Radiation-induced autophagy in normal and cancer cells: towards novel cytoprotection and radio-sensitization policies?

abstract：:Numerous cardiomyocytes were found to show autophagic vacuolar degeneration in the UM-X7.1 hamster model of human dilated cardiomyopathy, and autophagy-related proteins--i.e., ubiquitin, cathepsin D and Rab7--were upregulated in those hearts. Importantly, Evans blue-positive cardiomyocytes with leaky plasma membranes ...

abstract：:Microtubule-associated protein light chain 3 (LC3) is now widely used to monitor autophagy. One approach is to detect LC3 conversion (LC3-I to LC3-II) by immunoblot analysis because the amount of LC3-II is clearly correlated with the number of autophagosomes. However, LC3-II itself is degraded by autophagy, making int...
