Objective: To explore the relationship and mechanism of LZAP in the occurrence and development of cervical cancer and to provide a new target and intervention method for the treatment of cervical cancer.

Methods: Data mining and analysis of LZAP expression levels were performed using several online databases, including The Cancer Genome Atlas (TCGA). A cervical cancer cell line that stably overexpresses LZAP was established, and the effect of LZAP overexpression on cell proliferation, invasion, migration and tumor formation in vivo as well as its mechanism were explored.

Results: Our study shows that the expression of LZAP is upregulated in cervical cancer. The overexpression of LZAP can significantly promote the proliferation, colony formation, and invasion and migration abilities of cervical cancer cells. The tumorigenesis test in nude mice showed that overexpression of LZAP could promote the tumorigenicity of cervical cancer cells in vivo. LZAP could also promote the phosphorylation of AKT at position 473 and the epithelial-mesenchymal transition (EMT).

Conclusion: The expression of LAZP is increased in cervical cancer, which can enhance the invasion, metastasis, and EMT in cervical cancer cells by promoting AKT phosphorylation.

Keywords: LZAP, EMT, Cervical Carcinoma, Metastasis
