DOGMA-seq and multimodal, single-cell analysis in acute myeloid leukemia

Area of Science:

• Single-cell biology
• Cancer genomics
• Epigenetics

Background:

• Acute myeloid leukemia (AML) is a heterogeneous cancer requiring advanced diagnostic and stratification methods.
• Existing single-cell techniques like CITE-seq measure limited molecular modalities.
• Integrated genomics has improved understanding of cancer biology.

Purpose of the Study:

• To introduce DOGMA-seq, a novel multimodal single-cell technology.
• To highlight the potential of DOGMA-seq in studying complex cancers, specifically AML.
• To enable a comprehensive understanding of epigenomic, transcriptomic, and proteomic interactions in cancer.

Main Methods:

• DOGMA-seq simultaneously measures chromatin accessibility, gene expression, and cell-surface protein levels from individual cells.
• Builds upon previous bimodal single-cell techniques.

Main Results:

• DOGMA-seq provides a more comprehensive view of cellular states compared to bimodal methods.
• Enables simultaneous measurement of epigenomic, transcriptomic, and proteomic data.
• Facilitates detailed examination of molecular interplay within various cell types.

Conclusions:

• DOGMA-seq offers a powerful tool for dissecting the heterogeneity of AML.
• This technique can advance the understanding of cancer development and evolution.
• Potential to improve diagnosis, treatment, and patient stratification for complex cancers.
