Objective: Bacterial toxin can cause cell death through induction of apoptosis in cancer cell lines as well as changes in the expression patterns of long non-coding RNAs (lncRNAs) and genes. In the present study, the effect of tst gene on ACHN cell lines was reported along with a novel pathways of apoptosis in kidney cancer.
Materials and Methods: In this experimental study, effective lncRNAs and genes were predicted from different criteria for Renal Cell Carcinoma (RCC) by bioinformatics methods and lncRNA-miRNA-mRNA interaction was constructed; then the effect of Staphylococcus aureus tst gene on induction of apoptosis pathways on ACHN and HDF cell lines was investigated.
Results: After creation of lncRNA-miRNA-mRNA interaction, changes in expression levels of LINC00847 lncRNA (p= 0.0024) and PTEN gene (p= 0.0027) were identified, as potential apoptosis biomarkers for kidney cancer, after treating ACHN cell line by pCDNA3.1 (+)-tst compared to empty vector. In contrast, there was no statistically significant difference in DICER1 expression levels in ACHN-tst cell (P≥0.05). Also, transfection by pcDNA3.1 (+)-tst could increase ACHN cell apoptosis level (P< 0.0001) compared to pcDNA3.1 (+) group; but no significant effect was observed on normal cells.
Conclusion: It is suggested that new lncRNA, LINC00847, discovered in this study could provide a new landscape for researches aimed at determining the relationship between functional lncRNA and RCC pathways. pcDNA3.1 (+)-tst was found to increase apoptosis in transfected cells.
