YTRP: a repository for yeast transcriptional regulatory pathways

Abstract: Regulatory targets of transcription factors (TFs) can be identified by the TF perturbation experiments, which reveal the expression changes owing to the perturbation (deletion or overexpression) of TFs. But the identified targets of a given TF consist of both direct and indirect regulatory targets. It has been shown that most of the TFPE-identified regulatory targets are indirect, indicating that TF-gene regulation is mainly through transcriptional regulatory pathways (TRPs) consisting of intermediate TFs.

“…First, yeast is the only organism which has more than 206000 TF-gene documented regulation data available. The useful TF-gene documented regulation data [ 29 ], which provide the experimentally validated regulatory relationships between TFs and genes, are collected from more than 1300 published papers by the team of the YEASTRACT database [ 18 ]. Second, yeast is the only organism that is tested by more than 10 existing algorithms.…”

“…To overcome this obstacle, a modified approximation algorithm based on biological constraints was devised. In cells, the metabolism pathways and modules are usually energy conserved [8, 52]. This means that cells prefer to having fewer participating proteins if available.…”

“…Current genome-wide experimental methods for understanding the behaviors of how TFs control cellular gene expression can be divided into two categories [8, 9]. The first type of experiment is based on the chromatin immunoprecipitation (ChIP) techniques.…”

“…Transitive regulations can provide some evidence for time delays since they may result from the delays in gene regulation. Yang et al [153] provided yeast transcriptional regulatory pathways (YTRP) database, which recorded the possible transitive regulations. However, these YTRP edges are only predicted transitive regulation from shortest path method, but not validated by laboratory experiments.…”

“…A cell cycle is comprised of four phases: (i) Gap 1 (G1) is the checkpoint to ensure that it is ready for division, (ii) Synthesis (S Phase) involves DNA replication, (iii) Gap 2 (G2) is another checkpoint to ensure that the cell is ready to enter the next phase, and (iv) Mitotic (M Phase) refers to cell division. Two yeast cell cycle transcriptional regulatory networks (Net4 and Net5) were randomly chosen from YEASTRACT database[153,135] as benchmark networks for experiments.To show how well the proposed functional similarity measure, FS-GOE score, is able to recover benchmark networks, we also chose the integrated functional association score from STRING database ( http://string-db.org/) as a comparison since it quantitatively integrates multiple data sources including genome context, gene expression and literature, for generating functional association network(FAN)…”
