Effect and interaction of PINK1 genetic polymorphisms and environmental factors on blood pressure in COEs-exposed workers.

Coke oven emissions (COEs) contain a variety of polycyclic aromatic hydrocarbons (PAHs), which can cause damage to the human cardiovascular system. In addition, myocardial mitochondria are susceptible to damage in hypertensive patients. However, it is not clear whether genetic variation, in single nucleotide polymorphisms (SNPs) in PINK1 affects COEs exposure-induced abnormal blood pressure. We surveyed and tested 518 workers exposed to COEs and statistically analyzed them with SPSS 21.0 software. SBP was greater in the high-exposure group than in the low-exposure group. Generalized linear model analysis showed that the interaction of PINK1 rs3738136 (GA+AA) and COEs had an effect on SBP [β(95%CI) = -6.537(-12.072, -1.002), p  = 0.021] and DBP [β(95%CI) = -4.811(-8.567, -1.056), p  = 0.012]. This study is the first to identify the role of PINK1 rs3738136 in COE- induced abnormal blood pressure, and to prove that the abnormal blood pressure of workers is the result of environmental and genetic factors.
