The UCSC Genome Browser Introduction. Biotechnology Annual Review - UCSC Genome Browser: Deep support for molecular biomedical research. Molecular Biotechnology, Volume 38, Number 3. For beginners in the field, this review highlights the key features of the genome browser at UCSC for data display, and provides nearly step-by-step procedures for creating publication quality maps.
The browser offers an engine (Blat) for searching a known genomic DNA for correspondence with protein and DNA sequences specified by the user. The results provide links to graphical displays, known as maps. Users can create “designer maps” by adding Tracks to view various types of data and specific landmarks. The browser offers an extensive list of options. They include the position of annotated genes, the position of reference cDNA sequences (RefSeq from GenBank), the position of alternatively spliced mRNA species, and predictions derived from computational models to identify potential transcription start sites and potential protein binding elements in genomic DNA.

As a science journalist, I sympathize with book reviewers who wrestle with the question of whether to write negative reviews.
It seems a waste of time to write about a dog of a book when there are so many other worthy ones; but readers deserve to know if Oprah is touting a real stinker. On 2 April, Science Translational Medicine published a study on DNA’s shortcomings in predicting disease. All genomes are dysfunctional: broken genes in healthy individuals. Breakdown of the number of loss-of-function variants in a "typical" genome I don’t normally blog here about my own research, but I’m making an exception for this paper.
There are a few reasons to single this paper out: firstly, it’s in Science (!) ; and secondly, no fewer than five Genomes Unzipped members (me, Luke, Joe, Don and Jeff) are co-authors. For me it also represents the culmination of a fantastic postdoc position at the Wellcome Trust Sanger Institute (for those who haven’t heard on Twitter, I’ll be starting up a new research group at Massachusetts General Hospital in Boston next month). Readers who don’t have a Science subscription can access a pre-formatted version of the manuscript here. First, some background The idea is very simple.
Cryptic genetic variation promotes rapid evolutionary adaptation in an RNA enzyme (Hayden et al, Nature, 2011) Background Cryptic genetic variation (CGV) is defined as “standing genetic variation that does not contribute to the normal range of phenotypes observed in a population, but that is available to modify a phenotype that arises after environmental change or the introduction of novel alleles” [Gibson & Dworkin, 2004].
As such, CGV fills the gap between : 1. expressed genetic variation, defined as genetic variation that contributes to the normal range of phenotypes actually present in a population ; 2. neutral genetic variation, that does not contribute to phenotypes under any likely genetic or environmental conditions ; a typical example of neutral genetic variation would be synonymous substitutions in protein coding sequences. NIH VideoCasting and Podcasting. VideoCasting - Cancer Genomes Analysis: Computational Challenges and Approaches. Dr.
Getz will discuss how the recent revolution in sequencing technologies has enabled comprehensive characterization of many thousands of cancer genomes, for example from The Cancer Genome Atlas (TCGA) and the International Cancer Genome Consortium (ICGC). These resulting data pose new computational challenges in detecting the various genomic alterations in the cancer genomes from sequencing data, understanding the mechanisms that create them, and dealing with heterogeneous samples. In addition, he will discuss the greatest challenge is how to introduce these findings to clinical trials and standard practice. The revolution in sequencing technologies in recent years has enabled comprehensive characterization of many thousands of cancer genomes (e.g. Scientific Program. 近年様々なローンが販売されるようになり、目的に応じた個性的なローンの人気が急上昇中です。

Introduction to automatic gene annotation (Cold Spring Harbor, NY, US) Chromosome Diagrams in Biopython. Online lecture series on genomics and bioinformatics. A current lecture course surveying genomics and bioinformatics is available online, hosted on YouTube by GenomeTV.
Handouts for the thirteen week course are hosted on the course website. We’re told that the course includes an update on technologies that have changed over the past two years. These lectures are introductory. They are aimed at biologists who wish to learn more about genomics or bioinformatics, perhaps because their upcoming work intersects with it, rather those who already have some detailed knowledge or experience of the field. I would add that, being lectures, they are high-flying in the sense that they do not deal with the actual hands-on work involved, which introduces finer detail and further issues not covered in these lectures.
The lectures cover a wide range of topics; the full schedule is shown below. Here’s the full course schedule: Readers looking for slides of the talks, should check the handouts available on the course website. The Genomic Landscape circa 2012.

Guide to the UCSC Genome Browser. De novo genome assembly: what every biologist should know : Nature Methods. Asked how mature the field of genome assembly is, Ian Korf at the University of California, Davis, compares it to a teenager with great capabilities.
“It's got bold assertions about what it can do, but at the same time it's making embarrassing mistakes,” he says. Perhaps the biggest barrier to maturity is that there are few ways to distinguish true insight from foolish gaffe. When a species' genome is newly assembled, no one knows what's real, what's missing, and what's experimental artifact. That's not slowing the pace of assembly. In 2009, entomologists launched an initiative to sequence 5,000 insect genomes in a project known as i5k. Dozens of computer programs have been written to turn raw sequencing data into intact assemblies. Kelly Howe, Lawrence Berkeley Laboratory Assemblers need copious sequencing data and informatic exertion to put the genome back together. Millions of pieces with multiple copies Short-read sequencing technologies have made the computational challenge harder.
