TRs are transcription factors that regulate cell proliferation, differentiation, and apoptosis. They are cellular homologs of the transcriptionally inactive viral oncogene v-erbA. We tested the hypothesis that the functions of TRs could be impaired in cancer tissues as a result of aberrant expression and/or somatic mutations. As a model system, we selected(More)
Human renal clear cell carcinoma (RCCC) accounts for up to 2% of human cancers. To find out if thyroid hormone (T3) and its receptors (TRs) play a role in tumorigenesis of RCCC, the expression of TRs was evaluated on mRNA and protein level. It was found that TRalpha (both alpha1 and alpha2) mRNA amount was significantly decreased in tumors while compared(More)
Thyroid hormone (T(3)) regulates proliferation and differentiation of cells, via its nuclear receptors (TRs). These processes have been shown to be abnormally regulated during carcinogenesis. We have previously found aberrant expression of TRalpha and TRbeta mRNAs in renal clear cell carcinoma (RCCC), suggesting possible involvement of TRs in the(More)
Carbohydrate (CHO)-restricted diets have been recommended for weight loss and to prevent obesity, but their long-term effects have not been fully elucidated. This study was designed to evaluate the effect of long-term (>1 year) consumption of a low-CHO high-fat diet ("The optimal diet," developed by Dr Kwaśniewski referenced herein) on lipid profile,(More)
OBJECTIVE The development and severity of Graves' ophthalmopathy (GO) may result from a complex interplay of genetic and environmental factors. The aim of this study was to investigate the association of cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) gene polymorphism and non-genetic factors (age, sex, cigarette smoking) with GO in two different(More)
Sialylation of cell components is an important immunomodulating mechanism affecting cell response to hormones and adhesion molecules. To study alterations in sialic acid metabolism in Graves' disease (GD) we measured the following parameters in various human thyroid tissues: lipid-bound sialic acid (LBSA) content, ganglioside profile, total(More)
The presence of antithyroid plasma membrane antibodies (ATMA) has been detected in 97% of patients with untreated hyperthyroid Graves' disease, 85% of methimazole treated hyperthyroid Graves' disease, 25% of Hashimoto's thyroiditis and 6.9% of patients with toxic nodular goitre. The ATMA index was negative in all healthy blood donors, in patients with(More)
The ability of protein A from Staphylococcus aureus to interact with Fc fragments of IgG was used to estimate the antithyroid plasma membrane antibodies in sera of patients with Graves' disease. The results were expressed as an antithyroid plasma membrane antibodies (ATMA) index. The ATMA index estimated in 60 healthy blood donors varied from 0.57 to 1.28,(More)
