Selecting the most appropriate time points to profile in high-throughpsut studies


Our next meeting will be at 3:00 on May 26th, in room 4160 of the Discovery building. Our Selected paper is Selecting the most appropriate time points to profile in high-throughpsut studies.
The abstract is as follows.

Biological systems are increasingly being studied by high throughput profiling of molecular data over time. Determining the set of time points to sample in studies that profile several different types of molecular data is still challenging. Here we present the Time Point Selection (TPS) method that solves this combinatorial problem in a principled and practical way. TPS utilizes expression data from a small set of genes sampled at a high rate. As we show by applying TPS to study mouse lung development, the points selected by TPS can be used to reconstruct an accurate representation for the expression values of the non selected points. Further, even though the selection is only based on gene expression, these points are also appropriate for representing a much larger set of protein, miRNA and DNA methylation changes over time. TPS can thus serve as a key design strategy for high throughput time series experiments.

We welcome all who can join us for this discussion. Feel free to begin that discussion in the comments section below.
