Some examples are corticosteroid and thyroxine binding globulins, which function as hormone transport proteins [4], the chaperone heat shock protein 47 [5], mammary serine protease inhibitor (Maspin), which increases the sensitivity of cancer cells to undergo apoptosis [6], and pigment epithelium derived factor (PEDF), which has neurotrophic, neuroprotective, antiangiogenic, and proapoptotic actions [7]. Here, SERPINF1 is linked to cancer.
