More Details: Telomeres are functional complexes at the ends of linear chromosomes, and telomerase aids in their maintenance and replication. Additionally, accumulating evidence suggests that telomerase-associated protein 1 (TEP1) is a component of the telomerase ribonucleoprotein complex and is responsible for catalyzing the addition of new synthetic telomere sequences to chromosome ends. In our previous study, we found that genetic variants of the TERT gene participated in the regulation of telomere length. Exposure to particulate matter, environmental pollutants, oxidative stress, and pesticides is associated with shortening of telomere length. However, it is unknown whether genetic variants in the TEP1 gene may affect telomere length (TL) in polycyclic aromatic hydrocarbon (PAH)-exposed workers. Therefore, we measured the peripheral leukocyte TL and genotyped the polymorphism loci in the TEP1 gene among 544 PAH-exposed workers and 238 healthy controls. Covariance analysis showed that the individuals carrying TEP1 rs1760903 CC and TEP1 rs1760904 TT had longer TL in the control group (P
