Thus, 1,25-(OH)2D3 and its analogues de-repress the key autophagic MAP1LC3B (LC3B) gene and activate 5′-AMP-activated protein kinase (AMPK) via increased cytosolic Ca2+ and activation of Ca2+/calmodulin-dependent protein kinase β in breast carcinoma cells [172]. This evidence concerns the gene MAP1LC3B and breast carcinoma.
