RT Journal Article SR Electronic T1 No Association Between Serum Paraoxonase, Arylesterase Activities, and Hydatidiform Mole JF International Journal of Gynecologic Cancer JO Int J Gynecol Cancer FD BMJ Publishing Group Ltd SP 149 OP 152 DO 10.1097/IGC.0b013e3182021c59 VO 21 IS 1 A1 Ozturk, Ebru A1 Balat, Ozcan A1 Dikensoy, Ebru A1 Ugur, Mete Gurol A1 Ozcan, Caglayan A1 Aydin, Abdullah A1 Erel, Ozcan A1 Kul, Seval YR 2011 UL http://ijgc.bmj.com/content/21/1/149.abstract AB Background: In this study, we aimed to evaluate the association between hydatidiform mole (HM) and paraoxonase 1 (PON1) activity and phenotyping in comparison with healthy subjects (both pregnant and nonpregnant women).Methods: Eighty women were enrolled in this study. Of these, 26 had HM (group 1). Twenty-seven healthy women in the first trimester of pregnancy with a single viable fetus were included in the study as control subjects (group 2). The remaining 27 subjects were healthy nonpregnant women who also participated as control subjects (group 3). Paraoxonase and arylesterase activities were measured using commercially available kits (Relassay, Gaziantep, Turkey). Paraoxonase activity measurements were performed both in the absence (basal activity) and presence of NaCl (salt-stimulated activity). The phenotype distribution of PON1 activity was determined by the double-substrate method.Results: Basal and salt-stimulated paraoxonase and arylesterase activities were not significantly different between the HM, healthy pregnant control, and healthy nonpregnant control groups. Hence, PON1 phenotype distribution of the subjects was not significantly different between these 3 groups.Conclusions: We determined no association between HM (complete or partial) and PON1 activity and phenotyping in comparison with pregnant and nonpregnant healthy subjects. Further studies including metastatic or invasive HM are needed.
