Synthetic chromosomes for 3D functional genomics: from principles to AI-guided design.

Area of Science:

• Genomics
• Molecular Biology
• Synthetic Biology

Background:

• The 3D organization of genomes is crucial for gene regulation, but its precise role in processes like promoter-activator interactions is unclear.
• Traditional methods face limitations in dissecting the complex interplay between genome structure and function.

Purpose of the Study:

• To review how synthetic genomics approaches address the ambiguity surrounding 3D genome organization's role in chromatin processes.
• To highlight the use of simplified, functional genomic systems to test structure-function relationships.

Main Methods:

• Synthetic genomics involves designing and assembling kilobase-scale genomic sequences into chromosomal segments.
• Creating simplified yet functional systems to isolate specific organizational principles.
• Utilizing AI-based sequence design in conjunction with synthetic genomics.

Main Results:

• Synthetic genomics overcomes experimental constraints by enabling controlled perturbations of genome structure.
• These approaches provide deep insights into the organizational logic governing genome function.
• Simplified systems in yeast and mammalian cells have been instrumental in these studies.

Conclusions:

• Synthetic genomics offers powerful solutions for understanding the functional implications of 3D genome organization.
• This field opens new possibilities for therapeutic genomic engineering by providing unprecedented insights.
