Transcriptomic Analysis Service
Transcriptomic analysis focuses on the total RNA transcripts in a cell or tissues, allowing the researchers to analyze expression patterns of coding genes, discover alternative splicing forms, and identify non-coding RNAs. Our company provides high-quality sequencing and in-depth analysis services to help you quickly grasp gene expression information related to rare diseases.
Transcriptomics in Rare Disease
Transcriptomic analysis has broadened the view of gene expression in cells from patients with rare diseases on a genome-wide scale, rather than been restricted to a few genes. Abnormalities in some key genes acting as precursor factors may induce changes in a wide range of gene expression profiles, and the regulatory effects of non-coding RNAs on target genes are also being revealed. Therefore, transcriptomic analysis can provide unique gene expression patterns in rare patients. Combination of gene expression patterns and phenotypes will provide valuable clues for the development of more accurate diagnostic tools and targeted treatment.
- One-Dimensional Transcriptome
The routine transcriptome sequencing provides comprehensive RNA information in samples from patients with rare diseases. The differentially expressed genes obtained by comparison with normal controls are correlated with phenotypes to dig out the pathogenic genes and pathways. For example, the application of this technique has unraveled the transcriptional variants of immune cells in different cystic fibrosis (CF) patients.
- Two-Dimensional Transcriptome
In general, biological samples encompass a number of cell types, however, bulk RNA-seq does not have the ability to distinguish the particular expression signatures of these cells, nor can it differentiate between healthy and diseased cells, resulting in cellular heterogeneity being hidden. The advent of single-cell RNA-seq has greatly enriched the understanding of rare diseases. As exemplified by the case that single-cell RNA-seq has helped researchers determine the response of each immune cell to an intervention in patients with systemic autoinflammatory diseases.
- Three-Dimensional Transcriptome
In order to gain a more precise understanding of gene expression in different cells, it is necessary to dissect the transcriptional landscape from a higher dimension. The spatial transcriptome provides a platform to address this question. It is to be hoped that the spatial transcriptome detection of tissues from patients with rare diseases will be greatly helpful to understand the interactions between neighboring cells and find the specific location of abnormal cells with dysregulated transcripts.
The application of transcriptomic analysis in different dimensions provides a comprehensive exploration platform for the research and diagnosis of rare diseases. Our company has a mature diagnostics development system that provides you with a high-level bioinformatics team to support the transcriptomic analysis for rare disease.
