Other DEPs of interest included G2/M checkpoint related protein Cell division cycle 5-like protein (CDC5L), a putative target for checkpoint inhibition [17], and putative prognostic biomarkers in colorectal, breast and ovarian cancers: Metalloproteinase inhibitor 1 (TIMP1), Matrix metalloproteinase-9 (MMP9) [18] and Lysosome-associated membrane glycoprotein 1 (LAMP1) [19]. The gene discussed is MMP9; the disease is ovarian cancer.
