Tumor necrosis factor (TNF)-alpha causes insulin resistance on glucose uptake in fetal brown adipocytes. We explored the hypothesis that some effects of TNF-alpha could be mediated by the generation of ceramide, given that TNF-alpha treatment induced the production of ceramide in these primary cells. A short-chain ceramide analog, C2-ceramide, completely precluded insulin-stimulated glucose upt...

INTRODUCTION Sarcoidosis is a multisystemic disease of unknown etiology. Genetic factors play a considerable role in the onset of the disease. Tumor necrosis factor alpha (TNF-a) is a proinflammatory cytokine which plays an important role in the pathogenesis of the disease and the formation of granuloma by regulating cellular proliferation and apoptosis. OBJECTIVE The aim of this study was to...

BACKGROUND & OBJECTIVES Tumour necrosis factor-alpha (TNF-α)- 308 promoter gene polymorphism has been shown to be associated with several autoimmune disorders and infections such as tuberculosis. There is no study on TNF-α gene polymorphism in Takayasu's arteritis (TA) till date. We aimed to study this polymorphism in TA, a granulomatous vasculitis, probably triggered by Mycobacterium tuberculo...

Background: Type 1 diabetes mellitus (T1DM) is a chronic, immune-mediated disease characterized by the destruction of insulin-producing β cells in pancreas. This study investigated influence single nucleotide polymorphisms (SNP) tumor necrosis factor (TNF-α) –308 G/A (rs1800629,) on T1DM patients. Method: The was included 75 patients and 25 healthy subjects. SNP–308 TNF-α gene detected using po...

CONTEXT Sepsis, organ failure, and shock remain common among patients with moderate to severe burn injuries. The inability of clinical factors to identify at-risk patients suggests that genetic variation may influence the risk for serious infection and the outcome from severe injury. OBJECTIVE Resolution of genetic variants associated with severe sepsis following burn injury. PATIENTS A tot...

Polymorphisms in tumor necrosis factor alpha (TNF-α) gene are emerging as key determinants of gastric diseases. The TNF-α(-308) (G/A) and TNF-α(-238) (G/A) single-nucleotide polymorphisms SNPs are the most extensively studied. However, all these studies are conducted in Caucasian and Asian populations. Thus, for the first time in Africa, we sought to investigate whether polymorphisms in TNF-α g...

OBJECTIVES To evaluate the association between the genetic polymorphism of the tumor necrosis factor-alpha (TNF-α) gene and the development of sepsis and septic shock in Thai pediatric patients and to investigate the clinical impacts of TNF-α polymorphisms in this population. METHODS To perform this genetic association study, a prospective analysis of pediatric patients (age < 18 years) with ...

Plasma levels of tumor necrosis factor-alpha (TNF-alpha) are significantly raised in malaria infection and TNF-alpha is thought to inhibit intestinal iron absorption and macrophage iron release. This study investigated putative functional single nucleotide polymorphisms (SNPs) and haplotypes across the major histocompatibility complex (MHC) class III region, including TNF and its immediate neig...

Abstract Introduction Higher tumor necrosis factor-alpha (TNF-α) gene expression has been revealed in the peripheral blood monocytes across menstrual cycle patients with primary dysmenorrhea (PDM) than unaffected control. Sleep quality is affected by environmental factors, endocrine function abnormalities and genetic factors. The aim of this study was to evaluate effect TNF-α G308A polymorphism...

Background: Idiopathic pulmonary fibrosis (IPF) is characterized by a chronic inflammatory process and abnormal wound healing. Tumor Necrosis Factor alpha (TNFα) is considered to play a key role in fibroblast proliferation and increased collagen synthesis. It appears that there is a genetic predisposition to IPF. The genetic associations of TNF-α with IPF have been reported in different cohorts...
