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.

Input: Consider Input: Context: To test whether oral L-81 treatment could improve the condition of mice with diabetes and to investigate how L-81 regulates microsomal triglyceride transfer protein (MTP) activity in the liver.', 'Genetically diabetic (db/db) mice were fed on chow supplemented with or without L-81 for 4 wk. The body weight, plasma glucose level, plasma lipid profile, and adipocyte volume of the db/db mice were assessed after treatment. Toxicity of L-81 was also evaluated. To understand the molecular mechanism, HepG2 cells were treated with L-81 and the effects on apolipoprotein B (apoB) secretion and mRNA level of the MTP gene were assessed.', 'Treatment of db/db mice with L-81 significantly reduced and nearly normalized their body weight, hyperphagia and polydipsia. L-81 also markedly decreased the fasting plasma glucose level, improved glucose tolerance, and attenuated the elevated levels of plasma cholesterol and triglyceride. At the effective dosage, little toxicity was observed. Treatment of HepG2 cells with L-81 not only inhibited apoB secretion, but also significantly decreased the mRNA level of the MTP gene. Similar to the action of insulin, L-81 exerted its effect on the MTP promoter.\Question: Does pluronic L-81 ameliorate diabetic symptoms in db/db mice through transcriptional regulation of microsomal triglyceride transfer protein?

Output: L-81 represents a promising candidate in the development of a selective insulin-mimetic molecule and an anti-diabetic agent.


Input: Consider Input: Context: Secretory phospholipases A2 (sPLA2) initiate the biosynthesis of eicosanoids, are increased in the airways of people with severe asthma, and induce mucin hypersecretion. We used IL-13-transformed, highly enriched goblet cells and differentiated (ciliary cell-enriched) human bronchial epithelial cell culture to evaluate the relative contribution of ciliated and goblet cells to airway sPLA2 generation and response. We wished to determine the primary source(s) of sPLA2 and leukotrienes in human airway epithelial cells.', 'Human bronchial epithelial cells from subjects without lung disease were differentiated to a ciliated-enriched or goblet-enriched cell phenotype. Synthesis of sPLA2, cysteinyl leukotrienes (cysLTs), and airway mucin messenger RNA and protein was measured by real-time-polymerase chain reaction and an enzyme-linked immunosorbent assay, and the localization of mucin and sPLA2 to specific cells types was confirmed by confocal microscopy.', 'sPLA2 group IIa, V, and X messenger RNA expression was increased in ciliated-enriched cells (P < .001) but not in goblet-enriched cells. sPLA2 were secreted from the apical (air) side of ciliated-enriched cells but not goblet-enriched cells (P < .001). Immunostaining of sPLA2 V was strongly positive in ciliated-enriched cells but not in goblet-enriched cells. sPLA2 released cysLTs from goblet-enriched cells but not from ciliated-enriched cells, and this result was greatest with sPLA2 V (P < .05). sPLA2 V increased goblet-enriched cell mucin secretion, which was inhibited by inhibitors of lipoxygenase or cyclooxygenase (P < .02).\Question: Are secretory phospholipases A2 secreted from ciliated cells and increase mucin and eicosanoid secretion from goblet cells?

Output: sPLA2 are secreted from ciliated cells and appear to induce mucin and cysLT secretion from goblet cells, strongly suggesting that airway goblet cells are proinflammatory effector cells.


Input: Consider Input: Context: Stable polyamine homeostasis is important for cell survival and regeneration. Our experimental studies have shown that catabolism of spermidine and spermine to putrescine is associated with the development of pancreatitis. We investigated the pathogenetic role of polyamine catabolism by studying the effect of a methylated polyamine analog on taurodeoxycholate-induced acute experimental pancreatitis.', 'Acute pancreatitis was induced by infusion of sodium taurodeoxycholate (2%) into the pancreatic duct. Bismethylspermine (Me(2)Spm) was administered as a pretreatment before the induction of pancreatitis or as a treatment after the induction of pancreatitis. The sham operation included laparotomy only. Pancreas tissue and blood were sampled at 24 h and 72 h after the infusion of taurodeoxycholate and studied for pancreatitis severity (serum amylase activity, pancreatic water content, and histology) and polyamine catabolism, which includes spermidine/spermine N(1)-acetyltransferase (SSAT) activity as well as spermidine, spermine, and putrescine concentrations in the pancreas.', 'Sodium taurodeoxycholate-induced acute pancreatitis manifests as increases in serum amylase and pancreatic water content, leukocytosis, and acinar cell necrosis in the pancreas. The activity of SSAT increased significantly together with an increase in the ratios of pancreatic putrescine/spermidine and putrescine/spermine at 24 h, which indicates SSAT-induced polyamine catabolism. Pancreatic water content and necrosis were reduced significantly by the treatment with Me(2)Spm at 24 h but not at 72 h when the polyamine homeostasis had recovered, and the pancreatitis had progressed.\Question: Does a polyamine analog bismethylspermine ameliorate severe pancreatitis induced by intraductal infusion of taurodeoxycholate?


Output: Taurodeoxycholate-induced acute pancreatitis was associated with activation of polyamine catabolism in the pancreas. The polyamine analog Me(2)Spm ameliorated the injury in the early stage, but it did not ameliorate the late progression of the pancreatic necrosis at 72 h. Thus, besides proteolytic enzyme activation and the cascades of inflammation, polyamine catabolism may be an important pathogenetic mediator of the early stages of acute pancreatitis.
