Aim. To study the expression level of the genes DROSHA and DICER in peripheral blood leukocytes (PBL) of patients with sarcoidosis of the lungs Materials and methods. The study included 32 patients diagnosed with persistent lung sarcoidosis (mean age 41.56±1.27 years) and 36 healthy donors (control; mean age 42.79±1.95 years). The level of expression of messenger RNA (mRNA) of the genes DROSHA and DICER were determined in PBL of healthy donors and patients with sarcoidosis of the lung by polymerase chain reaction in real time. Results. As a result of the conducted researches it is established that the level of drosha gene expression in PBL patients with sarcoidosis of lungs is significantly reduced in comparison with the control (p

Abstract Background: PAHs exposure had been reported to be a risk factor of mtDNAcn in our early study. However, the effect of metabolic enzymes’ genetic polymorphisms on mtDNAcn in PAHs-Exposure workers has not been fully evaluated.Methods: We investigated the effects of metabolic enzymes’ genetic polymorphisms on mtDNAcn among 544 coke oven workers and 238 office staffs. The mtDNAcn of peripheral blood leukocytes was measured using Real-time quantitative polymerase chain reaction method. Polymerase chain reaction and restriction fragment length was used to detect five polymorphisms in GSTT1, GSTM1, GSTP1 rs1695, CYP2E1 rs6413432, and CYP2E1 rs3813867.Results: The mtDNAcn in peripheral blood leukocytes was significantly lower in the exposure group than that in the control group (P < 0.001). The 1-OHPYR had an increasing trend with the genotypes AA→AG→GG of GSTP1 rs1695 in the control group. Generalized linear model indicated that the influencing factors of mtDNAcn were PAHs-exposure [b(95% CI) = -0.420 (-0.469, -0.372), P < 0.001], male [β(95% CI) = -0.058 (-0.103, -0.012), P = 0.013] ,and AA genotype for GSTP1 rs1695 [β(95% CI) = -0.051 (-0.095, -0.008), P = 0.020].Conclusions: The male was susceptibility to PAHs exposure. The AA genotype of GSTP1 rs1695 may influence the toxicity of PAHs and associated with the decreased of mtDNAcn.
