This oncogenic autophagy is also observed in pancreatic ductal adenocarcinoma as suppression of autophagy through the direct interaction between ubiquitin-like protein 4A (UBL4A) and lysosome-associated membrane protein 1 (LAMP-1) inhibits pancreatic tumor migration and invasion [54]. This evidence concerns the gene LAMP1 and pancreatic ductal adenocarcinoma.
