Sprouty (SPRY) appears to act as a tumor suppressor in cancer, whereas we
demonstrated that SPRY2 functions as a putative oncogene in colorectal cancer
(CRC) (Oncogene, 2010, 29: 5241-5253). We investigated the mechanisms by which
SPRY regulates epithelial-mesenchymal transition (EMT) in CRC. SPRY1 and SPRY2
mRNA transcripts were significantly upregulated in human CRC. Suppression of
SPRY2 repressed AKT2 and EMT-inducing transcription factors and significantly
increased E-cadherin expression. Concurrent downregulation of SPRY1 and SPRY2
also increased E-cadherin and suppressed mesenchymal markers in colon cancer
cells. An inverse expression pattern between AKT2 and E-cadherin was established
in a human CRC tissue microarray. SPRY2 negatively regulated miR-194-5p that
interacts with AKT2 3' untranslated region. Mir-194 mimics increased E-cadherin
expression and suppressed cancer cell migration and invasion. By confocal
microscopy, we demonstrated redistribution of E-cadherin to plasma membrane in
colon cancer cells transfected with miR-194. Spry1(-/-) and Spry2(-/-) double
mutant mouse embryonic fibroblasts exhibited decreased cell migration while
acquiring several epithelial markers. In CRC, SPRY drive EMT and may serve as a
biomarker of poor prognosis.
