Plasma exosomal miRNA-205 can be used for early diagnosis and prognostic evaluation of ovarian cancer

Abstract Background Ovarian cancer (OC) is a serious threat to women's health around the world and new biomarkers are urgently needed for early detection. Our previous published research have confirmed that miR-205 can promote the invasion and metastasis of OC cells by inhibiting the expression of the tumor suppressor gene TCF21. This study is based on the previous work, using exosomal liquid biopsy technology to detect the expression levels of the four genes miR-205, CA125, HE4 and TCF21 in the plasma exosomes of OC patients; at the same time, combined with the clinicopathological parameters of OC patients data analysis aims to provide efficient and non-invasive laboratory testing basis for the early diagnosis of OC. Methods Collected 36 OC patients diagnosed in local hospitals from September 2020 to July 2021 as OC group, selected 31 cases of surgically diagnosed ovarian benign lesions for benign group and 32 healthy people who underwent physical examination during the same period as a control group, and used transmission electron microscope (TEM), western blotting (WB) and nanoparticle tracking analysis (NTA) to identify after extracting plasma exosomes from kits. The expression levels of miR-205, CA125, HE4 and TCF21 genes in plasma exosomes were detected by real-time fluorescence quantitative PCR (qRT-PCR) method. At the same time, combined with the relationship between clinical pathological parameters in OC patients, the Receiver Operating Characteristic (ROC) curves were used to evaluate the diagnostic efficacy of plasma exosomal miR-205, CA125, HE4 and TCF21 for OC. Results Plasma exosomes were successfully isolated; the expression level of plasma exosomal miR-205 in the OC group was higher than that of the benign group and the control group, and the difference was statistically significant (P < 0.05); plasma exosomal miR-205 was elevated during the III-IV period of OC and lymph node metastasis; combined detection of plasma exosomal miR-205 can improve the diagnostic ability of OC. Conclusion The plasma exosomal miR-205 can be used as a potential tumor biomarker to improve the diagnostic effectiveness of OC.

Background: This study aimed to investigate the expression levels of microRNA (miRNA)-125b in serum exosomes and its diagnostic efficacy for asthma severity. Methods: The study included 80 patients with untreated asthma and 80 healthy volunteers. The patients were divided into 4 groups according to disease severity: 20 with the intermittent state, 20 with the mildly persistent state, 20 with the moderately persistent state, and 20 with the severely persistent state. The expression levels of miRNA-125b in serum exosomes of each group were detected using a quantitative polymerase chain reaction and compared. The Spearman correlation analysis was used to study the correlation between the expression levels of miRNA-125b in serum exosomes and asthma severity. The diagnostic efficacy of the expression levels of miRNA-125b in exosomes for asthma severity was evaluated using the Receiver Operating Characteristic (ROC) curve. Results: The expression levels of miRNA-125b in serum exosomes of patients with intermittent, mildly persistent, moderately persistent, and severely persistent asthma were all higher than those in the healthy control group, with statistically significant differences. The expression levels of miRNA-125b were also statistically significantly different among patients in each group. The Spearman correlation analysis showed a positive correlation of the relative expression of miRNA-125b in serum exosomes with asthma severity. The area under the ROC curve of the diagnostic efficacy of miRNA-125b in serum exosomes for patients with intermittent, mildly, moderately, and severely persistent asthma was 0.7770, 0.8573, 0.9111, and 0.9995, respectively. Conclusion: The expression levels of miRNA-125b in serum exosomes had a high diagnostic efficacy and might serve as a noninvasive diagnostic marker for asthma severity.

Abstract Alzheimer’s disease (AD) is a progressive neurodegenerative disease and chronic illness with long preclinical phases and a long clinical duration. Until recently, a lack of potential therapeutic agents against AD was the primary focus of research, which resulted in less effort directed towards developing useful diagnostic approaches. In this study, we developed a WO2002/088706 kit that is composed of fluorescent nanoparticles for the early detection of AD. We provided a fluorescent nanoparticle for detecting markers and a kit for the early diagnosis of AD. The kit consists of a probe molecule comprising an oligonucleotide capable of detecting one or more AD-specific microRNAs (miRNAs) and biomarkers related to AD. Through screening, we selected miR-106b, miR-146b, miR-181a, miR-200a, miR-34a, miR-124b, miR-153, miR-155, Aβ1-42 monomer (mAβ), Aβ1–42 oligomer (oAβ), UCHL1, NLRP3, Tau, STAT3, SORL1, Clusterin, APOE3, APOE4, Nogo-A, IL-13, and Visfatin to serve as AD- and inflammation-related markers. For detection of kit-binding properties, we checked the expression levels of amyloid beta (Aβ), tau protein, and inflammatory mediators in APP/PS/ApoE knockdown (KD) mice and a control group using co-localisation analysis conducted with a confocal microscope. Using a similar approach, we checked the expression levels of miRNAs in HT22 cells. Finally, we used the plasma from AD patients to confirm that our fluorescent nanoparticles and the WO2002/088706 kit will provide a possible early diagnosis to serve as an AD detector that can be further improved for future studies on targeting AD.

Abstract Background: Increasing evidence has been confirmed that small nucleolar RNAs (SnoRNAs) play critical roles in tumorigenesis and exhibit prognostic value in clinical practice. However, there is short of systematic research on SnoRNAs in ovarian cancer (OV).Material/methods: 379 OV patients with RNA-Seq and clinical parameters from TCGA database and 5 paired clinical OV tissues were embedded in our study. Cox regression analysis was used to identify prognostic SnoRNAs and construct prediction model. SNORic database was adopted to examine the copy number variation of snoRNAs. ROC curves and KM plot curves were applied to validate the prediction model. Besides, the model was validated in 5 paired clinical tissues by real-time PCR, H&E staining and immunohistochemistry. Results: A prognostic model was constructed on the basis of SnoRNAs in OV patients.Patients with higher RiskScore had poor clinicopathological parameters, including higher age, larger tumorsize, advanced stage and with tumor status. KM plot analysis confirmed that patients with high RiskScore had poorer prognosis in subgroup of age, tumor size and stage. 7 of 9 snoRNAs in the prognostic model had positive correlation with their host genes. Moreover, 5 of 9 snoRNAs in the prognostic model correlated with their CNVs, and SNORD105B had the strongest correction with its CNVs. ROC curve showed that the RiskScore had excellent specificity and accuracy. Further, H&E staining and immunohistochemistry of Ki67, P53 and P16 were confirmed that patients with higher RiskScore are more malignant. Conclusions: In summary, we identified a nine-snoRNAs signature as an independent indicator to predict prognosis of OV, providing a prospective prognostic biomarker and potential therapeutic targets for ovarian cancer.

Abstract Background:The greatest complication of Kawasaki disease (KD) is coronary artery injury, and the requirement for early diagnosis and treatment is paramount. Thus, markers of vascular endothelial injury are of important clinical significance. Methods:According to our diagnostic criteria, blood samples were collected from 43 patients with KD, who were then divided into coronary artery lesions (CALs) and non-CALs (NCALs) groups according to their Z-score. As the control group, an additional 26 blood samples were collected from healthy children. Flow cytometry (FCM) and enzyme-linked immunosorbent assays (ELISA) were used to detect the expression levels of plasma endothelial microparticles (EMPs) and von Willebrand factor (vWF). Results:The expression levels of plasma CD31+/CD42b-EMPs, CD105+/CD54+EMPs, and vWF were higher in children with KD than those in the control group, and the differences were statistically significant (P<0.05).Also, the expression levels of CD31+/CD42b-EMPs, CD105+/CD54+EMPs and vWF in those in the CALs group at the acute and subacute stages were significantly higher than those in the NCALs group (P<0.05). Furthermore, receiver operating characteristic (ROC) curve analysis revealed that the area under the curve (AUC) of CD31+/CD42b-EMPs combined with vWF was 0.896, which indicates a higher diagnostic value in predicting CALs in children with KD. Conclusions:In our study, expression levels of EMPs and vWFare expected to used for early diagnosis, and which are associated with coronary artery injury in KD.

Abstract The most common gynecologic cancers detected in women in Turkey are uterine cancer, ovarian cancer, and cervical cancer. These data reported that a mean of 3800 individuals were diagnosed with uterine cancer, 2790 were diagnosed with ovarian cancer, and 1950 were diagnosed with cervical cancer, and 400 individuals were diagnosed with other gynecologic cancers each year in Turkey. A mean of 14.270 individuals were detected to have been diagnosed with gynecologic cancers each year in the United States of America(USA). Ovarian cancer treatment is generally composed of chemotherapy, and surgery. In general, chemotherapy is administered after surgery. The identification of the molecular pathogenesis of ovarian cancer, and discovery of new moleculer biomarkers which facilitate the ovarian cancer treatment are required for an effective ovarian cancer treatment in clinics. miRNAs are reported to be the possible biologic indicators for various cancer types. We aimed to investigate 2 miRNAs which were suggested to have effect in ovarian cancer in our (previous)monozygotic twin study from miR-1260 microRNA family whose association with ovarian cancer yet has not been reported in the literature. We investigated the expression levels of miR-1260a, and miR-1260b miRNAs, in the peripheral blood lymphocytes of 150 familial and sporadic ovarian cancer patients, and of 100 healthy individuals of the control group who were matched for age, sex, and ethnicity with the patient group, and investigated their possible property of being a biologic indicator for ovarian cancer. The expression results of ovarian cancer patients were evaluated by comparison of the results of the control group in the study. The expression levels of miR-1260a, and miR-1260b in ovarian cancer patients were found highly increased compared with the levels in the control group. miR-1260a expression level in ovarian cancer patients was detected to have increased approximately 17 fold compared with the control group, and miR-1260b expression level in ovarian cancer patients was detected to have increased approximately 33 fold compared with the levels in the control group. The String Analyses showed that the miR-1260a was associated with the ribosomal protein family which was known to be effective in the translation stage of cell and that miR-1260b was associated with CHEK2 protein which was a member of the serine/threonine-protein kinase family. It should be investigated for larger cohorts in benign ovarian diseases and in different stages of patients receiving ovarian cancer treatment whether these two molecules are a noninvasive biomarker and therapeutic target to be used especially in the early diagnosis and prognosis of ovarian cancer in future.

AbstractThe purpose of the present study was to evaluate the diagnostic role of CRP in ovarian cancer and to assess whether CRP can be combined with tumor markers to enhance the diagnostic efficacy toward ovarian cancer. Area under the curve, sensitivity, and specificity were calculated to access the diagnostic ability of each singly and combined as markers for ovarian cancer. The CRP cut-off value was then calculated to evaluate the diagnostic efficacy of CRP for ovarian cancer. Our results showed that values for all markers were significantly higher in the cancer group than in the control group. Receiver operating characteristic curve results showed that CA125 had the highest diagnostic efficacy for ovarian cancer, while the sensitivity for CRP was higher than for CA125, and the specificity for CRP was equal to that of CA125. The combination of CRP, CA125, and HE4, however, provided the strongest diagnostic capability. Furthermore, the diagnostic cut-off value for CRP with regard to ovarian cancer was 9.8 mg/L, and high levels of CRP were correlated with stage and tumor size of ovarian cancer. Our study indicated that CRP is valuable in the diagnosis of ovarian cancer, and that combining CRP with CA125 and HE4 improved the diagnostic efficacy with respect to ovarian cancer.

Diagnostic Efficacy

Introduction: Sepsis remains a major cause of death in critically ill patients in Indian population because of high susceptibility towards infectious diseases in the world. Procalcitonin (PCT) is a well-studied marker in foreign countries but needs to be established in Indian population. In the last few years, importance of Arginase as a marker of immunity has also increased exceptionally, because this enzyme is essentially involved in different inflammatory processes. Keeping these facts in mind PCT and Arginase were evaluated for their utility as markers to diagnose sepsis. Aim: To evaluate Arginase and PCT as biomarkers for early diagnosis of sepsis. Materials and Methods: Hundred adult patients (age >18 years) with Systemic Inflammatory Response Syndrome (SIRS) attending BJ Medical College which is affiliated with Sassoon General Hospital (Pune, Maharashtra, India) during May 2012-July 2015 were incorporated in the study. Age n sex-matched of 100 samples healthy controls were also collected. Arginase was estimated by Roman and Ray method and PCT by Enzyme-linked Immunosorbent Assay Kit (ELISA) method. Unpaired t-test was done to compare the mean biomarker levels between the cases and controls. The Area Under Curve (AUC) was calculated using Receiver Operating Curve (ROC). All the data analysis was set at 95% Confidence Interval (CI) and value p<0.05 are statistically significant. Data analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0. Results: In the study, a significant increase was observed in the levels of arginase (p<0.01) and PCT (p<0.01) in cases as compared to controls. ROC curves were plotted to find out the cut-offs of arginase (4.6 IU/L) and PCT (0.04 ng/mL) to check the diagnostic efficacy of both the biomarkers. Conclusion: Serum PCT and arginase offers a high level of accuracy than other currently available tests and hence can be helpful in the management of sepsis. In addition to this apart from high sensitivity and specificity arginase estimation is cost effective as compared to PCT.

Background. Allergic rhinitis (AR) is an inflammatory state categorized by a disturbance of immunoregulatory mechanisms. MicroRNA-155 (miRNA-155) has an essential role in regulating gene expression and can mediate the allergic TH2 process. Objective. In this study, we aimed to evaluate the role of miR-155 as a biomarker in AR and correlate its level with the total nasal symptom score (TNSS) and the levels of serum interleukin-4 (IL-4). Methods. This study included 90 children: 45 with pollen-induced AR and 45 healthy controls. Serum miR-155 expression levels were measured using quantitative real-time PCR. Human IL-4 ELIZA kits were used for the semiquantitative detection of the serum levels of IL-4. Receiver operating characteristic (ROC) curves were used to determine the best cutoff values for the studied parameters for the diagnosis of AR. Results. The demographic characteristics of the two groups were matched with respect to age and sex. The AR case group included 23 (51.1%) males and 22 (48.9%) females, while the control group included 24 (53.3%) males and 21 (46.7%) females. The miR-155 level was increased in the serum of children with pollen-induced AR compared with controls (mean difference = 2.8, p < 0.001 ). A significant positive correlation between the serum expression level of miR-155 and TNSS in children with AR was detected (r = 0.494, p < 0.001 ). However, no significant correlation was identified between the expression of miR-155 and that of IL-4. At a cutoff value of 1.09, the sensitivity of miR-155 as a biomarker for AR was 100%, and the specificity was 71.1%. Conclusion. MiR-155 expression levels were elevated in the serum of AR children. Therefore, miR-155 could be used as a biomarker in AR diagnosis.
