Thyroid hormones exert their effects through alpha (TRα1) and beta (TRβ1 and TRβ2) receptors. Here we describe a child with classic features of hypothyroidism (growth retardation, developmental retardation, skeletal dysplasia, and severe constipation) but only borderline-abnormal thyroid hormone levels. Using whole-exome sequencing, we identified a de novo heterozygous nonsense mutation in a ge...
Thyroid hormone (T3) resistance is inherited in most cases in an autosomal dominant manner. The disorder is characterized by elevated free thyroid hormone levels and partial resistance to thyroid hormone at the cellular level. Distinct single amino acid substitutions in the ligand binding domain of the beta form of the thyroid hormone receptor have been described in two kindreds with this disor...
Immunohistochemistry (IHC) is currently considered the method of choice for steroid hormone receptor status evaluation in human breast cancer and, therefore, it is commonly utilized for assessing canine mammary tumors. In case of low hormone receptor expression, IHC is limited and thus is complemented by molecular analyses. In the present study, a multiplex bDNA assay was evaluated as a method ...
BACKGROUND Predilection of juvenile angiofibromas in adolescent boys has prompted the hypothesis of hormone-dependent tumor growth. However, knowledge on expression and function of sex hormone receptors in juvenile angiofibromas is still sparse and inconsistent. METHODS Transcript and protein expression of sex hormone receptors in juvenile angiofibromas was studied by quantitative reverse tra...
The oestrogen receptor is a member of the nuclear receptor family of transcription factors which, on binding the steroid hormone 17beta-oestradiol, interacts with co-activator proteins and stimulates gene expression. Replacement of a single tyrosine in the hormone-binding domain generated activated forms of the receptor which stimulated transcription in the absence of hormone. This increased ac...
We have stably introduced expression vectors for the glucocorticoid receptor and a sensitive, hormone-responsive reporter (mouse mammary tumor virus-luciferase) into a human breast carcinoma-derived cell line. Employing this cell line, we have conducted a detailed examination of the induction of glucocorticoid-regulated genes and the phosphorylation of glucocorticoid receptor following pharmaco...
