Circ_0008035 contributes to cell proliferation and inhibits apoptosis and ferroptosis in gastric cancer via miR-599/EIF4A1 axis.

ABSTRACT:

Background

Currently, multiple circular RNAs (circRNAs) have been verified to act as essential regulators in the progression of gastric cancer (GC). We aimed to investigate the role of circ_0008035 in GC progression.

Methods

Quantitative real-time polymerase chain reaction (qRT-PCR) was utilized to measure the expression of circ_0008035 and miR-599. 3-(4,5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assay was employed to evaluate cell proliferation and ferroptosis. Western blot assay was performed to measure the levels of cyclin D1, proliferating cell nuclear antigen (PCNA) and eukaryotic initiation factor 4A1 (EIF4A1). Flow cytometry analysis was conducted to assess cell apoptosis. The iron accumulation, lipid peroxidation and mitochondrial memb
