YBX1 and lung cancer: To analyze the expression of YBX1 and MUC1 in human lung adenocarcinoma, we first analyzed the Oncomine database and found that there was a significant correlation between the YBX1 and MUC1 mRNA levels in lung cancer patient tissues (r=0.394; p<0.05), especially lung adenocarcinoma tissues(r=0.578; p<0.05; Figure 1A) (35, 36).
