Crystal Structures of Human Dipeptidyl Peptidase Ⅳ in its Apo and Diprotin B-complexed Forms

引用

Acta Biochimica et Biophysica Sinica 2007年第5期39卷 335-343页

作者： Hajime H1RAMATSU Kiyoshi KYONO Atsushi YAMAMOTO Kazuhiko SAEKI Hideaki SHIMA Shigeru SUGIYAMA Koji INAKA ryo SHIMIZU Tanabe Seiyaku Co. Ltd Osaka 532-8505 Japan Aphoenix Inc. Tokyo 150-0002 Japan Maruwa Food Industries Inc. Nara 639-1123 Japan Mol Logics Inc. Kyoto 619-0237 Japan Maruwa Food Industries Inc. Nara 639-1123 Japan

Dipeptidyl peptidase Ⅳ (DPPIV), which belongs to the prolyl oligopeptidase family of serine proteases, is known to have a variety of regulatory biological functions and has been shown to be implicated in type 2 diabetes. It is therefore important to develop selective human DPPIV (hDPPIV) inhibitors. In this study, we determined the crystal structure of apo hDPPIV at 1.9 A resolution. Our high-resolution crystal structure of apo hDPPIV revealed the presence of sodium ion and glycerol molecules at the active site. In order to elucidate the hDPPIV binding mode and substrate specificity, we determined the crystal structure of hDPPIV-diprotin B (Val-Pro-Leu) complex at 2.1 A resolution, and clarified the difference in binding mode between diprotin B and diprotin A (Ile-Pro-Ile) into the active site of hDPPIV. Comparison between our crystal structures and the reported apo hDPPIV structures revealed that positively charged functional groups and conserved water molecules contributed to the interaction of ligands with hDPPIV. These results are useful for the design of potent hDPPIV inhibitors.

Cyberknife treatment for advanced or terminal stage hepatocellular carcinoma

AIM: To investigate the safety and efficacy of the Cyberknife treatment for patients with advanced or terminal stage hepatocellular carcinoma(HCC).METHODS: Patients with HCC with extrahepatic metastasis or vascular or bile duct invasion were enrolled between May 2011 and June 2015. The Cyberknife was used to treat each lesion. Treatment response scores were based on Response Evaluation Criteria in Solid Tumors v1.1. The trends of tumor markers,including alpha fetoprotein(AFP) and proteins induced by vitamin K absence Ⅱ(PIVKA Ⅱ) were assessed. Prognostic factors for tumor response and tumor markers were evaluated with Fisher's exact test and a logistic regression model. Survival was evaluated with the Kaplan-Meier method and multivariate analysis was performed using the Cox proportional hazards ***: Sixty-five patients with 95 lesions were enrolled. Based on the Barcelona Clinic Liver Cancer classification,all patients were either in the advanced or terminal stage of the disease. The target lesions were as follows: 52 were bone metastasis; 9,lung metastasis; 7,brain metastasis; 9,portal vein invasion;4,hepatic vein invasion; 4,bile duct invasion; and 10 other lesion types. The response rate and disease control rate were 34% and 53%,respectively. None of the clinical factors correlated significantly with tumor response. Fiducial marker implantation was associated with better control of both AFP(HR = 0.152; 95%CI: 0.026-0.887; P = 0.036) and PIVKA Ⅱ(HR = 0.035; 95%CI: 0.003-0.342; P = 0.004). The median survival time was 9 mo(95%CI: 5-15 mo). Terminal stage disease(HR = 9.809; 95%CI: 2.589-37.17,P < 0.001) and an AFP of more than 400 ng/m L(HR = 2.548; 95%CI: 1.070-6.068,P = 0.035) were associated with worse survival. A radiation dose higher than 30 Gy(HR = 0.274; 95%CI: 0.093-0.7541,P = 0.012) was associated with better survival. In the 52 cases of bone metastasis,36 patients(69%) achieved pain relief. One patient had cerebral bleeding and another patient ha
