Colorectal cancer (CRC) remains one of the most common cancers worldwide.
Increasing evidence indicates that SPRY4 intronic transcript 1 (SPRY4-IT1)
regulate cell growth, differentiation, apoptosis, and cancer progression.
However, the expression and function of SPRY4-IT1 in the progression of CRC
remains largely unknown. Here, we reported that SPRY4-IT1 was upregulated in CRC.
Increased SPRY4-IT1 expression in CRC was associated with larger tumor size and
higher clinical stage. In vitro experiments revealed that SPRY4-IT1 knockdown
significantly inhibited CRC cell proliferation by causing G1 arrest and promoting
apoptosis, whereas SPRY4-IT1 overexpression promoted cell proliferation. Further
functional assays indicated that SPRY4-IT1 overexpression significantly promoted
cell migration and invasion by regulate the epithelial-mesenchymal transition
(EMT). Taken together, our study demonstrates that SPRY4-IT1 could act as a
functional oncogene in CRC, as well as a potential therapeutic target to inhibit
CRC metastasis.
