摘要: mRNA isolated from medullary carcinoma of the thyroid (MTC) in six patients with inherited multiple endocrine neoplasia syndrome type 2 and cervical metastases two sporadic MTC was screened for presence calcitonin proopiomelanocortin (POMC) related sequences by blot hybridization analysis. All tumors were found to contain hybridizing a calcitonin–specific probe. However, POMC-related detected only RNA preparations purified MTC. Compared POMC occurring human pituitary gland, size species POMC-specific probe larger ofboth investigated. cDNA complementary one cloned into pBR 322. From this library plasmids containing inserts which completely homologous sequence 190 nucleotides 3′-end mRNA. In conclusion, 1) nucleotide sequ...
