Transcriptional silencing of SLC5A8 gene in breast cancer / 国际外科学杂志

ABSTRACT

Objective To explore the phenomenon of gene silence of SLC5A8 in breast cancer.Methods Thirty-two patients suffered with breast cancer,hospitalized from June 2014 to June 2015 in affiliated hospital of Hebei university,were collected with the cancer tissue and normal specimen.Real-time quantitative PCR method was used to detect SLC5A8 gene transcription.Paired t-test and-test were used to anaylsed the results.Results Twenty cases of breast cancer tissues (62.5％) have no SLC5A8 gene transcription product,normal breast tissue adjacent to carcinoma specimens that had no product gene transcription was only five (12.5％).SLC5A8 inactivation rate of cancer tissue was significantly higher than normal tissue adjacent to carcinoma (P ＜ 0.05).The SLC5A8 mRNA transcription level of cancer tissue was significantly lower than the normal (P ＜ 0.05).Conclusion SLC5A8 gene transcription silence is the important events in the process of breast cancer occurrence and development.
