🚀 Excited to share our latest research! We developed GRITIC, a novel method for timing genomic gains using bulk WGS data. Our findings reveal non-parsimonious evolution and increased chromosomal instability post-genome doubling in tumors. aacrjournals.org/cancerdisco…#cancergenomics
📢Our latest preprint! We present GRITIC, a generic method to time complex copy number gains from WGS data. We apply GRITIC to 5656 tumors to paint the landscape of complex CNA evolution pan-cancer, focussing on genome-doubled primaries and mets. biorxiv.org/content/10.1101/…
GRITIC is now available on GitHub. It requires allele-specific copy number, SNV calls and (optionally) subclonal SNV clustering information. Try it out:

Registration is now open for our Somatic Evolution and Tumour Microenvironment (SETM) symposium, where discussions and talks will focus on improving our understanding of cancer evolution.

For years, we’ve looked for recurrent copy number changes in cancer but lacked a pan-cancer view of the processes that give rise to these events. We've collaborated on two @Nature studies into the mechanisms underlying aneuploidy and chromosomal instability (1/4)
@DrewsRM et al. deconstructed chromosomal instability in 6,335 cancers to discover 10 pan-cancer and 7 cancer-type-enriched signatures. CIN signatures associated with known aetiologies - replication stress, mis-segregation and impaired recombination: nature.com/articles/s41586-0… (3/4)
These signatures are the first step in cataloguing the processes that culminate in the copy number states we observe in tumors. As with mutational signatures, these studies have set a foundation for the community to build on their methods and discover CIN aetiologies. (4/4)
Total mRNA expression in tumor cells is an important, but so far elusive, biomarker. This elegant piece of team science establishes the mathematical relationships between copy number, purity and gene expression in tumor cells. Proud to have been part of this great team!
Very excited to share our paper in Nature Biotechnology today! Huge amount of work by @ShaolongCao@sxj307@JenniferWangMD et al! It is amazing to work with many experts across cancers. Every cancer tells its own story and our metric TmS can quantify it! go.nature.com/3mn0CAr
Tumor samples vary in purity and ploidy, both of which confound DNA methylation measures from bulk sequencing. We developed CAMDAC to clean up this signal. Here's our extended preprint with new insights from applying CAMDAC to TRACERx lung RRBS data: biorxiv.org/content/10.1101/…
Fantastic work linking somatic mutation rates with lifespan across mammalian species, allowing us to make sense of the lack of relationship between body size and cancer incidence.
Incredibly excited to share our paper ‘Somatic mutation rates scale with lifespan across mammals’ now published @nature.

We are delighted to announce Dr. Jonas Demeulemeester as a new group leader in the @VIBLifeSciences Center for Cancer Biology as of today where he will establish his Laboratory of Integrative Genomics. Welcome @zeunas at @vib_ccb!
🎉We’ve officially released ASCAT version 3! You can now run ASCAT on sequencing data with improved copy number calling and brand-new quality control metrics. See the full list of features and download ASCAT v3 here: github.com/VanLoo-lab/ascat
Excited to share our new paper in @NatureGenetics! Can a mutation really hit the same place twice? We found biallelic mutations across 2,658 cancer genomes that contradict the famous infinite sites assumption and highlight the processes behind them: nature.com/articles/s41588-0…
