Stephen John Sammut

You’re very welcome! Thanks for inviting me! Was so awesome spending time with you all and discussing science!! ❤️

Triple-negative breast cancer in biomed news this week🏥

So perfect timing to feature #ListerFellow @stephensammut.bsky.social 🤩He's hunting clinical biomarkers and using AI to predict treatment response from immune activation.

My poor laptop wishes I learned how to use the cluster earlier, but it’s sacrifice was not in vain! We learned some important things about the breast cancer tumor microenvironment, described in our paper published today:

Here's the 🧵

Multi-omic machine learning predictor of breast cancer therapy response - Nature Integration of pre-treatment tumour features in predictive models using machine learning could inform on response to therapy.

The first report of ML to integrate multi-omic data to generate a therapy response predictor. In a little over 3 years now cited >300 times in Web of Science! Incredibly proud @caldaslab.bsky.social and @stephensammut.bsky.social!!

thank you Chris and Andrew! 🙂

Thank you Ben!!!

Thank you!!!! 🙂🙂

Incredibly humbled and honoured to have been awarded the 2025 Research Prize from @thelisterinstitute.bsky.social. ❤️

🧬 We’re harnessing high-resolution molecular profiling + AI to uncover how cancer disables the immune system and find ways of restoring it. @icr.ac.uk

Lentiviral barcoding used to track the clonal growth of over 20,000 single-cell-derived clones in 110 xenografts from 26 patient-derived breast cancer xenograft models.

Beautiful work @nguyenlab.bsky.social!!

How does cancer affect motivation? Inflammatory cytokines hijack a brain circuit to cause apathy in cancer

A new Science summary spotlights a paper by CSHL’s Tobias Janowitz and colleagues that uncovers a neural circuit linking inflammation to reduced motivation in a mouse model of cancer cachexia. Check out the Science summary here: www.science.org/doi/10.1126/...

Single cell multi-omic whole genome sequencing and chromatin accessibility profiling reveals genome-epigenome coevolution in colorectal cancer Epigenetic alterations co-evolve with genetic mutations to drive carcinogenesis and treatment response. Resolving genome-epigenome coevolution requires accurate multi-omic single cell measurement. Her...

This is figure 5, which shows that aspirin promotes anti-metastatic immunity by releasing T cells from ARHGEF1-dependent suppression by TXA2.

Aspirin may enhance the immune response against cancer metastasis in mice, according to research published in Nature. The authors suggest that the findings could aid the development of effective anti-metastatic immunotherapies. https://go.nature.com/3F3GWOB 🧪
