AB  - Background: The aim of this study was to compare serum sclerostin concentrations in patients with thyroid dysfunction with euthyroid control subjects and to assess the relationship between sclerostin and markers of bone metabolism (osteocalcin and beta-cross-laps). Methods: The study included 30 patients with thyroid dysfunction (hypothyroidism, hyperthyroidism and subclinical hyperthyroidism) and ten euthyroid controls. Free thyroxine (FT4) was measured by radioimmunoassay, while thyroid stimulating hormone (TSH) concentration was determined immunoradiometrically. We used an ELISA kit to determine the sclerostin level. The electrochemiluminescence method was applied for measuring the bone markers. Results: Sclerostin levels were significantly lower in hypothyroid patients (p=0.009) and significantly elevated in hyperthyroid patients (p=0.008) compared to control values. Hyperthyroid patients also had higher sclerostin than patients with subclinical hyperthyroidism (p=0.013). Sclerostin concentrations were negatively correlated with TSH levels (r=-0.746, p lt 0.001), but positively with FT4 (r=0.696, p  lt  0.001). Moreover, sclerostin was positively associated with osteocalcin (r=0.605, p=0.005) and beta-cross-laps levels (r=0.573, p=0.008) in all thyroid patients. Conclusions: Serum sclerostin is significantly affected in subjects with thyroid dysfunction. Both sclerostin and thyroid status affect bone homeostasis, which is reflected through the significant correlations with osteocalcin and beta-cross-laps.
AB  - Uvod: Cilj ove studije bio je da uporedimo serumske koncentracije sklerostina kod pacijenata sa disfunkcijom štitaste žlezde u odnosu na eutiroidne kontrolne ispitanike, i da procenimo odnos između sklerostina i markera koštanog metabolizma (osteokalcina i beta-cross-lapsa) u istoj populaciji. Metode: Studijom je obuhvaćeno 30 pacijenata sa disfunkcijom štitaste žlezde (hipotireozom, hipertireozom i supkliničkom hipertireozom) i 10 eutiroidnih kontrola. Slobodni tiroksin (FT4) meren je radioimunološkom metodom, dok je koncentracija tireostimulišućeg hormona (TSH) određivana imunoradiometrijski. Za merenje nivoa sklerostina koristili smo ELISA-test. Metoda elektrohemiluminiscencije primenjena je za merenje koncentracije koštanih markera. Rezultati: Nivo sklerostina bio je značajno niži kod bolesnika sa hipotireozom (p = 0,009) odnosno značajno viši kod bolesnika sa hipertireozom (p = 0,008) u poređenju sa vrednostima kod eutiroidnih kontrolnih ispitanika. Pacijenti sa hipertireozom su takođe imali statistički značajno viši nivo sklerostina u odnosu na bolesnike sa supkliničkom hipertireozom (p = 0,013). Pokazana je negativna korelacija koncentracije sklerostina i TSH (r = -0,746, p  lt  0,001), odnosno pozitivna korelacija sa FT4 (r = 0,696, p  lt  0,001) kod pacijenata sa tireoidnom disfunkcijom. Štaviše, sklerostin pozitivno korelira sa koncentracijom osteokalcina (r = 0,605, p = 0,005) i beta-cross-lapsa (r = 0,573, p = 0,008) kod ovih pacijenata. Zaključak: Serumski nivoi sklerostina izmenjeni su kod osoba sa disfunkcijom štitaste žlezde. Sklerostin zajedno sa tireoidnim statusom utiče na koštani metabolizam, što se ogleda u njegovoj značajnoj korelaciji sa osteokalcinom i beta-cross-lapsom.

AB  - In this study, a series of synthesized 3-(4-substituted benzyl)-5-isopropyl-5-phenylhydantoin derivatives as a potential antiproliferative and antimigratory agents were investigated. The possible antitumor mechanisms of investigated hydantoin derivatives were examined on human breast cancer cell line MDA-MB-231. The cells were treated with different concentrations of compounds (from 0.01 mu M to 100 mu M) during 24 h and 72 h. The proliferation index, nitric oxide production, apoptosis rate, and migration capacity were measured. The cell invasion potential was examined by measuring the level of MMP-9 and COX-2 gene expression. All tested compounds expressed antiproliferative activity and induced dose- and time-dependent increase in the level of nitrites. The investigated molecules significantly decreased cell survival rate, migration capacity and the expression levels of genes included in the process of tumor invasion. Obtained data suggest that the tested hydantoin derivatives express considerable antitumor activity by reducing cell division rate, elevating apoptosis level, and inhibiting the motility and invasiveness of breast cancer cells. The results obtained in this study indicate that investigated compounds express potential as a novel chemotherapeutic agents against breast cancer growth and progression. (C) 2020 The Author(s).
