Breakpoint cluster region abelson fusion oncoprotein (BCR-ABL) targeted tyrosine kinase inhibitors (TKIs) are widely used in long-term medications of hematological malignancies. Numerous clinical observations confirmed that these drugs significantly modify the physiology of bone tissue as a side effect. Currently, there are numerous contradictory results regarding the complex effects of TKIs on bone metabolism, as well as there is no clear evidence to explain them, either in t...

Objectives: We previously published the result of CYP24A1 gene expression in one hundred, solely papillary thyroid carcinoma (PTC) compared to its own tumour free control from the same patient. We report an increase in CYP24A1 gene transcription in more than half of analysed PTCs. Elevated CYP24A1 protein expression was also observed in the cancerous tissue section compared to peritumoural normal thyroid tissue. In the present study we aimed to examine CYP24A1 gene transcripti...

Background: The ’three-genes’ (SFN, MRC2, HMGA2) might have direct role in various cancer progression and malignant thyroid conditions. We previously reported an increased expression of 1,25-D3 neutralizing enzyme, (24-hydroxylase – CYP24A1) as a possible novel marker gene in thyroid carcinoma. In this study, we examined the transcription activity of CYP24A1 and ‘three-genes’ in four functional subgroups of papillary thyroid tumor (PTC)....

Cold nodules are one of the most common findings on scintiscans and ultrasound examinations of the thyroid gland. About 5-10% of these nodules turn out to be histologically malignant. Our aim was to examine the predictive value of somatogenetic alterations associated with thyroid cancer in FNA samples of thyroid cold nodules being citologically benign at the beginning of the study. These alterations included single nucleotide mutations (BRAF, HRAS, NRAS, KRAS) and genetic tran...

Thyroid cancer is the most common malignancy of endocrine organs and its incidence is steadily growing worldwide. Approximately 80% of differentiated thyroid tumors are papillary carcinomas. Next-generation sequencing (NGS) allows for high-throughput sequencing analysis of large number of samples at a time in a cost effective manner. We have developed a targeted sequencing parallel testing panel for multiple mutations in genes involved in thyroid cancer pathology. A custom-mad...

Cold nodules are one of the most common findings on scintigraphic examinations of the thyroid gland. About 5–10% of these nodules turn out to be histologically malignant. Our aim was to examine some somatogenetic alterations associated with thyroid cancer in FNA samples of the thyroid. These alterations included single nucleotide mutations (BRAF, HRAS, NRAS, KRAS) and genetic translocations (RET/PTC1, RET/PTC3, PAX8ex7/PPARgamma, PAX8ex9/PPARgamma). The SNPs were tested b...
