An elaborate system of transcription regulation is responsible for the morphological and behavioral complexity in higher eukaryotes. This regulatory system consists of diverse trans-acting protein factors and cis-acting regulatory DNA sequences. Recently, Chromatin ImmunoPrecipitation coupled with whole genome tiled microarray (ChIP-chip) and/or next-generation sequencing (Solexa, SOLid and 454) has evolved as a powerful and unbiased technique to study genome-wide in vivo binding of the trans-acting protein factors. The application of this technology to multiple factors and/or in multiple conditions allows biologists to study how trans-factors differentially regulate transcription in a combinatorial manner. However, it also poses great challenges for the development of effective algorithms, the key link between massive raw data and biological hypotheses.  
. 09/2014:  Liguo's ChIP-exo methodology paper (MACE) is accepted to '''Nucleic Acids Research'''.  MACE is recommended by Active Motif as the software solution for the company's new [https://www.activemotif.com/catalog/1050/chip-exo ChIP-exo kit and service].


We developed a series of  algorithms to reliably detect and annotate ChIP-enriched regions using Affymetrix whole-genome tiling arrays, including 1) Model-based Analysis of Tiling-arrays (MAT; PNAS 2006) and a hidden Markov model (Bioinformatics 2005) for ChIP-region detection, 2) extreme MApping of OligoNucleotide (xMAN, BMC Genomics 2007) for microarray probe mapping, 3) Cis-regulatory Element Annotation System (CEAS; NAR 2006) for ChIP-region annotation. Since the inception in early 2006, they have been adopted by hundreds of academic users and are now considered as the ChIP-chip data analysis standard in many labs. We are also working with the ENCODE spike-in consortium, which consists of more than 10 transcriptional regulation groups worldwide, to systematically analyze the performance variability introduced in ChIP-chip protocols, array platforms, and analysis methods.

We are also in close collaboration with several labs on identifying global regulation targets of a series of key transcription factors, including estrogen receptor (Cell 2005; Nature Genetics 2006); androgen receptor (Molecular Cell 2007); STAT5 (J.
