The H1975 cell line (56) has the highest relative level of EMT and also has higher levels of and in our study. We identified 376 DEGs, consisting of 83 upregulated genes and 293 downregulated genes. Functional and pathway enrichment showed that the DEGs were mainly focused on regulation of cell proliferation, the transforming growth factor receptor signaling pathway, cell adhesion, biological adhesion, and responses to hormone stimulus. Sixteen hub genes were identified and biological process analysis showed that these 16 hub genes were mainly involved in the M phase, cell cycle phases, the mitotic cell cycle, and nuclear division. We further confirmed the two genes with the highest node degree, DNA topoisomerase II ((forward, 5-AGGATTCCGCAGTTACGTGG-3 and reverse, 5-CATGTCTGCCGCCCTTAGAA-3) (20) and (forward, 5-TTGGGTGGTCAGTACATGCTC-3 and reverse, 5-GTGAATTCAACCCGTGAT-3) Rabbit polyclonal to Claspin (21) and sense, 5-CAATGACCCCTTCATTGACC-3 and reverse, 5-TGGAAGATGGTGATGGGATT-3. The statistical analyses were conducted using SPSS version 21 (IBM Corp.). Results are displayed as mean SEM and differences between the HBE and cancerous cell lines were analyzed by one-way ANOVA. We further used the Tukey test to determine the significance between each malignancy cell collection and HBE. P-value 0.05 was considered to indicate statistical significance. Each experiment was repeated three times.
