The future of Illumina according to @chrissyfarr

In yesterdays Fast Company piece Christina Farr (on Twitter) gives a very nice write up of Illumina's history and where they are going with respect to bringing DNA sequencing into the clinic. I really liked the piece and wanted to share my thoughts after reading it with Core-Genomics readers.

Reporting on Fluidigm's single-cell user meeting at the Sanger Institute

The Genomics community is pushing ahead fast on single-cell analysis methods as these are revolutionising how we approach biological questions. Unfortunately my registration went in too late for the meeting running at the Sanger Institute this week (Follow #SCG16 on Twitter), but the Fluidigm pre-meeting was a great opportunity to hear what people are doing with their tech. And it should be a great opportunity to pick other users brains about their challenges with all single-cell methods.

Imaging mass-cytometry: the most exciting thing to happen in 'omics?

Mark Unger (Fluidigm VP of R&D) started the meeting off by asking the audience to consider the two axes of single-cell analysis: 1) Number of cells being analysed, 2) what questions can you ask of those cells (mRNA-seq is only one assay) - proteomics, epigenetics, SNPs, CNVs, etc.

Right now Fluidigm has the highest number of applications that can be run on single-cells with multiple Fluidigm and/or user developed protocols on the Fludigm Open App website; 10X Genomics only have single-cell 3' mRNA-seq right now, as do BioRad/Illumina and Drop-seq. But I am confident other providers will expand into non 3'mRNA assays...I'd go further and say that if they don't they'll find it hard to get traction as users are likely require a platform that can do more than one thing.

10X Genomics publications

Anyone that's been reading Core-Genomics will have seen my interest in the technology from 10X Genomics. I've been watching and waiting for publications to come out to get a better understanding of how people are using the technology and thought you might like my current list of articles: many of these are on the BioRxiv and should be available in a reputable journal if you're reading this in 2017 or later!

The number of 10X Genomics publications is going to grow rapidly; and this list will only be updated sporadically!

10X Genomics phasing explained

This post follows on from my previous one explaining the 10X Genomics single-cell mRNA-seq assay. This time round I'm really reviewing the method as described in a paper recently put up on the BioRxiv by 10X's Deanna Church and David JaffeDirect determination of diploid genome sequences. This follows on from the earlier Nat Methods paper which was the first 10X de novo assembly of NA12878, but on the GemCode system. While we are starting some phasing projects on our 10X Chromium box the more significant interest has been on the single cell applications. But if we can combine the two methods (or something else) to get single-cell CNV then 10X are onto a winner!

Nuclear sharks live for 400 years

A wonderful paper in a recent edition of Science uses radiocarbon dating to show that the Greenland shark can live for up to 400 years - making it the longest lived vertebrate known. See: Eye lens radiocarbon reveals centuries of longevity in the Greenland shark (Somniosus microcephalus).

Sequencing base modifications: going beyond mC and 5hmC

A great new resource was recently brought to my attention on Twitter and there is a paper describing it on the BioRxiv: DNAmod: the DNA modification database. Nearly all of the modified nucleotide sequencing we hear and read about is modifications to Cytosine mostly methyl cytosine and hydroxymethyl cytosine; you may also have heard about 8-oxoG if you are interested in FFPE analysis. All sorts of modified nucleotides occur in nature and may be important in biological processes where they can vary across tissue of an organism, or may just be chemical noise. The modifications are most important when they change the properties of the DNA strand, how is is read, and what might or might not bind to it e.g mC.

Celebrating 10 years at the CRUK-Cambridge Institute today

Today I have been working for Cancer Research UK for ten years! September 1st 2006 seems like such a short time ago but a huge amount has changed in that time in the world of Genomics. NGS has changed the way we do biology, and is changing the way we do medicine. The original Solexa SBS has been pushed hard by Illumina to give us the $1000 genome, and perhaps just as exciting are the results coming out of Oxford Nanopore's MAP community - this maybe the technology to displace Illumina? What the next ten years will hold is difficult to predict, but today I wanted to focus on the highlights of the last ten years at CRK for me.
