Cryptorchidism was established surgically in Kunming mice, which were then treated with 20\u00a0\u00b5g g\u20131 day\u20131, s.c., RSV for 35 consecutive days. Typical manifestations of spermatogenesis arrest were seen in mice with cryptorchidism, and RSV treatment for 35 days restored spermatogenesis. Liquid chromatography\u2013tandem mass spectrometry was used to profile the metabolome of testes from mice in the control (non-cryptorchid, untreated), cryptorchid and RSV-treated cryptorchid groups. In all, 1386 and 179 differential metabolites were detected in the positive and negative modes respectively. Seven and six potential biomarkers were screened for spermatogenesis arrest and restoration respectively. Pathway analysis showed changes in 197 metabolic pathways. The hexosamine biosynthesis pathway was inhibited in the cryptorchid group, which probably resulted in a decrease in the end product, uridine diphosphate N-acetylglucosamine (UDP-GlcNAc). Immunoblot analysis showed that total testicular protein O-linked \u03b2-N-acetylglucosamine glycosylation was related to spermatogenesis arrest, further indicating a decrease in UDP-GlcNAc in the cryptorchid group. Thus, untargeted metabolomics revealed the biochemical pathways associated with the restoration of metabolic status in the cryptorchid group following RSV treatment and the findings could be used to monitor the response to RSV treatment. This study provides a meaningful foundation for the future clinical application of RSV in the treatment of spermatogenesis dysfunction.<\/jats:p>","DOI":"10.1071\/rd20189","type":"journal-article","created":{"date-parts":[[2021,2,18]],"date-time":"2021-02-18T21:30:04Z","timestamp":1613683804000},"page":"328-337","source":"Crossref","is-referenced-by-count":4,"title":["Metabolomics analysis reveals metabolic changes associated with trans-resveratrol treatment in experimental cryptorchidism mice"],"prefix":"10.1071","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4184-7972","authenticated-orcid":true,"given":"Siqiang","family":"Li","sequence":"first","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun","family":"Li","sequence":"additional","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."},{"name":"BZhumadian Academy of Industry Innovation and Development, Huanghuai University, Zhumadian, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fujia","family":"Chen","sequence":"additional","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yurong","family":"Yang","sequence":"additional","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Song","sequence":"additional","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chaoying","family":"Liu","sequence":"additional","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."},{"name":"BZhumadian Academy of Industry Innovation and Development, Huanghuai University, Zhumadian, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baogen","family":"Wang","sequence":"additional","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanhong","family":"Xu","sequence":"additional","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingguang","family":"Shao","sequence":"additional","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7014-282X","authenticated-orcid":true,"given":"Enzhong","family":"Li","sequence":"additional","affiliation":[{"name":"ASchool of Biological and Food Processing Engineering, Huanghuai University, Zhumadian, China."},{"name":"CCorresponding author.
