title: SASH1 inhibits cervical cancer cell proliferation and invasion by suppressing the FAK pathway.
abstract: SAM and SH3 domain containing 1 (SASH1), a member of the SLY-family of signal adapter proteins, is a candidate tumor suppressor in several types of cancer. However, the role of SASH1 in cervical cancer remains to be elucidated. Therefore, in the present study, the role of SASH1 in cervical cancer and the underlying mechanism was investigated. Cell proliferation was detected by the MTT assay. Cell invasion was measured by Transwell assay. The mRNA expression levels of SASH1, matrix metalloproteinase (MMP)‑2 and MMP‑9 were determined by reverse transcription quantitative polymerase chain reaction. The protein expression levels of SASH1, MMP‑2, MMP‑9 and focal adhesion kinase (FAK) were determined by western blot analysis. The results demonstrated that SASH1 was downregulated in cervical cancer tissues and cell lines. Subsequently, a vector that overexpresses SASH1 was constructed. Overexpression of SASH1 was found to significantly inhibit cervical cancer cell proliferation and invasion, and also significantly reduce the expression of MMP‑2 and MMP‑9 in cancer cells. In addition, SASH1 modulated the FAK signaling pathway. Overexpression of SASH1 suppressed the expression of FAK in cancer cells. Taken together, the results suggested that SASH1 inhibits cervical cancer cell proliferation and invasion by suppressing the FAK pathway.
