Drugs that control host cell pathways, including inflammation, tumor necrosis factor, interferons, and autophagy, can reduce the "cytokine storm" response to injury, control infection, and aid in cancer therapy.
In order to explore avenues to harness the therapeutic potential of antibody-cytokine fusions while decreasing potential toxicity, we compared bolus and fractionated administration modalities for two tumor-targeting antibody-cytokine fusion proteins based on human interleukin-2 (IL2) and murine tumor necrosis factor (TNF) (i.e., L19-hIL2 and L19-mTNF) in two murine immunocompetent mouse models of cancer (F9 and C51).
Although anti-TNFα agents have revolutionized the treatment of many inflammatory diseases, various concerns have been reported regarding the risks of cancer development, as well as acceleration of the progression of subclinical, preexisting malignancies.
Enrichment analyses of targeted mRNAs indicated transcriptional regulations and pathways including Rap1, Ras, MAPK, PI3K-Akt, TNF and Wnt signaling and pathways in cancer.
Registries have been central in clarifying the risk of infection and malignancy with anti-TNF therapy, despite the limitations of selection and channelling bias, incomplete case capture, unmeasured confounding, and the inability to infer causality.
There was nonlinear dose-response association (P<sub>nonlinearity</sub> for adiponectin = 0.01; P<sub>nonlinearity</sub> for leptin = 0.003).IL-6 (1.09, 0.94-1.25), TNF- α (1.65, 0.99-2.74), and resistin (1.28, 0.78-2.11) was not associated with risk of cancer.
In patients with CRC undergoing surgery, blood ADP and TNF-alpha concentrations were associated with the clinical stage of the cancer, likelihood of radical tumor excision, occurrence of nonsurgical postoperative complications, and long-term survival, which suggests the role of dysregulation in the endocrine function of adipose tissue in response to the neoplasmatic process.
Elevated levels of the pro-inflammatory cytokine tumor necrosis factor-α (TNFα) inhibit erythropoiesis and cause anemia in patients with cancer and chronic inflammatory diseases.
Because both peptide vaccination strategies and tumor-homing TNF fusion proteins are currently being studied in clinical trials, our study provides a rationale for the combination of these 2 regimens for the treatment of patients with cancer.
TNFα is a pleiotropic cytokine which fuels tumor cell growth, invasion, and metastasis in some malignancies, while in others it induces cytotoxic cell death.
Tumor necrosis factor (TNF)-α and its receptors (TNFR1 and TNFR2) regulate important cellular processes, such as apoptosis and cell survival, and the disruption of which can lead to cancer.
Targeting TRAIL (Tumor necrosis factor (TNF)-Related Apoptosis-Inducing Ligand) receptors for cancer therapy remains challenging due to tumor cell resistance and poor preparations of TRAIL or its derivatives.
Functional assays, qRT-PCR and microarray-based expression analyses were carried out to assess the effect of TNF-α on chemo-resistance, epithelial to mesenchymal transition (EMT), migration, invasion and cancer stem cell-like properties.
NF-κB-inducing kinase (NIK; also known as MAP3K14) is a central regulator of non-canonical NF-κB signaling in response to stimulation of TNF receptor superfamily members, such as the lymphotoxin-β receptor (LTβR), and is implicated in pathological angiogenesis associated with chronic inflammation and cancer.
CD30 is a member of the tumor necrosis factor family of cell surface receptors normally expressed in lymphocytes, as well as some lymphomas, but has been described in other malignancies.
These findings uncover a macrophage HIF/COX/TNF axis that links microenvironmental cues to macrophage phenotype, with important implications during inflammation, infection, and cancer, where hypoxia is a common microenvironmental feature and where cyclooxygenase and TNF are major mechanistic players.
