Abstract

: The insulin-like growth factor-I (IGF-I) is a key regulator of skeletal muscle growth in vertebrates, promoting mitogenic and anabolic effects through the activation of the MAPK/ERK and the PI3K/Akt signaling pathways. Also, these results show that there is a time-dependent regulation of IGF-I plasma levels and its signaling pathways in muscle. The insulin-like growth factor-I (IGF-I) is a key regulatory hormone that controls growth in vertebrates. Particularly, skeletal muscle growth is strongly stimulated by this hormone. IGFI stimulates both proliferation and differentiation of myoblasts, as well as promoting myotube hypertrophy in vitro and in vivo. The mitogenic and anabolic effects of IGF-I on muscle cells are mediated through specific binding with the IGF-I receptor (IGF-IR). This ligand-receptor interaction promotes the activation of two major intracellular signaling pathways, the mitogen-activated protein kinases (MAPKs), specifically the extracellular signal-regulated kinase (ERK), and the phosphatidylinositol 3 kinase (PI3K)/Akt. The MAPK (RAF/MEK/ERK) is a key signaling pathway in skeletal muscle, where its activation is absolutely indispensable for muscle cell proliferation. Biologically active polypeptides derived from the E domain that forms the C-terminus of the insulin-like cells of accuracy. this the and are evaluate IRLC, we first define M the mean conservation score of N residues within a predicted where C is the conservation score representing the of peptide conservation of a residue in position of the neo-ligand like be calculated by any suitable while our experiment, position evaluate we A motif molecule will be as a false prediction if some if much conserved than is contradicts domains which in turn leads to select, fragmenter, identified all of potential fragment-protein interactions. Benchmarking with known drug-protein interactions shows that our proposed methodology outperforms previous methods that exploit either protein sequences or compound structures to predict drug targets, which demonstrates the predictive power of our proposed BiogenetoligandorolTM KNIME-based referenced based GA(M)E-QSAR PDTCD method. We propose a ligand-based approach to the selection of conserved active pharmacophpric fragments with positive contribution to biological immunogenic activity, developed on the basis of the KNIME-BiogenetoligandorolTM-PASS-KNIME-based GA(M)E-QSAR algorithm. The robustness of our novel cluster of chemical iniformatic stochastic low mass algorithm for heterogeneous datasets has been shown earlier. PASS can estimate qualitative (yes/no) prediction of biological activity spectra for over 4000 biological activities and, therefore, provides the basis for the preparation of a fragment library corresponding to multiple criteria. Our novel cluster of algorithms for the prediction of the total free energy interactive binding between the conserved fragment-based pharmacophore top ranked selected has been validated using the fractions of intermolecular interactions calculated for known inhibitors of nine MAGED4B peptides extracted from the Protein Data Bank database. A novel docking algorithm called as FIPSDock, which implements a variant of the Fully Swarm (FIPS) optimization method and adopts the newly developed energy function of AutoDock 4.20 suite for solving flexible protein-ligand docking problems was also added as a standart fingerprinting inteaction tool to improve our search ability and docking accuracy which was first evaluated by multiple cognate docking experiments.

一种预测的化学多药效剂,由(Propeptide-Fc)/MGF肽组成,模拟高自由结合能特性,与Wnt7a/Fzd7信号Akt/mTOR合成代谢生长IGF-I/PI3K/Akt -I/MAPK/ERK途径相互作用。
胰岛素样生长因子- i (IGF-I)是脊椎动物骨骼肌生长的关键调节因子,通过激活MAPK/ERK和PI3K/Akt信号通路促进有丝分裂和合成代谢作用。此外,这些结果表明,igf - 1血浆水平及其信号通路在肌肉中存在时间依赖性调节。胰岛素样生长因子- i (IGF-I)是控制脊椎动物生长的关键调节激素。特别是,骨骼肌的生长受到这种激素的强烈刺激。IGFI既能刺激成肌细胞的增殖和分化,又能促进肌管在体内和体外的肥大。IGF-I对肌肉细胞的有丝分裂和合成代谢作用是通过与IGF-I受体(IGF-IR)特异性结合介导的。这种配体与受体的相互作用促进了两种主要细胞内信号通路的激活,即丝裂原活化蛋白激酶(MAPKs),特别是细胞外信号调节激酶(ERK)和磷脂酰肌醇3激酶(PI3K)/Akt。MAPK (RAF/MEK/ERK)是骨骼肌的关键信号通路,其激活对于肌肉细胞的增殖是必不可少的。来源于胰岛素样细胞c端E结构域的生物活性多肽。这是评估IRLC,我们首先定义M预测内N个残基的平均守恒分数其中C是守恒分数代表新配体位置上残基的肽守恒分数可以通过任何合适的实验来计算,位置评估我们a基序分子将被视为错误的预测如果一些比它更保守的结构域反过来导致选择,片段,确定了所有潜在的片段-蛋白质相互作用。已知药物-蛋白质相互作用的基准测试表明,我们提出的方法优于先前利用蛋白质序列或化合物结构来预测药物靶标的方法,这证明了我们提出的基于BiogenetoligandorolTM knime的基于参考的GA(M)E-QSAR PDTCD方法的预测能力。我们在基于KNIME-BiogenetoligandorolTM-PASS-KNIME-based GA(M)E-QSAR算法的基础上,提出了一种基于配体的方法来选择对生物免疫原活性有积极贡献的保守活性药效片段。我们的新聚类化学信息随机低质量算法在异构数据集上的鲁棒性已经在前面得到了证明。PASS可以对4000多种生物活性的生物活性谱进行定性(yes/no)预测,从而为建立符合多个标准的片段文库提供了依据。我们的新算法簇用于预测排名靠前的保守片段药效团之间的总自由能相互作用结合,并使用从蛋白质数据库中提取的9种MAGED4B肽的已知抑制剂计算的分子间相互作用的分数进行了验证。本文还引入了一种新型的FIPSDock对接算法,该算法实现了FIPS (Fully Swarm)优化方法的一种变体,采用AutoDock 4.20套件中新开发的能量函数来解决柔性蛋白质与配体的对接问题,作为标准的指纹交互工具,提高了我们的搜索能力和对接精度,并首次通过多个同类对接实验对其进行了评估。更重要的是,我们的多共价超配体结构4D反向对接方法针对PSO@AutoDock、SODOCK和AutoDock 4.20套件进行了交叉对接实验,对来自Sutherland-crossdock-set的8个蛋白质靶点(CDK2、ESR1、F2、MAPK14、MMP8、MMP13、PDE4B和PDE5A)的174个蛋白质配体复合物进行了交叉对接实验。PBE结合了介质中固定电荷的连续介质静电描述和水溶液中移动离子的玻尔兹曼处方在硅热平衡策略中:流动驱动的ImgLib2是基于可扩展滑动窗口的高效单倍型相位算法,该算法基于基于网格的PharmBench工作流中的三维药效团,是评估药效团解析方法的基准数据集。通过KNIME-RDkit-CDK,利用(Propeptide-Fc)/MGF噬菌体显示的随机肽库,模拟Wnt7a/Fzd7对Akt/mTOR合成代谢-I/MAPK/ERK途径的肌肉质量纤维大小的可能增加
