Physiol."],"abstract":"<jats:p>In order to improve the glucose utilization capacity of largemouth bass (<jats:italic>Micropterus salmoides<\/jats:italic>), responses to glucose overload between two strains (Y: breeding strain; W: wild strain) were compared at 0, 6, 12, and 24\u00a0h after glucose injection (1.67\u00a0g\/kg). The data revealed that plasma glucose in the Y strain (&amp;lt;12\u00a0h) recovered faster than in the W strain (12\u00a0h), with the Y strain secreted more insulin within 6\u00a0h post-injection. Triglyceride (TG) and low-density lipoprotein-cholesterol (VLDL-CH) content in the Y strain increased, peaking at 12\u00a0h, then decreased, whereas the W strain\u2019s TG content was not affected and VLDL-CH content decreased. The hepatic and muscular fatty acid synthetase, liver x receptor-1, and sterol regulatory element-binding protein expressions were consistent with the TG content change. Both strains\u2019 liver and muscle glycogen contents exhibited similar trends to that of the glycogen synthase gene\u2014increasing, then declining, and peaking at 6 and 12\u00a0h. The expression levels of hepatic and muscular phosphofructokinase and pyruvate kinase in the Y strain increased, peaking at 12\u00a0h. In the W strain, they were suppressed and reached the minimum at 24\u00a0h. The mRNA levels of hepatic and muscular phosphoenolpyruvate carboxykinase and glucose-6-phosphatase were enhanced and peaked at 24\u00a0h in both strains, hepatic isocitrate dehydrogenase-1, and \u03b1-ketoglutarate dehydrogenase complex expression increased after declining, peaking at 12 and 24\u00a0h. Two genes in the W strain\u2019s muscles showed a similar trend. Both strains\u2019 transcriptome results identified seven common functional genes for resistance to hyperglycemia that were involved in the circadian rhythm pathway, which is a suggested key pathway for coping with hyperglycemia. Furthermore, 48 differential genes were identified between the two strains, and these genes were enriched in the TGF-beta and cell cycle signaling pathways, indicating that these pathways may be key factors affecting the differential responses to glucose overload. We conducted a comprehensive comparison of glucose overload molecular responses between two strains of <jats:italic>M. salmoides<\/jats:italic>, and the results can provide a promising strategy to improve the glucose utilization capacity of <jats:italic>M. salmoides<\/jats:italic> based on advantageous pre-existing traits.<\/jats:p>","DOI":"10.3389\/fphys.2022.1010633","type":"journal-article","created":{"date-parts":[[2022,9,28]],"date-time":"2022-09-28T06:26:51Z","timestamp":1664346411000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Different responses to glucose overload between two strains of largemouth bass (Micropterus salmoides)"],"prefix":"10.3389","volume":"13","author":[{"given":"Caixia","family":"Lei","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yujing","family":"Xie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongmei","family":"Song","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinxing","family":"Du","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengjie","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,9,28]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"397","DOI":"10.1111\/j.1749-7345.2008.00168.x","article-title":"Effects of graded levels of carbohydrate on growth and survival of largemouth bass, Micropterus salmoides","volume":"39","author":"Amoah","year":"2008","journal-title":"J.
