  • dosage analysis

    Hi everyone,

    I designed an experiment looking at differential expression in a certain group of cells after overexpression of a gene in a neighbouring group of cells. In order to overexpress my gene (and overexpress its control gene in the controls), I needed to use temperature induction (those familiar with the dmel GAL4/GAL80ts system, that is what i used). That leaves me with RNA-seq data of the following description

    12 Hr heat induction of expression - 3 bio reps of treatment / 3 bio reps of control

    24 Hr heat induction of expression - 3 bio reps of treatment / 3 bio reps of control

    48 Hr heat induction of expression - 3 bio reps of treatment / 3 bio reps of control

    It seems that DESeq/edgeR only take factors as the variables. Are there any DE platforms that allow gene expression to be modelled against dosage/time?

    DESeq/edgeR will handle that just fine. You can input numeric values into your model if that's what you want (search the bioconductor email list for a number of examples of this being done).

      I have checked the list, and have not managed to find what you are talking about. I do see many messages where Simon and Wolfgang ask for more details on the experiments (most of these go back to 2012 and 2011), but it seems they direct people away from doing time course analysis. Please send a link to the messages you are talking about.

        I did find a thread on SEQanswers from June that you helped on. I will try your recommendations from that.

          Strategies for Sequencing Challenging Samples
          by seqadmin


          Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
