Bisphenol A, S, and F exposure, ESR1/2, CAT, and eNOS genetic polymorphisms, and the risk of hypertension

Abstract

While bisphenol A (BPA) exposure was inconsistently associated with hypertension risk, little is known about whether its alternatives bisphenol S and F (BPS and BPF) have similar hypertensive effects. Furthermore, epidemiologic studies on the genetic susceptibility to the hypertensive effects of bisphenols are scarce. We conducted a case-control study in 439 pairs of hypertension cases and matched controls. Urinary bisphenols concentrations were measured to characterize the internal exposure levels. The genotyping of ESR1/2, CAT, and eNOS was performed by a multiplex fluorescent polymerase chain reaction. BPA exposure was positively associated with hypertension risk. Carriers of rs2234693 C allele in ESR1 were associated with increased hypertension risk. Significant associations of BPA exposure with increased hypertension risk were suggested in individuals with the major allele of rs1256049 in ESR2, rs769214 in CAT, and rs1799983 in eNOS. Besides, rs4755374 in CAT might modify the association of BPA exposure with hypertension risk. Individuals with specific genotypes in ESR1/2, CAT, and eNOS might be more susceptible to the hypertensive effects of BPA.
