摘 要：In solid tumors,the development of vasculature is,to some extent,slower than the proliferation of the different types of cells that form the tissue,both cancer and stroma *** a consequence,the oxygen availability is compromised and the tissue evolves toward a condition of *** presence of hypoxia is variable depending on where the cells are localized,being less extreme at the periphery of the tumor and more severe in areas located deep within the tumor ***,the cells do not *** pathways that are critical for cell fate such as endoplasmic reticulum stress,apoptosis,autophagy,and others are all involved in cellular responses to the low oxygen availability and are orchestrated by hypoxia-inducible *** stress and inflammation are critical conditions that develop under *** with changes in cellular bioenergetics,all contribute to cell ***,cell-to-cell interaction is established within the tumor such that cancer cells and the microenvironment maintain a bidirectional ***,the release of extracellular vesicles,or exosomes,represents short and long loops that can convey important information regarding invasion and *** a result,the tumor grows and its malignancy ***,one of the most lethal tumors is pancreatic *** paper reviews the most recent advances in the knowledge of how cells grow in a pancreatic tumor by adapting to *** the physiological processes that help the tumor increase its size and their regulation will be of major relevance for the treatment of this deadly tumor.
