These findings demonstrated that COL1A1-014 play an important regulatory role in GC development by functioning as a ceRNA in regulating the CXCL12/CXCR4 axis via sponging miR-1273h-5p.
The expression of CXCL12 in lymph node and liver metastasis was higher than that in primary gastric cancer tissues (<i>χ</i><sup>2</sup> = 6.669, <i>P</i> = 0.010; <i>χ</i><sup>2</sup> = 25379, <i>P</i> = 0.000), and the expression of CXCL12 in lymph node and liver metastasis of gastric cancer was consistent with the positive expression of CXCR7 in primary gastric cancer (<i>r</i> = 0.338, <i>P</i> = 0.000; <i>r</i> = 0.629, <i>P</i> = 0.000).
We also cover the current molecular mechanism, specifically the cell-signaling pathway, by which gastric cancer progresses through the CXCR4/CXCL12 axis, and discuss the potential of that axis as a therapeutic target in the treatment of gastric cancer.
In this study, we examined CXCL12 expression in gastric cancer and also evaluated whether the down-regulation of CXCL12 is due to aberrant methylation of the gene.
The results reveal a significant overexpression of phosphoglycerate kinase 1 (PGK1), the chemokine CXCR4 and its ligand CXCL12 in specimens from diffuse gastric cancer patients with peritoneal carcinomatosis.
