In conclusion, the circ0001658/circ0004928/circ0000376-miR-375-PAX6 axis may represent a new regulatory network that should be further investigated, and the results of this study provide a better understanding of GC.
Several studies have shown that microRNA-375 (miR-375) is frequently downregulated in several types of human cancer including gastric cancer, colorectal cancer and oral squamous cell carcinoma.
TCGA cohort was also used to analyze the expression correlation of YAP1, TEAD4, CTGF, and miR-375 in primary GCs. miR-375 was down-regulated in GC due to promoter methylation and histone deacetylation. miR-375 downregulation was associated with unfavorable outcome and lymph node metastasis.
Deregulation of MicroRNA-375 Inhibits Proliferation and Migration in Gastric Cancer in Association With Autophagy-Mediated AKT/mTOR Signaling Pathways.
Our study revealed miRNA profile in GC tissues and showed that miR-148a-3p, miR-223-3p and miR-375 are deregulated in GC plasma samples, but these circulating miRNAs showed relatively weak diagnostic performance as sole biomarkers.
