Data processing (pipeline) workflow (done using Mouse_mm9_v1 base repository)

1. If each sample has more than one fastq file (per sequencing read) then fastq files merging-step is performed

2. Transeq Reads pre-processing (5’ GGG trimming & polyA & polyT removal)

3. Processed-reads Mapping (using TopHat)4. TES reads coverage profile (Transeq protocol QC step) 5. Reads Count (per 3’UTR) (using HTSeq-count)6. Data Normalization and Differential Gene Expression (using DESeq2)7. QC: Principal Component Analysis (PCA) & Hierarchical Clustering

• Differential gene expression data is assessed by DESeq2• DESeq output is summarized in a single

sheet per experiment• Genes differentially-expressed during each

time series were called by two independent means:

I. Using pairwise comparison vs. time zeroII. Using a tool named: maSigPro

RNA-Seq drug dose response (1000 and 100)/time series (0, 1, 6 and 12 hrs) gene filtering criteria

• The data filters used during the last analysis performed (12.08.15):I. maSigPro: • NormCounts of genes meeting MaxRawCount>50 served as input; • maSigPro output was further filtered against potential outlier genes (flagged

by maSigPro) • Genes showing FC greater than 1.5 (at least in one of the paired-comparisons); • By default maSigPro requires (BH) adjusted p-value <0.05 II. Pairwise comparison criteria:

MaxRawCount>50, adjusted-p-value<0.05 and FC greater than 1.5 (at least in one of the paired-comparisons);

Exp 4.2: Mouse primary beta cells:Genes meeting criteria: Paired-comparison yields higher

100/1000 gene overlap (than the one obtained with maSigPro)

maSigPro filtered output Pairwise-comparison filtered output

Exp 4.2: Mouse primary beta cells: Most of maSigPro shared-genes are included

in the group of paired shared genes

To determine which output is preferred data validation using an orthogonal method is essential

• Generally this experiment yielded less significant results• When applying the same filters used for the primary beta-cells

datasets, very few genes pass; • The possibility of using p-value (instead of adjusted-p-value should be

tested by the investigator)• The level of 100/1000 intersection (shared-genes) is lower here

compared to the one observed in the primary cells experiment

TranSeq datasets

• Low overall intersection between the primary and the cell-line ‘significant’

genes;• Relatively low intersection between the

two drug concentrations tested on the beta cell line
