STRIP2 Stabilizes LCN2 to Suppress Ferroptosis and Drives Colorectal Cancer Malignancy
Listed in NCBI GEO
Colorectal cancer (CRC) poses a severe global health threat with high incidence, mortality, and poor 5-year survival rates for advanced cases despite existing treatments.
Description
This study aims to explore the role of STRIP2 in CRC progression and its underlying mechanisms. Impact of STRIP2 on CRC in vitro was investigated via CRC cell proliferation, migration, invasion, and apoptosis.
The in vivo impact was investigated via nude mice models. The role of STRIP2 in CRC was investigated via transcriptomic analysis, Western blot, Co-immunoprecipitation assays and ferroptosis validations. STRIP2 is overexpressed in CRC, driving malignant phenotypes in vitro and in vivo.

Mechanically, STRIP2 stabilizes the IL17 downstream effector LCN2 by blocking its K48-linked ubiquitination and degradation, enhances anti-ferroptosis of CRC cells. Oe-STRIP2 suppresses ferroptosis, boosting proliferation and reducing oxidative stress; while si-STRIP2 induces the opposite effect. This study suggests STRIP2-mediated stabilization of LCN2 and enhances CRC cells ferroptosis resistance, thus promoting CRC cell survival and mediates malignant progression in CRC, which provides a novel link between STRIP2 and ferroptosis regulation in CRC.
