Tumorigenic MoA (Mechanism of Action) Scenarios of Fusion Genes for GAS6_NOC4L


check button To generate these tumorigenic scenario annotations, we implemented a deduction-first, retrieval-later computational framework. The pipeline first applies rule-guided reasoning across ten core mechanistic categories (M1–M10) derived from fusion gene biology to infer candidate mechanisms, tumorigenic scenarios, targeting points, and targeting backgrounds. To ensure empirical accountability, a governed Python workflow retrieves literature candidates via NCBI E-utilities and Europe PMC using tiered searches. Using JSON Schema-constrained LLM evidence judges (GPT-5.6 Luna and Terra), retrieved articles are evaluated for specificity and confidence without de novo PMID generation. This produces two distinct versions: a strict version restricted to high- or medium-confidence fusion-specific evidence, and an extended version incorporating broader gene-, pathway-, and contextual evidence.
* We have 10 tumorigenic mechanism categories of fusion genes as shown below.

Fusion Genomic Features for GAS6_NOC4L


check buttonFusionAI prediction of the potential fusion gene breakpoint based on the pre-mature RNA sequence context (+/- 5kb of individual partner genes, total 20kb length sequence) of In-frame fusion genes. FusionAI is a fusion gene breakpoint classifier based on convolutional neural network by comparing the fusion positive and negative sequence context of ~ 20K fusion gene data. From here, we can have the relative potentency of the 20K genomic sequence how individual sequnce will be likely used as the gene fusion breakpoints.

check buttonDistribution of six genomic regulatory feature tracks across a ±5 kb window centered on the fusion breakpoints. We input the breakpoint sequences into AlphaGenome and obtained predicted genome tracks at single-base-pair resolution for each modality by running a single forward pass over the reference sequence. Specifically, for each breakpoint, AlphaGenome processed and returned predicted track data across diverse modalities, which were then averaged across all tracks within each output type and visualized across the ±5 kb window. The left panel shows the 5'-gene breakpoint ±5 kb area, and the right panel shows the 3'-gene breakpoint area, with tracks grouped by category: chromatin accessibility (DNase-seq, ATAC-seq), active transcription (RNA-seq, CAGE), and chromatin binding (ChIP-Histone, ChIP-TF).
