LAMP1 and breast neoplasm: To investigate the occurrence of autophagy in dormant breast tumour cells, we analysed the expression pattern of Microtubule-associated protein 1 A/1B-light chain 3 (MAP1LC3, also known as LC3) and Lysosomal-associated membrane protein 1 (LAMP1) over time in D2.0 R cells on BME (cells remain dormant) and BME plus COL1 matrices (which induces proliferation of the dormant cells)8 (Supplementary Fig. 1).
