Quercetin (Que) is a flavonoid compound with antioxidant and other biological activities. To investigate the protective effect of Que on Cd-induced renal apoptosis in rats. 24 male SD rats were randomly divided into four groups. They were treated as follows: control group was administered orally with normal saline (10\u00a0ml\/kg); Cd group was injected with 2\u00a0mg\/kg CdCl\n                    <jats:sub>2<\/jats:sub>\n                    intraperitoneally; Cd + Que group was injected with 2\u00a0mg\/kg CdCl\n                    <jats:sub>2<\/jats:sub>\n                    and intragastric administration of Que (100\u00a0mg\/kg); Que group was administered orally with Que (100\u00a0mg\/kg). The experimental results showed that the body weight of Cd-exposed rats significantly decreased and the kidney coefficient increased. In addition, Cd significantly increased the contents of Blood Urea Nitrogen, Creatinine and Uric acid. Cd also increased the glutathione and malondialdehyde contents in renal tissues. The pathological section showed that Cd can cause pathological damages such as narrow lumen and renal interstitial congestion. Cd-induced apoptosis of kidney, which could activate the mRNA and protein expression levels of Cyt-c, Caspase-9 and Caspase-3 were significantly increased. Conversely, Que significantly reduces kidney damage caused by Cd. Kidney pathological damage was alleviated by Que. Que inhibited Cd-induced apoptosis and decreased Cyt-c, Caspase-9 and Caspase-3 proteins and mRNA expression levels. To sum up, Cd can induce kidney injury and apoptosis of renal cells, while Que can reduce Cd-induced kidney damage by reducing oxidative stress and inhibiting apoptosis. These results provide a theoretical basis for the clinical application of Que in the prevention and treatment of cadmium poisoning.\n                  <\/jats:p>","DOI":"10.3389\/fphar.2022.990993","type":"journal-article","created":{"date-parts":[[2022,8,16]],"date-time":"2022-08-16T03:47:36Z","timestamp":1660621656000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":28,"title":["Protective effect of quercetin on cadmium-induced renal apoptosis through cyt-c\/caspase-9\/caspase-3 signaling pathway"],"prefix":"10.3389","volume":"13","author":[{"given":"Ruxue","family":"Huang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lulu","family":"Ding","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Ye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ke","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjing","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bingzhao","family":"Yan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zongping","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jicang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,8,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"280","DOI":"10.1161\/CIRCRESAHA.119.316306","article-title":"Role of mitochondrial calcium and the permeability transition pore in regulating cell death","volume":"126","author":"Bauer","year":"2020","journal-title":"Circ.
