From: Expression patterns of mechanosensitive ion channel PIEZOs in irreversible pulpitis
The mRNA expression levels of pain markers NPY, CALCA, CALCB, and TAC1 and the correlations between PIEZOs and these pain markers. A-D The mRNA expression levels of NPY, CALCA, CALCB, and TAC1 in normal pulp tissues (n = 21) and inflamed pulp tissues (n = 15) were presented, respectively. E The correlation of the mRNA expression levels between PIEZO1 and NPY, as well as PIEZO2 and NPY, was assessed using Spearman’s correlation analysis. F The correlation of the mRNA expression levels between PIEZO1 and CALCA, as well as PIEZO2 and CALCA, was assessed using Spearman’s correlation analysis. G The correlation of the mRNA expression levels between PIEZO1 and CALCB, as well as PIEZO2 and CALCB, was assessed using Spearman’s correlation analysis. H The correlation of the mRNA expression levels between PIEZO1 and TAC1, as well as PIEZO2 and TAC1, was assessed using Spearman’s correlation analysis. * represents P < 0.05; ** represents P < 0.01; *** represents P < 0.001
