Hepatocellular carcinoma (HCC) is the third leading cause of cancer deaths worldwide. Effective treatment of HCC patients is hampered by the lack of sensitive and specific diagnostic markers of HCC. Alpha-fetoprotein (AFP), the currently used HCC marker, misses 30%-50% of HCC patients, who therefore remain undiagnosed and untreated. In order to identify novel diagnostic markers that can be used...

To determine whether known variants of the interleukin-1 (IL-1) and tumor necrosis factor (TNF) gene families are associated with severe manifestations of meningococcal disease, 276 white patients 4-70 years of age (median, 17 years) were genotyped. All patients had microbiologically proven Neisseria meningitidis infection; 39 died and 237 survived. A significant association (P<.001) was found ...

Obesity is associated with chronic low-grade inflammation perpetuated by visceral adipose. Other organs, particularly stomach and intestine, may also overproduce proinflammatory molecules. We examined the gene expression patterns in gastric tissue of morbidly obese patients with nonalcoholic fatty liver disease (NAFLD) and compared the changes in gene expression in different histological forms ...

Association between H. pylori infection, iron deficiency and iron deficiency anaemia has been described, but the mechanisms involved have not been established. We hypothesized that in H. pylori infected children increased gastric concentrations of IL-1β and/or TNF-α, both potent inhibitors of gastric acid secretion that is essential for iron absorption, are predictors for low blood concentratio...

BACKGROUND- Inflammatory cytokine interleukin-6 (IL-6), a possible risk factor for coronary heart disease, has an estimated heritability of >60%, but to date few genetic variants influencing IL-6 levels are known. METHODS AND RESULTS- We used the ITMAT-Broad-Care (IBC) HumanCVD disease BeadChip in the Whitehall II study (N=4911) and British Women's Heart and Health Study (N=3445) to identify si...

BACKGROUND Chronic pustular dermatoses are severe and debilitating autoinflammatory conditions that can have a monogenic basis. Their clinical features are, however, complex with considerable overlap. Null and missense mutations in the genes encoding interleukin (IL)-1 family (IL-1 and IL-36) anti-inflammatory receptor antagonist (Ra) cytokines can underlie the development of severe pustular de...

BACKGROUND The importance of the interleukin (IL)-1 cytokine family in inflammation and immunity is well established as a result of extensive in vitro and in vivo studies. In fact, much of our understanding of the in vivo importance of interleukin-1beta (IL-1B) is the result of research utilizing transgenic mice, such as overexpression or deficiencies of the naturally occurring inhibitor of IL-...

This study examined the ability of the recombinant human interleukin 1 receptor antagonist (IL-1ra) to block interleukin 1 (IL-1)-mediated experimental metastases from the A375M human melanoma. In vivo, IL-1ra administrated at concentrations > or = 200 times IL-1 significantly inhibited the increase in lung colonies induced by IL-1 in nude mice. The response to IL-1 was significantly inhibited ...

OBJECTIVE To assess changes of interleukin 6 (IL-6) and interleukin 1 receptor antagonist (IL-1ra) in serum, sputum, and drained pleural fluid of patients operated on due to lung cancer. METHODS Twenty-seven patients treated with lobectomy or pneumonectomy, including 14 with complications and 13 without complications, were analyzed. Serum IL-6 and IL-1ra concentration was measured before, at ...

The glucose transporter, GLUT4, redistributes to the plasma membrane (PM) upon insulin stimulation, but also recycles through endosomal compartments. Different Rab proteins control these transport itineraries of GLUT4. However, the specific roles played by different Rab proteins in GLUT4 trafficking has been difficult to assess, primarily due to the complexity of endomembrane organization and t...
