How do you handle highly degraded FFPE samples?

We utilize specialized DNA repair enzymes and high-sensitivity library preparation kits optimized for fragmented inputs. This ensures high-depth coverage and accurate variant calling even from older, suboptimal research tissue blocks.

Can your service detect viral oncoproteins interfering with the cell cycle?

Yes. Our platform includes specific algorithms to detect viral DNA integration and assess the transcriptional impact of proteins like HPV E6/E7 or HBV-X on host p53 and pRb pathways.

What is the advantage of systems biology modeling over standard NGS?

Standard NGS only identifies mutations; our modeling simulates how those mutations affect drug response in a dynamic environment. This provides a predictive view of potential resistance mechanisms and efficacy outcomes.

Genomic Alteration Assessment Services for Cell Cycle Dysregulation

Creative Biolabs delivers actionable genomic intelligence, transforming raw biological data into strategic therapeutic roadmaps by identifying molecular drivers of proliferation, from chromosomal translocations to acquired resistance mutations. We navigate the "cell cycle-death axis", where TP53 or RB1 mutations drive division while silencing apoptosis. Our platform integrates multi-omics data to provide granular evidence for combination therapies, such as pairing cell cycle inhibitors with DNA damage response (DDR) agents or BCL-2 antagonists, reducing clinical risk through precise molecular stratification.

The Molecular Drivers: Why Assessment Matters

The transition from quiescence to active division is governed by a cyclin-CDK relay, which, when compromised, drives unbridled proliferation. Genomic alterations, translocations, and overexpress of cyclin D1, while copy number variations involving CDK4 amplifications or CDKN2A deletions disable tumor suppression. Pathogens like HPV further hijack this system via E6 and E7 oncoproteins that degrade p53 and pRb. These events collapse the cell cycle-death axis, where TP53 mutations eliminate checkpoints and apoptosis, sustaining survival despite high replication stress and genomic instability.
