Int J Gynecol Cancer. One way to better define the different endotypes is to generate molecular fingerprints e. Since the early days of medicine, practitioners have always combined their observations from patient examinations with their medical knowledge and experience to diagnose medical conditions and find treatments tailored to the patient [ 1 ]. J Am Med Inform Assoc. The latter can be combined to study patients e.

The survival status of the patients is then translated as a color scheme blue representing deceased patients and red alive patients. Such missing values may be handled through imputation to the mean, mode, mean of nearest neighbours, or by multiple imputation etc. Protein identification in the post-genome era: Cambridge University Press; E2F transcription factors and digestive system malignancies: Efforts are made in the systems biology community to correct these shortcomings, among which the disease maps mentioned above. From proteins to proteomes:

Open in a separate window. Any meaningful experiment relies on a robust, bias-controlled study design [ 42 ] using appropriate technologies, leading to the production of trustworthy quality-checked data.

Were there bells and whistles? Annotation is a complex task that links identifiers from the technological platforms to existing entities i. Jonathan van Eyll, Email: From proteins to proteomes: Biological annotation can be performed using pathways see review in [ 97 ] or functional categories reviewed in [ 98 ] ; however, this kind of analysis is hampered by factors such as statistical considerations which method to use, independence between genes and between pathways, how to take into account the magnitude of the changes and pathway architecture considerations pathways can cross and overlap, meaning that if one pathway is truly affected, one may observe other pathways being significantly affected due to the set of overlapping genes and proteins involved [ 99 ].

The reduced data also allows for the definition of a higher number of stable groups 9 instead of 4thereby pointing to the usefulness of performing feature reduction prior to clustering analysis. The performances were then estimated within the training model by 10 repeats of fold validation and the prediction power estimated in the testing set.

Our article focuses on the identification of disease mechanisms through statistical analysis of raw data, annotation with up-to-date ontologies to generate fingerprints biomarker signatures derived from data collected from a single technical platformhandprints biomarker signatures derived from data collected within multiple technical platforms, either by fusion of multiple fingerprints or by direct integration of several data types and interpretation on a pathway level to identify disease-driving mechanisms.

The analysis generated a higher number of stable and clinically relevant clusters than previously reported, and enabled the generation of predictive models of patient outcomes.
