What is the minimum cellular input required for this integrated analysis, particularly concerning precious biological specimens?

Our protocols have been optimized for maximal sensitivity. While bulk tissue samples are generally preferred, we are capable of successfully generating high-quality data for the combined ATAC-seq and ChIP-seq analysis, which proves highly advantageous for valuable tissue or model-derived xenograft (PDX) samples.

Is this service capable of facilitating the identification of novel therapeutic targets if my specific TSG of interest lacks documented somatic mutations?

This scenario represents the primary intended application of the service. Our analysis will delineate the precise upstream factors responsible for its silencing. The subsequent inhibition of these regulatory elements is considered a potent strategy for TSG reactivation and establishes a novel pathway for therapeutic target identification.

Tumor Suppressor Chromatin Accessibility & Enhancer Activity Analysis Service

Creative Biolabs provides the critical functional analysis required for comprehensive mapping of the tumor suppressor gene (TSG) regulatory landscape. This service delivers a combined ATAC-seq and ChIP-seq analysis, facilitating high-resolution definition of both accessible chromatin regions and functionally active enhancer elements within a singular, rigorous framework. Investigators receive definitive evidence detailing epigenetic silencing mechanisms, a prioritized enumeration of actionable transcription factor targets, and a reconstructed gene regulatory network. These deliverables collectively serve to significantly accelerate preclinical target validation and advanced compound mechanism-of-action investigations.

Decoding Epigenetic Silencing of Tumor Suppressors via Chromatin and Enhancer Profiling

The inactivation of tumor suppressor genes constitutes a fundamental event in cancer pathogenesis. However, it is estimated that approximately 50% of TSG loss is attributable to epigenetic silencing, rather than genetic mutation. This phenomenon, frequently driven by aberrant super-enhancer (SE) programs, necessitates an advanced, functional analytical approach. Our service employs a multi-omics strategy to precisely decode this regulatory architecture. The resulting data not only permits the identification of epigenetically repressed TSGs but also pinpoints the upstream transcription factors that are driving the malignant phenotype.

What We Can Offer

Low-Input Specimen Expertise

Proprietary, high-sensitivity protocols are utilized to ensure robust data quality and analytical depth, even when processing challenging specimens. This capability encompasses FFPE blocks and primary tissue, thereby guaranteeing successful assay performance.
