ACE2 and thyroid tumor: Most thyroid neoplasms had lower ACE2 expression than adjacent tissue, and the expression levels seemed to be more accumulated in the lower tercile, i.e., the second tercile (2T) of thyroid neoplasms was 0.257 when compared to the 1T of adjacent tissue of 0.253 (Figure 7 Top Panel), whereas Furin mRNA expression levels in thyroid lesions seemed to be more accumulated in the third tercile (Figure 7 Lower Panel) compared to the distribution observed in adjacent tissue, i.e., 1T was 0.029 and 2T was 0.023, respectively.
