Abstrakt: microRNAs (miRNAs) have a serious and dynamic function in spermatogenesis. These molecules have been recognized as crucial parts of the control of gene activity, and their involvement in the regulation of target genes has been extensively studied. This research aimed to determine the expression of CRISP3 and miR-493-5p, miR-204-5p, and miR-182-5p in the seminal plasma fluid and spermatozoa and to examine the relationship between CRISP3 and the mentioned miRNAs in 57 infertile men with Asthenozoospermia (AZ) (n = 19), Teratoasthenozoospermia (TAZ) (n = 19), and Normozoospermia (NZ) (n = 19). The selection of these three miRNAs, miR-493-5p, miR-204-5p, and miR-182-5p, was conducted using computational prediction algorithms. These miRNAs were nominated as CRISP3-associated miRNAs that can target CRISP3. We performed the quantitative real-time polymerase chain reaction (qRT-PCR) method to determine the levels of the studied miRNA expression. In the following stage, the expression of two protein isoforms of CRISP3, targeted by these miRNAs, was quantified using western blotting. The results demonstrate significant differences in the levels of miR-182-5p, miR-204-5p, miR-493-5p, and CRISP3 isoforms among the patient groups. In TAZ individuals, miR-182-5p and miR-204-5p expression decreased, while miR-493-5p expression increased compared to the control samples. Additionally, significant differences were observed in the expression levels of unglycosylated and glycosylated CRISP3 isoforms between the AZ and NZ groups. Correlation analysis revealed associations between miRNA expression and the expression of CRISP3 isoforms in the patient groups. Additionally, there were correlations between the expression of CRISP3 isoforms and sperm motility and morphology. These results offer valuable insights into the underlying molecular processes associated with male infertility.
