Meta-analysis of gut microbiome reveals patterns of dysbiosis in colorectal cancer patients
Introduction. Colorectal cancer (CRC) is a malignant tumour in which dysbiosis of the gut microbiome is a contributing factor in the development of cancer. However, the species composition and species-specific changes in the gut microbiome related to CRC still require comprehensive investigation. Hypothesis. There is a significant difference in gut microbiome between CRC patients and healthy individuals. Aim. The microbiome-based association test methods are used for the association between the microbiome and host phenotypes, and linear discriminant analysis effect size (LEfSe) analysis is...

How does other types of microbe like fungi influence tumor-promoting role of Fusobacterium nucleatum?

Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
Overall, our work shows that Candida doesn’t just trigger immune pathways — it rewires epithelial metabolism to create an environment that benefits the fungus and weakens host defenses.
100
Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
Blocking GOT1 with a specific inhibitor reduced epithelial damage and inflammatory cytokine release. This means the pathway is not just a marker — it’s functionally relevant. Targeting host metabolism may offer new ways to manage mucosal fungal infections.
100
Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
We confirmed that GOT1 and pyruvate carboxylase are upregulated during infection, and TCA metabolites (citrate, malate, α-ketoglutarate, etc.) decrease. This aligns perfectly with the alternative pyruvate shunt predicted by our modelling.
100
Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
In mice, reducing glycolysis with 2-deoxyglucose actually reduced fungal burden and weight loss, whereas adding extra glucose made disease worse. This contrasts with macrophages and systemic candidiasis, showing that oral epithelial infections follow different metabolic rules.
100
Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
One of the most interesting outcomes: Sugar availability dramatically changes infection outcomes. High glucose → worse epithelial damage Alternative hexoses (galactose/fructose) → impaired cytokine production ❗Metabolism and the nutritional environment really matter.

Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
Our team used a multi-disciplinary approach combining: • transcriptomics • NMR-based metabolomics • genome scale metabolic modelling • epithelial infection assays • a mouse model of oropharyngeal candidiasis • human patient biopsies This gave us a full view of the epithelial metabolic shift.
110
Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
Why is this important? 🤔 Because this shunt helps determine the fate of infected cells, influencing: • their ability to mount an immune response • how much damage the fungus can cause • the overall inflammatory landscape of the mucosa
110
Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
Even more striking, we identified a previously unrecognized metabolic route activated during infection: a GOT1-dependent TCA cycle shunt. This pathway diverts carbon away from the normal TCA cycle, producing aspartate and ammonia instead.
100
Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
Our key finding: C. albicans forces epithelial cells to shift into aerobic glycolysis — a fast but inefficient way of generating energy, similar to the “Warburg effect" observed in cancer cells. This happens early in infection and shapes how cells survive and respond.
100
Aize Pellón Rodríguez @aizepellon.bsky.social · 05/02/2026
Most people carry C. albicans in their mouth without issues. But when immunity weakens or the oral niche is altered, this fungus can overgrow and cause oral candidiasis. Despite how common it is, we still lack a full picture of how epithelial cells react metabolically when infected.

We just published a new paper in Science Advances, where we uncover how #Candida albicans reprograms the metabolism of oral epithelial cells during infection. As first and corresponding author, I’m excited to share what we found — and why it matters. #Skytorial #Immunometabolism #MedMycoSky
