en The Ratio of Cysteine-Rich Angiogenic Inducer 61 to MicroRNA -155 Expression as a Preeclampsia Diagnostic Marker and Predictor of Its Severity بیوشیمی Biochemistry مقالات اصلی Original Article <div style="text-align: justify;">Background: Preeclampsia (PE) is a multisystem pregnancy disorder that increases maternal-perinatal morbidity and mortality significantly. MicroRNA-155 (miR-155) overexpression in the sera of pregnant women has been linked to preeclampsia. Researchers discovered that miR-155 acts during pregnancy by down-regulating and reducing the cysteine-rich angiogenic inducer 61 (CYR61), which causes local ischemia as well as oxidative stress. Methods: The level of miR-155 expression in all serum samples was quantified using real-time polymerase chain reaction (RT-PCR), and serum CYR61 was measured using enzyme-linked immunosorbent assays. Together with the Cyr-61/miR-155 ratio, they were evaluated as biomarkers for PE pathogenesis and severity prediction. Results: MiR-155 expression, serum CYR61 levels, and Cyr-61/miR-155 ratios were all significantly higher in PE patients compared to the control group. Serum CYR61 levels and the Cyr-61/miR-155 ratio differed significantly between mild and severe PE patients. Conclusion: MiR-155 expression, serum CYR61 levels, and Cyr-61/miR-155 may serve as biomarkers for PE pathogenesis and severity prediction.</div> <quillbot-extension-portal></quillbot-extension-portal><quillbot-extension-portal></quillbot-extension-portal><quillbot-extension-portal></quillbot-extension-portal> Biomarker, Cysteine-Rich Protein 61, MicroRNAs, Pre-Eclampsia. 332 339 http://rbmb.net/browse.php?a_code=A-10-1249-1&slc_lang=en&sid=1 Sarah Mamdouh Shoeib 100319475328460017978 100319475328460017978 No Clinical pathology department, Faculty of Medicine, Tanta University, Egypt.
