Male Sprague-Dawley rats (n = 36, 250\u2013300 g) were equally divided into 3 groups: sham, tIRI, and tIRI + NQDI-1 (10 mg\/kg, i.p, pre-reperfusion). For tIRI induction, the testicular cord and artery were occluded for 1 h followed by 4 h of reperfusion. Histological analyses, protein immunoexpression, biochemical assays, and real-time PCR were used to evaluate spermatogenesis, ASK-1\/Trx axis expression, enzyme activities, and relative mRNA expression, respectively. During tIRI, ipsilateral testes underwent oxidative stress indicated by low levels of superoxide dismutase (SOD) and Glutathione (GSH), increased oxidative damage to lipids and DNA, and spermatogenic damage. This was associated with induced mRNA expression of pro-apoptosis genes, downregulation of antiapoptosis genes, increased caspase 3 activity and activation of the ASK-1\/JNK\/p38\/survivin apoptosis pathway. In parallel, the expression of Trx, Trx reductase were significantly reduced, while the expression of Trx interacting protein (TXNIP) and the NADP+\/ nicotinamide Adenine Dinucleotide phosphate (NADPH) ratio were increased. These modulations were attenuated by NQDI-1 treatment. In conclusion, the Trx system is regulated by the ASK-1\/Trx\/TXNIP axis to maintain cellular redox homeostasis and is linked to tIRI-induced germ cell apoptosis via the ASK-1\/JNK\/p38\/survivin apoptosis pathway.<\/jats:p>","DOI":"10.3390\/molecules24183333","type":"journal-article","created":{"date-parts":[[2019,9,12]],"date-time":"2019-09-12T10:56:06Z","timestamp":1568285766000},"page":"3333","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["The Thioredoxin System is Regulated by the ASK-1\/JNK\/p38\/Survivin Pathway During Germ Cell Apoptosis"],"prefix":"10.3390","volume":"24","author":[{"given":"Nora","family":"Al-Kandari","sequence":"first","affiliation":[{"name":"Department of Biochemistry, Faculty of Medicine, Kuwait University, Jabriyah 13110, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatemah","family":"Fadel","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Medicine, Kuwait University, Jabriyah 13110, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farah","family":"Al-Saleh","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Medicine, Kuwait University, Jabriyah 13110, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farah","family":"Khashab","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Medicine, Kuwait University, Jabriyah 13110, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"May","family":"Al-Maghrebi","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Medicine, Kuwait University, Jabriyah 13110, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,12]]},"reference":[{"key":"ref_1","first-page":"835","article-title":"Testicular torsion: Diagnosis, evaluation, and management","volume":"88","author":"Sharp","year":"2013","journal-title":"Am.
