Given a passage, 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.

Input: Consider Input: Immunologic abnormalities have been found in bipolar disorder but pentraxin 3, a marker of innate immunity, has not been studied in this population.', 'Levels of pentraxin 3 were measured in individuals with bipolar disorder, schizophrenia, and non-psychiatric controls. Linear regression models were used to compare the pentraxin 3 levels in each of the psychiatric groups to that in the control group, adjusting for demographic and clinical variables. Logistic regression models were used to calculate the odds ratios associated with levels of pentraxin 3 which differed from specified levels of the control group.', 'The sample consisted of 831 individuals: 256 with bipolar disorder, 309 with schizophrenia, and 266 without a psychiatric disorder. The levels of pentraxin 3 in the bipolar disorder, but not in the schizophrenia, group were significantly lower than those of controls, adjusting for age, gender, race, maternal education, smoking status, and body mass index (t = -3.78, p < 0.001). The individuals with bipolar disorder also had significantly increased odds of having low levels of pentraxin 3 relative to both the 10th and 25th percentile level of the controls and significantly decreased odds of having a level greater than the 75th and the 90th percentile level of the controls, adjusting for the same covariates.

Output: Is pentraxin 3 reduced in bipolar disorder?


Input: Consider Input: SPARC (secreted protein acidic, rich in cysteine) is a matricellular protein that has been found to be activated in a number of human cancers. More recently, it has been shown to be upregulated in human gastric and colorectal cancer. We therefore wished to address the functional importance of SPARC upregulation to intestinal tumorigenesis in vivo.', 'SPARC upregulation was determined in intestinal adenomas of tumour-prone Apc(Min/+) mice at both the RNA and the protein level. To determine the functional importance of SPARC for intestinal tumorigenesis we then intercrossed Sparc knockout mice with Apc(Min/+) mice (n = 20). Intestinal enterocyte migration was examined using bromodeoxyuridine labelling studies.', 'Levels of murine Sparc and several related proteins were upregulated in adenomas arising in Apc(Min/+) mice. A deficiency of Sparc strongly suppressed adenoma formation in Apc(Min/+) mice (p>or=0.0001). Importantly, a deficiency of Sparc also accelerated enterocyte migration (p = 0.01), as perturbed slow epithelial migration may underpin adenoma formation in the intestine.

Output: Does deficiency of SPARC suppress intestinal tumorigenesis in APCMin/+ mice?


Input: Consider Input: To examine the in vitro effects of LL37 on the expression of vascular endothelial growth factor (VEGF) in human pulp cells and to identify the intracellular signalling pathway involved.', 'Pulp cells at passage 6 were treated with 10 μg mL(-1) synthesized LL37, and an inhibition assay was performed with MAPK or NF-κB inhibitors to determine the possible signalling pathway. VEGF mRNA, VEGF protein and phosphorylated ERK1/2 levels were determined by real-time PCR, ELISA and Western blot, respectively. Data were analysed using t-tests.', 'LL37 significantly increased both the mRNA and protein levels of VEGF in pulp cells (P < 0.01). However, pre-treatment with an ERK kinase inhibitor suppressed these increases. Furthermore, the inhibitor blocked LL37-induced ERK1/2 phosphorylation.


Output: Does lL37 induce VEGF expression in dental pulp cells through ERK signalling?
