However, there is no evidence showing that it helps to prevent diabetic nephropathy (DN). We used a high glucose (HG)-induced HK-2 cell model and a streptozocin (STZ)-induced Wistar rat model to investigate the effects of TKL on DN, as well as the mechanisms for those effects. Our results showed that TKL significantly increased the viability of HG-treated HK-2 cells and inhibited cell apoptosis. In vivo experiments demonstrated that TKL attenuated STZ-induced histopathological damage and the inflammatory response in rat kidney tissues. Pre-treatment of HK-2 cells or STZ-treated rats with polyinosinic acid (Poly IC), an inhibitor of lectin-like oxLDL receptor 1 (LOX1), blocked the protective effect of TKL against HG- or STZ-induced damage to kidney tissue, indicating that TKL might exert its effect via LOX1-mediated endocytosis. Additional results suggested that TKL inhibits the phosphorylation of I\u03baB kinase \u03b2 (IKK\u03b2) and the nuclear factor-\u03baB (NF-\u03baB) inhibitor protein (I\u03baB\u03b1), and thereby reduces the nuclear translocation of NF-\u03baB (p65). ChIP assay data indicated that TKL markedly inhibits the binding of p65 to the CASP9 gene in HG-treated HK-2 cells, subsequently suppressing transcription of the CASP9 gene. In the dual-luciferase reporter assay, TKL significantly inhibited luciferase activity in cells co-transfected with p65 and a wild-type capase-9 construct instead of mutated caspase-9 constructs.<\/jats:p>\n               <jats:p>Taken together, our results show that TKL helps to protect against DN by inhibiting the LOX1\/NF-\u03baB\/caspase-9 signaling pathway, suggesting TKL as a promising agent for treating DN.<\/jats:p>","DOI":"10.1042\/bsr20180071","type":"journal-article","created":{"date-parts":[[2018,7,23]],"date-time":"2018-07-23T16:25:15Z","timestamp":1532363115000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["<i>Trichosanthes kirilowii<\/i> lectin alleviates diabetic nephropathy by inhibiting the LOX1\/NF-\u03baB\/caspase-9 signaling pathway"],"prefix":"10.1042","volume":"38","author":[{"given":"Jiandong","family":"Lu","sequence":"first","affiliation":[{"name":"Department of Nephrology, Shenzhen Traditional Chinese Medicine Hospital, Guangzhou University of Chinese Medicine, Shenzhen, Guangdong 518033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinting","family":"Peng","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Shenzhen Traditional Chinese Medicine Hospital, Guangzhou University of Chinese Medicine, Shenzhen, Guangdong 518033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Xiang","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Shenzhen Traditional Chinese Medicine Hospital, Guangzhou University of Chinese Medicine, Shenzhen, Guangdong 518033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liangping","family":"He","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Shenzhen Traditional Chinese Medicine Hospital, Guangzhou University of Chinese Medicine, Shenzhen, Guangdong 518033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongcai","family":"Wang","sequence":"additional","affiliation":[{"name":"Centers for Disease Early Treatment, Shenzhen Traditional Chinese Medicine Hospital, Guangzhou University of Chinese Medicine, Shenzhen, Guangdong 518033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guoliang","family":"Xiong","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Shenzhen Traditional Chinese Medicine Hospital, Guangzhou University of Chinese Medicine, Shenzhen, Guangdong 518033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shunmin","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Shenzhen Traditional Chinese Medicine Hospital, Guangzhou University of Chinese Medicine, Shenzhen, Guangdong 518033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2018,9,7]]},"reference":[{"key":"2021111619105701600_B1","doi-asserted-by":"publisher","first-page":"868","DOI":"10.4103\/2230-8210.141388","article-title":"Worldwide burden of diabetes","volume":"18","author":"Bhutani","year":"2014","journal-title":"Indian J.
