SFPQ and neoplasm: In our previous studies, we have successfully demonstrated that MALAT1 could promote tumor growth and metastasis in CRC by binding to SFPQ (PTB-associated splicing factor) and releasing oncogene PTBP-2 (polypyrimidine tract binding protein) from the SFPQ/PTBP-2 complex [5], and increase the nuclear translocation of β-catenin from cytoplasm, thereby activating downstream genes of β-catenin signaling pathway [6, 7].
