What is the advantage of 3D linking over nearest-gene analysis?

Nearest-gene analysis is often misleading; studies show up to 40% of enhancers skip the closest promoter to regulate a distal gene. Creative Biolabs uses physical mapping to confirm actual interactions.

How do you validate the functionality of the identified enhancers?

We integrate eRNA transcription levels and DNA methylation correlation to ensure that the identified elements are actively participating in transcriptional regulation.

What bioinformatic support do you provide?

We provide a full suite of services, from raw data processing to high-level network inference, transcription factor (TF) footprinting, and pathway enrichment analysis.

Regulatory Element-Gene Linking & Cistrome Integration Service

Creative Biolabs provides a sophisticated solution for identifying the non-coding drivers of tumor progression. Standard genomic sequencing often fails to explain the transcriptomic heterogeneity of cancer because it ignores the distal regulatory elements (DREs) that control gene dosage. Our service assists your project by establishing definitive, physical, and functional links between these "silent" enhancers and their target oncogenes. By characterizing the cistrome, we allow you to pinpoint the exact regulatory "switches" that, when dysregulated, lead to therapeutic resistance or lineage plasticity.

Introduction to Regulatory Element-Gene Linking

Cancer is a disease of dysregulated gene expression driven by a remodeled epigenomic landscape. Scientific evidence has established that "transcriptional addiction" in tumors is maintained by super-enhancers and core regulatory circuitries. Creative Biolabs systematically maps these distal regulatory elements (DREs) and their target genes, providing a comprehensive view of the cancer cistrome and its 3D architectural constraints. This integrative approach is essential for identifying the master drivers of tumorigenesis and supporting the next generation of precision oncology.

Our Solution: A Holistic Cistrome Integration Service

Creative Biolabs delivers an end-to-end suite of epigenomic mapping capabilities designed to decode complex gene-regulatory networks. Our offerings include:

Integrated Cistrome Mapping

We provide comprehensive identification of transcription factor binding sites across the genome, coupled with detailed chromatin state analysis. This allows researchers to define the active regulome with exceptional precision and clarity.

High-Resolution Enhancer-Promoter Linking

Our specialized 3D genomic assays bypass the inherent limitations of linear genomic distance. We physically connect distal elements to their actual target genes, ensuring accurate mapping of complex regulatory interactions.

Super-Enhancer and Hub Discovery

We identify high-density regulatory clusters and super-enhancers that drive core cell identity. Mapping these "powerhouses" reveals the essential nodes that maintain oncogenic potential and dictate tumor behavior in various models.

Transcriptional Circuitry Reconstruction

Utilizing advanced bioinformatic modeling, we define the master regulators and feed-forward loops sustaining phenotypes. This reconstruction provides a holistic view of the transcriptional control room governing cancer cell survival.

Custom Multi-omic Synthesis

We offer seamless integration of ATAC-seq, ChIP-seq, and RNA-seq data. This synthesis provides a unified functional readout, bridging the gap between physical chromatin states and actual gene expression levels.

Workflow

Creative Biolabs has engineered a robust, multi-stage pipeline designed to translate raw biological samples into comprehensive regulatory maps.

Publication

This study investigates the epigenetic drivers of breast cancer lung metastasis through integrated analysis of histone modifications and transcriptomes in metastatic and non-metastatic cell lines. It reveals widespread promoter and enhancer reprogramming, identifies numerous gained super-enhancers in metastatic cells, and uncovers a tightly cooperative network of master transcription factors, including LMO4, that regulate metastasis-associated pathways and correlate with patient prognosis.

Why Choose Us?

Creative Biolabs stands at the forefront of epigenetic research by combining "wet-lab" excellence with "dry-lab" innovation. We differentiate between mere "genomic proximity" and true "biological functionality" by utilizing proprietary benchmarks and published evidence on enhancer-promoter communication. Our platform is uniquely designed to identify super-enhancers, large clusters of transcriptional activity that drive oncogenic states, and enhancer RNAs (eRNAs), which serve as real-time readouts of enhancer activity. Unlike standard services, we provide a hierarchical view of the cistrome, allowing you to prioritize the most potent regulatory hubs for therapeutic intervention.
