Aim: 5-fluorouracil has been widely used in breast cancer treatment. Low level laser therapy (LLLT) has been shown to modulate biological processes and used in cancer treatment. It has been reported that apoptosis is induced by stimulation of transient receptor potential protein channels in numerous cancer cells, including breast cancer. We aimed to reveal the effects of 5-fluorouracil / Leucovorin (5-FU/LV) and low level laser on apoptosis via transient receptor protein ancyrin 1 (TRPA1) channels. Material and Methods: Breast cancer cells (MCF-7) were cultured and cells were divided into seven main groups. Cells were incubated with 5-FU/LV and LLLT exposure separately and together performed on MCF-7 cell cultures. Cell cultures incubated with TRPV1 channel antagonist capsazepin and stimulator capsaicin. The effects of 5-FU and LLLT were investigated on all molecular pathways of apoptosis. Results: It was found that the levels of apoptosis in 5-FU/LV group were significantly increased in cancer cells compared to control group. TRPA1 channel stimulator administration resulted in significantly increased apoptosis levels compared to the control group, in 5-FU/LV + low level laser group the apoptosis level significantly reduced compared to 5-FU/LV-only group. (p<0.001) Conclusion: It has been shown that 5-FU/LV significantly increases apoptosis in breast cancer cells, however low level laser administration decreases apoptosis and suppressed apopitotic effect of 5-FU/LV significantly on breast cancer cells.
