Wnt signaling pathwhay in cervical cancer. Expression levels of some genes participating in the wnt/β-catenin signaling pathway are altered in CC. Interestingly, Planar Cell Polarity pathway (PCP) is present in normal epithelial cells but is down-regulated in CC. A possible mechanism to accomplish PCP down-regulation is the inactivation of sFRP transcription. Yellow boxes indicate a down-regulation of expression in tumor cervices' samples compared to normal cervices' samples. Red boxes indicate a higher gene expression in cervical carcinoma samples. Blue boxes show that a member of the indicated gene family is expressed in normal tissues, and another member of the same family in tumors. Green boxes indicate that the gene was not altered.
