Thrilled to see my postdoctoral work published in @cellpress.bsky.social

OncoGAN generates simulated genomes to train genomic analysis tools —without the confidentiality risks of real genomes.

8/8 More info:

Alongside the OncoGAN models and pipeline, we’ve released 800 synthetic genomes spanning 8 tumor types!

A huge thank you to all the authors for their contributions to this work!!!

7/8 Is OncoGAN useful? Absolutely!

- We tested ActiveDriverWGS on synthetic genomes to see if it could detect the same driver genes as in real patient data, proving its value in refining algorithms and defining detection limits.

6/8 Is OncoGAN useful? Absolutely!

- We used OncoGAN simulations to augment DeepTumour’s training dataset (a tool for identifying tumor type based on somatic mutation patterns), showing performance improvements.

5/8 What does OncoGAN simulate?

- Copy number alterations (CNA) and structural variants (SV): This updated version successfully simulates CNAs and SVs.

4/8 What does OncoGAN simulate?

- Tumor heterogeneity (A): Simulating donors with varying mutational burdens and characteristics.

- Tissue-specific mutational patterns (B): Accurately modeling the genomic distribution of mutations and mutational signatures unique to different tumor types.

3/8 Why is OncoGAN necessary?

- Benchmarking: Since the ground truth of real cancer genomes is often unknown, evaluations typically compare methods, introducing potential bias. By generating open-access synthetic genomes with a known ground truth, OncoGAN helps improve and benchmark these tools.

2/8 Why is OncoGAN necessary?

- Improving data sharing: We have demonstrated that OncoGAN does not leak any private patient data from its training set, a crucial factor given the sensitivity of genetic information as protected health data.
