Background:

Topologically Associating Domains (TADs) are crucial for genome organization and function.
Identifying TADs is essential for studying immune system dynamics and chromosomal structure.
Existing methods for TAD identification can be computationally intensive.

Purpose of the Study:

To introduce EmbedTAD, a novel computational method for identifying TADs.
To leverage graph embedding and clustering for efficient TAD detection from high-resolution Hi-C data.
To validate EmbedTAD's performance in detecting TAD rearrangements and boundary protein enrichment.

Main Methods:

Utilized NetMF, a low-resource graph embedding technique.
Employed HDBSCAN for clustering embeddings to define TAD regions.
Applied EmbedTAD to high-resolution Hi-C data, including during T-cell differentiation.

Main Results:

EmbedTAD successfully identified TAD rearrangements during T-cell differentiation.
The method differentiated between active and inactive cells based on TAD structures.
EmbedTAD demonstrated reproducibility by recovering TADs found in PLAC-seq data.
Detected distinct ChIP-seq signals (CTCF, RAD21, SMC3) at identified TAD boundaries.

Conclusions:

EmbedTAD provides a reliable and computationally efficient method for TAD identification.
The tool outperforms existing state-of-the-art methods in TAD detection.
EmbedTAD facilitates the study of genome organization and its relation to cellular processes.
