Methods: A total of 91 patients with breast cancer and 85 patients with breast adenoma who accepted surgical treatment in our hospital between August 2016 and February 2018 were selected, and the breast cancer tissues and breast adenoma tissues were collected respectively as the research samples. Fluorescence quantitative PCR method was used to detect the expression of Kif2a and HPK1 genes as well as oncogenes and drug resistance genes in sample tissues, and Pearson test was used to evaluate the inner link of Kif2a and HPK1 gene expression in breast cancer tissue with oncogene and drug resistance gene expression. Results: Kif2a mRNA expression in breast cancer tissues was higher than that in breast adenoma tissues whereas HPK1 mRNA expression was lower than that in breast adenoma tissues;oncogenes DEK, iASPP-SV, Stat3, MDM2 and Fra-1 mRNA expression were higher than those in breast adenoma tissues;drug resistance genes ESR1, MDR1, P-gp, MRP1 and GST- mRNA expression were higher than those in breast adenoma tissues whereas BCRP mRNA expression was lower than that in breast adenoma tissues. Correlation analysis showed that the Kif2a and HPK1 gene expression in breast cancer tissues were directly correlated with the expression of oncogenes and drug resistance genes. Conclusion: Kif2a gene is abnormally highly expressed whereas HPK1 gene is abnormally lowly expressed in breast cancer tissues, and they are involved in the regulation of oncogene and drug resistance gene expression.展开更多
