Loss of large tumor suppressor kinase 1 (LATS1)Y has been implicated in numerous
types of human cancer. However, its involvement in human cervical cancer remains
to be elucidated. The present study aimed to investigate the clinical
significance and biological characteristics of LATS1 in human cervical cancer.
The present study investigated the protein expression levels of LATS1 in tissues
from 80 cases of cervical cancer using immunohistochemistry and demonstrated that
LATS1 was downregulated in 45% (36/80) of cervical cancers. Transfection of LATS1
was performed in the SiHa cell line and LATS1 siRNA knockdown was performed in
the Caski cell line. MTT assay and Matrigel invasion assay indicated that LATS1
overexpression inhibited cell proliferation and invasion. LATS1 overexpression
upregulated p27 expression, and downregulated the expression of cyclin E and
matrix metalloproteinase 9. In addition, LATS1 overexpression stimulated
yes?associated protein 1 (YAP) phosphorylation. Depletion of LATS1 in Caski cells
resulted in the opposite effects. The current study demonstrated that LATS1 was
downregulated in cervical cancer and may suppress cell growth and invasion
through regulating the expression of cyclin E, p27, MMP9 and YAP.
