We are a group of microbiologists, bacterial and cancer biologists, and computational scientists dedicated to deciphering the role of microbes in cancer.

Our work with the @CJohnstonLab1 lab out today @Nature demonstrating the intratumoral microbiota impacts spatial, cellular and transcriptional heterogeneity in human cancer. Monster tweetorial below from Chris.
Finally, two papers out within a day of each other from the @BullmanLab and @CJohnstonLab1 relating to the intratumoral microbiota, today in @Nature ( https://t.co/crU4Azm6Ck) and yesterday in @CellReports ( https://t.co/ESITlazD6h). 🧵below to those interested!

New from the Bullman Lab in Cancer Cell! Tumor-infiltrating bacteria, including Fusobacterium, disrupt cell-cell contacts & trigger quiescence, uncovering a pathway of bacteria-induced therapy resistance 🔗 https://t.co/Bd3L6izEAl Thanks to @MDAndersonNews, @FredHutch, @UTEPnews
Bacteria can impact cancer progression and treatment. A new study shows how a particular bacteria can induce a reversible state in cancer epithelial cells, which allows tumors to evade the immune system and resist chemotherapy: https://t.co/wSE0NecCYF

These findings add to the increasing evidence that cancer is not driven solely by DNA mutations. 🧵

I’m happy to share our latest work on tumour necrosis! During my time in the @megeblad lab, we found that tumour necrosis is not a passive phenomenon secondary to tumour growth, but an active phenomenon driven by neutrophils and NETs! Thread below: (1/13) https://t.co/Tr0nHLXRzz

What exactly does "Fusobacterium nucleatum" refer to? It depends who you ask (and when you asked them). Our new perspective on taxonomy and naming challenges @GutMicrobes, proposing a genomics-based framework for Fusobacterium species designations. 🦠

The F. nucleatum group (sensu lato) is historically composed of four subspecies (F. nucleatum subsp. animalis, F. nucleatum subsp. nucleatum, F. nucleatum subsp. polymorphum, F. nucleatum subsp. vi...

If your stack of images is full of defects, don't panic! InterpolaAI, a deep learning-based optical flow method, will fix issue tears, photobleaching and sticking artifacts for improved 3D imaging. Read our paper in Nature Methods: https://t.co/LIpzl3heoB

Second paper on HMGA2 mediated basal identity in #PancreaticCancer from Sita Kugel @fredhutch. This one is an elegant mechanistic dissection of the multi step cascade through which HMGA2 overexpression orchestrates basal lineage state: https://t.co/vUgXCW6vNL
The first example of how the impressive scRNA seq data set in #PancreaticCancer (collated by @NinaSteele17) can be leveraged for hypothesis generation & testing is now published in @CCR_AACR. Sita Kugel @fredhutch demonstrates that HMGA2 is a reliable marker of the basal subtype

Powerful new story from the Srivastava Lab @sriv4000
Modulating AP-1 enables CAR-T cells to establish an intratumoral PD-1+ Tcf1+ stem-like reservoir and overcomes resistance to PD-1 axis blockade https://t.co/bdDVFps5Uo

It was a quite a transformative experience to attend the inaugural Microbiome Accelerator from NatureAwards and @seedhealth in London last year. Highly recommend entrepreneurial microbiome scientists to apply for the 2025 cycle!

Bacteria that naturally infect solid tumours can now be engineered to deliver anticancer therapies, making microbial cell therapy a viable prospect.

Beautiful work on Fusobacterium and CRC by @JessicaRQueen1, Drewes & Sears teams. “Biofilms were prevalent on colon tumors visualized in 68.8% ….more frequently observed on right-sided tumors (91.7%)”. https://t.co/UjQyFXfaAF

1/ Congrats to Sunita Keshari and all authors on our publication, where we interrogated tumor microenvironment (TME) remodeling induced by neoantigen (NeoAg) cancer vaccines and αPD-1, αCTLA-4 ICT, uncovering a more effective NeoAg vaccine-based combo preclinical therapy.

Four years after the 2020 Method of the Year (“spatially resolved transcriptomics”), @naturemethods has now nominated “spatial proteomics” as the 2024 Method of the Year. H/T @RongFan8 (spatial guru!)
