SPaRTAN, a computational framework for linking cell-surface receptors to transcriptional regulators

Project description:The identity and functions of specialized cell types are dependent on the complex interplay between signaling and transcriptional networks. Recently single-cell technologies such as CITE-seq have been developed that enable simultaneous quantitative analysis of cell-surface receptor expression with transcriptional states. To date, these datasets have not been used to systematically develop cell-context-specific maps of the interface between signaling and transcriptional regulators orchestrating cellular identity and function. We present SPaRTAN (Single-cell Proteomic and RNA based Transcription factor Activity Network), a computational method to link cell-surface receptors to transcription factors (TFs) by exploiting cellular indexing of transcriptomes and epitopes by sequencing (CITE-seq) datasets with cis-regulatory information. SPaRTAN is applied to immune cell types in the blood to predict the coupling of signaling receptors with cell context-specific TFs. The predictions are validated by prior knowledge and flow cytometry analyses. SPaRTAN is then used to predict the signaling coupled TF states of tumor infiltrating CD8+ T cells in malignant peritoneal and pleural mesotheliomas. SPaRTAN greatly enhances the utility of CITE-seq datasets to uncover TF and cell-surface receptor relationships in diverse cellular states.

Identification of transcription factors dictating blood cell development using a bidirectional transcription network-based computational framework [RNAseq_THP1_GSK-LSD1]

Project description:Genome-wide transcription factor binding profiles provide valuable insights into hematopoietic development and malignancies. Today, advanced computational methods exploit cis-regulatory information to predict complex gene regulatory networks controlled by transcription factors. However, these prediction methods still require large amounts of reference data or experimental expertise. Here, we present a low-requirement network-based computational framework that exploits bidirectional transcription marked regulatory elements to identify important transcription factors driving hematopoietic decision making. Using CAGE-seq we predicted TF binding and confirmed experimentally validated TF important in cell conversion strategies by exploiting bidirectional regions. Next, we applied our framework to predict driving transcription factors in induced normal erythropoiesis and early myelopoiesis, as well as in acute myeloid leukemia associated MLL-AF9-driven immortalisation. Our approach allowed the identification of experimentally validated as well as thus far unexplored transcription factors in these processes.

A computational framework for identifying promoter sequences in non-model organisms using RNA-seq datasets

Project description:We developed a computational framework to discover short DNA sequences that confer strong expression in non-model organisms. The framework relies solely on whole genome and RNA sequencing data types, which are easily accessible to a variety of research groups. The framework proceeds in three main stages: 1) identification of a group of highly expressed loci that maintain high transcript counts across a broad range of experimental conditions, 2) extraction of the corresponding upstream candidate promoter regions of these highly expressed loci while minding nearby annotations and avoiding those that may potentially reside in operons, and 3) application of the motif finding algorithm in BioProspector to these upstream regions to predict the location and sequence of the -35 and -10 hexamers that drive the strong expression of these loci. Ultimately, we report sequences of 27-30 bases in length as candidate -35, -10 signals for each of the top loci and create a consensus motif from these predictions. We apply our framework to 80 RNA-seq datasets collected for the methanotroph Methylotuvimicrobium buryatense 5GB1 and validate our predictions computationally and experimentally. The data deposited here represent all RNA-seq data that, until this study, has not previously been published.
