The heat map showed the relative median expression of LAMB3 and genes positively correlated with LAMB3 in eight common solid tumors, PAAD (pancreatic adenocarcinoma), COAD (colon adenocarcinoma), LIHC (liver hepatocellular carcinoma), PRAD (prostate adenocarcinoma), LUAD (lung adenocarcinoma), THCA (thyroid carcinoma), BRCA (invasive breast carcinoma), and BLCA (bladder urothelial carcinoma), based on datasets from the TCGA database; LAMB3 was positively correlated with PDAC (Fig. 1c). Here, LAMB3 is linked to invasive breast carcinoma.
