MOTIVATION: Gene expression profiling using RNA-seq is a powerful technique for
screening RNA species' landscapes and their dynamics in an unbiased way. While
several advanced methods exist for differential expression analysis of RNA-seq
data, proper tools to anal.yze RNA-seq time-course have not been proposed.
RESULTS: In this study, we use RNA-seq to measure gene expression during the
early human T helper 17 (Th17) cell differentiation and T-: cell activation
(Th0). To quantify Th17-: specific gene expression dynamics, we present a novel
statistical methodology, DyNB, for analyzing time-course RNA-seq data. We use
non-parametric Gaussian processes to model temporal correlation in gene
expression and combine that with negative binomial likelihood for the count data.
To account for experiment-: specific biases in gene expression dynamics, such as
differences in cell differentiation efficiencies, we propose a method to rescale
the dynamics between replicated measurements. We develop an MCMC sampling method
to make inference of differential expression dynamics between conditions. DyNB
identifies several known and novel genes involved in Th17 differentiation.
Analysis of differentiation efficiencies revealed consistent patterns in gene
expression dynamics between different cultures. We use qRT-PCR to validate
differential expression and differentiation efficiencies for selected genes.
Comparison of the results with those obtained via traditional timepoint-: wise
analysis shows that time-course analysis together with time rescaling between
cultures identifies differentially expressed genes which would not otherwise be
detected. AVAILABILITY: An implementation of the proposed computational methods
will be available at http://research.ics.aalto.fi/csb/software/
