Biological Aspects of Tumor Necrosis Factor [PDF]

open access: yesImmunobiology, 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 ...

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

open access: yesMolecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Role of Tumor Necrosis Factor in Tuberculosis

open access: yesBiomolecules
Tumor necrosis factor (TNF) is a key immunoregulatory cytokine with a dual role in the host response to Mycobacterium tuberculosis. While essential for granuloma formation, macrophage activation, and containment of latent infection, TNF can also ...

The hepatitis B virus X protein activates nuclear factor of activated T cells (NF-AT) by a cyclosporin A-sensitive pathway. [PDF]

open access: yes, 1998
The X gene product of the human hepatitis B virus (HBx) is a transcriptional activator of various viral and cellular genes. We recently have determined that the production of tumor necrosis factor-alpha (TNF-alpha) by HBV-infected hepatocytes is ...

PANoptosis in the pathogenesis of myelodysplastic syndromes

open access: yesMolecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Tumor Necrosis Factor-Alpha and Age-Related Pathologies

open access: yesАрхивъ внутренней медицины, 2020
Modern concepts about the «inflammaging» and the role of subclinical inflammation in various age-associated pathology are described in the review. Particular attention is paid to the tumor necrosis factor-α, a key cytokine that plays an important role in

Release of TNF-α during myocardial reperfusion depends on oxidative stress and is prevented by mast cell stabilizers [PDF]

open access: yes, 2003
Objectives: Our study sought to elucidate the role of oxidative stress for shedding of tumor necrosis factor-α (TNF-α) and for activating TNF-α-converting enzyme (TACE).

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

open access: yesMolecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Role of TNF–TNF Receptor 2 Signal in Regulatory T Cells and Its Therapeutic Implications

open access: yesFrontiers in Immunology, 2018
Tumor necrosis factor α (TNFα) is a pleiotropic cytokine which signals through TNF receptor 1 (TNFR1) and TNF receptor 2 (TNFR2). Emerging evidence has demonstrated that TNFR1 is ubiquitously expressed on almost all cells, while TNFR2 exhibits a limited ...
