The function of mammalian tissues to their physiological functions depends on the support of various nutrients. We know that changes in human metabolites are involved in the pathological process of cancer, but we know very little about which nutrients support the high-speed growth of whole malignant cells. Amino acids are essential nutrients for most cancer cells. Cancer cells can take extracellular protein metabolites as a source of amino acids through pinocytosis, which is an important source of nutrition for pancreatic cancer cells. However, whether the amino acid nutrient source of this pinocytosis method can maintain the amino acid level in pancreatic cancer cells remains to be further studied.
