Study Notes

Introduction to Genomics and NGS

The study focuses on genomics and next-generation sequencing (NGS) techniques
The presentation details the application of big data analysis to genomics for medical research and biological systems.

What is Genome?

A genome is the entire genetic material of an organism
It consists of DNA (deoxyribonucleic acid)
Genomes also include noncoding DNA, mitochondrial DNA, and chloroplast DNA
Genomics is the study of genomes.

What is Genome Sequencing?

Sequencing technologies, such as NGS, are used to determine the order of nucleotides in a genome.
There are multiple generations of sequencers.
- First-generation sequencers. Sanger sequencing, relies on chain termination method.
- Second-generation: Next-generation or high-throughput sequencing, which largely uses parallel sequencing reaction. Examples include 454, Solexa, Ion torrent, and Illumina sequencing.
- Third-generation: These sequencers use single-molecule sequencing. Some examples are PacBio and Oxford Nanopore sequencing technologies.
The different sequencing methods and their capabilities and limitations are described in detail
Genomics libraries are created to prepare samples before performing next-generation sequencing or NGS.

Why "Big" data? How big?

Humans have an incredible number of cells (37.2 trillion)
The total mass of DNA in the human body is approximately 60 grams
The total length of human genome is about 3 billion base pairs

Sequencing Data Types

Different types of sequencing data exist to analyze multiple aspects of an organism
- Whole-genome sequencing (WGS): Analysis of the entire genome, including coding and non-coding regions.
- Whole-exome sequencing (WES): Analysis of all exons (protein-coding regions)
The data types are presented showing the data sizes are increasing continuously.

NGS

NGS is used to determine the order of nucleotides in DNA more quickly than standard Sanger sequencing and at a lower price.
Types of sequencing technologies are described
- Examples of sequencing devices are given (e.g., MiniSeq, MiSeq, NextSeq, HiSeq 4000, HiSeq X Ten)
Cost per genome analysis has been decreasing rapidly since 2000

Computational Biology

Computational Biology uses computational methods to analyze biological data, such as genomic data.
This technology helps discover biological insights and is used to solve complex problems.

Applications in Medicine and Research

Personalized medicine is based on an individual's genetic profile
Pharmacogenomics: Analyzing gene effects on drug response
Targeted therapies: Therapies that focus on precise genetic mutations
Diagnosis and risk assessment for various diseases
Understanding disease causes and their related genes
Studying human genetic diversity is important for population genetics and evolution
Studying the genetic history of humanity's origin

Microbiome and FMT (Fecal Microbiota Transplant)

Gut microbiota play a critical role in human health
Imbalances in the gut microbiota can lead to various diseases
FMT is a treatment that involves transplanting microbiota from a healthy donor to restore gut microbiota balance to help restore health.
Clinical trials of FMT in cancer or other conditions are noted

Data Analysis

Data mining is used to find meaningful aspects from a large dataset like the sequencing
Ways we apply computational algorithms to sequence data.
- Data types such as .fastq (a common sequencing output format), .sam and .bam (mapping datasets) and .vcf (variant calling formats) are explained

Metagenomics

Various techniques and processing steps used in metagenome analysis are provided
Examples of different types of data used in metagenome analysis are mentioned.
The different methods for analyzing microbiome composition and diversity are also included

General Information

The research and discovery of the human genome are discussed
Significant figures and events in genomics research are presented, such as the Human Genome Project and the 1000 Genomes Project.
The presentations include a brief summary of the major tools and concepts in genomics.
