To evaluate the toxicity effect of the pesticides including benomyl,carbaryl, malathion, diazinon on male Balb/c mice, expression profile of two oncogenic miRNAs were analysedby real-time PCR.Material and Method:The 72 male mice were divided into 6 groups (n = 6 per group), including control(0 mg/kg), malathion (30 mg/kg), carbaryl (20 mg/kg), benomyl (30 mg/kg), diazinon (20 mg/kg) and mixtureof all pesticides. Mice were intragastrically gavaged for 60 days, then sacrificed on the 30(th) and 60(th) day.The levels of oncogenic mir-17 and mir-221 in the serum were measured.Result and Discussion: The results showed that compared with the normal controls, mir-17 and mir221 were overexpressed in all treatment groups during 2 months. The expression level of miR-17 and mir-221after 60 days were 9.2-17.7 fold and 1.9-4 fold higher than the first month respectively. The lowest increasewas 1.9-fold, belongs to mir-221, which is still enough for easy diagnosis. These results provide new insightsinto the negative pesticide’s carcinogenic probability via dysregulation of two oncogenic miRNAs. Our resultssuggest that due to positive association between mir-17 and mir-221 levels and the risk of toxicity, these miRNAsmight be a useful biomarker in malignancy prediction and have a diagnostic value.

Pestisitlerin toksisite etkisini değerlendirmek üzere erkek Balb/cfarelerinde benomil, karbaril, malatiyon, diazinonun onkojenik miRNA ekspresyona etkisi gerçek zamanlı PCRile analiz edildi.Gereç ve Yöntem: 72 erkek fare 6 gruba ayrıldı: kontrol (0 mg/kg), malatiyon (30 mg/kg), karbaril (20mg/kg), benomil (30 mg/kg) ve diazinon (20 mg/kg). Fareler 60 gün boyunca intragastrik yoldan sonda ilebeslendi, daha sonra 30. ve 60. gününde öldürüldü. Serumda onkojenik mir-17 ve mir-221 düzeyleri ölçüldü.Sonuç ve Tartışma: Sonuçlar normal kontrollerle karşılaştırıldığında, mir-17 ve mir-221 tüm tedavigruplarında 2 ay boyunca aşırı eksprese edildiği görüldü. Mir-17 ve mir-221 ekspresyon düzeyi ilk aya göre 60gün sonra sırasıyla 9,2-17,7 kat ve 1,9-4 kat daha yüksekti. En düşük artış 1,9 kat ile mir-221'e aittir ki, halakolay teşhis için yeterlidir. Bu sonuçlar iki onkojenik miRNA’nın disregülasyonuyla pestisitlerin negatifkarsinojenik olasılığına yeni bilgiler sağlamaktadır. Sonuçlarımız mir-17 ve mir-221 seviyeleri ve toksisite riskiarasındaki pozitif ilişki nedeniyle, bu miRNA'ların malignite tahmininde yararlı bir biyobelirteç olabileceğinive diyagnostik değeri olduğunu göstermektedir.
