Decrease in calcitonin and parathyroid hormone mRNA levels and hormone secretion under long-term hypervitaminosis D3 in rats
(Universidad de Murcia. Departamento de Biología Celular e Histología, 2001-04-25)
In calcium homeostasis, vitamin D3 is a potent serum calcium-raising agent which in vivo regulates both calcitonin (CT) and parathyroid hormone (PTH) gene expression. Serum calcium is the major secretagogue for CT, a hormons ...

Postnatal Fate of the Ultimobranchial Remnants in the Rat Thyroid Gland
(Wiley Periodicals, Inc., 2013-07)
The ultimobranchial follicles (UBFs) areconsidered embryonic remnants from the ultimobran-chial body (UBB). They are follicular structures thatvary in size and appearance depending on the age of therat. ...

Immunohistochemical profiling of the ultimobranchial remnants in the rat postnatal thyroid gland
(Wiley Periodicals, Inc., 2017-05-02)
Ultimobranchial (UB) remnants are a constant presence in the thyroid throughout rat postnatal life; however, the difficulty in identifying the most immature forms from the surrounding thyroid tissue prompted us to search ...

C-cell differentiation in the wall of an aberrant ultimobranchial sinus in the thyroid gland of an old rat
(Wiley, 2022)
Background In mammals, the thyroid gland possesses two types of endocrine cells, follicular cells and C cells, which have different functions but share a similar endodermal origin (although from different regions of the ...

cDNA Sequence and Genomic Structure of the Rat Ret Proto-Oncogene
(Informa Healthcare, 2000-06-01)
The RET proto-oncogene, a member of the Receptor Tyrosine Kinase family, plays a crucial role during the development of the excretory system and the enteric nervous system, as demonstrated by in vivo animal studies and by ...

Comparative study of the primary cilia in thyrocytes of adult mammals
(Anatomical Society, 2015)
Since their discovery in different human tissues by Zimmermann in 1898, primary cilia have been found in the vast majority of cell types in vertebrates. Primary cilia are considered to be cellular antennae that occupy an ...

Thyrotropin-releasing hormone receptor expression in thyroid follicular cells: a new paracrine role of C-cells?
(Universidad de Murcia. Departamento de Biología Celular e Histología, 2005-07-01)
Thyrotropin-releasing hormone (TRH) synthesized in the hypothalamus has the capability of inducing the release of thyroid-stimulating hormone (TSH) from the anterior pituitary, which in turn stimulates the production of ...

Histopathological Features of Pendred Syndrome Thyroids Align with Differences in the Expression of Thyroid‑Specific Markers, Apical Iodide Transporters, and Ciliogenesis Process
(HUMANA PRESS INC, 2022)
Pendred syndrome (PDS) is an autosomal recessive disorder caused by mutations in the gene that encodes pendrin. Pendred thyroid tissue is supposedly altered by the absence of functional pendrin, but it is still unknown ...

Melatonin-synthesizing enzymes and melatonin receptor in rat thyroid cells
(Universidad de Murcia. Departamento de Biología Celular e Histología, 2012-11)
Melatonin is an indoleamine with a wide spectrum of biological activities other than transmitting photoperiod information, including antioxidant, oncostatic, anti-aging and immunomodulatory properties. Although melatonin ...

Primary Cilium in the Human Thyrocyte: Changes in Frequency and Length in Relation to the Functional Pathology of the Thyroid Gland
(Mary Ann Liebert, Inc. Publishers, 2019-04)
Background: Primary cilia (PC) are conserved structures in the adult thyroid gland of different mammals. We have recently described that, in humans, PC are usually present as a single copy per follicular cell emerging ...
