“…The octamer-binding transcription factor 4 (Oct4)-cancerous inhibitors of protein phosphatase 2A (CIP2A) axis are considered to be another pathway that increases the antioxidant defense system in spermatic cord torsion/detorsion by activating the Nrf2-HO-1-NQO1 pathway [ 119 ]. Overexpression of the transcription factor Oct4 increases the expression of its downstream gene CIP2A in Leydig, Sertoli, and germ cells, leading to the activation Nrf2 [ 120 ]. Examining microRNAs expression in the testicular tissue of rats with testicular I/R injury shows the upregulated level of miR-101-3p, leading to the downregulation of Nrf2, GST, NQO1, and HO-1 levels.…”
