LATS2 inhibits cell proliferation and metastasis through the Hippo signaling pathway in glioma

Abstract

As a core kinase in the Hippo pathway, large tumor suppressor kinase 2 (LATS2) regulates cell proliferation, migration and invasion through numerous signaling pathways. However, its functions on cell proliferation, migration and invasion in glioma have yet to be elucidated. The present study revealed that LATS2 was downregulated in glioma tissues and cells, as determined by reverse transcription‑quantitative polymerase chain reaction and immunohistochemistry. In addition, Cell Counting Kit‑8, scratch wound healing and Transwell assays revealed that overexpression of LATS2 in U‑372 MG cells inhibited cell proliferation, migration and invasion. Furthermore, western blot analysis indicated that the expression levels of phosphorylated (p)‑yes‑associated protein and p‑tafazzin were increased in cells with LATS2 overexpression. These results indicated that LATS2 is a potential tumor suppressor, and downregulation of LATS2 in glioma may contribute to cancer progression.
