Hypothesis and Objective: Genes participating in the notch signaling pathway are influenced by exposure to high nitrous oxide (HNO) levels. Notch signaling pathway genes are responsible for regulating cell fate, differentiation, and apoptosis. Dysregulation of these genes can contribute to tumorigenesis. Alterations in the expression of these genes in MCF7 breast cancer cells could help determine the effects of the notch signaling pathway on tumorigenesis as a result of exposure to nitrous oxide.
Methods: Samples of cDNA from MCF7 and MCF7-HNO cells were used in DNA microarray analysis. Qualifying genes of interest provided a p value < .05. Differentially expressed genes (DEGs) were defined and categorized using the Gene Oncology Uniprot (GO) Molecular Function database. These cells were further analyzed using a proprietary bioinformatics analysis created by our laboratory.
Results: Exposure to HNO …
