Comprehensive Functional Mapping of Tumor Suppressor Gene
Tumor suppressor gene profiling services (TSG Profiling) analyze the multi-faceted inactivation of the cell's "brakes," moving beyond simple sequencing to capture the full spectrum of loss-of-function events. The inactivation of TSGs is fundamental to cancer research, as evidenced by the Knudson two-hit hypothesis and early MMCT functional studies. Our service integrates next-generation sequencing with epigenetic and structural analyses to definitively map the functional status of these critical genes, accelerating the identification of synthetic lethal targets and paving the way for effective oncology research strategies.

Highlights
Multi-Modal Resolution
We are one of the few providers that integrate SNV, LOH/CNV, and promoter methylation data streams to deliver a single, definitive TSG functional status score, ensuring 100% functional TSG status resolution.
Addressing the Epigenetic Paradox
We specifically target and quantify the complex epigenetic network (methylation, histone modifications) that silences TSGs like BRCA1 and CDKN2A, which is critical for identifying targets for reversible epigenetic strategies.
Unparalleled Heterogeneity Capture
Our high-resolution CNV mapping and proprietary algorithms are designed to detect subclonal TSG losses within heterogeneous tumor populations, crucial for accurate prognosis and drug resistance mechanism prediction.
Validated Science
Our methodology is rooted in the foundational principles of cancer genetics, including the Knudson two-hit hypothesis, and validated against the functional complementation insights established.

Actionable Epigenetic Insights
The utilization of Creative Biolabs' services has considerably advanced the investigation into epigenetic cancer therapeutics. Specifically, the single-base resolution methylation analysis provided unambiguous differentiation between hypermethylated and unmethylated MGMT promoter statuses. - Dr. A**o -
Comprehensive Functional Score
Using Creative Biolabs' services in our research has significantly improved our ability to interpret complex genomic data. The integrated TSG functional status score simplifies data interpretation, especially for genes where we needed to account for gain-of-function mutations alongside traditional LOF. - Dr. L**h.
FAQs
Why is multi-modal profiling necessary? Can't standard whole-exome sequencing (WES) detect TSG loss?
Standard WES is excellent for point mutations, but it often misses the "silent killers" - TSGs inactivated solely by promoter hypermethylation or complete loss of an allele. Our integrated approach is necessary because a TSG like BRCA1 might appear structurally normal in WES but be functionally silenced by epigenetic modification.
How does Creative Biolabs' TSG Functional Status Score help me prioritize targets?
The Score is a comprehensive metric that weighs the severity and type of inactivation. It provides a clear, quantitative measure of the overall oncogenic drive from TSG loss, allowing your team to rapidly prioritize targets with the highest therapeutic leverage.
