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.

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. If you want to learn more about it, here is the link to the preprint: pubmed.ncbi.nlm.nih.gov/4127…
🧬🧩 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. #CMBE2026 #SystemsBiology

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. @UVABME @UVACancerCenter

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.
