Journal ArticleDOI

The MicroArray Quality Control (MAQC) project shows inter- and intraplatform reproducibility of gene expression measurements

Leming Shi, +136 more
- 01 Sep 2006 - 
TL;DR: This study describes the experimental design and probe mapping efforts behind the MicroArray Quality Control project and shows intraplatform consistency across test sites as well as a high level of interplatform concordance in terms of genes identified as differentially expressed.
Journal ArticleDOI

The balance of reproducibility, sensitivity, and specificity of lists of differentially expressed genes in microarray studies

TL;DR: The results provide practical guidance to choose the appropriate FC and P-value cutoffs when selecting a given number of DEGs and recommend the use of FC-ranking plus a non-stringent P cutoff as a straightforward and baseline practice in order to generate more reproducible DEG lists.
Journal ArticleDOI

Pharmacogenomic Biomarker Information in Drug Labels Approved by the United States Food and Drug Administration: Prevalence of Related Drug Use

TL;DR: To review the labels of United States Food and Drug Administration‐approved drugs to identify those that contain pharmacogenomic biomarker information, and to collect prevalence information on the use of those drugs for which pharmacogenetic information is included in the drug labeling.
Journal ArticleDOI

Biomarker Qualification: Toward a Multiple Stakeholder Framework for Biomarker Development, Regulatory Acceptance, and Utilization.

TL;DR: Various types of biomarkers that can be useful in drug development and evidentiary considerations that are important for qualification are described.
Journal ArticleDOI

Integration and use of biomarkers in drug development, regulation and clinical practice: a US regulatory perspective

TL;DR: The US FDA organized workshops, issued guidances, established a voluntary submission process, developed online educational tools, and strives to ensure the integration of biomarkers into drug labels, for example, via the update of existing labels, or the inclusion of appropriate language in new drug labels.
