As a leader in NGS-based cancer research, Creative Biolabs offers unrivaled single-cell whole-genome bisulfite sequencing services based on our advanced and powerful sequencing platforms.

Introduction of DNA Methylation

DNA methylation is an epigenetic modification that occurs by the addition of methyl (CH3) groups to the DNA molecule. It plays a key role in the regulation of gene expression without changing the gene sequence. In mammals, DNA methylation is associated with many key biological processes including genomic imprinting, X-chromosome inactivation, repression of transposable elements, aging, and carcinogenesis. Furthermore, DNA methylation is also associated with tumorigenesis. Increased evidence has reported aberrant DNA methylation is involved in the development and progression of human cancers. Tumor cells may display hypomethylation, leading to an increased oncogene activity which may be suppressed in normal cells. While tumor suppressor genes display hypermethylation which renders them inactive. Changes in DNA methylation in cancer can be considered as a promising target for the development of powerful diagnostic, prognostic, and predictive biomarkers.

Single-cell Whole Genome Bisulfite Sequencing

The identical individual organisms in almost all of the different types of cells have almost exactly the identical sequence of genome DNA. These DNA sequences may have different methylation modifications, thus making each type of cell, even every cell has its unique characteristics of gene expression, furthermore resulted in heterogeneity between different types of cells or between different cells of the same cell type. Single-cell whole-genome bisulfite sequencing combines bisulfite treatment and high-throughput sequencing technologies to detect genome-wide methylation at a single-cell level, making it possible to explore the epigenetic information of highly heterogeneous cells.

Single-cell bisulfite sequencing is an accurate and reproducible method for genome-wide methylation analysis. (Creative Biolabs Authorized)

Q&As

Q: What are the advantages of single-cell DNA methylation sequencing over bulk sequencing?

A: Single-cell DNA methylation sequencing offers higher resolution compared to bulk sequencing, which averages methylation signals across many cells. This high resolution allows for the detection of rare cell populations and specific epigenetic changes that may drive cancer progression.

Q: Can single-cell DNA methylation sequencing be applied to all cancer types?

A: Yes, this technique can be applied to a wide range of cancer types. It is particularly useful for studying cancers with significant cellular heterogeneity, such as breast cancer, lung cancer, and hematological malignancies.

Q: How does single-cell DNA methylation sequencing integrate with other single-cell technologies?

A: Integrating single-cell DNA methylation sequencing with other single-cell technologies, such as RNA sequencing and chromatin accessibility assays, provides a comprehensive view of cellular states. This multi-omics approach helps in understanding the complex regulatory networks driving cancer.

Q: What challenges are associated with single-cell DNA methylation sequencing?

A: Challenges include technical complexities in cell isolation, low DNA input, and the need for advanced bioinformatics tools to analyze large datasets. Despite these challenges, ongoing technological advancements are improving the efficiency and accuracy of this method.

Q: How does single-cell DNA methylation sequencing contribute to personalized medicine?

A: By providing detailed methylation profiles of individual cancer cells, this technique helps in identifying unique epigenetic markers for each patient. These markers can guide personalized treatment strategies, improving therapeutic outcomes and minimizing side effects.
