Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Both Tumor Necrosis Factor Receptor Signaling Pathways Contribute to Mortality but not to Splenomegaly in Generalized Lymphoproliferative Disorder

Antibodies, 2014
The phenotypical consequences of a combined deficiency of the Fas-Fas Ligand (FasL) and one or both Tumor Necrosis Factor (TNF) signaling pathways were investigated. Mice, which expressed a non-functional FasL suffered from a pathological accumulation of

Thrombospondin and tumor necrosis factor

Kidney International, 1992
Progress in two main projects in my laboratory are discussed: (i) the study of the extracellular matrix/cell surface molecule thrombospondin (TSP); and (ii) the characterization of primary or immediate early response genes induced by tumor necrosis factor-α (TNF).

Biological Aspects of Tumor Necrosis Factor [PDF]

Immunobiology, 1986
Tumor necrosis factor (TNF) has been determined as an endogenous mediator for endotoxin-induced tumor necrosis. This macrophage product has been biochemically characterized and its protein structure defined by molecular cloning of the TNF gene. Experiments with antibodies to TNF demonstrated that TNF acts as an effector molecule of activated cytotoxic ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

Features of changes in the expression level of TNFα receptors and the functional response of cell lines upon stimulation with various doses of cytokine

Медицинская иммунология, 2023
TNFa is a pro-inflammatory cytokine that is signaled through type 1 (TNFR1) and type 2 (TNFR2) receptors. TNFR1 normally mediates apoptosis, cell survival, and cytokine secretion, while TNFR2 selectively mediates cell survival and cytokine secretion. But

From tumor‐centric to ecosystem‐based hypotheses in brain tumor research and care

Molecular Oncology, EarlyView.
Primary brain tumors, whether in adults or children, present a major challenge because of their dramatic prognosis and the ongoing lack of efficient therapeutic approaches. In recent years, a shift has occurred from tumor‐centric concepts to a more holistic view of these tumors as dynamic ecosystems.

Expression and associations of TRAF1, BMI-1, ALDH1, and Lin28B in oral squamous cell carcinoma

Tumor Biology, 2017
Tumor necrosis factor receptor–associated factor 1, an adaptor protein of tumor necrosis factor 2, is involved in classical nuclear factor (NF)-κB activation and lymphocyte recruitment. However, less is known about the expression and association of tumor

Targeting the Blood–Brain Tumor Barrier with Tumor Necrosis Factor-α

Pharmaceutics, 2022
The blood–brain tumor barrier represents a major obstacle for anticancer drug delivery to brain tumors. Thus, novel strategies aimed at targeting and breaching this structure are of great experimental and clinical interest.
