Tumor invasion and metastasis are closely associated with epithelial?mesenchymal
transition (EMT). EMT refers to epithelial cells under physiological and
pathological conditions that are specific to mesenchymal transition. Curcumin
inhibits EMT progression via Wnt signaling. The Wnt signaling pathway is a
conservative EMT?related signaling pathway that is involved in the development of
various tumors. In the present study, MTS assays were employed to analyze the
proliferation of curcumin?treated cells. Naked cuticle homolog 2 (NKD2),
chemokine receptor 4 (CXCR4) and antibodies associated with EMT were examined in
SW620 colorectal cancer cell lines using western blot analysis and real?time
qPCR. NKD2 small?interfering RNA (siRNA) and CXCR4 expression plasmid was
synthesized and transfected into the colorectal cancer cell lines, and NKD2 and
CXCR4 expression levels were detected. The results showed that curcumin
significantly inhibited the proliferation of colorectal cancer cells and
upregulated the expression of NKD2 in SW620 colorectal cancer cells and in the
xenograft, resulting in the downregulation of key markers in the Wnt signaling.
In addition, the progression of ETM was inhibited due to the overexpression of
E?cadherin as well as the downregulation of vimentin. Curcumin also inhibited
tumor metastasis by downregulating the expression of CXCR4 significantly. The
results suggested involvement of the NKD2?Wnt?CXCR4 signaling pathway in
colorectal cancer cells. In addition, curcumin is inhibit this signaling and the
development of colorectal cancer.
