Abstract: Zinc (Zn) is an essential micronutrient that is required in over 300 different cellular processes,including DNA and protein synthesis,enzyme activity,and intracellular signaling.Zn availability is also important for tumor growth and progression because it is an essential component for many enzymes such as carbonic anhydrase and matrix metalloproteinases,which are involved in hypoxia,angiogenesis,cell proliferation,and metastasis.Intracellular Zn homeostasis is tightly regulated through the integration of Zn transporting mechanisms,including zinc influx,efflux and intracellular retention.A large number of studies have confirmed that the deregulation of Zn homeostasis is related to the occurrence and metastasis of pancreatic carcinoma.Therefore,the abnormal regulation of intracellular zinc homeostasis plays an important role in the occurrence and development of pancreatic carcinoma.
