Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Context: Expression of CINCs was regulated differentially in lipopolysaccharide-stimulated rat macrophages. We examined whether the expression of CINCs in lipopolysaccharide-stimulated rat macrophages is similarly inhibited by anti-inflammatory drugs.', 'Rat peritoneal macrophages were stimulated by lipopolysaccharide in the presence of anti-inflammatory steroids (dexamethasone, prednisolone and hydrocortisone) or non-steroidal anti-inflammatory drugs (indomethacin and piroxicam). The production and mRNA expression of three types of CINCs were measured using enzyme-linked immunosorbent assay and northern hybridization.', 'Anti-inflammatory steroids; dexamethasone, prednisolone and hydrocortisone, dose-dependently inhibited the production of CINC-1, -2 and -3, whose inhibitory patterns were similar to each other. Furthermore mRNA expression of each CINC was inhibited by dexamethasone in a dose-dependent manner. In contrast, non-steroidal anti-inflammatory drugs, indomethacin and piroxicam were without effect. Expression of each CINC was regulated differently; the production of CINC-1 reached a maximum at 12 h and then slightly decreased after lipopolysaccharide stimulation, whereas that of CINC-2 and CINC-3 increased up to 24 h. Dexamethasone inhibited the CINCs production and mRNA expression at 9 h after lipopolysaccharide stimulation.
Answer: These results indicate no difference among CINC-1, -2 and -3 in the inhibition of production and mRNA expression of CINCs by anti-inflammatory steroids, although lipopolysaccharide differentially induces expression of each CINC expression in culture of rat macrophages.

Ex Output:
Is the expression of three types of CINCs by lipopolysaccharide-stimulated rat macrophages inhibited similarly by anti-inflammatory steroids?

Context: Chronic inflammation is hypothesized to influence prostate cancer development, although a definitive link has not been established.', 'Prostate cancer cases (N = 191) detected on a for-cause (clinically indicated) or end-of-study (protocol directed) biopsy, and frequency-matched controls (N = 209), defined as negative for cancer on an end-of-study biopsy, were sampled from the placebo arm of the Prostate Cancer Prevention Trial. Inflammation prevalence and extent in benign areas of biopsy cores were visually assessed using digital images of hematoxylin and eosin-stained sections. Logistic regression was used to estimate associations.', 'Of note, 86.2% of cases and 78.2% of controls had at least one biopsy core (of three assessed) with inflammation in benign areas, most of which was chronic. Men who had at least one biopsy core with inflammation had 1.78 [95% confidence interval (CI), 1.04-3.06] times the odds of prostate cancer compared with men who had zero cores with inflammation. The association was stronger for high-grade disease (Gleason sum 7-10, N = 94; OR, 2.24; 95% CI, 1.06-4.71). These patterns were present when restricting to cases and controls in whom intraprostatic inflammation was the least likely to have influenced biopsy recommendation because their prostate-specific antigen (PSA) was low (<2 ng/mL at biopsy).
Answer: Inflammation, most of which was chronic, was common in benign prostate tissue, and was positively associated with prostate cancer, especially high grade. The association did not seem to be due to detection bias.

Ex Output:
Is chronic inflammation in benign prostate tissue associated with high-grade prostate cancer in the placebo arm of the prostate cancer prevention trial?

Context: Esophageal carcinoma is one of the most aggressive human cancers, and novel treatment modality is required. Although expressing adequate levels of functional tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) receptors DR4/DR5, significant proportion of esophageal cancer cells exhibit resistance to the cytotoxic effect of this ligand. Licochalcone-A (LA), a flavonoid present in a variety of edible plants, exhibits a wide spectrum of pharmacologic properties such as anticancer, antioxidant, and anti-inflammatory activities.', 'Eca109 and TE1 cells were cultured and transfected, then their viability was detected using MTT assay. Immunoprecipitation and immunoblotting analysis and RT-PCR analysis were also performed.', 'In this study, we found that LA synergistically caused the TRAIL-induced apoptosis in Eca109 and TE1 cells. Such potentiation was achieved through inhibiting Akt activation and promoting proteasomal degradation of X-linked Inhibitor of Apoptosis Protein (XIAP) which mediated the survival signals and allow the cells to escape from apoptosis in various human cancers.
Answer: The combination of TRAIL and LA might be a novel therapeutic strategy for esophageal carcinoma patients who fail to respond to standard chemotherapy.

Ex Output:

Does licochalcone-A sensitize human esophageal carcinoma cells to TRAIL-mediated apoptosis by proteasomal degradation of XIAP?
