TITLE:

Analysis of Molecular Networks

Mark Gerstein

Yale University

My talk will be concerned with understanding protein function on a
genomic scale. My lab approaches this through the prediction and
analysis of biological networks, focusing on protein-protein
interaction and transcription-factor-target ones. I will describe how
these networks can be determined through integration of many genomic
features and how they can be analyzed in terms of various topological
statistics. In particular, I will discuss a number of recent analyses:
(1) Improving the prediction of molecular networks through systematic
training-set expansion; (2) Showing how the analysis of pathways
across environments potentially allows them to act as biosensors; (3a)
Analyzing the structure of the regulatory network indicates that it
has a hierarchical layout with the "middle-managers" acting as
information bottlenecks; (3b) Showing these middle managers tend be
arranged in various "partnership" structures giving the hierarchy a
"democratic character" ; (4) Showing that most human variation occurs
at the periphery of the protein interaction network; (5) Comparing the
topology and variation of the regulatory network to the call graph of
a computer operating system; and (5) Developing useful web-based tools
for the analysis of networks (TopNet and tYNA).

ANNOTATING NON-CODING REGIONS OF THE GENOME

Mark Gerstein

Yale U., New Haven, CT, USA

A central problem for 21st century science is annotating the human
genome and making this annotation useful for the interpretation of
personal genomes.  My talk will focus on annotating the bulk of the
genome that does not code for canonical genes, concentrating on
intergenic features such as TF binding sites, non-coding RNAs
(ncRNAs), and pseudogenes (protein fossils). I will describe an
overall framework for data integration that brings together different
evidence to annotate features such as binding sites and ncRNAs. Much
of this work has been carried out within the ENCODE and modENCODE
projects, and I will describe my approach interchangeably both in
human and various model organisms (e.g. worm). I will further explain
how many different annotations can be inter-related to characterize
the intergenic space, build regulatory networks, and construct
predictive models of gene expression from chromatin features and the
activity at binding sites.

TITLE:

Genome Annotation

Mark Gerstein, Yale University

ABSTRACT:

A central problem for 21st century science is annotating the human
genome and making this annotation useful for the interpretation of
personal genomes.  My talk will focus on annotating the 99% of the
genome that does not code for canonical genes, concentrating on
intergenic features such as structural variants (SVs), pseudogenes
(protein fossils), binding sites, and novel transcribed RNAs (ncRNAs).
In particular, I will describe how we identify regulatory sites and
variable blocks (SVs) based on processing next-generation sequencing
experiments.  I will further explain how we cluster together groups of
sites to create larger annotations. Next, I will discuss a
comprehensive pseudogene identification pipeline, which has enabled us
to identify >10K pseudogenes in the genome and analyze their
distribution with respect to age, protein family, and chromosomal
location. Throughout, I will try to introduce some of the
computational algorithms and approaches that are required for genome
annotation. Much of this work has been carried out in the framework of
the ENCODE, modENCODE, and 1000 genomes projects.
