Label-Free Quantitative Proteomics Unravels Carboxypeptidases as the Novel Biomarker in Pancreatic Ductal Adenocarcinoma. Transl Oncol 2018; 11:691-699.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers, with a high mortality rate and poor prognosis. However, little is known concerning the molecular mechanism of PDAC at the proteomics level. Here we report a proteomics analysis of PDAC tumor and adjacent tissues by shotgun proteomics followed by label-free quantification, and in total, 3031 and 3306 proteins were identified in three pairs of PDAC tumor and adjacent tissues, respectively; 40 of them were differentially expressed for at least three-fold in PDAC tumor tissues. Ontological and interaction network analysis highlighted the dysregulation of a set of four proteins in the carboxypeptidase family: carboxypeptidase A1 (CPA1), A2 (CPA2), B1 (CPB1), and chymotrypsin C (CTRC). Western blotting confirmed the downregulation of the carboxypeptidase network in PDAC. Immunohistochemistry of tissue microarray from 90 PDAC patients demonstrated that CPB1 was downregulated 7.07-fold (P < .0001, n = 81) in tumor comparing with the peritumor tissue. Further 208 pancreatic tissues from PDAC tumor, peritumor, and pancreatis confirmed the downregulation of CPB1 in the PDAC patients. In summary, our results displayed that the expression of carboxypeptidase is significantly downregulated in PDAC tumor tissues and may be novel biomarker in the patient with PDAC.

Int Arch Otorhinolaryngol 2017; 21:122-125.

Abstract
Introduction Nasal polyposis (NP) is a chronic inflammatory condition of the upper airway characterized by overgrowth of nasal mucosa. Recent studies have shown a mechanical dysfunction in the nasal polyp tissue. Objective This study aims to evaluate the mechanical properties of nasal fibrotic tissue. Method This study was an institutional review board approved translational study in 20 participants (8 patients with NP, 7 patients with nasal synechiae, and 5 subjects without sinus disease (control group). We used Controlled Disc Stimulation equipment to compare the curve Pressure/Volume created during the saline solution infusion. Results The increase of pressure in response to solution injection was lower in the nasal polyp group when compared with control middle turbinate group and fibrotic group. No significant difference was found in the pressure response during solution injection between fibrotic group and control middle turbinate group. Inferior turbinate group showed significant difference when compared with control middle turbinate group. Conclusion The mechanical dysfunction found in the nasal mucosa of patients with NP provides new insight into this condition. These data allow the belief that the fibrosis has a potential role in increasing interstitial hydrostatic pressure and, consequently, mitigating edema formation in NP.

Abstract
BACKGROUND Heparanase (HPA) is known to be involved in tissue remodeling of various organs with inflammatory diseases. The aim of this study was to investigate the level of expression and the pattern of distribution of HPA in normal human sinus mucosa, inflammatory sinus mucosa, and nasal polyps to evaluate the possible effect of HPA on the tissue remodeling of chronic inflammatory sinus mucosa and nasal polyps. METHODS Normal sinus mucosa was obtained from the ethmoid sinus during endoscopic reduction in 25 patients with blowout fractures. Inflammatory sinus mucosa and nasal polyps were obtained from 25 patients undergoing endoscopic sinus surgery for chronic sinusitis with nasal polyps. The levels of expression and the pattern of distribution of HPA were evaluated in normal human sinus mucosa, inflammatory sinus mucosa, and nasal polyps, using reverse transcriptase-polymerase chain reaction, immunohistochemical analysis, and Western blot analysis. RESULTS HPA mRNA and protein were detected in inflammatory sinus mucosa and nasal polyps but not in normal sinus mucosa. HPA was mainly localized in the vascular endothelium, epithelium, submucosal glands, and inflammatory cells of inflammatory sinus mucosa. In nasal polyps, inflammatory cells and vascular endothelium showed immunopositivity in the entire portion, whereas glands and epithelial cells did not show positivity. CONCLUSION Our results indicate that HPA is not constitutively expressed in normal sinus mucosa and is upregulated in chronic inflammatory sinus mucosa and nasal polyps, suggesting that HPA may play an important role in the tissue remodeling in chronic sinusitis.

Significance of susceptible gene expression profiles in nasal polyposis. Clin Exp Otorhinolaryngol 2008; 1:177-83.

Abstract
Nasal polyposis (NP) is a common chronic inflammatory disease of the rhinosinus mucosa and a complex disease with strong genetic and environmental components. During the past 10 to 20 yr, many studies have been performed to determine differential gene expression profiles between NP and normal nasal tissues, in order to identify susceptible genes that are associated with NP-related traits. Despite achievement in the identification of candidate genes and their associated pathogenic pathways, the large challenges remain as the genetic and molecular alterations required for its development and progression are still unclear. Therefore, the development of novel, powerful tools for gene discovery, and a closer integration of genetics and medical biology would provide valuable insight into the pathogenesis of NP.

Abstract
CONCLUSION The qualitative and quantitative compositions of GAGs were comparable in all the polyps examined. OBJECTIVE Glycosoaminoglycans (GAGs) are an integral component of proteoglycans, which are constituents of connective tissue. The qualitative and quantitative compositions of GAGs occurring in proteoglycans determine their biological role. In this work, individual fractions of GAGs occurring in nasal polyps were isolated and estimated. MATERIAL AND METHODS Polyps were obtained over a 2-year period from 31 patients (18 males, 13 females; age range 28-70 years) who underwent polypectomy and evaluated using routine histopathology. RESULTS The amount of hyaluronic acid in nasal polyps was high, the amounts of dermatane sulphate and chondroitine-6-sulphate were slightly lower and the amounts of chondroitine-4-sulphate, heparin, heparan sulphate and keratan sulphate were the lowest.

Abstract
To explore the role of tenascin (TN) and fibronectin (FN) in the pathophysiology of nasal polyps (NP), the expression of TN and FN in NP from 34 patients and inferior turbinates from 20 patients with deviation of nasal septum was immunohistochemically studied. In patients with NP, the relations between expression and histopathological features, eosinophils (EOS) infiltration, clinical staging and the size of NP were analyzed. Our study showed that the gray score of TN and FN expression was 163.10 +/- 10.54 and 163.24 +/- 11.52 in NP respectively, whereas it was 175.49 +/- 9.29 and 173.93 +/- 7.92 in inferior turbinates respectively. The difference between two groups was significant (P < 0.01). The expression of TN and FN in endematous type was significantly stronger than that in cystic and glandular type and fibrous type (P < 0.05). The association between FN expression and EOS infiltration was significant (r = -0.60, P < 0.01). The expression of TN and FN did not correlate with clinical staging and size (P > 0.05). It was suggested that abnormal ECM might contribute to proliferation of epithelia, accumulation of EOS and edema formation, thereby causing development of NP.
