Abstract: Aim: Cervical cancer is the deadliest gynecological malignancy. This study aims to examine the anticancer effects of L-citrulline on HeLa cell culture. Materials and Methods: HeLa cells were cultured in complete Eagle's minimum essential medium. HeLa cells were seeded in 96-well plates and incubated with L-citrulline. After incubation, MTT dye was added and incubated. Annexin-V technique was used to test the apoptosis. The activated caspases of HeLa cells by L-citrulline exposure were measured with the Caspase 3/7 technique. One-way variance analysis was conducted for statistical analysis by using GraphPad Prism 6.0 for Windows. Results: L-citrulline showed its toxicity on HeLa cells in a dose-dependent manner in application times of 24 and 48 hours. The IC50 dose of L-citrulline was 0.19 and 0.16 mg/mL at 24 and 48 hours, respectively. When HeLa cells were exposed to an IC50 dose of L-citrulline for 24 hours, the percentages of the dead, early apoptotic, and late apoptotic cells were detected to be 0.75%, 23.05%, and 12.75%, respectively. The differences in the wideness of the scratch area were observed at the initial stage and after 24 hours of applying L-citrulline. Conclusion: L-citrulline showed its toxicity on HeLa cells in a dose-dependent manner. Based on Annexin and Caspase findings, it can be concluded that L-citrulline exerted a pro-apoptotic effect on HeLa cells in only a short exposure time. L-citrulline also showed a migration inhibitory effect. The findings of this study indicate L-citrulline to be worthy of investigation for its anticancer activities in vitro and in vivo, and as a candidate for cancer therapy.
