What is 'omics'?

"Omics" is derived from the Latin suffix "ome" meaning "mass" or "many".
OMICS involve many measurements per endpoint.
Integrating OMICS data helps discover disease causes and states.

OMICS Field

The OMICS field covers genomics (genome), proteomics (proteome), and metabolomics (metabolome).

Types of Genomics

Includes transcriptomics, pharmacogenomics, nutrigenomics, interactome, epigenetics, and proteomics
Some fields show dynamic output as a result of static DNA content.

Dynamic Components of Genome

transposable elements
retrotransposons
transposons (LINES +SINEs)

Biological effects of transposable elements

Sequence broadcasting
Altering properties of genes
Evolution
Chromosomal rearrangements
Epigenetic modifications

Categories of Genomics

Genotyping: Focuses on the genome sequence to determine gene function and disease susceptibility
Transcriptomics: Focuses on mRNA transcript abundance mirroring gene expression levels.
Epigenomics: Studies epigenetic processes influencing gene expression not involving DNA modification

Proteomics

Proteomics examines proteins in biological systems and their role
The proteome (all proteins in a specific cell type or tissue) varies over time, across cell types, and in response to environmental conditions.

Tools for Proteomics

Mass spectrometry (MS)
Protein microarrays

Introduction to Genomics

Genome sequencing projects aim to understand the structure and function of genomes.
Techniques for sequencing genomes are becoming easier and faster, allowing for more comprehensive analysis of the human genome.
There are completed genome projects of various species.

Human Genome Project (HGP)

Officially begun in 1990.
Planned for 15 years (1990-2005).
Involved 18 countries with significant contributions from the USA, UK, Germany, France, Japan, and China

Human Genome Project - Goal

Identifying 100,000 genes in human DNA
Determining the sequences of 3 billion chemical bases
Storing genomic information in databases
Developing faster sequencing technologies
Building tools for genomic data analysis
Addressing ethical, legal, and social issues related to the human genome project.

Recent Progress on HGP

Dec 1999: Completion of Chromosome 22
Mar 2000: Drosophila Genome completed
Apr 2000 - May 2000: Completion of draft sequences of several human chromosomes.
June 2000: Announcement of a working draft of the human genome.
By 2003: Completion of the human genome.

Benefits of HGP

Identifying individuals at risk of diseases
Predicting disease course
Precise disease diagnosis
Developing new treatments.

FAQs on HGP

Whose genome is sequenced in HGP?: Blood (female) or sperm from numerous donors, including some pioneers like James Watson and Craig Venter
What genomes are fully sequenced?: Viruses, bacteria, yeast, roundworms, fruit flies, and the first plant genome in 2000.

The Human Genome

A human genome contains approximately 3.2 billion base pairs distributed across 22 paired chromosomes plus two sex chromosomes (X and Y).
Advances in sequencing technology have made it cheaper and faster.
Phenotype is a complex outcome of genotype, environment, life history, and epigenetics (the study of changes in gene expression that do not involve changes to the underlying DNA sequence).

International HapMap Project: Studies variation in human sequences around the world. An "atlas" of SNPs (single nucleotide polymorphisms).
1000 Genomes Project: Aims for complete genome data, detailed sequencing of 1000 individuals, and protein-coding regions analysis in families.
Private companies offer personal genome sequencing.
