Harnessing myeloid cell plasticity for cancer therapy
Abstract Myeloid cells have a multifaceted role in cancer, promoting tumor progression through angiogenesis, metastasis and immune suppression, as well as stimulating antitumor immunity. Traditionally, this dual functionality was attributed to cell heterogeneity, but it appears that myeloid cell plasticity is a more fundamental cancer trait.
Probing intratumoral metabolic compartmentalisation in a patient with fumarate hydratase-deficient renal cancer using clinical hyperpolarised 13C-MRI and mass spectrometry imaging | Communications Medicine
Abstract Fumarate hydratase-deficient renal cell carcinoma (FHd-RCC) is a rare and aggressive renal cancer subtype characterised by increased fumarate accumulation and upregulated lactate production. Renal tumours demonstrate significant intratumoral metabolic heterogeneity, which may contribute to treatment failure. Emerging non-invasive metabolic imaging techniques have clinical potential to more accurately phenotype tumour metabolism and its heterogeneity.
PARP inhibition generates enhanced CD8+ central memory T cells by transcriptional and metabolic reprogramming - Nature Immunology
Abstract CD8+ central memory T (TCM) cells provide stronger antitumor immunity than more-differentiated effector memory counterparts. Here we show that poly(ADP-ribose) polymerase (PARP) inhibition induces CD8+ TCM cells with superior memory by activating the SIRT-1–FOXO1 pathway and inducing metabolic and transcriptional switches through inhibition of enzymatic activity and enhanced PARP trapping.
