Q: Activation of the transcription factor NF-B 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 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-B 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-, 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 IKK, 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-, NO, and LDH production in rat pancreatic acinar cells. Cerulein triggered the phosphorylation and nuclear translocation of NF-B p65 subunit, indicating the NF-B 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.

Q: High urine volume enhances urinary free cortisol (UFF) and cortisone (UFE) excretion rates in normal-weight adults and children. Renal excretion rates of glucocorticoids (GC) and their metabolites are frequently altered in obesity. The aim of the present study was to investigate whether UFF and UFE excretion is also affected by urine volume in severely obese subjects.', 'In 24-h urine samples of 59 extremely obese subjects (mean BMI 45.3+/-8.9 kg/m(2)) and 20 healthy lean subjects (BMI 22.1+/-1.8 kg/m(2)), UFF and UFE, tetrahydrocortisol (THF), 5alpha-tetrahydrocortisol (5alpha-THF), and tetrahydrocortisone (THE) were quantified by RIA. The sum of THF, 5alpha-THF, and THE (GC3), the three major GC metabolites, reflects daily cortisol secretion. 11beta-Hydroxysteroid dehydrogenase type 2 (11beta-HSD2) activity was assessed by the ratio UFE/UFF. Daily GC excretion rates were corrected for urine creatinine and adjusted for gender and body weight.', 'In extremely obese subjects, urine volume was significantly associated with creatinine-corrected UFE and 11beta-HSD2 activity after adjustment for gender and BMI (r=0.47, p=0.0002 and r=0.31, p=0.02, respectively). However, urine volume was not associated with creatinine-corrected UFF and GC3 (p=0.4 and p=0.6, respectively). In lean controls, urine volume was significantly associated with creatinine-corrected UFE and UFF (r=0.58, p=0.01 and r=0.55, p=0.02, respectively), whereas urine volume was not associated with 11beta-HSD2 activity after appropriate adjustment (p=0.3).

Q: IQ-domain GTPase-activating protein 1 (IQGAP1) binds to Dishevelled (Dvl) and functions as a modulator of Dvl nuclear localization in Xenopus embryos. However, the relationship between IQGAP1 and Dvl in tumor tissues is unclear.', 'We used immunohistochemistry to assess the expressions of IQGAP1 and Dvl in a cohort of 111 non-small cell lung cancer (NSCLC) patients. Association of their localization expressions with clinicopathological factors was also analyzed.', 'The positive rate of IQGAP1 in primary tumors was 48.6% (54/111) for its cytoplamic expression, 9.0% (10/111) for nuclear expression and 31.5% (35/111) for membranous expression; the positive rate of Dvl was 65.8% (73/111) for cytoplamic expression, 9.9% (11/111) for nuclear expression and 10.8% (12/111) for membranous expression. Coexpression rate of IQGAP1 and Dvl was 77.8% (42/54) in the cytoplasm, 80.0% (8/10) in the nucleus and 8.6% (3/35) in the membrane. Coexpression of IQGAP1 and Dvl in the cytoplasm and nucleus were significantly correlated (P<0.05), but not in the membrane (P>0.05). The positive expression rates of cyclin D1 and c-myc were significantly higher in the group of IQGAP1 and Dvl coexpression in the nucleus than that in the cytoplasm. Coexpression rate of IQGAP1 and Dvl in the cytoplasm and nucleus was significantly higher in lymph nodal metastases (63.3%, 19/30) than in primary growths (38.3%, 31/81), correlating with poor prognosis. Five-year survival time after resection in the group with their coexpression in the cytoplasm and nucleus was significantly lower than that with no coexpression (44.7053.355 vs 58.4032.543 months, p<0.05).

A:
Is coexpression of IQ-domain GTPase-activating protein 1 ( IQGAP1 ) and Dishevelled ( Dvl ) correlated with poor prognosis in non-small cell lung cancer?
