Project description:To further explore the effect of blood lead on miRNA expression in blood, children (aged 2-5 years) from kindergartens of Shaanxi province were divided into two groups and blood samples were collected. miRNA array was used to testify miRNA expression landscape between low blood lead level (BLL) group (0~ 50.00 g/L) and high BLL group (>50.00 g/L).Our data showed that 27 miRNAs were highly differentially expressed. Expression of miR-34b from this signiture was quantified by qRT-PCR,linear regression analysis showed that the correlation coefficient between blood lead level and miR-34b is 0.247, p <0.001, indicating that miR-34b was correlated with BLL.
