Glycolytic pathway analysis and gene expression profiles of combination of aloe vera and paclitaxel on non-small cell lung cancer and breast cancer

Abstract

The purpose of this study is to enhance the effectiveness of known anticancer medications using natural compounds. The study investigated the impact of combining AVE with PAX on non-small cell lung cancer (A549) and breast cancer (MCF7). In this study, A549 and MCF7 cells were treated with PAX (5 mu M), AVE (24 mu g/mL), and a combination of PAX and AVE (5 mu M + 24 mu g/mL). The glucose consumption rates of the cells were determined by extracellular acidification rate (ECAR) thanks to the SeaHorse XFe24 instrument. In addition, gene expression profiles were determined by performing Total RNA sequencing with the Novaseq 6000 instrument. Finally, the expressions of GAPDH, BAX, and BCL-2 genes involved in the apoptotic pathway were detected by RT-qPCR. The combined application of PAX and AVE reduced the ECAR value in both cell lines. According to the RT-qPCR results, the expression level of the apoptotic gene BAX increased in both cell lines (p < 0.05). Total RNA sequencing revealed that the combination effects of PAX and AVE play a role in the ribosome mechanism, thereby affecting the protein translation system in MCF7 while apoptosis and cell cycle have come to the forefront in A549.
