As one of the most abundant cell types in the TME, tumour-associated-macrophages (TAMs) can promote disease progression and resistance to therapy. Syndecan-3 (SDC3) is a cell-surface heparan sulphate proteoglycan expressed by TAMs, although its functional relevance in these cells remains unknown. Here, we demonstrated that pro-inflammatory cytokines drive the expression of SDC3 on the cell surface of macrophages. Genetic ablation of SDC3 in macrophages led to aberrant proliferation, adhesion and expression of CD40 and CD86 surface markers. Moreover, SDC3 defective macrophages exhibited distinctive gene expression patterns, leading to impaired tumour cell phagocytosis and increased tumour cell proliferation. Mechanistically, a decrease in the secretion of pro-inflammatory cytokines was observed in SDC3 KO macrophages, concomitant with impaired T cell effector functions. Additionally, a higher angiogenic capacity was observed in endothelial cells when co-cultured with macrophages deficient for SDC3, possibly mediated through an increased release of VEGFA, PECAM-1 and IL-8 by SDC3 KO cells.

Patients with propionic acidemia experience a range of complications, including life-threatening cardiac dysfunctions.

To gain insights into the metabolic alterations in propionic acidemia, we studied human induced pluripotent stem cell-derived cardiomyocytes generated from a patient with propionic acidemia with two pathogenic PCCA mutations (p.Cys616_Val633del and p.Gly477Glufs9*) and from a healthy individual. Using stable isotope-based metabolic flux analysis, we confirmed that the PCCA mutations lead to impaired propionyl-CoA carboxylase activity in human induced pluripotent stem cell-derived cardiomyocytes. In addition to being converted to propionylcarnitine, the accumulated propionyl-CoA can also be hydrolyzed to propionate and exported out of the cell, serving as a secondary \"pressure valve\" to regulate cellular propionyl-CoA levels. Interestingly, the deficiency of propionyl-CoA carboxylase was found to shift fuel metabolism from fatty acid oxidation to increased glucose metabolism human in induced pluripotent stem cell-derived cardiomyocytes from patients with propionic acidemia.
