High brain acid soluble protein 1(BASP1) is a poor prognostic factor for cervical cancer and promotes tumor growth

Abstract Background The aim of this study was to determine whether brain abundant membrane attached signal protein 1 (BASP1) is a valuable prognostic biomarker for cervical cancer and whether BASP1 regulates the progression of cervical cancer. Methods Quantitative real-time PCR, western blotting, and immunohistochemistry were used to determined BASP1 levels. Statistical analyses were used to examine whether BASP1 was a prognostic factor for patients with cervical cancer. The MTT assay, colony formation assay, cell cycle assay, anchorage-independent growth assay, and a tumor xenograft model were used to determine the role of BASP1 in the proliferation and tumorigenicity of cervical cancer. Results Brain abundant membrane attached signal protein 1 was upregulated in cervical cancer tissues and cells, and BASP1 expression levels were higher in patients that had died during follow-up compared with those that survived. There was a positive correlation between BASP1 expression and clinical stage (p
