  • 简介:AbstractBackground:Circular RNA (circRNA) is a type of closed circular noncoding RNA (ncRNA), mostly formed by back-splicing or alternative splicing of pre-messenger RNA (mRNA). The aim of this study was to explore the expression profile of circRNA in peripheral blood mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS) and discover potential molecular markers of AS.Methods:The circRNA microarray technology was used to detect the expression of circRNAs in the peripheral blood of 6 patients with AS and 6 healthy controls (HC). To screen the differentially expressed circRNAs by fold change (FC) and P value, these differentially expressed circRNAs were analyzed by bioinformatics. In 60 cases of AS and 30 cases of HC, 4 circRNAs were subjected to real-time fluorescence quantitative polymerase chain reaction (RT-qPCR), and their correlation with various clinical indicators was analyzed. Finally, the receiver operating characteristic (ROC) curve was used to analyze their potential as AS diagnostic markers.Results:The microarray results showed that there were 1369 significantly differently expressed (P < 0.05, FC > 1.5) circRNAs between the AS and HC groups (675 upregulated and 694 downregulated). The results of bioinformatics analysis suggested that they were mainly involved in "enzyme binding," "adenosine ribonucleotide binding," "MAPK signaling pathway" , etc. The RT-qPCR results showed that the expressions of hsa_circRNA_001544 (U = 486.5, P < 0.05) and hsa_circRNA_102532 (U = 645, P < 0.05) were significantly different between the AS group and the HC group. The AS group was further divided into two subgroups: active AS (ASA) and stable AS (ASS). After analysis, it was found that compared with the HC group, hsa_circRNA_001544 was significantly increased in both ASA (U = 214, P < 0.05) and ASS groups (U = 273, P < 0.05), while hsa_circRNA_008961 (U = 250, P < 0.05) and hsa_circRNA_102532 (U = 295, P < 0.05) were only significantly increased in the ASA group. Furthermore, hsa_circRNA_012732 was significantly different between the ASA and ASS groups (U = 194, P < 0.05), and there was no statistical significance among the remaining groups. Correlation analysis results showed that hsa_circRNA_012732 was negatively correlated with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), high-sensitivity C-reactive protein (hsCRP), and globulin (GLOB) and positively correlated with lymphocyte count (LY), mean corpusular volume, and albumin (ALB), and hsa_circRNA_008961 was negatively correlated with platelet (PLT) count. ROC curve analysis showed that hsa_circRNA_001544 (95% CI = 0.610-0.831, P < 0.05) and hsa_circRNA_102532 (95% CI = 0.521-0.762, P < 0.05) were statistically significant, and their area under curve (AUC) values were 0.720 and 0.642, respectively.Conclusions:There are differentially expressed circRNAs in PBMCs of AS patients, and they may be involved in the occurrence and development of AS. Among these differentially expressed circRNAs, hsa_circRNA_012732 has the potential to become an indicator of disease activity, and hsa_circRNA_001544 has the potential to become a molecular marker for AS diagnosis.

  • 简介:AbstractBackground:The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor, which is critically involved in the pathogenesis of a variety of skin diseases. The aim of this study was to detect AhR and its downstream regulators including cytochrome P450 (CYP1A1), AhR nuclear translocation (ARNT), and aryl hydrocarbon receptor repressor (AhRR) in serum, peripheral blood mononuclear cells (PBMCs), and skin lesions in patients with atopic dermatitis (AD).Methods:Twenty-nine AD patients defined according to the criteria of Hanifin and Rajka and Chinese criteria of AD were included. Subjects without allergic and chronic diseases were recruited as controls. Patients and controls were selected from the dermatology outpatient clinic of Peking University People’s Hospital from August 1 to December 31 in 2018. Enzyme-linked immunosorbent assay was performed to detect serum AhR level. The mRNA of AhR, AhRR, ARNT, and CYP1A1 in PBMCs were measured by realtime quantitative polymerase chain reaction. AhR expression in skin lesions was measured by immunohistochemistry.Results:AhR was significantly higher expressed in serum (41.26 ± 4.52 vs. 33.73 ± 2.49 pmol/L, t = 6.507, P < 0.001) and skin lesions (0.191 ± 0.041 vs. 0.087 ± 0.017, t = 10.036, P < 0.001) of AD patients compared with those of controls. The mRNA levels of AhR (1.572 ± 0.392 vs. 1.000 ± 0.173, t= 6.819, P < 0.001), AhRR (2.402 ± 1.716 vs. 1.000 ± 0.788, t= 3.722, P < 0.001), CYP1A1 (2.258 ± 1.598 vs. 1.000 ± 0.796, t= 3.400, P = 0.002) in PBMCs of AD patients were higher compared with those of controls. The difference in mRNA levels of ARNT was not statistically significant between the patients and controls (1.383 ± 0.842 vs. 1.000 ± 0.586, t= 1.653, P = 0.105). AhR mRNA levels in PBMCs positively correlated with eczema area and severity index score and serum interleukin-6 levels.Conclusion:AhR and its downstream regulators were highly expressed in serum, PBMCs, and skin of AD patients, which might contribute to the pathogenesis of AD.

  • 简介:AbstractObjective:This article aimed to compare the peripheral blood flow intensity (BFI) in the maternal right and left kidney in uncomplicated third trimester pregnancies and to study possible associations between parenchymal BFI in the kidneys and maternal, labor and new-born characteristics.Methods:We conducted a prospective cohort study in third trimester pregnancies at Trondheim University Hospital, Norway, from January to April 2018. The BFI in the maternal kidneys was examined with color Doppler ultrasound and the peripheral BFI was calculated using the Pixel Flux-method which is a method based on pixel wise calculation of color in an image. Velocity was coded by the color bar in the ultrasound device. The peripheral BFI was calculated as the product of velocity and area encoded by all colored pixels divided by all pixels within the cortical layer by a software examining the color in each pixel of a standardized region of interest of the renal parenchyma in video-clips through a complete heart cycle. BFI (cm/s) was thus calculated as follows:The primary outcome measure was peripheral BFI in the renal cortex. We also examined associations between BFI in the entire cortex with maternal age, body mass index, blood pressure, pH in the umbilical artery, Apgar score after 5 minutes and birthweight.Results:In all, 51 pregnant women were included in the study, but 17 were excluded, mainly due to movement artifacts from the pulsating aorta, leaving 34 women in the final study population. We found significantly lower BFI in the cortex of the left kidney compared with the right kidney, 0.37 cm/s versus 0.69 cm/s, respectively (P = 0.04). Dividing into regions, the BFI was significantly lower in the proximal 25% of the left renal cortex compared to the corresponding right side (P= 0.01), and in the proximal 50% cortex (P= 0.02), but the differences were not significantly different in the distal 25% (P= 0.06) or in the distal 50% (P= 0.20) of the renal cortex.We observed a significant negative correlation between peripheral BFI in the left kidney and both systolic blood pressure (r = -0.38; P= 0.03) and diastolic blood pressure (r= -0.36; P= 0.04), and no significant correlations between BFI with maternal age, body mass index, blood pressure, pH in the umbilical artery, Apgar score after 5 minutes and birthweight in the left kidney (P > 0.05). We did not observe any significant correlations between BFI in the right kidney and maternal or new-born characteristics (P > 0.05).Conclusion:The BFI in the left renal cortex was lower compared with the right renal cortex, and BFI in the left renal cortex was negatively correlated with blood pressure, but not significantly correlated with maternal age, body mass index or newborn characteristics. We did not observe any significant correlations between BFI in the right kidney and maternal or new-born characteristics.
