  1. Autophagic tumor stroma model of cancer

    Merge to Reverse Warburg Effect date January 2011 orphan date September 2010 The autophagic tumor stroma model of cancer proposes that epithelium epithelial cancer cells use oxidative stress as a weapon to extract recycled nutrients from adjacent stromal cell stromal fibroblast s i.e., connective tissue cells. ref name pmid20861672 ref name pmid20818174 ref name pmid20855962 ref name pmid20864819 ref name pmid20814239 ref name pmid20431349 ref name pmid20861671 ref name pmid19411449 ref name pmid19465642 ref name pmid19411448 The theory The theory posits that oxidative stress in cancer associated fibroblasts forces these cells to eat themselves, by a process called autophagy or self cannibalism . The resulting recycled nutrients, derived from catabolism in the tumor stroma, are then used to power the anabolic growth of cancer cells. Thus, cancer is a disease of energy imbalance , resulting from the vectorial and unilateral transfer of energy rich nutrients from the tumor stroma to cancer cells. This explains the phenomenon of cancer associated cachexia systemic wasting , in which patients with advanced cancer cannot maintain their normal body weight . Oxidative stress in cancer associated fibroblasts also has other consequences. The amplification of ROS reactive oxygen species production feeds back upon the epithelial cancer cells, inducing DNA damage DNA repair Double strand breaks double strand breaks and aneuploidy abnormal chromosome number , which are characteristic of genomic instability. Thus, ROS production in the stroma fuels cancer cell evolution via a process of random ... UE, Howell A, Sotgia F, Lisanti MP title The autophagic tumor stroma model of cancer Role ...

Infiltration is confined to the surgical flap interface with no posterior or anterior extension, and overlying epithelium most often remains intact.
