Polyunsaturated fatty acids (PUFAs), reported to be cytotoxic at micromolar concentrations for cancer cells in vitro and in vivo, are currently being tested in clinical trials as anti-cancer agents. This study has shown that seven PUFAs all inhibited the growth in vitro of three pancreatic cancer cell lines and the HL-60 leukaemic cell line. Five PUFAs(More)
A total of 98 breast aspirates from patients with breast cancer have been fixed and stained for oestrogen receptors using the Abbott ERICA kit. In a preliminary series of 41 aspirates, cytochemical staining index (% cells staining x mean intensity) related to the receptor concentration determined biochemically on a subsequent biopsy with a correlation(More)
In addition to various roles in membrane structure and metabolism, polyunsaturated fatty acids have effects on signal transduction and on the regulation of gene expression. Eicosapentaenoic acid (EPA) is an omega-3 fatty acid which is known to induce cell cycle arrest and apoptosis in pancreatic tumour cells. NFkappaB is a key transcription factor(More)
The acute phase protein response (APPR) and peripheral blood mononuclear cell-derived inflammatory cytokine production was assessed in patients with advanced pancreatic cancer and age-matched healthy volunteers. We examined the relationship between the APPR, cytokine production and survival in these patients. Forty-two patients with pancreatic cancer(More)
Patients with pancreatic cancer frequently demonstrate symptoms such as weight-loss and muscle wasting and have clinical evidence of a systemic inflammatory response. Such effects may be mediated by pro-inflammatory cytokines derived from tumor cells. The production of interleukin-6 and -8 by pancreatic cancer cell lines and the influence of other cytokines(More)
Kupffer cells are the resident macrophage population of the liver and have previously been implicated in the pathogenesis of hepatic ischemia-reperfusion injury (IRI). Kupffer cells are the major site of expression of hepatic heme oxygenase-1 (HO-1), which has been shown to have anti-inflammatory actions and to protect animals and cells from oxidative(More)
BACKGROUND Macrophage inhibitory cytokine-1(MIC-1) is a potential modulator of systemic inflammation and nutritional depletion, both of which are adverse prognostic factors in oesophago-gastric cancer (OGC). METHODS Plasma MIC-1, systemic inflammation (defined as plasma C-reactive protein (CRP) of > or =10 mg l(-1) or modified Glasgow prognostic score(More)
Expression of inducible heat shock protein (HSP70) requires activation of heat shock transcription factor-1 (HSF-1). Recent evidence suggests that interleukin-6 (IL-6) can modify the response of HSF-1 to heat. We hypothesized that IL-6 would prime the HSP response by causing de-repression of HSF-1 resulting in augmented HSP expression in stressed cells. In(More)
PURPOSE A tumor-derived proteolysis-inducing factor (PIF) is suggested to be a potent catabolic factor in skeletal muscle of mice and humans. We aimed to establish the clinical significance of PIF in cancer patients and to elucidate its structural features. EXPERIMENTAL DESIGN PIF was detected in human urine using a monoclonal antibody (mAb) and related(More)
