In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Example Input: Context: This study was conducted to determine if there was an increase in the urinary excretion of fluoride, after the use of fluoride mouth rinses in children.', 'The sample consisted of 58 children aged 5-8 years, randomly selected, residents in non-fluoridated water areas. Urine samples were collected prior to mouthwash and also 2 hours after use. The control sample, which received no treatment, consisted of 16 children of equivalent age and from the same community. Urinary excretion of fluoride was analysed by determining the pH, creatinine, F- ion and fluoride (mg)/creatinine (g) (F/Cr) ratio in urine. Results In the studied sample, the mean F/Cr ratio before fluoride mouth rinse was 0.26 mg/g and it rose to 1.58 mg/g 2 hours after mouth rinse. This difference of 1.33 mg/g was statistically highly significant (p<.001). In the control group no significant changes occurred. The average 2 hours afterward F/Cr ratios were 0.29 and 0.27 respectively (p=0.426).\Question: Does renal excretion of fluoride after fluoride mouth rinse in children?
Example Output: After the use of a fluoride mouthwash, in children, there is a statistically significant increase of fluoride ion in urine, which can be attributed to the application of this product.

Example Input: Context: Targeting the energy storing white adipose tissue (WAT) by pharmacological and dietary means in order to promote its conversion to energy expending "brite" cell type holds promise as an anti-obesity approach. Present study was designed to investigate/revisit the effect of capsaicin on adipogenic differentiation with special reference to induction of "brite" phenotype during differentiation of 3T3-L1 preadipocytes.', 'Multiple techniques such as Ca2+ influx assay, Oil Red-O staining, nutrigenomic analysis in preadipocytes and matured adipocytes have been employed to understand the effect of capsaicin at different doses. In addition to in-vitro experiments, in-vivo studies were carried out in high-fat diet (HFD) fed rats treated with resiniferatoxin (RTX) (a TRPV1 agonist) and in mice administered capsaicin.', 'TRPV1 channels are expressed in preadipocytes but not in adipocytes. In preadipocytes, both capsaicin and RTX stimulate Ca2+ influx in dose-dependent manner. This stimulation may be prevented by capsazepine, a TRPV1 antagonist. At lower doses, capsaicin inhibits lipid accumulation and stimulates TRPV1 gene expression, while at higher doses it enhances accumulation of lipids and suppresses expression of its receptor. In doses of 0.1-100 µM, capsaicin promotes expression of major pro-adipogenic factor PPARγ and some of its downstream targets. In concentrations of 1 µM, capsaicin up-regulates anti-adipogenic genes. Low-dose capsaicin treatment of 3T3-L1 preadipocytes differentiating into adipocytes results in increased expression of brown fat cell marker genes. In white adipose of mice, capsaicin administration leads to increase in browning-specific genes. Global TRPV1 ablation (i.p. by RTX administration) leads to increase in locomotor activity with no change in body weight.\Question: Does capsaicin induce `` brite '' phenotype in differentiating 3T3-L1 preadipocytes?
Example Output: Our findings suggest the dual modulatory role of capsaicin in adipogenesis. Capsaicin inhibits adipogenesis in 3T3-L1 via TRPV1 activation and induces brown-like phenotype whereas higher doses.

Example Input: Context: Homeobox genes are often deregulated in cancer and can have both oncogenic and tumor-suppressing potential. The Caudal-related homeobox transcription factor 2 (CDX2) is an intestine-specific transcription factor. CDX2 has been implicated in differentiation, proliferation, cell adhesion, and migration. In this study, we investigated CDX2 mRNA and protein expression in relation to the clinicopathological characteristics of colon cancer, including mismatch repair status and recurrence risk.', 'Tumor samples were obtained from colon cancer patients. Biopsies from tumor tissue and normal adjacent tissue were fixed in liquid nitrogen for RNA extraction or in formalin and paraffin embedded (FFPE) for immunohistochemical staining. CDX2 mRNA expression was evaluated by RT-qPCR. FFPE sections were stained for MLH1, MSH2, MSH6, PMS2, and CDX2.', 'A total of 191 patient samples were included in the study and analyzed by immunohistochemistry. Of these samples, 97 were further evaluated by RT-qPCR. There was no significant difference in CDX2 mRNA expression between tumor and normal tissues. CDX2 mRNA expression was significantly lower in right-sided tumors (p<0.05), poorly differentiated tumors (p<0.05), and MMR-deficient tumors (p<0.05). Similarly, CDX2 protein expression was more often low or absent in right-sided tumors (p<0.01), poorly differentiated tumors (p<0.001), and MMR-deficient tumors (p<0.001). Low CDX2 protein or mRNA expression was not associated with recurrence risk.\Question: Is cDX2 downregulation associated with poor differentiation and MMR deficiency in colon cancer?
Example Output:
We found that CDX2 downregulation is associated with MMR deficiency, right-sided tumors, and poor differentiation at both the mRNA and protein level. Whether CDX2 plays an active role in tumor progression in MSI/MMR-deficient tumors remains to be elucidated.
