Proteomics analyses in both FST344‐ and FST317‐overexpressing ML‐2 cells showed consistent increases in protein expression of Cathepsin G (CTSG), TATA‐box binding protein‐associated factor 15 (TAF15), CD44, RNA binding motif protein 39 (RBM39), hematological and neurological expressed 1 (HN1), and Poly(C)‐binding protein 2 (PCBP2) (Appendix Fig S6A and B; Table EV3) of which TAF15 (Ballarino et al, 2013), CD44 (Quere et al, 2011), HN1 (Zhang et al, 2017), and PCBP2 (Han et al, 2013) have been associated with cancer initiation and progression. This evidence concerns the gene PCBP2 and cancer.
