Fig. 1: Expression of CB1 and EGFR in normal colon cells and colorectal cancer cells.

A QPCR results showed that CB1 was downregulated in colorectal cancer cells. B QPCR results showed that EGFR was upregulated in colorectal cancer cells. C, D Western blot analysis showed that CB1 was downregulated and EGFR was upregulated in colorectal cancer cells. *P < 0.05; **P < 0.01.
