Tetrodotoxin (TTX) is a natural neurotoxin found in several species of puffer fish belonging to Tetraodon fugu genus and has been reported to affect processes such as proliferation, metastasis and invasion of various cancer cells. However, it was not revealed which genes were influenced by these reactions. In this experiment, it was examined in human SW620 colorectal cancer cells. The proliferation of SW620 cells was significantly reduced when treated with 0, 1, 10 and 100 μM TTX for 48 h. It was confirmed using Annexin V-propidium iodide staining that some apoptosis was induced. Differentially expressed genes (DEGs) affecting cell proliferation through RNA sequencing (RNA-seq) were selected. The expression change of DEGs was confirmed by conducting quantitative real-time polymerase chain reaction (qRT-PCR). As a result, the mRNA expression of FOS and WDR48 genes was found to be increased in the 100 μM TTX treatment group compared to the control group. On the other hand, the mRNA expression of ALKBH7, NDUFA13, RIPPLY3 and SELENOM genes was found to be reduced, and in the case of the ALKBH7 gene was identified to show significant differences. This experiment suggests that TTX can be used as an important fundamental data to elucidate the mechanism that inhibits the proliferation of SW620 cells.
