MetabolomicsAdaptation of gut microbiome and host metabolic systems to lignocellulosic degradation in bamboo rats

Bamboo rats (Rhizomys pruinosus) are among the few mammals that lives on a bamboo-based diet which is mainly composed of lignocellulose. However, the mechanisms of adaptation of their gut microbiome and metabolic systems in the degradation of lignocellulose are largely unknown. Here, we ...

MetabolomicsSystem Xc- exacerbates metabolic stress under glucose depletion in oral squamous cell carcinoma

OBJECTIVE: Emerging evidence suggests that glucose depletion (GD)-induced cell death depends on system Xc-, a glutamate/cystine antiporter extensively studied in ferroptosis. However, the underlying mechanism remains debated. Our study confirmed the correlation between system Xc...

MetabolomicsMethionine Intervention Induces PD-L1 Expression to Enhance the Immune Checkpoint Therapy Response in MTAP-deleted Osteosarcoma
Osteosarcoma (OS), a malignant bone tumor with limited treatment options, exhibits low sensitivity to immune checkpoint therapy (ICT). Through genomics and transcriptomics analyses, we have identified a subgroup of OS with methylthioadenosine phosphorylase (MTAP) deletion, which contributes to ICT r...

ProteomicsAberrant NAD+ metabolism underlies Zika virus-induced microcephaly
ZIKV-infection during pregnancy can cause microcephaly in newborns, yet the underlying mechanisms remain largely unexplored. Here, we reveal extensive and large-scale metabolic reprogramming events in ZIKV-infected mouse brains. We perform a multi-omics study comprising transcriptomics, proteomics, ...

ProteomicsUBA2-High Osteosarcoma Suppresses Immune Infiltration by Autophagy-Mediated MHC-I Degradation
Osteosarcoma (OS) responds poorly to immune-checkpoint blockade (ICB), and the molecular drivers of its immune-cold state remain unclear. Using multi-omics analyses, we identified an immune-cold OS subtype characterized by enrichment of protein SUMOylation and found the SUMO E1 subunit UBA2 as a key...
