Biomarker and Target Discovery​


For disease research, a biomarker generally refers to a certain characteristic biochemical index in a general physiological, pathological, or therapeutic process that can be objectively measured and evaluated. By measuring it, the current biological process of the body can be known. With the development of high-throughput sequencing technology, new biomarkers can be used not only as indicators for disease diagnosis and later judgment, but also as therapeutic targets. Biomarkers play an important role in disease research: whether it is to clarify new biomarkers for improved diagnostic methods and drug development, or to verify existing markers in different types and stages of tumors, or to select the best target point transformed into preclinical research, and tumor markers have a great influence on the progress and practical application of tumor research.

Significance of Biomarker Data Analysis

The discovery of a disease-specific biomarker through various experiments and data analysis may be helpful for disease identification, early diagnosis and prevention, and monitoring during treatment. The search and discovery of valuable biomarkers have become an important focus of current research. The analysis of biomarkers by means of bioinformatics can provide data support for experiments to a large extent, thereby speeding up research progress and reducing research costs. With many years of data analysis experience, CD Genomics provides you with various types of biomarker and target discovery data analysis services. Through joint analysis of different omics data, gene expression analysis and interaction network analysis, it helps to identify drug-related targets in the process of disease occurrence and development.

Explore CD Genomics Biomarker and Target Discovery Solutions

CD Genomics provides customers with different types of biomarker and target discovery data analysis services. We provide different data analyses for different types of input raw data, and we will provide different biomarker identification schemes according to different research needs and original data.

Multi-omics Joint Analysis Solutions

A single-group analysis method can provide information on the biological processes of different life processes or disease groups compared with the normal group. However, these analyses often have limitations. Multi-omics joint analysis methods integrate information from several omics levels, provide more evidence for biological mechanisms, and dig out candidate biomarkers from a deeper level. We can provide high-quality multi-omics joint analysis, including: Transcriptome and Metabolome, Proteome and Metabolome, Microbiome and Metabolome, Transcriptome and Proteome, miRNA and mRNA, DNA Methylation-miRNA-mRNA, Genome and Metabolome, LncRNA and Metabolome, mRNA-Proteome-Metabolome, miRNA-mRNA and Protein, and so on.
