Background: Acute appendicitis (AA) is a momentous, emergency, surgical pathology that has still been investigated for both etiopathogenetic unknowns and challenges in diagnosis. Presently, there is little information about the role of microRNAs (miRNAs), which have basic biological functions in the cell, can be a marker, and are associated with various pathologies, in patients with AA. The aim of this study was to investigate the expressions of some miRNAs in AA.
Methods: Overall, 41 miRNAs were screened in 48 individuals comprising 24 patients with AA and 24 healthy controls at Erciyes University Genome and Stem Cell Center (GENKOK). The obtained data were analyzed using appropriate statistical methods.
Results: miR-29c-3p was found to be increased 2-fold during the first 4-6 h in AA, and this increase was revealed to be statistically significant compared with healthy individuals. Similarly, expressions of let-7b-5p, let-7i-5p, miR-30a-5p, miR-29b-3p, and miR-23a-3p also increased approximately 2-fold in AA, although not statistically significant. No significant differences were found in the screening of the remaining 35 miRNAs in patients with AA.
Conclusion: Although there is little information about the relationship between AA and miRNAs currently, miR-29c-3p was reported to increase in the acute period of AA in this study. With the current results, it can be argued that miR-29c-3p bears the potential to be a marker in patients with AA. The present study may also be a basic research for more extensive and necessary miRNAs screening in this field.
