Altered Peptidase Activities in Thyroid Neoplasia and Hyperplasia
Figure 1
Enzymatic activities: activity in thyroid nodular hyperplasia (TNH), follicular thyroid adenoma (FTA), and papillary thyroid carcinoma (PTC) tissues. Values are means ± SE of peptidase activity recorded as pmol of units of peptidase (UP) per milligram of protein. (a) DPPIV/CD26: a value of was considered statistically significant. *Kruskal-Wallis test, . **The activity was higher in PTC than in FTA (Mann-Whitney test, ) and TNH (Mann-Whitney test, ). (b) AlaAP: a value of was considered statistically significant. *Kruskal-Wallis test, . **The activity was higher in PTC than in FTA (Mann-Whitney test, ) and TNH (Mann-Whitney test, ). (c) AspAP: a value of was considered statistically significant. *Kruskal-Wallis test, . **The activity was higher in PTC than in FTA (Mann-Whitney test, ) and TNH (Mann-Whitney test, ).
