Megjegyzések:CD24 is a small molecular weight cell-surface protein and an independent marker for poor prognosis in the different type of cancers. We aimed to determine the expression of CD24 in plasma, exosomes and ovarian tissue samples of serous ovarian cancer patients. We collected tissue and blood samples from 21 cases of serous ovarian cancer and eight healthy controls. We used silica adsorption method for isolation of RNA. The cDNA was synthesized using quantitative real-time PCR. We used beta-globin as a housekeeping gene for the normalization of the data. Protein-protein and miRNA networking were analyzed. There was a significant difference in the expression of CD24 in ovarian tissue between controls and patients (0.16?±?0.32 vs. 44.97?±?68.06; p?<?0.01), while CD24 did not show expression in each plasma and exosome samples. There was a correlation in the expression of CD24 and FIGO grading between controls and patients. CD24 expression was detected in exosomes in 38.1% of patients, mainly with FIGO III, and in their plasma in 9.5% of cases. Our network analysis shows LYN, SELP, FGR, and NPM1 proteins are interacting with CD24. Our study demonstrates higher expression of CD24 in ovarian cancer patients' tissue samples, and there is an association with FIGO classification. However, CD24 showed expression only in some cell-free plasma and exosome samples.

Cím:Cell-free, long non-coding RNA as novel biomarker in the diagnosis of ovarian cancer / B. Soltesz, J. Lukács, E. Szilágyi, R. Póka, B. Nagy

Megjegyzések:Background: Ovarian cancer is the fifth leading cause of cancer-associated mortality among women. A reliable, non-invasive diagnostic method may contribute to the early detection of this malignancy. The long non-coding RNAs (lncRNAs) have a significant role in the oncogenesis, metastasis and chemoresistance. The upregulation of Hox transcript antisense intergenic RNA (HOTAIR) was determined in the development of ovarian cancer cells, however, the cell-free HOTAIR expression was not detected from the plasma until now.Materials and methods: Twenty previously untreated ovarian cancer patients (60.60?10.84y; FIGO stages III or IV) and 20 healthy controls (56.70?14.51y) were involved in the study. EDTA blood was drawn; RNA was isolated; cDNA was synthesised and the HOTAIR lncRNA expression were determined by using ExiLERATE LNA? qPCR,for mRNA and long non-coding RNA (Exiqon, USA). ACTB was used as reference gene. Student t-test was applied for the statistical calculations.Results: Higher expression of HOTAIR was detected in the samples of patients with ovarian cancer (1.89?2.39) than in healthy controls (1.39?1.48) but the difference was no significant (p=0.432).Conclusion: We determined the concentration of the cell free HOTAIR lncRNA from the plasma of ovarian cancer patients and healthy controls. There was no significant difference in the expression of the analysed lncRNA; but this is the first study to analyse the cell-free HOTAIR expression among Hungarian ovarian cancer patients. We would like to extend our study on higher number of cases as this lncRNA seem to be novel biomarker for the diagnosis of ovarian cancer.
