Abstract

Background: Lung adenocarcinoma (LUAD) is one of the respiratory diseases with high mortality and incidence. As an important angiogenic factor, (Endothelial cell-specific molecule 1) ESM1 plays an important role in the occurrence and development of LUAD. However, the role and molecular mechanism of ESM1 on LUAD metabolic reprogramming and angiogenesis remain unclear.

Methods: We used multiple databases to analyze the prognostic significance and potential function of ESM1 in patients with LUAD. The expression of ESM1 in LUAD cells was down-regulated/overexpressed by RNA interference, and the effects of ESM1 on the proliferation, migration, lipid metabolism and angiogenesis of LUAD cells in vitro and in vivo were analyzed using MTT, EdU, wound healing, oil red O, tubule formation, xenograft tumor model and chicken embryo allantoic model.

Results: ESM1 is closely associated with poor prognosis in LUAD patients. ESM1 promotes LUAD proliferation, migration, fatty acid synthesis and angiogenesis. It also accelerates the proliferation, migration, lipid synthesis and tubule formation of endothelial cells in the tumor microenvironment in the form of secreted protein. Mechanically, ESM1 can promote the activation of AKT signaling pathway and up-regulate the expression of SCD1 and FASN.

Conclusion: Our results suggest that ESM1 promotes the proliferation, migration, lipid reprogramming, and angiogenesis of LUAD cells by activating the AKT signaling pathway, suggesting that ESM1 may be a potential therapeutic target and prognostic marker in LUAD patients.
