Abstract for seminar at Tel Aviv University
Abstract:
The ENCODE and modENCODE consortia have generated a resource
containing large amounts of transcriptomic data, extensive mapping of
chromatin states, as well as the binding locations of over 300
transcription-regulatory factors for human, worm and fly. The
consortium performed
extensive data integration on this data set. Here
I will give an overview of the data and some of the key analyses.
In particular:
(1) Conservation & Divergence of Transcription
(1a) A novel cross-species clustering algorithm to
integrate the co-expression networks of the three species, resulting in
conserved modules shared between the organisms. These modules are
enriched in developmental genes and exhibited hourglass behavior.
(1b) The extent of the non-coding, non-canonical
transcription is consistent between worm, fly and human.
(1c) In contrast, analyses of pseudogene (fossil genes) show that they
diverged greatly between the organisms, much more so than genes.
Nevertheless, they had a consistent amount of residual transcription.
(2) Conservation of Regulation
(2a) A global optimization algorithm to examine the
hierarchical organization of the regulatory network.
Despite extensive rewiring of binding targets, high-level organization
principles such as a three-layer hierarchy are conserved across the
three species.
(2b) The gene expression levels in the organisms, both coding
and non-coding, can be predicted consistently based on their upstream
histone marks. In fact, a "universal model" with a single set of
cross-organism parameters can predict expression level for both protein
coding genes and ncRNAs.

Abstract for Talk at BioIT World 2015
Identification of noncoding cancer "drivers" from thousands of somatic
alterations is an unsolved problem. Here, we developed a computational
framework to annotate cancer regulatory mutations. The framework
combines an adjustable data context summarizing large-scale genomics
and cancer-relevant datasets with an efficient variant prioritization
pipeline. To prioritize high impact variants, we developed a weighted
scoring scheme to score each mutation's impact.

Weizmann Institute, on June 7th-11th, 2015
Title: Analysis of Protein Networks
Protein-protein interaction (PPI) networks may be studied through the
lens of both 3-dimensional protein structures as well as the
large-scale genome variation data being generated as part of
next-generation sequencing initiatives. In terms of protein structural
data, I will describe how mapping the structures of protein complexes
onto PPI networks enables the classification of hubs into two distinct
types: multi- and singlish-interface. These two categories exhibit
very distinct properties, especially in terms of the well-known
preferential attachment model of network growth. Secondly, I will
discuss how the integration of alternative conformations with PPI
networks further highlights interesting disparities, with the
permanent multi-interface hubs tending to exhibit a greater degree of
conformational plasticity relative to singlish-interface hubs. In
addition, I will briefly discuss how alternative conformations are
being culled from the PDB to study the significance of sequence
variation in the context of allosteric behavior. I will then discuss
the some of the insights gained by integrating variation data with
these networks (especially when using population-scale sequencing data
from the 1000 Genomes Project). Several well-known results are
recapitulated using this data: greater network centralityis associated
with a greater degree of negative selection, and the proclivity of the
network tends to be under positive selection. Finally, I will show how
this type of data further illuminates aspects of the intricacies of
protein structures and motions.
Integration of protein motions with molecular networks reveals
different mechanisms for permanent and transient interactions.
