Metabolomics provides new information on the changes occurring in thyroid tumours
Metabolomics is a part of systems biology dealing with the determination of qualitative and quantitative profile of low molecular weight compounds (metabolites) present in body fluids and tissues of living organisms. Metabolic composition is strongly dependent on the state of homeostasis and any deregulation should affect it. For this reason, there is now increased interest in metabolomics as a potential tool to support cancer research. At the same time the analysis of metabolic pathways involved in the process of carcinogenesis provides the possibility of a more complete understanding of the mechanisms that are critical for tumour biology. In this study, 1H NMR measurements were performed …
Follicular adenomas exhibit a unique metabolic profile. ¹H NMR studies of thyroid lesions.
Thyroid cancer is the most common endocrine malignancy. However, more than 90% of thyroid nodules are benign. It remains unclear whether thyroid carcinoma arises from preexisting benign nodules. Metabolomics can provide valuable and comprehensive information about low molecular weight compounds present in living systems and further our understanding of the biology regulating pathological processes. Herein, we applied ¹H NMR-based metabolic profiling to identify the metabolites present in aqueous tissue extracts of healthy thyroid tissue (H), non-neoplastic nodules (NN), follicular adenomas (FA) and malignant thyroid cancer (TC) as an alternative way of investigating cancer lesions. Multivar…
Serum and urine 1H NMR-based metabolomics in the diagnosis of selected thyroid diseases
AbstractEarly detection of nodular thyroid diseases including thyroid cancer is still primarily based on invasive procedures such as fine-needle aspiration biopsy. Therefore, there is a strong need for development of new diagnostic methods that could provide clinically useful information regarding thyroid nodular lesions in a non-invasive way. In this study we investigated 1H NMR based metabolic profiles of paired urine and blood serum samples, that were obtained from healthy individuals and patients with nodular thyroid diseases. Estimation of predictive potential of metabolites was evaluated using chemometric methods and revealed that both urine and serum carry information sufficient to d…
