چکیده

Background: arecoline,a major alkaloid in areca nut has the ability to induce oxidative stress. the effect of areca nut,arecoline on reducing sperm quality and quantity were documented previously using several animal models. junction disruption by down-regulation of the junction-adhesive protein via oxidative stress is an important route mediating abnormal spermatogenesis. therefore,in this present study,we investigated the functional role of arecoline on junctional proteins. results: to analyze direct effects of arecoline on testis cells,confluent mouse testicular sertoli cell line tm4 was exposed to arecoline. arecoline decreased insoluble zonula occludens-1 (zo-1) protein expression in tm4 cells,however,arecoline treatment increased tnf-alpha production in both tm4 and monocytic thp1 cells. in addition,erk1/2 inhibitor pd98059 reversed arecoline effects on tnf-alpha and zo-1. conclusions: arecoline increases the production of tnf-alpha and induces protein redistribution of zo-1. all these results explain the role of arecoline in male reproductive dysfunction,besides its cytotoxic induction. © 2014 kuo et al.; licensee biomed central ltd.
