| 1 | Lipopolysaccharide/Toll-like receptor 4 signaling pathway involved Qingdu decoction treating severe liver injury merging with endotoxemia显示文摘OBJECTIVE: To investigate the protective effects and underlying mechanism of Qingdu decoction(QDD) on experimental rats with severe liver injury induced by thioacetamide(TAA).METHODS: A total of 40 Wistar rats were randomly divided into normal group(n = 10) and experimental group(n = 30). Rats were administrated the same content of saline in normal group. The rats inthe experimental group were pretreated with TAA at dose of 12 mg/kg lasting 8 weeks, and from 9th week to 12 th week, with TAA at concentration of 36mg/kg. During the 9th week to 12 th week period,the rats were randomly divided into three subgroups(n = 10 each) simultaneously based on the treatment categories: model group, lactulose(LA,3.5 m L/kg) group and QDD(5.95 g/kg) group, orally once per day respectively. At the 12 th week, the content of serum alanine transaminase(ALT), aspartate transaminase(AST), total bilirubin(TBIL), endotoxin(ET) and tumor necrosis factor α(TNF-α) was detected by automatic biochemical analyzer. The plasma prothrombin time(PT), prothrombin time-international normalized ratio(PTR) and prothrombin time activity(PTA) were measured by automatic coagulation analyzer. The level of lipopolysaccharide(LPS)-binding protein(LBP), cluster differentiation 14(CD14) and Toll-like receptor 4(TLR4) expressions was measured by both western blot(WB) and real-time polymerase chain reaction(real-time PCR).RESULTS: Compared with the model group, hepatic morphology in the QDD group was improved under light microscope and transmission electron microscope; at the same time, the contents of serum ALT, AST, TBIL, ET and TNF-α, and level of LBP, CD14 and TLR4 expressions in liver tissues were significantly decreased compared with the model group(P < 0.05), while PTA in the QDD group was enhanced(P < 0.05).CONCLUSION: QDD has the functional effect on improving the injured liver through inhibiting the LPS/TLR4 signaling pathway thus decreasing the level of the inflammatory medicators. | Cao Wubing Du Yuqiong Gao Lianyin Che Niancong Zhang Qiuyun Fu Xiuwen Luo Jiajia Wang Rongbing | 2017 | Journal of Traditional Chinese Medicine2017，37，3： | 0 |
| 2 | Machine Learning Modeling of Protein-intrinsic Features Predicts Tractability of Targeted Protein Degradation显示文摘Targeted protein degradation(TPD)has rapidly emerged as a therapeutic modality to eliminate previously undruggable proteins by repurposing the cell’s endogenous protein degradation machinery.However,the susceptibility of proteins for targeting by TPD approaches,termed“degradability”,is largely unknown.Here,we developed a machine learning model,model-free analysis of protein degradability(MAPD),to predict degradability from features intrinsic to protein targets.MAPD shows accurate performance in predicting kinases that are degradable by TPD compounds[with an area under the precision–recall curve(AUPRC)of 0.759 and an area under the receiver operating characteristic curve(AUROC)of 0.775]and is likely generalizable to independent non-kinase proteins.We found five features with statistical significance to achieve optimal prediction,with ubiquitination potential being the most predictive.By structural modeling,we found that E2-accessible ubiquitination sites,but not lysine residues in general,are particularly associated with kinase degradability.Finally,we extended MAPD predictions to the entire proteome to find964 disease-causing proteins(including proteins encoded by 278 cancer genes)that may be tractable to TPD drug development. | Wubing Zhang Shourya S.Roy Burman Jiaye Chen Katherine A.Donovan Yang Cao Chelsea Shu Boning Zhang Zexian Zeng Shengqing Gu Yi Zhang Dian Li Eric S.Fischer Collin Tokheim X.Shirley Liu | 2022 | Genomics, Proteomics & Bioinformatics2022，20，5： | 0 |
