Proteomics has recently known huge development, particularly due to Mass Spectrometry.

This complex technology is now available for example in the hospital-based analysis laboratories. With MALDI-TOF it is now possible to identify bacterial species in a few minutes starting from a single colony on a plate.áWith tandem Mass Spectrometry SRM (Selected Reaction Monitoring) mode, the protein quantification is strongly improved, thus allowing to treat complex samples without preliminary costly and time consuming protein extraction steps.

The untargeted identification (said shotgun proteomics) and relative quantification of proteins (said label-free) now achieves such performances which allow samples comparisons such as treated vs control or pathologic vs safe.

These new advances produce huge amounts of data and needs new bioinformatics tool in order to process efficiently these data such as our CORAVALID module

Something to assess...



Approaches on therapeutic drug or cosmetic active ingredient effects are highly dependent on available analytical techniques. For the last 40 years, they have been driven by targeted techniques such as ELISA or PCR: These follow with narrow specificity, a particular molecule that has been identified as "the" marker of the biological phenomenon we want to track. So we study positive effects on a biological phenomenon, and then we look at the negative effects.

Recently, high-throughput sequencing techniques or LC-MS/MS introduced a drastic change in our way to assess an active molecule effects, as they allow identification and quantification of up to thousands of molecules at a time, without targeting beforehand. Such techniques generate masses of data, usually difficult to be processed which led us to rapidly develop complementary methods of Biostatistics and Bioinformatics as our CORAVALID method.

Also, given the results, usual reactions are along the line of "Where is my marker?". "Why all the molecules are moving?". "It's much more complicated than what I thought, so I will look at these first ..".

We do not have to be afraid of these innovative approaches. For instance, it is particularly fruitfulá understanding the molecular effects on a cell proteome by comparison of proteome of test vs. control. We quickly see the positive or negative impacts on metabolic pathways, biological and molecular functions, cell components and interactors.áHaving such information on early research stages is much more interesting as discovering it during later development. It avoids discovering it at a later development stage and of course at a higher cost !
