BSG and squamous cell lung carcinoma: The percentages of CD147‐K148me2‐positive tissues were 65% in lung adenocarcinoma (LUAD) and 71% in lung squamous cell carcinoma (LUSC); these values were slightly lower than those of CD147, and both molecules were barely detectable in para‐carcinoma tissues (Figure 1A–C; Figure S3A–C, Supporting Information).
