Abstract

Objectives: This study aims to investigate the expressions of MAP2K3, MAP3K7, and MAPK8 genes after disodium pentaborate decahydrate (DPD)treatment in DU-145 cells.

Materials and methods: Effect of DPD treatment on expressions of MAP2K3, MAP3K7, and MAPK8 genes were determined by qRT-PCR.

Results: We determined that disodium pentaborate decahydrate treatment increased the expressions of MAP2K3, MAP3K7, and MAPK8 genes in termsof mRNA levels.

Conclusion: The reason of increased apoptosis might be associated with high expression levels of MAP2K3, MAP3K7, and MAPK8 genes after DPDtreatment. Our novel findings suggest

Abstract

Amaç: Bu çalışmada DU-145 hücrelerinde disodyum pentaborat dekahidrat (DPD) uygulamasının ardından MAP2K3, MAP3K7 ve MAPK8 genlerinin ekspresyonları araştırıldı.Gereç ve yöntemler: Disodyum pentaborat dekahidrat uygulamasının MAP2K3, MAP3K7 ve MAPK8 genlerinin ekspresyonlarına olan etkisi qRT-PCR ile belirlendi.Bulgular: Disodyum pentaborat dekahidrat uygulamasının MAP2K3, MAP3K7 ve MAPK8 genlerinin mRNA seviyelerini artırdığı belirlendi.Sonuç: Apoptoz artışının, MAP2K3, MAP3K7 ve MAPK8 genlerinin DPD uygulaması sonrasında yükselen ekspresyon seviyelerine bağlı olarak gerçekleştiği düşünülmektedir. Güncel bulgularımız DPD’nin prostat kanseri tedavisinde mitojenik ve çevresel strese karşı apoptoza neden olan önemli bir etken olabileceğini öngörmektedir
