Deletion of Sufu in macrophages promotes inflammatory responses

ABSTRACT: Sepsis is a potentially life-threatening condition caused by the body's response to a severe infection. However, the pathogenesis of sepsis remains unclear. Here, we found that Suppressor of Fused (Sufu), a classical negative regulator of Hedgehog signaling, is downregulated in patients with sepsis and in murine peritoneal macrophages treated with lipopolysaccharide (LPS). Deletion of Sufu aggravated LPS-induced lung injury and lethality in mice, and augmented LPS induced proinflammatory gene expression in cultured macrophages. By RNA-seq transcriptome profiling, we identified Sufu as a negative regulator of the TLR-triggered inflammatory response.

Effect of SUFU overexpression and knockdown on gene expression profile in breast cancer epithelial cells

Project description:SUFU is a negative regulator of the hedgehog signaling pathway and its abnormal expression has been found in several human cancers, whereas the role of SUFU in the malignant development of breast cancer has not been fully elucidated. We performed RNA-seq to determine the impact of SUFU overexpression and knockdown on global gene expression profile in SKBR3 and HCC1954 cells. Our results show that sufu affects ferroptosis phenotype via modulating yap-dependent ACSL4 in breast cancer cells.

Liver transcriptome of an LPS infusion model for porcine sepsis

Project description:Sepsis is a life-threatening organ dysfunction resulting from a dysregulated host response to infection. This is best studied in humans and various mouse models, however finding sof these models to not always translate easy to the clinic. In order to improve this transfer, and because sepsis also plays a significant role in vetrenairy medicine, we use the pig as a model organism in sepsis research. We compare two modes of porcine sepsis iduction: fecal infusion and LPS infusion and also compare thse o wha we can find in mice

Extracellular acidity reprograms macrophage metabolism and innate responsiveness

Project description:Although organ hypofunction and immunosuppression are life-threatening features of severe sepsis, the hypofunctioning organs and immune cells usually regain normal functionality if patients survive. We tested the hypothesis that low extracellular pH (pHe) can induce reversible metabolic and functional changes in tissue macrophages. When compared with macrophages cultured at normal pHe, macrophages living in an acidic medium used less glucose and exogenous fatty acid to produce ATP. Lactate, glutamine, and de novo synthesized fatty acids supported ATP production by mitochondria that gained greater mass, maximal oxygen consumption rate, and spare respiratory capacity. The cells transitioned to a M2-like state, with altered immune responses to LPS and slightly decreased phagocytic ability, yet they regained basal energy production, normal mitochondrial function and pro-inflammatory responsiveness when neutral pHe was restored. Low pHe induces changes that support macrophage survival while rendering the cells less pro-inflammatory (more ‘tolerant’) and less able to phagocytose bacteria. Macrophage responses to low interstitial pH may contribute to the reversible organ hypofunction and immunoparalysis noted in many patients with sepsis.
