    RNA-Seq and mouse reference genome

    Dear all,
    I like to check if someone here has experience on this mouse RNA-Seq data analysis.
    This is the mouse RNA-Seq with 50SR. Users wanted to just see the gene expression difference between different type of treatments compared with control. They used mouse strain Balb/C. We used mm9 from UCSC as reference genome to perform the Bioinformatics analysis including the TopHat and DEseq. This week, users revealed that this strain information (with emphasizing not the regular C57BL6 strain) and pointed out this whole genome sequencing information available for this strain: http://www.sanger.ac.uk/resources/mouse/genomes/ and ftp://ftp-mouse.sanger.ac.uk/current_denovo. They want us to download Balb/C strain genome and used it as the reference genome for this RNA-Seq project. From above, I didn't see any gene annotation file associated with this particular strain. I wonder how much difference it could be using the different strain as reference genome. Anyway, this RNA-Seq only looks for the gene expression difference. I want to check with people here to see if we have to re-perform the data analysis with the new reference genome. If yes, where could we get the new gene annotation file for the mouse strain Balb/C?

    Many thanks!

    sincerely

    Hi. I am currently using a mouse experiment and am looking for a reference genome for C57BL6 strain. Do you know where I can find the reference genome for this strain? I would prefer UCSC , this link shows many selections and I am not sure which to choose from?

        mm10 is the most recent version, just use that one.

        BTW, you'll find the Ensembl annotations to be superior, so I'd use their genome as well.

          Nine Things a Sample Prep Scientist Thinks About Before Sequencing
          by SEQadmin2


          I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

          Here are nine questions we think about, in roughly the order they matter, before...

          From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
          by SEQadmin2


          Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


          The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
