Showing differences between the three groups of β-catenin-immunostained sections. Light microscopy (LM) images of β-catenin immunostaining in the tongue papillae:100x magnification. (a) Control group (Group I) shows strong positive immunostaining for β-catenin in the tongue papillae. (b) High-fat diet group (Group II) displays mild immunostaining in the tongue papillae.(c) Low-calcium diet group (Group III) exhibits minimal to no immunostaining in the filiform papillae.
