Platelet-activating factor acetylhydrolase 1B3 (PAFAH1B3), one of the catalytic subunits of PAFAH, plays an important role in apoptosis (Monillas et al., 2015), cancer metastasis (Stafforini, 2015), and angiogenesis during cancer (Sun et al., 2015). This evidence concerns the gene PAFAH1B1 and cancer.
