A new technique called TaDRIM-seq enables efficient profiling of chromatin-associated RNAs and RNA-RNA interactions across various genomic regions.
TaDRIM-seq reflects the simultaneous mapping of chromatin-associated RNAs (caRNAs) and RNA-RNA spatial interactions within nuclei, facilitating insights on their role in gene regulation and genome organization.
The research involved several authors from various institutions, acknowledging the contributions made to the development of TaDRIM-seq.
The study was published and made publicly available as of 2024, showcasing recent advancements in the field of RNA interaction studies.
The research was conducted using mammalian cells and plants, particularly focusing on K562 cells and rice.
This research aimed to overcome limitations present in existing methodologies for studying RNA interactions, enhancing the efficiency and resolution of RNA-DNA and RNA-RNA interaction mapping.
TaDRIM-seq involves crosslinking, antibody binding, tagmentation, RNA ligation, and next-generation sequencing processes to obtain detailed interaction maps.
"TaDRIM-seq is an effective multi-omic technique...providing a comprehensive caRNA map in animal cells and plants."
"...TaDRIM-seq enables the concurrent detection of two types of caRNA interactions within the same experiment by designing a DNA adapter for caRNA-DNA capture and a bridge linker for RNA-RNA detection."
"The results suggest...dynamic coordination of the 3D genome during day/night cycles."
