Characteristics of the subjects and the curriculum laboris were determined by questionnaires. We measured the concentrations of metals in blood and urine samples using ICP-MS. The three circulating miRNAs studied were measured by quantitative PCR. Associations between miRNAs and internal exposure markers were assessed by simple and multiple regression analyses. miR-21 was significantly lower among welders (p = 0.017), compared with controls, adjusted for age, body mass index, smoking status and seniority. Significant adjusted associations were observed between miR-21 or miR-155 and urinary chromium (p = 0.005 or p = 0.041, respectively), miR-146a and urinary nickel (p = 0.019). The results of the multivariate analysis showed that duration of employment was the main factor responsible for the variation of miRNAs among welders. In conclusion, a recent exposure to certain metals, mainly chromium and nickel, appears to be associated to a decrease in plasma expression of miR-21, miR-146a and miR-155. Further larger studies would help to determine the mechanisms of action of metal particles on miRNA expression.Lire moins >
