Immunofluorescence (IF) staining revealed the expression of autophagy-related protein LC3B in tumor vascular endothelial cells across several cancer types, including hepatocellular carcinoma (HCC), non-small cell lung cancer (NSCLC), glioblastoma (GBM), gastric cancer (GC), and colorectal cancer (CRC). The gene discussed is MAP1LC3B; the disease is non-small cell lung carcinoma.
