As part of efforts to validate discovery- and target-based protein quantification using iTRAQ and PQD, Wu and co-workers recently reported a change in expression of certain proteins in WT and kin- S49 cells treated with 8-CPT-cAMP for 4 h.
Given the sparseness of the fossil record, there is no guarantee of unearthing evidence of such species, but, in the cases of legs and eyes, the predictions have been validated by discoveries made over the past decades.
To test the validity of our approach, the results of our scan was applied to previously nominated regions to explore how well this method validated previous discoveries.
Investigators have typically "validated" the discoveries by demonstrating that the sub-types possess distinct clinical characteristics, such as case survival.
Gunther Stent, one of the original thinkers in the field of molecular biology, whose research wrestled with and validated the breakthrough discovery of the structure of DNA, died Thursday near his home in Haverford, Pa.
We validated this discovery with a receptor activation assay in COS-7 cells expressing Sv-TKIR, using a reporter SRE-LUC system designed for RTKs, with each of the rIAG proteins acting as the activation ligand.
In order to validate our discoveries using independent experimental means, we performed quantitative real-time PCR (qPCR) experiments for 30 of the regions containing putatively aberrant SNPs, using DNA from individuals in our sample set.
Additionally, high dimensionality compromises the ability to validate marker discovery, which requires accurately measuring true and false discovery rates (Ransohoff, 2005).
In this commentary, we provide an overview of the immunoinformatics process leading to the discovery of tolerizing epitopes in pathogen genomic sequences, provide a brief summary of laboratory data that validates the discovery, and point the way forward.
As for biological validation, the same 450 k array data from which the grade-CpG profiles were obtained, were previously validated in 15 discovery and 24 validation paired aortic samples [ 9], including the grade-CpG-harboring genes PDGFA and C9orf3/MIR23b.
