Expression of interleukin-8 in interstitial fibroblast cells of breast cancer before and after application of docetaxel chemotherapy / 中国现代普通外科进展

ABSTRACT

Objective:To study and investigate the expression effects of interleukin-8 (IL-8)in interstitial fibroblast cells of breast cancer before and after the application of docetaxel chemotherapy.Methods:46 cases of breast cancer without chemotherapy surgical resection in patients with resected tissue specimens from August 2014 to February 2016 in our hospital were selected,all specimens were cultured to form stable breast cancer stromal fibroblast cells,each cell line after raising Daipei were divided into the observation group and control group,the control group cells without any treatment,the observation group of 24h cells treated with docetaxel(20ng/mL),two groups of cells were extracted from the mRNA and analyzed the gene expression and differential gene expression analysis,and then to PCR and protein to detected the expression level of electrophoresis detection of interleukin two interleukin-8 cells,the expression of interleukin-8 in two groups of breast cancer cells was observed and compared.Results:After docetaxel chemotherapy,the breast cancer stromal fibroblast gene expression changed,and compared to the control group,the observation group were given docetaxel chemotherapy after breast cancer between matter into fiber cell interleukin-6 serum IL-8 mRNA and protein expression levels were significantly higher than that of the control group,the difference had statistical significance (P＜0.05).Conclusions:Interleukin IL-8 in the breast cancer matter into fiber cells were significantly up-regulated after docetaxel chemotherapy,indicating that the expression changes of breast cancer may be related with the effect of chemotherapy and chemotherapy drug resistance related.
