Upregulated miRNAs such as ssc-miR-23a, ssc-miR-29c, ssc-miR-193a-3p, and ssc-miR-574-3p may serve as potential candidates for IUGR testes and are predicted to target core genes including YWHAZ, YWHAB, and PPP2CA, potentially acting synergistically to suppress cell cycle progression and promote apoptosis. This evidence concerns the gene PPP2CA and fetal growth restriction.
