LC3A-positive light microscopy detected patterns of autophagy and prognosis in operable breast carcinomas.
Autophagy is a self-degradation mechanism by which cells recycle their own cytoplasmic constituents and dispose of excess or defective organelles after starvation and oxygen deprivation. An antibody to the microtubule-associated protein 1 light chain 3 (LC3A), recognizing both the soluble (LC3A-I) and the membrane-bound form (LC3A-II) of the protein, was used to detect autophagic activity in 102 breast carcinomas. Three distinct patterns were recognized: (1) diffuse cytoplasmic, (2) cytoplasm...Expand abstract
