We have previously shown that ARG2 expression was increased in most malignant thyroid tumors, but absent in benign lesions and normal tissues. Small interfering RNA knockdown was used to investigate the role of ARG2 in a thyroid carcinoma cell line. ARG2 knockdown decreased eNOS expression as well as the expression of eNOS-related genes (p21, Akt1, HIF-1,(More)
Germline mutations in codon 918 of exon 16 of the RET gene (M918T) are classically associated with multiple endocrine neoplasia type 2B (MEN 2B) with highly aggressive medullary thyroid cancer (MTC), pheochromocytoma and a unique phenotype. The objectives of this study are to describe the rare M918V RET mutation discovered in 8 MTC kindreds from Brazil(More)
