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: Mycophenolate mofetil (MMF) is an effective immunosuppressant developed for use in organ transplantation. It specifically targets lymphocyte purine biosynthesis. However, side effects do occur. Understanding how the active metabolite of MMF, mycophenolic acid (MPA) affects the normally integrated interaction between intracellular purine and pyrimidine pathways might aid the development of improved therapeutic regimes.', 'We used a primary human T-lymphocyte model to study how preincubation with MPA (0.1-50 microM) affected normal ribonucleotide pool responses to phytohemagglutinin using radiolabeled precursors.', 'MPA not only restricted the mitogen-induced expansion of GTP pools, but actually induced a severe drop in both GTP (10% of unstimulated cells) and GDP-sugar pools, with a concomitant fall in ATP (up to 50%). These effects were concentration dependent. By contrast, uridine pools expanded whereas CTP pools remained at resting levels. These changes were confirmed by the altered incorporation of [14C]-bicarbonate and [14C]-glycine into nucleotides. Restriction of [14C]-hypoxanthine incorporation and reduction of [14C]-uridine uptake comparable to that of unstimulated cells indicated that MPA also inhibited both salvage routes of nucleotide synthesis.

Output: Does mycophenolic acid-induced GTP depletion also affect ATP and pyrimidine synthesis in mitogen-stimulated primary human T-lymphocytes?


Input: Consider Input: Evodiamine is one of active alkaloids isolated from the traditional Chinese medicine Evodia rutaecarpa Bentham and has various pharmacological properties. In this study, we investigated its effects on the migration, invasion, and associated mechanism in human nasopharyngeal carcinoma (NPC) cells.', 'Cell viability was determined by MTT assay after evodiamine treatment. Wound-healing assay and Boyden transwell system were used to evaluate the inhibitory effects of evodiamine on cell migration and invasion. MMP-2/9 activity was determined using commercial detection kits. The levels of associated proteins involved in the regulation of cell migration and invasion were analyzed by Western blotting.', 'Evodiamine effectively inhibited the migration and invasion of HONE1 and CNE1 cells, and hardly affected cell proliferation, but significantly suppressed cell adhesion activity in vitro. Additionally, evodiamine treatment significantly decreased mRNA and protein levels of MMP-2 and its activity in the NPC cells, but had little effects on MMP-9 mRNA and protein levels and its activity. Further investigation revealed that evodiamine inhibited the translocation of NF-κB p65, which involves the regulation of MMP-2 expression in cancer invasion. Additionally, evodiamine treatment did not significantly affect the protein levels of JNK, p38, Akt, and their phosphorylated forms and ERK1/2, but strongly attenuated ERK1/2 phosphorylation level, which at least partly accounts for the signal pathway of evodiamine-inhibited migration and invasion of NPC cells.

Output: Does evodiamine inhibit the migration and invasion of nasopharyngeal carcinoma cells in vitro via repressing MMP-2 expression?


Input: Consider Input: Comparative gene identification-58 (CGI-58), an adipose triglyceride lipase (ATGL) coactivator, strongly promotes ATGL-mediated triglyceride (TG) catabolism. Beyond its function in promoting lipolysis, other features of CGI-58 have been proposed. Here, we investigated the role of CGI-58 in the regulation of inflammatory responsiveness in macrophages.', 'Macrophage-specific GCI-58 transgenic mice (TG) and wild type mice (WT) were fed a high fat diet (HFD), and RAW264.7 cells were treated with lipopolysaccharide (LPS). The peroxisome proliferator-activated receptor (PPAR) signaling was detected. The inflammatory responsiveness and mitochondrial function were examined.', 'TG mice showed lower serum levels of proinflammatory cytokines and better mitochondrial function in macrophages compared with WT control. Knockdown of CGI-58 in RAW264.7 cells aggravated LPS-induced inflammation and mitochondrial dysfunction. CGI-58 overexpression and silencing in macrophages induced and inhibited PPARγ expression and activity, respectively. Most importantly, the PPARγ-specific agonist rosiglitazone significantly suppressed inflammation and mitochondrial dysfunction induced by CGI-58 deficiency. Furthermore, knockdown of PPARγ in macrophages significantly dampened the role of CGI-58 in suppression of inflammation and mitochondrial dysfunction. Interestingly, CGI-58 inhibited histone deacetylation and the recruitment of histone deacetylase (HDAC) to the PPARγ promoter. Finally, ATGL deficiency did not affect inflammatory responsiveness and PPARγ signaling in macrophages.


Output: Does macrophage CGI-58 attenuate Inflammatory Responsiveness via Promotion of PPARγ Signaling?
