GBP2 regulates lung cancer progression through STAT1 and impacts glycolysis.

ABSTRACT: Lung cancer remains one of the leading causes of cancer-related mortality worldwide, highlighting the need for novel biomarkers and therapeutic targets. In this study, we sought to assess the role of guanylate-binding protein 2 (GBP2) in lung cancer and its potential as a prognostic marker. Immunohistochemical analysis on tissue microarrays revealed significantly elevated GBP2 expression in lung cancer tissues compared to non-neoplastic adjacent tissues, correlating with advanced tumor stages, lymph node metastasis, and poor patient survival. In vitro experiments using GBP2 knockdown in NCI-H1299 and A549 lung cancer cell lines showed reduced cell proliferation, increased apoptosis, and inhibited cell migration, alongside cell cycle arrest at the G2 phase. In vivo studies confirmed that GB
