en The Emerging Role of Circular RNA Homeodomain Interacting Protein Kinase 3 and Circular RNA 0046367 through Wnt/Beta-Catenin Pathway on the Pathogenesis of Nonalcoholic Steatohepatitis in Egyptian Patients زیست شناسی ملکولی Molecular Biology مقالات اصلی Original Article <div style="text-align: justify;">Background: Non-alcoholic fatty liver disease is a major problem worldwide that needs non-invasive biomarkers for early diagnosis and treatment response assessment. We aimed to assess the correlation between circRNA-HIPK3 and miRNA-29a expression and its role as miRNA-29a sponge, as well as the correlation between circRNA-0046367 and miRNA-34a expression and its role as miRNA-34a sponge and their effect on regulation of the Wnt/β catenin pathway, which may provide a new target for treatment of non-alcoholic steatohepatitis. </div> <div style="text-align: justify;">Methods: the research was performed on 110 participants: group (I): fifty-five healthy donors served as controls and group (II): fifty-five patients with fatty liver pattern on abdominal ultrasound. Lipid profile and liver functions were assessed. RT-PCR was performed to assess the RNAs: circRNA-HIPK3, circRNA-0046367, miRNA-29a, miRNA-34a and Wnt mRNA gene expression. ELISA was performed to determine β-catenin protein levels. Results: miRNA-34a and circRNA-HIPK3 expression were significantly greater, while miRNA-29a and circRNA-0046367 expression were significantly less, in patients than in controls. Wnt/β-catenin regulated by miRNA-29a and miRNA-34a showed a significant decrease that leads to its abnormal effect on lipid metabolism. Conclusions: our results imply that miRNA-29a can be investigated as a target for circRNA-HIPK3, while miRNA-34a can be investigated as a target for circRNA-0046367, and that circRNA-HIPK3 and circRNA-0046367 may have emerging roles that can affect the pathogenesis of nonalcoholic steatohepatitis through the Wnt/β-catenin pathway and thus be used as therapeutic targets for the disease.</div> Circrna-HIPK3, circRNA-0046367, miRNA-29a, miRNA-34a, Wnt/β-catenin NASH. 614 625 http://rbmb.net/browse.php?a_code=A-10-1148-1&slc_lang=en&sid=1 Marwa Abdelgwad 100319475328460016810 100319475328460016810 No Medical Biochemistry and Molecular Biology Department, Faculty of Medicine, Cairo University, Egypt.
