Comet assay results depicting the impact of Tilapia piscidin 4 (TP4) treatment on MCF-7 cells at concentrations of 25% and 50% for 24 h. The lower panel illustrates the quantification of DNA tail percentage in 100 cells. Mean ± standard deviation (SD). Different letters show significant difference between groups at p < 0.05 level. Asterisks (*) indicates significant difference between control and treatment groups at p < 0.01 level.
