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.

Question: Context: The aim of this study was to evaluate the effects of maternal obesity on pancreas structure and carbohydrate metabolism in early adult life, focusing on the F1 and F2 generations after F0 maternal pregestational, gestation, and lactation high-fat diet (HF).', 'C57 BL/6 female mice (F0) were fed standard chow (SC) or an HF diet for 8 wk before mating and during the gestation and lactation periods to provide the F1 generation (F1-SC and F1-HF). At 3 mo old, F1 females were mated to produce the F2 generation (F2-SC and F2-HF). The male offspring from all groups were evaluated at 3 mo old.', 'F0-HF and F1-HF dams were overweight before gestation and had a higher body mass gain and energy intake during gestation, although only F0-HF dams presented pregestational hyperglycemia. The F1-HF offspring had higher body mass, energy intake, fasting glucose levels, and were glucose intolerant compared with F1-SC offspring. These parameters were not significantly altered in F2-HF offspring. Both F1-HF and F2-HF offspring showed hyperinsulinemia, hyperleptinemia, decreased adiponectin levels, increased pancreatic mass, and islet volume density with elevated α- and β-cell mass, hypertrophied islet characterized by an altered distribution of α- and β-cells and weak pancreatic-duodenal homeobox (Pdx)1 immunoreactivity.\Question: Does pregestational maternal obesity impair endocrine pancreas in male F1 and F2 progeny?

Answer: Maternal HF diet consumed during the preconception period and throughout the gestation and lactation periods in mice promotes metabolism and pancreatic programming in F1 and F2 male offspring, implying intergenerational effects.


Question: Context: Intermittent hypoxia (IH)-induced activation of pro-inflammatory pathways is a major contributing factor to the cardiovascular pathophysiology associated with obstructive sleep apnea (OSA). Obesity is commonly associated with OSA although it remains unknown whether adipose tissue is a major source of inflammatory mediators in response to IH. The aim of this study was to test the hypothesis that IH leads to augmented inflammatory responses in human adipocytes when compared to cells of non-adipocyte lineages.', 'Human primary subcutaneous and visceral adipocytes, human primary microvascular pulmonary endothelial cells (HUMEC-L) and human primary small airway epithelial cells (SAEC) were exposed to 0, 6 or 12 cycles of IH or stimulated with tumor necrosis factor (TNF)-α. IH led to a robust increase in NF-κB DNA-binding activity in adipocytes compared with normoxic controls regardless of whether the source of adipocytes was visceral or subcutaneous. Notably, the NF-κB response of adipocytes to both IH and TNF-α was significantly greater than that in HUMEC-L and SAEC. Western blotting confirmed enhanced nuclear translocation of p65 in adipocytes in response to IH, accompanied by phosphorylation of I-κB. Parallel to p65 activation, we observed a significant increase in secretion of the adipokines interleukin (IL)-8, IL-6 and TNF-α with IH in adipocytes accompanied by significant upregulation of mRNA expression. PCR-array suggested profound influence of IH on pro-inflammatory gene expression in adipocytes.\Question: Are human adipocytes highly sensitive to intermittent hypoxia induced NF-kappaB activity and subsequent inflammatory gene expression?

Answer: Human adipocytes demonstrate strong sensitivity to inflammatory gene expression in response to acute IH and hence, adipose tissue may be a key source of inflammatory mediators in OSA.


Question: Context: Esophageal eosinophilia can be proton pump inhibitor (PPI) resistant or responsive, representing 2 entities known as eosinophilic esophagitis (EoE) and PPI-responsive esophageal eosinophilia (PPI-REE), respectively. Although they present with similar clinical features, EoE is accepted to be an antigen-driven, TH2-associated allergic disorder, whereas the cause of PPI-REE remains a mystery.', 'In this study, our aim was to investigate the pathogenesis of PPI-REE by using a recently described EoE diagnostic panel (EDP) composed of a set of 94 esophageal transcripts and to determine whether PPI therapy reverses any esophageal transcriptional abnormalities.', 'We evaluated the EDP signature in biopsy samples obtained from adult and pediatric patients with PPI-REE from 4 institutions and compared the pre- and post-PPI therapy expression profiles of these subjects with those of patients with active EoE.', 'The EDP differentiated patients with EoE from control subjects with 100% accuracy among the 4 clinical sites. Bioinformatics analysis revealed largely overlapping transcriptomes between patients with PPI-REE and those with EoE, including the genes for eosinophil chemotaxis (eotaxin 3, CCL26), barrier molecules (desmoglein 1, DSG1), tissue remodeling (periostin, POSTN), and mast cells (carboxypeptidase A, CPA3). PPI monotherapy alone almost completely reversed the allergic inflammatory transcriptome of patients with PPI-REE. Furthermore, we identified a set of candidate genes to differentiate patients with EoE from those with PPI-REE before treatment.\Question: Does transcriptome analysis of proton pump inhibitor-responsive esophageal eosinophilia reveal proton pump inhibitor-reversible allergic inflammation?

Answer:
These findings provide definitive evidence that PPI-REE is a disease entity with significant molecular overlap with EoE, suggesting that many patients with PPI-REE represent a continuum of the same pathogenic allergic mechanisms that underlie EoE and thus might constitute a subphenotype of patients with EoE. The ability of PPI therapy to nearly entirely reverse gene expression associated with PPI-REE, particularly that associated with classic features of allergic inflammation, provides new insight into potential disease etiology and management strategies for patients with significant esophageal eosinophilia.
