Transcriptome analysis for CT mRNA treated BT-549 cells and negative control cells

We report the altered metabolite changes by processing CT mRNA in the TNBC cell line, BT-549. It was confirmed that the treatment of CT mRNA disrupted the synthesis of dTTP during nucleic acid metabolism, increasing the signal related to DNA damage in the cell, and that the energy metabolism and NADPH metabolism in the cell were changed for its recovery. The main energy sources, glucose metabolism and glutamine metabolism, are closely linked to the mitochondrial TCA cycle products. In the CT mRNA treatment group, intracellular nucleic acid depletion was observed to increase glutamine metabolism as a source of N source, and the pathway of aspartate utilization was observed. It was confirmed that it was expanded. As a result, a significant increase in the cysteine influx was observed according to the occurrence of ROS, and an effort to regulate the intracellular NADPH balance was observed through the change of metabolites over time. Finally, it was observed that the oncogenic pathway was significantly reduced in the CT mRNA-treated group compared with all untreated groups or controls with other substrate specificities. This study characterizes changes in intracellular metabolites caused by specific dTTP biosynthesis disturbances. Overall design: Examination of T001 mRNA, 2 different nucleotidase and untreated cells
