Genomics and Epigenetics

Studying the Epigenome by Next Generation Sequencing

The epigenome has been in the research spotlight, and for good reason. Not only has it been associated with the developmental stages of an organism, but epigenetic alterations lead to disorders and have been linked to many human diseases. So, the question stands: what exactly is an epigenome? What Is the Epigenome? Simply put, the…

Using dbSNP and ClinVar to Classify Gene Variants

As we discussed previously, the gaps in our understanding of the human genome make variant classification an extremely difficult job. However, with each passing day our knowledge increases, and the tools to help us become increasingly more efficient. Let’s pick up where we left off in our first article about variants. After checking Ensemble to…

ChIP-seq Workflows Run Best with Automated DNA Size Selection

Chromatin immunoprecipitation sequencing, better known as ChIP-seq, is a massively parallel approach for understanding the interactions between proteins and DNA. This is especially important for determining the activity of transcription factors, which is why it’s frequently used to learn about the complicated series of biological steps leading to cancer. It’s also key to many epigenetic…

Generating High-Quality Genome Assemblies from Metagenomic Sequencing

The decreasing costs in genomic sequencing over the past decade have inspired researchers to apply shotgun next-generation sequencing to entire microbial communities. While the reads generated typically cannot be assembled cleanly into individual genomes, there is often enough information produced to identify most microbes present in the population. However, this approach lacks sufficient resolution to…

Get to Know Your Reference Genome (GRCh37 vs GRCh38)

Whether your experiment relies upon a reference-based genome assembly or mapping reads to a reference genome to identify variants, you need to choose a human reference genome assembly. But wait! You go to the FTP site of NCBI’s refseq and click on the Homo sapiens folder. There you are presented with two choices. Which one…

CRISPR-Inspired Method Targets Large, Repetitive DNA Elements

Target capture through PCR has been a mainstay in genomics for years, but scientists working on especially repetitive, poorly characterized, or rapidly evolving regions continue to struggle to fish out those stretches of DNA for further study. However, whole genome sequencing, the only other alternative for these regions, can force researchers to pay for much…

De Novo DNA Sequencing and the Special k-mer

The technology for DNA sequencing was developed back in 1977 thanks to Frederick Sanger. It took a bit longer before it was possible to sequence a complete genome. This is because we needed an appropriate mathematical model and massive computational power to assemble millions or billions of small reads to a larger complete genome. Today’s…

How to Become a Bioinformatician

If you want to start a journey towards being a bioinformatician, you must first know the meaning of the term bioinformatics. You will also need to know what bioinformaticians do, and what you need to know to land your first entry level job as a bioinformatician. Most bioinformaticians work within different medical science and health…

A Crash Course in BLAST Searching

Simple BLAST searching is pretty straightforward to many of us. Just plug in your sequence, select the species genome, and hit search! But have you ever wondered what it takes to run a BLAST query using these mammoth-sized (no pun intended!) sequence databases? BLAST searching can produce dozens, hundreds, or even thousands of candidate alignments.…

How to Use Ensembl to Classify Gene Variants

Even though our knowledge about genomes grows daily, and in huge leaps, we sometimes need to remind ourselves that DNA was first isolated in 1869 and its molecular structure was only identified in 1953. The PCR reaction only hit the scientific community as recently as 1983! So even though we are growing fast, we are…

Next Gen Sequencing Challenges

Next generation sequencing opened the doors to our genome. It gives massive amounts of information in a week – whereas Sanger sequencing takes thrice as long, and causes lab lesions due to the abusive use of pipettes. Indeed, with minimal hands-on procedures we obtain a lot of data. But nothing in Science is ever easy.…

DNA Extraction from FFPE Tissues for NextGen Sequencing

Rapid genomic analysis offered by next generation sequencing (NGS) is ideal for personalized medicine approaches to clinical genetics, microbiological profiling, and diagnostic oncology. Many standard clinical samples are preserved as formalin-fixed, paraffin-embedded (FFPE) tissues, which presents obstacles for use in NGS analysis. FFPE tissue preservation has the benefit of keeping samples intact for histological examination…
