Interestingly, only a few significant associations between mucin mRNA expression and the presence of a comorbidity were found, including MUC4 mRNA expression with lymphoproliferative disease, MUC5B, and MUC6 mRNA expression with hypertension, MUC16 mRNA expression with malignancy, and MUC20 mRNA expression with diabetes (Figure 7A). Here, MUC5B is linked to hypertensive disorder.
