title: Leucine zipper tumor suppressor 2 inhibits cell proliferation and regulates Lef/Tcf-dependent transcription through Akt/GSK3β signaling pathway in lung cancer.
abstract: Leucine zipper tumor suppressor 2 (LZTS2) is implicated in several cancers; however, its biological mechanisms in non-small cell lung cancer (NSCLC) are not yet understood. We found that low levels of LZTS2 in NSCLC were correlated with tumor and nodal status. LZTS2 could inhibit cell proliferation and cell cycle transition at the G1/S phase and was implicated in the regulation of proteins associated with the canonical Wnt pathway, including GSK3β and β-catenin through inactivating the Akt pathway. These results provide novel mechanistic insight into the biological roles of LZTS2 in lung cancer cells.
