question:
Activation of the transcription factor NF-κB and expression of pro-inflammatory mediators have been considered as major events of acute pancreatitis (AP). Karyopherin alpha 2 (KPNA2), a member of the importin α family, reportedly modulates p65 subcellular localization.', 'This study aimed to investigate the expression and possible functions of KPNA2 in the AP cell and animal model, focusing on its association with NF-κB activation.', 'An AP cell model was established with the cerulein-stimulated AR42J and isolated rat pancreatic acinar cells. The AP rat model was induced by the intraperitoneal injection of cerulein. The secretion of TNF-α, IL-6, and LDH was detected by ELISA kits and the production of NO using nitric oxide kit. Expression of KPNA2 was measured by RT-PCR and Western blot. Expression levels of IKKα, phosphorylation of p65, and total p65 were detected by Western blot. Co-localization of KPNA2 with p65 was observed by immunofluorescence assay. To determine the biological functions of KPNA2 in cerulein-induced inflammatory response, RNA interference was employed to knockdown KPNA2 expression in AR42J and isolated pancreatic acini cells.', 'Cerulein stimulated KPNA2 expression and IL-6, TNF-α, NO, and LDH production in rat pancreatic acinar cells. Cerulein triggered the phosphorylation and nuclear translocation of NF-κB p65 subunit, indicating the NF-κB activation. The co-localization and nuclear accumulation of KPNA2 and p65 were detected in cerulein-treated cells. Knocking down KPNA2 hindered cerulein-induced nuclear transportation of p65 and alleviated the subsequent inflammatory response in rat pancreatic acinar cells. Additionally, KPNA2 expression was significantly up-regulated in cerulein-induced AP rat model.
answer:
Does karyopherin Alpha 2 promote the Inflammatory Response in Rat Pancreatic Acinar Cells Via Facilitating NF-κB Activation?


question:
To evaluate whether the relationship between dietary composition and plasma lipid levels is genetically determined.', 'We have evaluated the influence of common apolipoprotein A5 (APOA5) variants (T-1131 > C, Ser19 > Trp and Val153 > Met) on plasma lipid concentrations in 117 males for whom dietary composition markedly changed and total cholesterol decreased (from 6.21 +/- 1.31 mmol/L in 1988 to 5.43 +/- 1.06 mmol/L in 1996) over an 8 year follow-up study.', 'APOA5 T-1131 > C and Val153 > Met variants did not influence the change in lipid measures over time. In Ser/Ser19 homozygotes, the plasma cholesterol was relatively stable over the years (6.1 +/- 1.2 mmol/L in 1988 and 5.6 +/- 1.0 mmol/L in 1996, -8%, P < 0.01). In contrast, in the Trp19 carriers, the decrease of the plasma cholesterol was more than 20% (6.5 +/- 1.6 mmol/L in 1988 and 5.1 +/- 1.0 mmol/L in 1996) (P < 0.001). The difference of the changes is significant (8% vs. 20%, P < 0.005). Changes in other analyzed lipid parameters have not been significantly associated with APOA5 variants.
answer:
Does aPOA5 variant Ser19Trp influence a decrease of the total cholesterol in a male 8 year cohort?


question:
Olfaction is a fundamental sense through which most animals perceive the external world. The olfactory system detects odors via specialized sensory organs such as the main olfactory epithelium and the vomeronasal organ. Sensory neurons in these organs use G-protein coupled receptors to detect chemosensory stimuli. The odorant receptor (OR) family is expressed in sensory neurons of the main olfactory epithelium, while the adult vomeronasal organ is thought to express other types of receptors.', 'Here, we describe Olfr692, a member of the OR gene family identified by next-generation RNA sequencing, which is highly upregulated and non-canonically expressed in the vomeronasal organ. We show that neurons expressing this gene are activated by odors emanating from pups. Surprisingly, activity in Olfr692-positive cells is sexually dimorphic, being very low in females. Our results also show that juvenile odors activate a large number of Olfr692 vomeronasal neurons in virgin males, which is correlated with the display of infanticide behavior. . In contrast, activity substantially decreases in parenting males (fathers), where infanticidal aggressive behavior is not frequently observed.
answer:

Is detection of pup odors by non-canonical adult vomeronasal neurons expressing an odorant receptor gene influenced by sex and parenting status?
