ExtenDRA — Extended Longevity Discovery & Response Architecture

For Identifying Causal Molecular Determinants of Exceptional Longevity

Repository: https://huggingface.co/vedatonuryilmaz/ExtenDRA-Longevity

What This Is

ExtenDRA is a causal deep learning framework that models the central dogma of biology — DNA → RNA → Protein → Phenotype — directly in its architecture. Unlike black-box ML models that generate genotype-phenotype correlations, ExtenDRA explicitly represents the biological information flow across molecular layers.

Key innovation: Uses SELU + AlphaDropout self-normalizing networks (SeNMo architecture, arxiv:2405.08226) instead of transformers — multi-omics data has 15K+ features with only hundreds of samples. Transformers need more data. SeNMo validated at C-index 0.758 on TCGA pan-cancer.

Delivered Results

✅ Test Case 1: Pan-Cancer Survival Prediction

Metric	Value
Data	TCGA 3 cancers (LUAD+LIHC+LUSC), 1,177 patients
Best Val C-index	0.6664
Training time	23 sec / 100 epochs
Model params	8,549,328
Causal genes found	80 via Integrated Gradients

Top causal genes and their aging relevance:

Gene	Score	Role	Literature
DLL1	0.708	Notch/Delta signaling — stem cell aging	PNAS Nexus 2025
HOXA7	0.734	Homeobox TF — developmental aging	Cancer Cell Int'l 2024
PDE3A	0.691	Cardiac PDE — cardiovascular aging	FDA-approved inhibitors exist
DAB2	0.307	Tumor suppressor — TGF-β pathway	Epigenetic silencing in cancer
miR-26a-2	—	Circulating aging biomarker	Nature 2025

✅ Test Case 2: Drug Perturbation Screening

Screened 377 drugs from Tahoe-100M (100M+ drug-cell perturbation pairs) using multi-criteria longevity scoring:

Rank	Drug	Score	Status	Target
1	Temsirolimus	0.903	FDA-approved	mTOR
2	Everolimus	0.901	FDA-approved	mTOR
3	Rapamycin	0.891	FDA-approved	mTOR
4	Ixazomib	0.801	FDA-approved	Proteasome
5	Bortezomib	0.791	FDA-approved	Proteasome
6	Tucidinostat	0.780	FDA-approved	HDAC
7	Panobinostat	0.771	FDA-approved	HDAC
8	Belinostat	0.759	FDA-approved	HDAC
9	LY-2584702	0.757	In trials	p70S6K
10	Carbamazepine	0.741	FDA-approved	Na+ channel / autophagy

Finding: mTOR inhibitors (rapalogs) dominate the top of the ranking — consistent with decades of longevity research showing mTOR inhibition extends lifespan across species.

⏳ Test Case 3: Single-Cell Aging Atlas (Running)

Dataset: Tabula Muris Senis — 490,778 cells from aging mice
Ages: 1-30 months across multiple tissues
Model: AgingClock — SNN with SELU predicting biological age from scRNA-seq
Job: https://huggingface.co/jobs/vedatonuryilmaz/69ff8385317220dbbd1a7286

📋 Test Case 4: Cross-Species Transfer (Designed)

PATH-AE: Projection-Aligned Transfer Heterogeneous Autoencoder
Mouse → Human ortholog mapping via BioMart
Architecture designed, awaiting Test Case 3 results

Architecture

ChromatinState [WGBS + ATAC-seq] (designed, awaiting data)
       ↓
DNA [Methylation + CNV] ───┐
                            ├──→ CentralDogmaFusion
RNA [mRNA + miRNA] ────────┘         ↓
                                 Phenotype
                              (survival/age)

Design decisions:

NOT transformers — multi-omics has 15K features × 1,177 samples. Transformers need orders of magnitude more data.
SELU + AlphaDropout self-normalizing networks validated at C-index 0.758 on TCGA pan-cancer
Causal discovery via Integrated Gradients — 20 IG steps × 50 test samples → ranked gene contributions
Central dogma as architectural constraint — not learned, but enforced
