In addition, a correlation analysis from our immunochemical staining data from cervical cancer tissues as well as cervical cancer cDNA microarray datasets (GSE5787) indicated that LGR5 expression is positively correlated with the expression of target genes of the Wnt/β-catenin pathway in human cervical cancer tissues (Fig. 6), which indirectly supports our proposal that LGR5 may potentiate the Wnt/β-catenin pathway in cervical cancers. Here, LGR5 is linked to cervical carcinoma.
