Also, the same study demonstrated an increased expression of MUC1 with increasing grade of papillary carcinoma i.e. 37.5% of grade 1 cases, 75% of grade 2 cases and 88.9% of grade 3 cases and this difference in expression was statistically significant (P<0.01) [15]. Here, MUC1 is linked to thyroid gland papillary carcinoma.
