Abstract
- Circular RNAs are emerging players in human cancers, including esophageal squamous cell carcinoma (ESCC). Herein, we assessed the expression level of circ_0023990 and explored the molecular mechanisms of circ_0023990 in ESCC. circ_0023990, miR-6884-5p, and PAK1 expressions in ESCC tissues and cells were detected by quantitative real-time polymerase chain reaction and western blot. ESCC cells were transfected with different constructs to alter the expression of circ_0023990, miR-6884-5p, and PAK1. The effect of circ_0023990 on the proliferation, invasion, and glycolysis of ESCC cells was observed. The interaction between circ_0023990 and miR-6884-5p and between miR-6884-5p and PAK1 were explored. A mouse model of ESCC was established to study the in vivo effect of circ_0023990 knockdown on tumor formation.The expression levels of circ_0023990 was upregulated in ESCC tissues and cells. Inhibiting circ_0023990 suppressed the proliferation, invasion, and glycolysis of ESCC cells. circ_0023990 might target miR-6884-5p and consequently modulate the expression and activity of PAK1. Knockdown of circ_0023990 led to significantly reduced tumor volume and weight in mice with ESCC.These findings overall suggest an oncogenic role of circ_0023990 in ESCC. Future research is warranted to confirm the expression pattern and clinical significance of circ_0023990 in ESCC. [ABSTRACT FROM AUTHOR]
