ABSTRACT
Esophageal cancer is one of the common malignant tumors in China.Although it is currently treated by multidisciplinary treatment,esophageal cancer's prognosis is still poor.The occurrence of esophageal cancer is closely related to the metabolism of trace element zinc.Zinc deficiency can induce the development of esophageal cancer by inducing inflammatory reaction and microRNAs imbalance.Zinc ion can play an important role in esophageal cancer by regulating the activity of ion channel.The formed zinc finger protein can function as an oncogene or a tumor suppressor gene in esophageal cancer.Zinc metabolism is accompanied by complex biological changes in the pathogenesis of esophageal cancer,and multiple mechanisms interact and are closely linked.The article reviews the research results of recent years on the mechanism of zinc deficiency,zinc ion-regulated ion channel and zinc finger protein in the development of esophageal cancer.
ABSTRACT
A major goal of mineral nutrition research is to provide information of feed zinc (Zn) utilization efficiency and gross Zn requirements as affected by changing rearing conditions. This can be achieved only by applying precise experimental models that acknowledge the basic principles of Zn metabolism. This review article summarizes the most important aspects of Zn homeostasis in monogastric species, including molecular aspects of Zn acquisition and excretion. Special emphasis is given to the role of the skeleton as well as the exocrine pancreas for animal Zn metabolism. Finally, we discuss consequences arising from these physiological principles for the experimental design of trials which aim to address questions of Zn requirements and bioavailability.
