We also discovered that oncogene phosphatidylinositol-3, 4, 5-trisphosphate-dependent Rac exchange factor 2 (PREX2) was a downstream target of miR-340, and PREX2 expression was positively correlated to that of MYCNOS in HCC tissues.
Involvement of TLR4/ CXCL9/ PREX-2 pathway in the development of hepatocellular carcinoma (HCC) and the promising role of early administration of lactobacillus plantarum in Wistar rats.
The overexpression of Phosphatidylinositol-3,4,5-Trisphosphate Dependent Rac Exchange Factor 2 (PREX2) is observed in various tumors, including HCC; and the frequent PREX2 mutations in melanoma are associated with invasiveness.
PREX2 protein expression was upregulated in 54.9% of human HCC samples, while its mRNA level was comparable in tumor and tumor-adjacent tissue, suggesting a post-translational alteration of PREX2 expression.
