Omics Technologies in Biomarkers Discovery and Validation

Biomarkers play a critical role in disease diagnosis and treatment, especially for the early detection of cancer, to enable screening of asymptomatic populations. Recent omics technologies, such as Transcriptomics, genomics and proteomics approaches besides Metabolomics are accelerating the rate of biomarker discovery. The incorporation of techniques like microarray data analysis, computational biology, data mining methods, Transcriptomics and profiling techniques are playing a crucial role in the validation of biomarkers. Since the Human Genome Project was completed in April 2003, genome-wide association studies (GWAS) have contributed toward a greater understanding of the genetic basis of complex diseases and advances in high-throughput technologies. This has enabled researchers to rapidly map the genome of vertebrates, invertebrates and pathogens through cost-effective methods.
