We used Gene Expression Profiling Interactive Analysis (GEPIA), Breast Cancer Gene-Expression Miner v4.7 (bc-GenExMiner v4.7), UALCAN, The Human Protein Atlas (HPA), Gene Expression-Based Outcome for Breast Cancer Online (GOBO), Cancer Cell Line Encyclopedia (CCLE), SpatialDB, and Tumor Immune Estimation Resource (TIMER) databases to evaluate the LMAN2 expression. This evidence concerns the gene LMAN2 and neoplasm.
