CPEB4 and neoplasm: Studies have shown that CPEB protein is abnormally expressed in various tumour cells and tissues, partially overlaps and affects cancer cells with other genes or pathways (e.g., p53, tPA, Bcl-xL/Bax, MAPK/ERK pathway, etc.), affects the proliferation, migration, and invasive ability of cancer cells, and participates in the regulation of the tumour epithelial–mesenchymal transition (EMT) process, and many studies have suggested that CPEB4 may be closely related to tumorigenesis and development [36].
