question:
Hepatocyte nuclear factor 4 (HNF4) is a liver enriched transcription factor and is indispensable for liver development. However, the role of HNF4 in hepatocellular carcinoma (HCC) progression remains to be elucidated. We report that reduced HNF4 expression correlated well with the aggressive clinicopathological characteristics of HCC and predicted poor prognosis of patients. HNF4 levels were even lower in metastatic HCCs, and ectopic HNF4 expression suppressed the metastasis of hepatoma cells both in vitro and in vivo. Forced HNF4 expression attenuated the expression and nuclear translocation of RelA (p65) and impaired NF-B activation through an IKK-independent mechanism. Blockage of RelA robustly attenuated the suppressive effect of HNF4 on hepatoma cell metastasis. MicroRNA (miR)-7 and miR-124 were transcriptionally up-regulated by HNF4, which repressed RelA expression by way of interaction with RelA-3' untranslated region (UTR). In addition, nuclear factor kappa B (NF-B) up-regulated the expression of miR-21 in hepatoma cells, resulting in decreased HNF4 levels through down-regulating HNF4-3'UTR activity.
answer:
Does hepatocyte nuclear factor 4-nuclear factor-B feedback circuit modulate liver cancer progression?

question:
Granulocyte-colony stimulating factor (G-CSF) is used for the mobilization of bone marrow and endothelial progenitor cells, though G-CSF-induced inflammation may cause endothelial dysfunction. We examined the effects of G-CSF on endothelium, C-reactive protein (CRP), tumour necrosis factor-alpha (TNF-alpha) and anti-inflammatory cytokines namely interleukin 10 (IL-10).', 'We studied 60 women with breast cancer, who were randomized to either subcutaneous G-CSF (5 microg/kg), o.d. for 5 days after adjuvant chemotherapy (n = 40) or placebo (n = 20).', 'We measured flow-mediated dilatation (FMD%) of the brachial artery by ultrasonography, CRP, TNF-alpha, IL-10 and the ratio TNF-alpha/ IL-10 blood levels before, 2-h and 5-days after the G-CSF or placebo treatment.', 'There was a greater increase of FMD, IL-10 and reduction of TNF-alpha/ IL-10, 2 h and 5 days after the G-CSF treatment compared to placebo. Although, CRP and TNF-alpha were higher, TNF-alpha/IL-10 was lower at the end of G-CSF treatment compared to placebo. Improvement of FMD was related to changes of IL-10 and TNF-alpha/IL-10.
answer:
Is treatment with granulocyte colony stimulating factor associated with improvement in endothelial function?

question:
Sepsis is an emergency condition with high mortality and morbidity rate. There are limited data on the association of cancer as a risk factor for mortality in sepsis patients in the emergency department (ED).', 'This retrospective study was conducted at the ED, Faculty of Medicine, Ramathibodi Hospital, Bangkok, Thailand. The study period was between January 1st and December 31st, 2014. The inclusion criteria were as follows: adult patients over 15 years of age who presented at the ED with suspicion of sepsis, received treatment at the ED, and whose blood culture was found to be positive. Clinical data were recorded from medical records including the Mortality in Emergency Department Sepsis score (MEDS score). The primary outcome of this study was mortality at one month. Multivariate logistic regression analysis was used to identify independent factors associated with death.', 'During the study period, there were 775 eligible patients. The two most common pathogens identified from blood cultures were Staphylococcus aureus (193 patients; 24.9%) and Escherichia coli (158 patients; 20.4%). At one month after presenting at the ED, 110 patients (14.2%) had died. There were four significant factors for death, having cancer, being on an endotracheal tube, initial diagnosis of bacteremia, and high MED scores. Having cancer had an adjusted OR of 2.12 (95% CI of 1.29, 3.47).
