Happy to share preprint of our lab's latest work led by talented PhD student, Luisa Quesada at @UVABME and @UVACancerCenter , applying a systematic multivariate analysis of chromatin complex dependencies to reveal Set1C/COMPASS as a #melanoma-enriched epigenetic vulnerability.
Systematic multivariate analysis of chromatin complex dependencies reveals Set1C/COMPASS as a melanoma-enriched epigenetic vulnerability biorxiv.org/content/10.64898…#biorxiv_cancer
We also report dependency on Set1C/COMPASS complex in melanoma. Via genetic perturbation, transcriptomics and single-cell analyses, we show that Set1C/COMPASS-dependent melanoma cells require this complex to maintain H3K4me3 and sustain MYC- and E2F-driven proliferative programs.
Together, our findings illustrate how integrative computational analysis and multivariate modeling can uncover mechanistically meaningful chromatin vulnerabilities in cancer.
Cancer cells have a dangerous superpower: the ability to change & adapt to resist treatment. UVA Biomedical Engineering Professor Mohammad Fallahi-Sichani is studying this "cell state plasticity" to develop therapies that could prevent resistance and metastasis. #ResearchInMotion
It was a pleasure and great fun attending the CMBE meeting, presenting updates from our lab work on Cell State Plasticity and AP-1 network , led by @UVABME PhD student, Yonatan Degefu.

🧬🧩 One network. Many cell states. Constant rewiring.
Mohammed Fallahi-Sichani @MFallahiSichani (UVA) shows how the AP-1 co-regulatory network organizes discrete, heterogeneous, and reconfigurable cell states.
Biology, built to adapt.

Excited to share our lab's latest work led by talented Yonatan Degefu, showing how cell state plasticity (in melanoma) is shaped by co-regulated, competitive, configurable interactions within the AP-1 transcription factor network.

Under MAPK inhibition, the network adapts; loss of JUND, down-regulation of FRA1, and up-regulation of cJUN, promoting a FRA2-High state that drives dedifferentiation (loss of MITF and SOX10) and MAPK inhibitor resistance.
These findings link the mechanistic logic of AP-1 network wiring to a well-known adaptive resistance phenotype in melanoma and show how model-guided perturbations can block this transition.
