ABSTRACT
Sulfur mustard (SM) exposure has delayed harmful effects, including premature biological aging. This study aimed to evaluate the expression of aging markers (i.e., ANRIL, P16INK4a, TBX2, and TERRA) and assess their correlation with the severity of SM exposure in the long term. The study was conducted on two volunteer groups. 1) SM-exposed group, exposed to SM once in 1987 during the war; divided into three subgroups based on the injury severity, asymptomatic (without any clinical signs), mild, and severe; 2) Non-exposed group. In the SM-exposed group, ANRIL transcript was decreased, especially in subgroups of mild and severe. TBX2 transcript was also decreased in the total SM-exposed group. This decrease was more significant in the mild and severe subgroups than in asymptomatic ones. P16INK4a transcript was increased in the SM-exposed group, especially in the asymptomatic subgroup. The increase in TERRA transcript was also significant in all subgroups. There was a positive correlation between the TERRA transcript and the severity of injury, while this correlation was negative for the ANRIL. It is concluded that the delayed toxicity of SM may be associated with dysregulation of aging markers leading to premature cellular aging. These markers' alterations differed according to the severity of SM injury.
