The RET (rearranged during transfection) protooncogene encodes a single pass transmembrane receptor that is expressed in cells derived from the neural crest and the urogenital tract. As part of a cell-surface complex, RET binds glial derived neurotrophic factor (GDNF) ligands in conjunction with GDNF-family alpha co-receptors (GFRalpha). Ligand-induced activation induces dimerization and tyrosi...

Activating mutations of the RET proto-oncogene are associated with inherited syndromes, multiple endocrine neoplasia (MEN2A/2B) and with familial and sporadic medullary thyroid cancer (MTC). Single base pair missense mutations in the extracellular Cys-rich domain are responsible for most MEN2A and familial MTC (FMTC) cases. Rarely, somatic deletions and germline duplications have been described...

Background: Familial Medullary Thyroid Cancer (FMTC) is hereditary in 25% of cases. Patients with an inherited form FMTC usually have a germline mutation the RET proto-oncogene (10q11.2); these mutations generally occur exons 10 (codons 618 and 620) 11 630, 631, 634).
 Methods: A narrative review articles focused on pathology familial medullary thyroid cancer was carried out using next dat...

Clouds often contaminate remote sensing images, which leads to missing land feature information and subsequent application degradation. Low-rank tensor completion has shown great potential in the reconstruction of multi-temporal images. However, existing methods ignore different low-rank properties spatial temporal dimensions, such that they cannot utilize adequately. In this paper, we propose ...

BACKGROUND The multiple endocrine neoplasia 2 (MEN 2) syndromes [MEN 2A, MEN 2B, and familial medullary thyroid carcinoma (FMTC)] are caused by germline mutations of the RET protooncogene. Because 85% of MEN 2A patients and 30% of FMTC patients have mutations at codon 634, the recommended molecular analyses begin at exon 11, where codon 634 is located. METHODS We scanned codon 634 of the RET ...

Note Medullary thyroid cancers (MTC) are rare tumors of neuroendocrine origin that arise from parafollicular C cells which secrete a variety of peptides and hormones including calcitonin. As opposed to the more common papillary and follicular thyroid cancer subtypes, MTC represents a rare and under-characterized form of cancer, and can cause death if untreated (Taccaliti et al., 2011). MTC can ...

The RET (rearranged during transfection) protooncogene encodes a single pass transmembrane receptor that is expressed in cells derived from the neural crest and the urogenital tract. As part of a cell-surface complex, RET binds glial derived neurotrophic factor (GDNF) ligands in conjunction with GDNF-family α co-receptors (GFRα).

We investigatedthe transformingactivityofthe ret proto-oncogenewith a mutation in cysteine 609, 611, 618, 620, 630, or 634 detected in patients with multiple endocrine neoplasia type 2A (MEN 2A), familial meduilary thyroid carcinoma (FMTC), or Hirschsprung's disease. Of these cysteine mutations, codon 634 mutations are known to he correlated with the development of MEN 2A, whereas codon 609, 61...

Patients with hereditary medullary thyroid carcinoma (MTC) associated with multiple endocrine neoplasia (MEN) types 2A and 2B and familial MTC (FMTC) have mutations in the RET proto-oncogene. Approximately 40 percent of patients with papillary thyroid carcinoma (PTC) typically have either intrachromosomal or extrachromosomal rearrangements that join the promoter and NH(2)-terminal domains of un...

The RET proto-oncogene has been identified as the multiple endocrine neoplasia type 2 disease gene. An association between specific RET mutation and disease phenotype has been reported. We present the phenotype-genotype of 12 Greek families with multiple endocrine neoplasia type 2A (MEN 2A) or familial medullary thyroid carcinoma (FMTC). Seventy members were studied and DNA analysis for RET mut...
