MAKE SENSE OF YOUR OMICS DATA
INTEGRATIVE DATA ANALYSIS IN LIFE SCIENCES
WHAT ARE OMICS DATA? ▸ Allow the simultaneous analysis of a great number of measures:
• DNA : Genomic (SNP, DNA rearrangements,…), Epigenomic (methylation, histone modifications,…)
• RNA : Transcriptomic (differential expression, alternative splicing, lncRNA, miRNA,…)
• Proteins : Proteomic (differential expression) ‣ With the aim of:
• Caracterizing new models • Identifying molecular mecanisms/markers of pathology • Following biological ways of interest (oxydative stress, immune
response,…) • Caracterizing the effect of treatments at different doses • Studying the microbiote
Transcriptomic (DNA chip, RNA-Seq)
Proteomic (LC-MS/MS)
Genomic/Epigenomic (DNA chip, NGS)

DATA PREPROCESSING▸ Quality controls are performed at different step:
• Molecular (RNA, cDNA, protein,…) • Technologic (hybridation, reads, mapping, missing
values,…) • Experimental (contaminations, annotation errors,
hidden factors,…) ▸ Adapted data normalization for each technology:
• Background correction • Variance stabilization • Quantile normalization
▸ Treatment of the calcul units • Probe merging/separation related to their behaviour to
optimize modulation detection

Heat-MapDATA ANALYSIS▸ Use of unsupervised approaches to identify the
variabilty sources: • Principal component analysis (PCA) • Hierarchical clustering • Heat-Maps • Segregating genesets
▸ Ad-hoc statisical analysis at the gene and genesets level taking into account the variability sources: • Donor effect • Batch effect • Experimental conditions effect
