Figure 7. Positive correlation between expression levels of DARPP-32, CXCL-12 and CXCR-4.
The qRT-PCR analysis of the expression levels of CXCL-12, CXCR4, and DARPP-32 in gastric tumors and their adjacent histologically normal non-tumor tissue samples demonstrated a statistically significant positive correlation between the levels of CXCL-12 and DARPP-32 (A) and between CXCR4 and DARPP-32 (B), suggesting that these components of invasion activity co-exist in gastric cancer cells.
