Generic properties of random gene regulatory networksQuantitative Biology - Tập 1 - Trang 253-260 - 2014
Zhiyuan Li, Simone Bianco, Zhaoyang Zhang, Chao Tang
Modeling gene regulatory networks (GRNs) is an important topic in systems biology. Although there has been much work focusing on various specific systems, the generic behavior of GRNs with continuous variables is still elusive. In particular, it is not clear typically how attractors partition among the three types of orbits: steady state, periodic and chaotic, and how the dynamical properties chan...... hiện toàn bộ
System identification and parameter estimation in mathematical medicine: examples demonstrated for prostate cancerQuantitative Biology - - 2016
Yoshito Hirata, Kai Morino, Taiji Suzuki, Qian Guo, Hiroshi Fukuhara, Kazuyuki Aihara
We review our studies on how to identify the most appropriate models of diseases, and how to determine their parameters in a quantitative manner given a short time series of biomarkers, using intermittent androgen deprivation therapy of prostate cancer as an example. Recently, it has become possible to estimate the specific parameters of individual patients within a reasonable time by employing th...... hiện toàn bộ
Synthetic biology: a new approach to study biological pattern formationQuantitative Biology - Tập 1 - Trang 246-252 - 2014
Chenli Liu, Xiongfei Fu, Jian-Dong Huang
The principles and molecular mechanisms underlying biological pattern formation are difficult to elucidate in most cases due to the overwhelming physiologic complexity associated with the natural context. The understanding of a particular mechanism, not to speak of underlying universal principles, is difficult due to the diversity and uncertainty of the biological systems. Although current genetic...... hiện toàn bộ

MRHCA: a nonparametric statistics based method for hub and co-expression module identification in large gene co-expression networkQuantitative Biology - Tập 6 - Trang 40-55 - 2018
Yu Zhang, Sha Cao, Jing Zhao, Burair Alsaihati, Qin Ma, Chi Zhang
Gene co-expression and differential co-expression analysis has been increasingly used to study cofunctional and co-regulatory biological mechanisms from large scale transcriptomics data sets. In this study, we develop a nonparametric approach to identify hub genes and modules in a large coexpression network with low computational and memory cost, namely MRHCA. We have applied the method to simulat...... hiện toàn bộ
Comprehensive simulation of metagenomic sequencing data with non‐uniform sampling distributionQuantitative Biology - Tập 6 Số 2 - Trang 175-185 - 2018
Shansong Liu, Kui Hua, Sijie Chen, Xuegong Zhang
BackgroundMetagenomic sequencing is a complex sampling procedure from unknown mixtures of many genomes. Having metagenome data with known genome compositions is essential for both benchmarking bioinformatics software and for investigating influences of various factors on the data. Compared to data from real microbiome samples or from defined microbial moc...... hiện toàn bộ
