. The urine cadmium concentration was normalized by urine creatinine (μg g–1 Cr) and urine β2-MG (μg g–1 Cr). The linear relationship was analyzed by Pearson correlation analysis.
