Abstract
INTRODUCTION Antigen-specific active immunotherapy is an investigational therapeutic approach of potential interest for bladder cancer regardless of disease stage. Clinical development of antigen-specific immunotherapeutics against bladder cancer must be preceded by assessment of the expression of relevant genes in bladder tumors. The objectives of this study (NCT01706185) were to assess the rate of expression of the MAGE-A3 and PRAME genes in bladder tumors and to investigate the feasibility of using formalin-fixed paraffin-embedded (FFPE) tumor tissues for testing. MATERIALS AND METHODS Archived FFPE bladder tumor specimens (any stage) were tested for mRNA expression of MAGE-A3 and PRAME using antigen-specific quantitative reverse transcription polymerase chain reaction assays. Data on patients and tumor characteristics were obtained from hospital records to investigate these characteristics' possible association with the antigen expression. RESULTS Over 92% of the 156 tumors examined gave valid antigen test results. Of the tumors with a valid test, 46.5% were MAGE-A3-positive, 32.2% were PRAME-positive and 59.7% positive for at least one of them. Exploratory analyses of possible associations between antigen expression and patient or tumor characteristics did not identify clear associations between antigen expression and any of the variables investigated. CONCLUSIONS Assessment of tumor antigen mRNA expression by using FFPE bladder tissues was feasible. The rates of MAGE-A3-positive and PRAME-positive tumors indicate that both antigens may be interesting targets for immunotherapeutics against bladder cancer.

Abstract
BACKGROUND Residual neck disease after radiotherapy in advanced oropharyngeal squamous cell carcinoma (OPSCC) is associated with increased mortality, and some patients may benefit from post-radiotherapy neck dissection (PRND). The aim of the present study was to assess the value of magnetic resonance imaging (MRI) and other clinical characteristics in selecting patients for PRND. MATERIALS AND METHODS Retrospective cohort study. Consecutive patients with N+ OPSCC were included. Medical records, pathology reports and imaging reports were reviewed. Pre- and post-therapeutic imaging was re-evaluated. RESULTS A total of 100 consecutive patients from a three-year period were included. Neck response was evaluated with MRI two months after treatment. Sixty patients were suspicious for residual neck disease, and were offered surgery; seven of these patients had histologic evidence of carcinoma. Cumulative neck failure after three years was 14% (8.4-24%), and did not differ significantly among patients with positive compared to negative MRI (radiologist's initial description; p = 0.47, log-rank test). Applying neck failure as gold standard, sensitivity and specificity of MRI was 69% and 41%, respectively; positive and negative predictive value was 15% and 90%. Patients with p16 + disease had significantly larger lymph nodes after treatment, and imaging based on lymph node size resulted in many false positives. Analysis of receiver operating characteristic curves in 191 individual lymph nodes showed that a short axis ≥ 10 mm should be classified as suspicious. Furthermore, T-stage and p16-status were associated with increased risk of neck recurrence. Salvage was successful in four patients with early detected nodal recurrence. CONCLUSION These results suggest that lymph node size, T-stage and p16 status could be used in selecting patients for PRND in OPSCC. Yet, early anatomical imaging may be inappropriate for evaluating neck response in patients with p16 + disease as enlarged lymph nodes often do not indicate residual neck disease.

Abstract
BACKGROUND Kindlins (FERMT) are cytoplasmic proteins required for integrin (ITG) activation, leukocyte transmigration, platelet aggregation and thrombosis. Characterization of kindlins and their association with atherosclerotic plaques in human(s) is lacking. METHODS AND RESULTS Exploratory microarray (MA) was first performed followed by selective quantitative validation of robustly expressed genes with qRT-PCR low-density array (LDA). In LDA, ITGA1 (1.30-fold, p = 0.041) and ITGB3 (1.37-fold, p = 0.036) were upregulated in whole blood samples of patients with coronary artery disease (CAD) compared to healthy controls. In arterial plaques, both robustly expressed transcript variants of FERMT3 (MA: 5.90- and 3.4-fold; LDA: 3.99-fold, p < 0.0001 for all) and ITGB2 (MA: 4.81- and 4.92-fold; LDA: 5.29-fold, p < 0.0001 for all) were upregulated while FERMT2 was downregulated (MA: -1.61-fold; LDA: -2.88-fold, p < 0.0001 for both). The other integrins (ITGA1, ITGAV, ITGB3, ITGB5) were downregulated. All these results were replicated in at least one arterial bed. The latter FERMT3 transcript variant associated with unstable plaques (p = 0.0004). FERMT3 correlated with M2 macrophage markers and in hierarchical cluster analysis clustered with inflammatory and macrophage markers, while FERMT2 correlated with SMC-rich plaque markers and clustered with SMC markers. In confocal immunofluorescence analysis, FERMT3 protein colocalized with abundant CD68-positive cells of monocytic origin in the atherosclerotic plaques, while co-localization of FERMT3 with HHF35 indicative of smooth muscle cells was low. CONCLUSIONS Kindlin-3 (FERMT3) is upregulated in atherosclerotic, especially unstable plaques, mainly in cells of monocytic origin and of M2 type. Simultaneous upregulation of ITGB2 suggests a synergistic effect on leukocyte adherence and transmigration into the vessel wall.

Abstract
Development of novel diagnostic and therapeutic approaches in cancer research requires sensitive and quantitative assays for determination of cancer associated proteins in clinical samples. Novel quantitative targeted proteomic approaches are overviewed in this communication. A major advantage of selected reaction monitoring (SRM) and pseudo- SRM lies in the selective and sensitive quantification of selected proteins in large sample sets. As such, they represent an alternative to immunochemical approaches. On the other hand, the potential of HRM and SWATH lies in recording of digital fingerprints, which enable post acquisition quantitative proteomic data mining on a similar basis to SRM. This article shows applications of targeted proteomics in a number of cancer research studies where they were used for quantification and validation of current or potential protein bio-markers and to study their role in cancer development and progression.

Abstract
Background Squamous cell carcinomas (SCC) account for approximately 30% of non-small cell lung cancer (NSCLC). Current staging methods do not adequately predict outcome for this disease. EMX2 is a homeo-domain containing transcription factor known to regulate a key developmental pathway. This study assessed the significance of EMX2 as a prognostic and predictive marker for resectable lung SCC. Methods Two independent cohorts of patients with lung SCC undergoing surgical resection were studied. EMX2 protein expression was examined by immunohistochemistry, Western blot, or immunofluorescence. EMX2 expression levels in tissue specimens were scored and correlated with patient outcomes. Chemo-sensitivity of lung SCC cell lines stably transfected with EMX2 shRNAs to cisplatin, carboplatin, and docetaxel was examined in vitro. Results EMX2 expression was down-regulated in lung SCC tissue samples compared to their matched adjacent normal tissues. Positive EMX2 expression was significantly associated with improved overall survival in stage I lung SCC patients, and in stage II/IIIA lung SCC patients receiving adjuvant chemotherapy. EMX2 expression was also associated with expression of EMT markers in both lung SCC cell lines and tissue samples. Knock-down of EMX2 expression in lung SCC cells promoted chemo-resistance and cell migration. Conclusions EMX2 expression is down-regulated in lung SCC and its down-regulation is associated with chemo-resistance in lung SCC cells, possibly through regulation of Epithelial-to-Mesenchymal Transition (EMT). EMX2 may serve as a novel prognostic marker for stage I lung SCC patients and a prediction marker for stage II/IIIA lung SCC patients receiving adjuvant chemotherapy.

Abstract
Hypoxic areas are a common feature of rapidly growing malignant tumors and their metastases and are typically spatially heterogeneous. Hypoxia has a strong impact on tumor cell biology and contributes to tumor progression in multiple ways. To date, only a few molecular key players in tumor hypoxia, such as hypoxia-inducible factor-1 (HIF-1), have been discovered. The distribution of biomolecules is frequently heterogeneous in the tumor volume and may be driven by hypoxia and HIF-1α. Understanding the spatially heterogeneous hypoxic response of tumors is critical. Mass spectrometric imaging (MSI) provides a unique way of imaging biomolecular distributions in tissue sections with high spectral and spatial resolution. In this paper, breast tumor xenografts grown from MDA-MB-231-HRE-tdTomato cells, with a red fluorescent tdTomato protein construct under the control of a hypoxia response element (HRE)-containing promoter driven by HIF-1α, were used to detect the spatial distribution of hypoxic regions. We elucidated the 3D spatial relationship between hypoxic regions and the localization of lipids and proteins by using principal component analysis-linear discriminant analysis (PCA-LDA) on 3D rendered MSI volume data from MDA-MB-231-HRE-tdTomato breast tumor xenografts. In this study, we identified hypoxia-regulated proteins active in several distinct pathways such as glucose metabolism, regulation of actin cytoskeleton, protein folding, translation/ribosome, splicesome, the PI3K-Akt signaling pathway, hemoglobin chaperone, protein processing in endoplasmic reticulum, detoxification of reactive oxygen species, aurora B signaling/apoptotic execution phase, the RAS signaling pathway, the FAS signaling pathway/caspase cascade in apoptosis, and telomere stress induced senescence. In parallel, we also identified colocalization of hypoxic regions and various lipid species such as PC(16:0/18:0), PC(16:0/18:1), PC(16:0/18:2), PC(16:1/18:4), PC(18:0/18:1), and PC(18:1/18:1), among others. Our findings shed light on the biomolecular composition of hypoxic tumor regions, which may be responsible for a given tumor's resistance to radiation or chemotherapy.

Abstract
OBJECTIVE To study the clinicopathologic characteristics of primary renal hemangioblastoma. METHODS The morphologic features, immunophenotype and molecular findings of 3 cases of primary renal hemangioblastoma were studied, with review of literature. RESULTS The age of patients ranged from 43 to 57 years. There were 2 women and a man. The patients often presented with renal mass. Histologically, the tumors were surrounded by thick fibrous capsule and composed of epithelioid or spindle cells. Two cases had a prominent stromal component and the other one was rich in capillary network. Lipid vacuoles were observed in all cases. Features of hemorrhage were demonstrated in 2 cases. Capsular invasion and necrosis were seen in 1 case. Immunohistochemical study showed that the stromal cells were positive for alpha-inhibin (3/3), S-100 protein (3/3), EGFR (2/2), PAX-2 (2/2), PAX-8 (2/2) and CA9 (2/2) but negative for CKpan (2/2) and HMB45 (2/2). Focal membranous staining for CD10 (3/3) was noted. No VHL gene mutations or chromosome 3p deletion were detected in the 2 cases studied. CONCLUSIONS Renal hemangioblastoma shows distinctive morphologic appearance with a wide range of variation. The unexpected positive staining for PAX-2, PAX-8 and CD10 in renal hemangioblastoma needs to be aware. Immunohistochemical study may be helpful in differential diagnosis of these renal tumors.

Abstract
OBJECTIVE To study the clinicopathologic features of clear cell papillary renal cell carcinoma (CCPRCC). METHODS The clinical, morphologic and immunohistochemical characteristics of 6 cases of CCPRCC were reviewed, with analysis of follow-up data. RESULTS There were altogether 3 men and 3 women. The mean age of patients was 56 years. The size of tumors ranged from 1.0 to 4.5 cm in greatest dimension. They had solid or solid-cystic cut surface. Histologically, the tumors were encapsulated and showed several morphologic patterns, with tubules, papillae, acini, interconnecting ribbons and macro/microcysts lined by single layer of cells with clear or small amount of eosinophilic cytoplasm and low-grade nuclei (corresponding to Fuhrman grade 1 or 2). Mitotic figures were rarely seen. Characteristically, there was linear arrangement of the nuclei away from the basement membrane, conferring an appearance similar to that of endometrial glands in early secretory phase. Tubules and cysts contained serosanguineous fluid or colloid-like secretion were identified. No foamy histiocytes, psammomatous calcifications or hemosiderin was present in the papillary areas. Two of the tumors showed focal or extensive angioleiomyoma/leiomyoma-like components. No coagulative necrosis, sarcomatoid dedifferentiation, nor microscopic vascular invasion was observed. Immunohistochemically, all tumors showed strong co-expression of CK7 and CA9 (with characteristic "goblet" staining pattern). The staining for EMA, CK (AE1/AE3), vimentin, CK8, CK18, CK19 and PAX-8 were also positive in all cases. Ki-67 was expressed in less than or about 5% of the tumor cell nuclei. The staining for CD10, P504S, CD117, TFE3 and TFEB was negative. Follow-up data were available in all patients, with mean duration of 14 months (range = 7 to 27 months). All of the patients were disease-free after operation. CONCLUSION CCPRCC is a special type of low-grade renal neoplasm with characteristic histopathologic and immunohistochemical features. It needs to be distinguished from clear cell renal cell carcinoma or papillary renal cell carcinoma.

Abstract
BACKGROUND The Leukemia related protein 16 gene (LRP16) localized on chromosome 11q12.1, is an important estrogen-responsive gene and a crucial regulator for NF-kB activation. LRP16 is frequently expressed in human cancers; however, the LRP16 gene remains unexplored in lung neuroendocrine tumors. The aim of this study was to investigate the role of LRP16 expression in primary lung neuroendocrine tumors. METHODS lung neuroendocrine tumors were analyzed for LRP16 gene expression by two-step non-biotin immunohistochemical method. RESULTS Fifty of ninety (55.6%) cases of neuroendocrine lung tumors tested were positive for LRP16 protein by immunohistochemistry. The expression of LRP16 was mainly located in cytoplasm and nucleus of tumor cells. LRP16 protein was corresponding to tumor type and clinical stage, as well as survival time. CONCLUSIONS The results indicate that abnormal LRP16 expression is noted in neuroendocrine lung tumors and the expression can give insight into the pathogenesis of the disease. The LRP16 protein may serve as a potential marker in predicting prognosis of neuroendocrine lung tumors.

Abstract
AIM Endothelin-1 is an autocrine growth factor for keratinocytes, an effect controlled by its A and B receptors, with no previous comparison of endothelin axis expression in inflammatory and neoplastic skin diseases showing keratinocyte proliferation. The aim of the study was to investigate endothelin-1 axis expression in skin lesions of psoriasis, basal cell carcinoma (BCC), and squamous cell carcinoma (SCC). METHODS This study included 40 subjects (8 patients with SCC, 12 patients with BCC, 10 patients with psoriasis, and 10 healthy controls). Biopsies from lesional skin of patients and normal skin of controls were examined immunohistochemically for endothelin-1 and its receptors A and B frequency and grade of expression. RESULTS Endothelin-1 and receptor A were detected in all patients with SCC and psoriasis, with a higher frequency and grade of expression than controls and BCC. The frequency of receptor B expression was significantly lower while higher staining grade was found in BCC (8.3%) rather than other studied groups. CONCLUSION A comparable higher frequency and grade of expression of endothelin-1 and its receptor A are documented in psoriasis and SCC than in BCC and controls denoting their involvement in keratinocyte proliferation in both diseases. Receptor A is the predominately expressed receptor in psoriasis and SCC.

Abstract
The differential diagnosis between atypical leiomyoma and leiomyosarcoma may be hard based on morphological criterion at times. It would be helpful to find out biomarkers that can be used to distinguish them. The aim of the study was to investigate the diagnostic value of progesterone receptor (PR), p16, p53 and pHH3 expression in a series of uterine smooth muscle tumors. Immunohistochemical expression of PR, p16, p53 and pHH3 was investigated on 32 atypical leiomyomas, 15 leiomyosarcomas and 15 usual leomyomas. The difference in expression was compared between atypical leiomyoma and other groups. The expression of PR, p16, and pHH3 was found significantly different between atypical leiomyomas and leiomyosarcomas, but lack of significant difference between atypical leiomyomas and usual leiomyomas. There was no significant difference with regard to p53 distribution among these uterine smooth muscle tumors. High p16, pHH3 expression and low PR expression preferred the diagnosis of leiomyosarcoma. The panel of antibodies used in this study is a useful complementary analysis in the assessment of problematic uterine smooth muscle tumors.

Abstract
AIMS AND BACKGROUND The molecular mechanisms involved in resistance to 5-fluorouracil (5-FU) in colon cancer patients remain to be elucidated. The purpose of this study was to identify proteins associated with 5-FU resistance in colon cancer. METHODS AND STUDY DESIGN Proteins secreted from a 5-FU-resistant human colon cancer cell line (SNU-C4 5-FU 200) were analyzed by two-dimensional gel electrophoresis-based proteomics, and identified using matrix-associated laser desorption/ionization-mass spectroscopy analysis and SWISS-PROT database searches. The expression levels of candidate proteins were determined by Western blotting and cell proliferation was monitored by MTT assay. RESULTS Chaperonin 10 (cpn10) was secreted at a lower level by 5-FU-resistant cells compared to the non-resistant parent cell line. The proliferation of both the parent and 5-FU-resistant cell lines increased slightly when extracellular cpn10 alone was added. However, in the presence of 5-FU, cpn10 augmented 5-FU-induced apoptotic death in both cell lines. Cpn10 led to activation of extracellular signal-regulated kinase 1/2 (ERK 1/2), and a specific ERK 1/2 inhibitor, PD98059, completely inhibited cpn10-stimulated cell proliferation. CONCLUSIONS Our findings indicate that concurrent treatment with cpn10 and 5-FU warrants further investigation in an effort to overcome 5-FU resistance and enhance the efficacy of 5-FU therapy for colon cancer.

Abstract
The aim of this study is to determine the expression level of spindle assembly checkpoint (SAC) proteins-BubR1 and synuclein-gamma (SNCG) in human breast cancer tissues and to test whether there is a relationship between their expression levels and clinicopathologic parameters including respons to taxanes, tumor grade, estrogen receptor (ER) pozitivity, HER2 status, and overall survival (OS). We analyzed retrospectively paraffin-embedded tissue sections from 55 breast cancer patients whose clinical outcomes had been tracked after taxane treatment in neoadjuvan and metastatic setting. The expression status of BubR1 and SNCG was defined by immunohistochemistry (IHC) using the anti-BubR1 and anti-SNCG antibody. The BubR1 and SNCG was overexpressed in 38% and 62% of the study group, respectively. There was borderline significant correlation between low BubR1 expression and increased taxane sensitivity (P=0.05). In contrast, high SNCG expression was significantly associated with decreased taxane sensitivity (P=0.01). There was no association between the clinicopathologic parameters including histologic grade, ER positivity and HER2 status and the level of these proteins. However, triple negative tumors showed significantly more high BubR1 expression than those other molecular subtypes (P=0.04). Kaplan-Meier survival analysis failed to show a significant correlation between expression levels of BubR1 and SNCG and overall survival although patients with low levels of both proteins had a marginally longer survival time compared to those with high levels. In summary, our data suggest that both BubR1 and SNCG may be promising predictive marker rather than prognostic marker in patients with breast cancer.

Abstract
We report a case of Peutz-Jeghers syndrome (PJS) in a 33-year-old female patient with synchronous uterine cervical minimal deviation adenocarcinoma (MDA) and gastric type adenocarcinoma (GTA). The patient was diagnosed with PJS at the age of 10. At the time of consultation, she complained of watery discharge. Magnetic resonance imaging of the pelvis showed a poorly circumscribed mass in the uterine cervix. Histologically, both MDA and GTA components, as well as their transitional area, were observed. Both components were diffusely positive for MUC6, CK7 and, robustly, for p16. Moreover, the components were negative for ER, PgR and CEA, while HIK1083 and CK20 positive cells were found focally. Ki-67 labeling index in the MDA component was 5% while that in the GTA component was 50%. This case of GTA accompanied by MDA in a patient with PJS is distinct from the single previously-reported comparable case of which we are aware, with respect to the overexpression of p16 protein, an event considered rare in these tumors, and the continuity between the MDA and GTA components. This continuity favors the hypothesis that GTA arises from the dedifferentiation of MDA.

Abstract
We report herein a case of a 65-year-old male with intracranial recurrence of atypical meningioma initially treated with a combination of surgical resection and gamma knife radiotherapy. Afterwards, he underwent a (68)Ga-DOTANOC PET/CT scan in order to evaluate the feasibility of peptide receptor radionuclide therapy (PRRT). The scan identified multiple pulmonary, pleural and lymph node localizations. Histological diagnosis was consistent with intracranial atypical meningioma with diffuse metastatic spread. In our case, we have shown that meningioma with extracranial locations may present high uptake of somatostatin receptor analogues. Among other radionuclides, we believe that (68)Ga-DOTANOC PET/CT may be particularly useful for staging, detection of recurrence, evaluation of disease extension and alternative therapeutic approaches.

Abstract
INTRODUCTION Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. Numerous studies have reported the association between GIST and other neoplasms. OBJECTIVES The aim of this study was to investigate the possible association between GIST and other tumors in a genetically isolated population. METHODS A retrospective study was conducted of patients with GIST between 2002 and 2009 at our center. Epidemiological, pathological and family data in patients with GIST alone (group A) were compared with those in patients with GIST associated with other neoplasms (group B). A possible common genetic mechanism was investigated between GIST and associated malignancies by testing the detection of the immunohistochemical marker, CD117, in all tumors. RESULTS Twenty-two patients with GIST were identified, 10 in group A (45%) and 12 in group B (55%). In group B, the associated tumor was malignant in 6 patients (50%) and benign in another 6 (50%). Of the 22 patients with GIST, 8 (36%) had a family history of malignancies. Of these 8 patients, 7 (87.5%) were in group B (p=0.03) and 3 (37.5%) showed the same pathological type of neoplasm as their relatives. All GIST were positive for CD117 whereas associated malignancies were negative for this marker. CONCLUSION We did not find immunohistochemical positivity for CD117 in malignancies associated with GIST. Given the special characteristics of the study population, the association between GIST and associated malignancies may be incidental.

Abstract
Retinoblastoma is a commonly seen and dangerous intraocular malignant tumor in infants. Studies have found that Claudin-1 and MMP-2, whose expressions may be connected, play roles in tissues of retinoblastoma. In this study we analyze and discuss changes of Claudin-1 and MMP-2 expressions, and the correlation between the expressions and retinoblastoma histological differentiation and optic nerve invasion. MaxVisionTM was applied to detect expressions of Claudin-1 and MMP-2 in 45 samples of retinoblastoma and 15 paraffin-embedded samples of normal retina. The correlation between Claudin-1 expression and MMP-2 expression was analyzed based on chi-squared test and Spearmans correlation test. Positive expressions of Claudin-1 in retinoblastoma were fewer than those in retina; higher positive expressions were found in differentiated tissues than in undifferentiated tissues; while compared to expressions in invasive optic nerves, Claudin-1 expressed more positively in optic nerves without invasion. As for MMP-2, its expressions were higher in retinoblastoma than in normal retina; undifferentiated tissues had higher positive expressions than differentiated tissues, which were not statistically significant; higher positive expressions were detected in invasive optic nerves. Thus, it could be concluded that the correlation between Claudin-1 expression and MMP-2 expression in retinoblastoma was negative. Expressions of Claudin-1 were positively related to histological differentiation and optic nerve invasion of retinoblastoma; while MMp-2 expression had negative correlation with histological differentiation and optic nerve invasion of retinoblastoma. Claudin-1 and MMP-2 played a negative role in the optic nerve invasion and tumor development of retinoblastoma.

Abstract
BACKGROUND Mesenchymal Gastrointestinal (GI) tumours are heterogenous group of tumours. Prior to 2005, immunohistochemistry (IHC) was not used in diagnostic pathology to characterize these tumours at our centre. OBJECTIVES To subclassify mesenchymal tumours in the GI tract and related locations into Gastrointestinal stromal tumour (GIST) and non-GIST tumours using specific IHC antibody markers. METHODS Formalin Fixed Paraffin Embedded tumour tissue over the period 1991- 2004 were retrieved, from the files and records of the Department of Pathology, University College Hospital, Ibadan, Nigeria. Haematoxylin and Eosin slides of such cases were reviewed. The IHC expressions of c-Kit, CD 34, α-smooth muscle actin, desmin and S-100 were evaluated in these tumours. RESULTS Based on morphology and IHC staining pattern, 24 of the 46 cases were identified as GIST by c-kit positivity. Nine of the cases were smooth muscle tumours (4- leiomyoma and 5- leiomyosarcoma), 8 cases of undifferentiated sarcomas, 4 cases of desmoid and one case of inflammatory myofibroblastic tumour. For GISTs: The male:female ratio is 1.2. The age range of the patients was 11-75 years with a mean age of 55.1 years.Tumour size ranged from 7-32 cm with an average of 19.8cm and average mitotic count of 20 per 50 high power field. The location of the GIST tumours were as follow- stomach- 9 cases (37.5% of the 24 GIST cases), colon and rectum -6 (25%), Abdominal cavity (omentum/ mesentery)- 6 (25%), retroperitoneum-2(8.3%), small intestine-1 (4.2%). CONCLUSION The use of IHC in this study has helped to segregate and distinguish GI mesenchymal tumours into different sub-types, majority being Gastrointestinal stromal tumours.

Abstract
In the early stages, prostate cancer is androgen‑ dependent; therefore, medical castration has shown significant results during the initial stages of this pathology. Despite this early effect, advanced prostate cancer is resilient to such treatment. Recent evidence shows that derivatives of Cannabis sativa and its analogs may exert a protective effect against different types of oncologic pathologies. The purpose of the present study was to detect the presence of cannabinoid receptors (CB1 and CB2) on cancer cells with a prostatic origin and to evaluate the effect of the in vitro use of synthetic analogs. In order to do this, we used a commercial cell line and primary cultures derived from prostate cancer and benign prostatic hyperplasia. The presence of the CB1 and CB2 receptors was determined by immunohistochemistry where we showed a higher expression of these receptors in later stages of the disease (samples with a high Gleason score). Later, treatments were conducted using anandamide, 2-arachidonoyl glycerol and a synthetic analog of anandamide, methanandamide. Using the MTT assay, we proved that the treatments produced a cell growth inhibitory effect on all the different prostate cancer cultures. This effect was demonstrated to be dose-dependent. The use of a specific CB1 receptor blocker (SR141716) confirmed that this effect was produced primarily from the activation of the CB1 receptor. In order to understand the MTT assay results, we determined cell cycle distribution by flow cytometry, which showed no variation at the different cell cycle stages in all the cultures after treatment. Treatment with endocannabinoids resulted in an increase in the percentage of apoptotic cells as determined by Annexin V assays and caused an increase in the levels of activated caspase-3 and a reduction in the levels of Bcl-2 confirming that the reduction in cell viability noted in the MTT assay was caused by the activation of the apoptotic pathway. Finally, we observed that endocannabinoid treatment activated the Erk pathway and at the same time, produced a decrease in the activation levels of the Akt pathway. Based on these results, we suggest that endocannabinoids may be a beneficial option for the treatment of prostate cancer that has become nonresponsive to common therapies.

Abstract
C-erbB-2 is a cancer gene originating from cells. The high-expression and amplification of C-erbB-2 and its protein products (P185) are found in a wide variety of tumors. The abnormal expression of C-erbB-2 has great influence on the occurrence and development of gastric carcinoma. This paper aimed to analyze the expression of C-erbB-2 in the tissues of gastric carcinoma, gastric mucosal atypical hyperplasia and gastritis, and discuss its role in the occurrence and development of gastric carcinoma. The morphological differences and connections among simple intestinal metaplasia (SIM), atypical intestinal metaplasia (AIM) and dysplasia in intestinal metaplasia through hematoxylin and eosin (HE) staining were studied. Three groups were set to detect the expression condition of C-erbB-2 by immunohistochemical method (IHC). The result showed that C-erbB-2 had no significant difference in AIM and gastric carcinoma, that is, AIM was closely related to gastric carcinoma. The positive expression was demonstrated of C-erbB-2 products (P185) in medium and gastric mucosa dysplasia tissues and was 29.41% and 66.67%, respectively, while it was 25%, 50% and 77.78% in high, medium and low differentiation of gastric carcinoma. It can be seen that there was a significant difference between them (P<0.05), and the expression degree was significantly enhanced (P<0.05); the expression degree in high differentiation gastric cancer tissue was significantly higher than the middle and low differentiation gastric cancer tissue. It was concluded that C-erbB-2 played an important role in the pathogenic mechanism of gastric carcinoma, and it might act on the later period of the gastric carcinoma, which provides objective reference index for the diagnosis and prognosis of gastric carcinoma and meanwhile provides instructional theoretical reference for the application of targeted drugs in the clinical treatment of gastric carcinoma.

Abstract
AHNAK is a 700 KD phosphoprotein primarily involved in calcium signaling in various cell types and regulating cytoskeletal organization and cell membrane architecture. AHNAK expression has also been associated with obesity. To investigate the role of AHNAK in regulating metabolic homeostasis, we studied whole body AHNAK knockout mice (KO) on either regular chow or high-fat diet (HFD). KO mice had a leaner phenotype and were resistant to high-fat diet-induced obesity (DIO), as reflected by a reduction in adipose tissue mass in conjunction with higher lean mass compared to wild-type controls (WT). However, KO mice exhibited higher fasting glucose levels, impaired glucose tolerance, and diminished serum insulin levels on either diet. Concomitantly, KO mice on HFD displayed defects in insulin signaling, as evident from reduced Akt phosphorylation and decreased cellular glucose transporter (Glut4) levels. Glucose intolerance and insulin resistance were also associated with changes in expression of genes regulating fat, glucose, and energy metabolism in adipose tissue and liver. Taken together, these data demonstrate that (a) AHNAK is involved in glucose homeostasis and weight balance (b) under normal feeding KO mice are insulin sensitive yet insulin deficient; and (c) AHNAK deletion protects against HFD-induced obesity, but not against HFD-induced insulin resistance and glucose intolerance in vivo.

Abstract
BACKGROUND Lymph node metastasis is an important clinicopathological parameter for breast cancer prognostication and treatment. Although the development of metastasis is common in axillary lymph nodes, the mechanisms underlying the locoregional spread are yet poorly understood. In the present study, we outline the involvement of proteins in tumor invasion by comparing the proteome profile of primary breast tumors (PBT) against that of lymph node metastasis (LNM). PATIENTS AND METHODS The comparative proteome analyses of seven paired samples were performed using two-dimensional gel electrophoresis (2DE) and mass spectrometry (MS). RESULTS Recurrent proteins were differentially expressed in PBT and LNM across patients. Higher levels of 1433G, 1433T, K2C8, PSME2, SNAA, TPM4, TRFE and VIME were observed in primary tumors compared to the metastatic site. On the other hand, higher levels of ALDH2 and GDIR2 were identified in metastasis related to tumors. These proteins provide a new insight on breast cancer research. CONCLUSION Our achievements strengthened previous omics-based studies and also support the validation of potential markers of tumor invasion and metastasis.

Abstract
We have recently applied the technique of drop coating deposition Raman (DCDR) spectroscopy for colorectal cancer (CRC) detection using blood plasma. The aim of this study was to develop a more convenient and stable method based on blood plasma for noninvasive CRC detection. Significant differences are observed in DCDR spectra between healthy (n = 105) and cancer (n = 75) plasma from 15 CRC patients and 21 volunteers, particularly in the spectra that are related to proteins, nucleic acids, and β-carotene. The multivariate analysis principal components analysis and the linear discriminate analysis, together with leave-one-out, cross validation were used on DCDR spectra and yielded a sensitivity of 100% (75/75) and specificity of 98.1% (103/105) for detection of CRC. This study demonstrates that DCDR spectroscopy of blood plasma associated with multivariate statistical algorithms has the potential for the noninvasive detection of CRC.

Abstract
To research the expression in human lung adenocarcinoma tissue of Cripto-1 (teratocarcinoma derived growth factor-1) gene protein and Activin-A gene protein, and explore the relationship and clinical significance between the two gene protein and clinical pathological characteristic of lung adenocarcinoma. This study had applied the immunohistochemical method to detect the 188 cases of lung adenocarcinoma and expression of Cripto-1 protein and Activin-A protein in 100 cases of normal lung tissue. Then, analysis the relationship between these two-gene protein and clinical lung adenocarcinoma histopathological features, and inherent correlation between these two genes. The positive expression rate of Cripto-1 protein in lung adenocarcinoma tissue was significantly higher in normal lung tissue, while, the positive expression rate of Activin-A protein in lung adenocarcinoma tissue was significantly lower than in normal lung tissue. The high expression of Cripto-1 and low expression of Activin-A was closely related (each P<0.05) to the TNM staging of lung adenocarcinoma, lymph node metastasis and the main pathological tissue staging of lung adenocarcinoma. And the correlation analysis showed that it was negative correlation for the expression of Activin-A protein and Cripto-1 protein in lung adenocarcinoma. The over expression of Cripto-1 and the expression lack of Activin-A were correlated with the occurrence, development, metastasis and malignant degree of lung adenocarcinoma.

Abstract
Colorectal cancer is the leading cause of cancer-related death in women and third leading cause of death in men. The prognosis worsens when cancer metastasizes to other organs. Thus, there is an urgent need to develop biomarkers for the early diagnosis of metastasis as well as cancer development. Mass spectrometry-based technologies have been applied to the discovery of protein biomarkers, especially in the field of cancer. These results have identified numerous candidate protein biomarkers. Unfortunately, only a few are currently being applied in clinical diagnostics. Recent advances in proteomic technology such as selected/multiple reaction monitoring (SRM/MRM) facilitated the detection and quantitation of specific proteins in complex samples without the need for antibodies. We performed a quantitative proteomic analysis of membrane proteins extracted from colorectal cancer tissues using the iTRAQ shotgun method to discover biomarker candidates, and then extensively validated the biomarker candidate proteins by SRM/MRM. A total of 5,566 proteins were identified in tissue samples obtained from adenoma and cancer with and without metastasis. Differences were observed in the expression of about 400 proteins. Among them, 105 biomarker candidates which were predicted to be membrane proteins and extracellular proteins by gene ontology analysis were quantitated using SRM/MRM. As a result, we could confirm differences in the expressions of 69 of these proteins using the same set of patient samples as discovery experiments, and this was subsequently verified in an independent set of samples. Significant differences were observed in the expression of 44 of these proteins. Moreover, some of the biomarker candidates were detected and quantitated in the serum of colorectal cancer patients. These biomarker candidates are promising diagnostic tools on investigating the development and progression of colorectal cancer.

Abstract
The fecal occult blood test (FOBT) is widely used for colorectal cancer (CRC) screening to reduce the mortality rate associated with this cancer. However, several problems exist, as FOBT results can contain some false-negative CRC patients and some-false positive healthy subjects. Thus, to resolve these problems, several fecal biomarkers based on fecal protein, fecal DNA, and fecal RNA have been reported. Fecal calprotectin, which indicates intestinal bleeding or inflammation of the colon mucosa, and fecal tumor M2-PK, which is produced by cancer cells, have been extensively investigated as fecal protein biomarkers. To detect small amounts of CRC-specific proteins, the chemiluminescent enzyme immunoassay (CLEIA), which is a highly sensitive protein detection method using immunomagnetic beads, will be used. DNA mutation of APC, KRAS, and TP53 genes and DNA methylation of VIM, TFPI2, BMP3, NDRG4, and SFRP2 genes were reported as fecal DNA biomarkers. Consequently, a fecal DNA test named Cologuard from Exact Sciences was approved by the FDA in August 2014. Fecal COX2, MMP7, miR-106a, miR-92a, and miR-223 were also reported as fecal RNA biomarkers. This review article summarizes fecal biomarkers using fecal samples for CRC diagnosis.

Abstract
PURPOSE Thyroid tumors of uncertain malignant potential (TT-UMP) constitute a relatively new diagnosis. The purpose of this study was to analyze the relationship between immunohistochemical panels, prognostic parameters and TT-UMP. METHODS Group I was composed of patients diagnosed as differentiated thyroid carcinoma (DTC) and Group II of patients diagnosed as TT-UMP. The prognostic scores of patients were calculated using data according to the well-known prognostic scoring systems MACIS, AMES, AGES. Evaluations of antibodies were based on the presence of nuclear staining for p16 and p53, membranous and cytoplasmic staining for epidermal growth factor receptor (EGFR) and cytoplasmic staining for fragile histidine triad (FHIT). RESULTS Statistically significant difference was noted (p< 0.05) between Group I and Group II according to MACIS and AMES. No statistical difference was found in terms of immunostaining between groups when stained with p16, p53 and FHIT. On the other hand, in Group II a moderate positive correlation was detected between MACIS and EGFR. CONCLUSION According to our findings p53 was not important in tumor genesis at early stages in well-differentiated thyroid carcinomas and p16 loss of expression could be used as a finding to help in difficult microscopic diagnosis. TT-UMP is a gray zone of lesions requiring specific therapeutic procedures and postoperative follow-up. A positive correlation was detected between EGFR and TT-UMP, leading to assume that this situation could be used as a new tool in the follow-up of these patients in the future.

Abstract
Human saliva is rich in proteins, which have been used for disease detection such as oral diseases and systematic diseases. In this paper, we present a computational method for predicting secretory proteins in human saliva based on two sets of human proteins from published literatures and public databases. One set contains known proteins which can be secreted into saliva, and the other contains the proteins that are deemed to be not extracellular secretion. The protein features with discerning power between two sets were firstly gathered. Then a classifier was trained based on the identified features to predict whether a protein was saliva-secretory one or not. The average values of the sensitivity, specificity, precision, accuracy, and Matthews correlation coefficient value by 10-fold cross validation repeated 100 times were 80.67%, 90.56%, 90.09%, 85.53%, and 0.7168, respectively. These results indicated that our selected features are informative. We applied the classifier for prediction saliva-secretory proteins out of all human proteins, if a known biomarker was likely to enter into saliva, and the potential salivary biomarkers for head and neck squamous cell carcinoma. We also compared the top 1000 proteins predicted by computational methods in different kind of fluids. This work provided a useful tool for effectively identifying the salivary biomarkers for various human diseases and facilitate the development of salivary diagnosis.

Abstract
BACKGROUND This study investigated the correlation between cervical cytology, the expression of P16INK4a, and human papilloma virus (HPV) infection. MATERIALS AND METHODS The study included 100 subjects with suspected pathological cervical lesions. Cervical smears were analyzed for malignancy and p16INK4a. Histological finding represented "the golden standard". RESULTS Immunocytochemical analysis of protein p16INK4a expression on epithelial cells of cervical smear demonstrated increased p16lNK4a expression in 36.0% of subjects. There was statistically significant positive correlation (Spearman r = 0.70; p < 0.001) between the pathological findings and the intensity of p16INK4a protein expression inside the epithelial cells, as well as with the histological finding (Spearman r = 0.71; p < 0.001). The intensity of p16INK4a protein expression in cytology finding was significantly higher in HPV16 positive patients (Mann- Whitney test, p = 0.0065). CONCLUSION Good correlation between the expression rate and the severity of lesions indicates that this test might improve the results of cytology and HPV screening, as well as the results of predicting the prognosis of the disorder of the cervix.

Abstract
It is now possible to identify several key factors that determine biological characteristics of squamous cell cancer of the head and neck: genes p53, p16, cyclin D1, P13-K/Akt connected with metastasis proteins (proteases, proteins mesenchymal cells, cell adhesion molecules chemokines), angiogenesis factors (VEGF, PDGF, FGF, TGF-alpha and TGF-beta), IL-8; epidermal growth factor receptors. An important role of tumor cells plays microenvironment. Of course the above mentioned is only a small part of the factors that determine the livelihoods and the activity of cancer cells. All of these factors are potential predictors of the effectiveness of radiation and chemoradiation treatment and actively studied in recent decades.

Abstract
The aim of the present study was to investigate the subcellular localization of proteins participating in the double-strand break response pathway - p53, Mdm2, p21 and Chk2. MOLT-4 cells were pre-treated with mitoxantrone in concentrations 1 nmol/l and 5 nmol/l. The trypan blue technique was used to determine cell viability and proliferation. Western blotting was used to evaluate changes in p53, Mdm2 and Chk2 protein expression and sandwich ELISA was used to evaluate changes in the p21 protein amount. After 1 nmol/l mitoxantrone cells did not die, but their ability to proliferate was decreased. The p53 protein was activated and phosphorylated at serines 15 and 392 and accumulated in the nucleus after 24 and 48 h. The Mdm2 protein was present in the cytoplasm with its maximal level after 8 and 16 h. The p21 protein was detected in the nucleus after 24 and 48 h. Increased levels of phosphorylated Chk2 at threonine 68 were observed in the cytoplasmic fraction after 24 and 48 h of mitoxantrone treatment. We used mitoxantrone as an inducer of double-strand breaks to bring new data about the subcellular distribution of proteins responding to DNA damage. In MOLT-4 cells, the p53 protein was activated. p53 was phosphorylated at serines 15 and 392 and accumulated in the nucleus. The Mdm2 protein was activated in advance to p53 and occurred in the cytoplasm. The p21 protein was present in the nucleus. Chk2 kinase was activated by the phosphorylation at threonine 68 and we observed increased levels of this protein in the cytoplasmic fraction.

Abstract
Soft tissue tumors are rare tumors that show a heterogeneous structure; thus far, their molecular behavior has not been elucidated.

Immunostains were done in 55 cases consisting of benign and malignant tumors, such as liposarcomas, dermatofibrosarcomas, and tumors with histiocytic differentiation. Renal tubes were used as external control for VEGF, maspin, and DOG-1. Although DOG-1 is considered a specific marker for gastrointestinal tumors (GISTs), its positivity, correlated with c-KIT and VEGF immunoexpression, was also shown by dermatofibrosarcomas and tumors with histiocytic and lipomatous differentiation, suggesting its possible pro-angiogenic role. Maspin expression was observed in adipose tissue tumors only. Regarding angiogenesis, 31 of the 55 cases were VEGF-positive, such positivity being directly correlated with COX-2 and CD34 positivity as evaluated in the tumor cells and also with MVD. Although no significant differences in angiogenic activity were found between benign and malignant non-lipomatous tumors, the MVD was directly correlated with the histological type/grade of liposarcomas. Based on these aspects, we conclude that VEGF/COX-2-induced angiogenesis is specific for non-lipomatous tumors, whereas liposarcomas are dependent on the VEGF/maspin angiogenic pathway. The DOG-1/c-KIT/VEGF target may be used for further personalized therapy of soft tissue sarcomas. No data about DOG-1 and maspin positivity in liposarcomas have been published to date.

Abstract
The S100P protein stimulates cell proliferation and survival, thereby contributing to tumor progression. The purpose of this study was to evaluate S100P expression in the three subtypes of mucinous cystic tumors, cystadenomas, borderline tumors, and adenocarcinomas. The authors examined nuclear S100P expression in 60 mucinous ovarian tumor specimens, including 24 specimens of mucinous cystadenoma, 15 of borderline tumors, and 21 of adenocarcinomas. Immunohistochemistry revealed S100P expression followed one of three patterns: (1) Expressed in most nuclei of mucinous epithelial cells, (2) sporadic (spotted or patchy) expression, or (3) absent or rarely expressed in the nuclei of mucinous epithelial cells. Most adenomas showed the first expression pattern, and borderline tumors often showed a patchy expression pattern. Adenocarcinomas generally demonstrated absence of S100P expression. These data suggest that S100P is a useful histological marker to differentiate between benign, borderline, and malignant mucinous tumors of the ovary.

Abstract
We studied the effect of ellagic acid (EA) on the morphology of nucleoli and on the pattern of major proteins of the nucleolus. After EA treatment of HeLa cells, we observed condensation of nucleoli as documented by the pattern of argyrophilic nucleolar organizer regions (AgNORs). EA also induced condensation of RPA194-positive nucleolar regions, but no morphological changes were observed in nucleolar compartments positive for UBF1/2 proteins or fibrillarin. Studied morphological changes induced by EA were compared with the morphology of control, non-treated cells and with pronounced condensation of all nucleolar domains caused by actinomycin D (ACT-D) treatment. Similarly as ACT-D, but in a lesser extent, EA induced an increased number of 53BP1-positive DNA lesions. However, the main marker of DNA lesions, γH2AX, was not accumulated in body-like nuclear structures. An increased level of γH2AX was found by immunofluorescence and Western blots only after EA treatment. Intriguingly, the levels of fibrillarin, UBF1/2 and γH2AX were increased at the promoters of ribosomal genes, while 53BP1 and CARM1 levels were decreased by EA treatment at these genomic regions. In the entire genome, EA reduced H3R17 dimethylation. Taken together, ellagic acid is capable of significantly changing the nucleolar morphology and protein levels inside the nucleolus.

Abstract
Background The endothelium is not a homogeneous organ. Endothelial cell heterogeneity has been described at the level of cell morphology, function, gene expression, and antigen composition. As a consequence of the genetic, transcriptome and surrounding environment diversity, endothelial cells from different vascular beds have differentiated functions and phenotype. Detection of circulating endothelial cells (CECs) by flow cytometry is an approach widely used in cancer patients, and their number, viability and kinetic is a promising tool to stratify patient receiving anti-angiogenic treatment. Methodology/Principal Findings Currently CECs are identified as positive for a nuclear binding antigen (DNA+), negative for the pan leukocyte marker CD45, and positive for CD31 and CD146. Following an approach recently validated in our laboratory, we investigated the expression of CD109 on CECs from the peripheral blood of healthy subject and cancer patients. The endothelial nature of these cells was validated by RT-PCR for the presence of m-RNA level of CDH5 (Ve-Cadherin) and CLDN5 (Claudin5), two endothelial specific transcripts. Before treatment, significantly higher levels of CD109+ CECs and viable CD109+CECs were found in breast cancer patients and glioblastoma patients compared to healthy controls, and their number significantly decreased after treatment. Higher levels of endothelial specific transcripts expressed in developing endothelial cells CLEC14a, TMEM204, ARHGEF15, GPR116, were observed in sorted CD109+CECs when compared to sorted CD146+CECs, suggesting that these genes can play an important role not only during embryogenesis but also in adult angiogenesis. Interestingly, mRNA levels of TEM8 (identified as Antrax Toxin Receptor1, Antrax1) were expressed in CD109+CECs+ but not in CD146+CECs. Conclusion Taken together our results suggest that CD109 represent a rare population of circulating tumor endothelial cells, that play a potentially useful prognostic role in patients with glioblastoma. The role of CD109 expression in cancer vessel-specific endothelial cells deserves to be further investigated by gene expression studies.

Abstract
The endothelium is actively involved in many functions of the cardiovascular system, such as the modulation of arterial pressure and the maintenance of blood flow. These functions require a great versatility of the intracellular Ca2+ signaling that resides in the fact that different signals can be encoded by varying the frequency and the amplitude of the Ca2+ response. Cells use both extracellular and intracellular Ca2+ pools to modulate the intracellular Ca2+ concentration. In non-excitable cells, the inositol 1,4,5-trisphosphate receptor (IP3R), located on the endoplasmic reticulum (ER), is responsible for the release of Ca2+ from the intracellular store. The proteins STIM1 and STIM2 are also located on the ER and they are involved in the activation of a store-operated Ca2+ entry (SOCE). Due to their Ca2+ sensor property and their close proximity with IP3Rs on the ER, STIMs could modulate the activity of IP3R. In this study, we showed that STIM1 and STIM2 are expressed in bovine aortic endothelial cells and they both interact with IP3R. While STIM2 appears to play a minor role, STIM1 plays an important role in the regulation of agonist-induced Ca2+ mobilization in BAECs by a positive effect on both the SOCE and the IP3R-dependent Ca2+ release.

Abstract
OBJECTIVE Chemoresistance is a widespread therapeutic challenge in glial tumors. The molecular basis of chemoresistance is poorly understood, precluding advances in glioma treatment and leaving gliomas among the most lethal tumors. Oligodendrogliomas provide a unique model to study the molecular basis of chemoresistance, as there are two distinct genetic subtypes with significant differences in chemosensitivity. Despite a high morphological similarity, tumors with allelic loss on the short arm of chromosome 1 (1pLOH) are more chemosensitive than those without 1pLOH. METHODS In order to identify candidate proteins potentially responsible for glioma chemosensitivity, we compared the proteome of four oligodendrogliomas with and five without 1pLOH using comparative proteomic profiling. Proteomic analysis was performed by two-dimensional protein gel electrophoresis and subsequent computerized gel analysis for detection of distinguishing patterns of protein expression. Differentially expressed proteins were identified using Liquid Chromatography/Mass Spectrometry. Differential expression of select proteins was confirmed by Western blotting. RESULTS We identified seven candidate proteins that are overexpressed in oligodendrogliomas without 1pLOH. Two of these proteins (glyoxalase I and Rho GDP dissociation inhibitor) have previously been shown to enhance chemoresistance in other tumors. In turn, we identified twelve overexpressed proteins in tumors with 1pLOH that have previously been reported to induce chemosensitivity in other forms of human neoplasia. CONCLUSIONS These identified proteins are potential targets for pharmacological therapy and may also be useful as biomarkers for differentiation of chemoresistant and chemosensitive oligodendroglioma.

Abstract
PURPOSE Risk of cancer progression is reduced for patients with human papillomavirus (HPV) -positive oropharynx cancer (OPC) relative to HPV-negative OPC, but it is unknown whether risk of death after progression is similarly reduced. PATIENTS AND METHODS Patients with stage III-IV OPC enrolled onto Radiation Therapy Oncology Group trials 0129 or RTOG 0522 who had known tumor p16 status plus local, regional, and/or distant progression after receiving platinum-based chemoradiotherapy were eligible for a retrospective analysis of the association between tumor p16 status and overall survival (OS) after disease progression. Rates were estimated by Kaplan-Meier method and compared by log-rank; hazard ratios (HRs) were estimated by Cox models. Tests and models were stratified by treatment protocol. RESULTS A total of 181 patients with p16-positive (n = 105) or p16-negative (n = 76) OPC were included in the analysis. Patterns of failure and median time to progression (8.2 v 7.3 months; P = .67) were similar for patients with p16-positive and p16-negative tumors. After a median follow-up period of 4.0 years after disease progression, patients with p16-positive OPC had significantly improved survival rates compared with p16-negative patients (2-year OS, 54.6% v 27.6%; median, 2.6 v 0.8 years; P < .001). p16-positive tumor status (HR, 0.48; 95% CI, 0.31 to 0.74) and receipt of salvage surgery (HR, 0.48; 95% CI; 0.27 to 0.84) reduced risk of death after disease progression whereas distant versus locoregional progression (HR, 1.99; 95% CI, 1.28 to 3.09) increased risk, after adjustment for tumor stage and cigarette pack-years at enrollment. CONCLUSION Tumor HPV status is a strong and independent predictor of OS after disease progression and should be a stratification factor for clinical trials for patients with recurrent or metastatic OPC.

Abstract
In vitro expanded bone marrow stromal cells contain at least two populations of fibroblasts, a CD146/MCAM positive population, previously reported to be critical for establishing the stem cell niche and a CD146-negative population that expresses CUB domain-containing protein 1 (CDCP1)/CD318. Immunohistochemistry of marrow biopsies shows that clusters of CDCP1+ cells are present in discrete areas distinct from areas of fibroblasts expressing CD146. Using a stromal cell line, HS5, which approximates primary CDCP1+ stromal cells, we show that binding of an activating antibody against CDCP1 results in tyrosine-phosphorylation of CDCP1, paralleled by phosphorylation of Src Family Kinases (SFKs) Protein Kinase C delta (PKC-δ). When CDCP1 expression is knocked-down by siRNA, the expression and secretion of myelopoietic cytokines is increased. These data suggest CDCP1 expression can be used to identify a subset of marrow fibroblasts functionally distinct from CD146+ fibroblasts. Furthermore the CDCP1 protein may contribute to the defining function of these cells by regulating cytokine expression.

Abstract
Retroperitoneal leiomyosarcomas (LMSs) are rare gynecological malignancies that display poor prognosis and high mortality. Cell cycle-related and expression-elevated protein in tumor (CREPT) is an oncogene that is involved in the regulation of many cell cycle-related proteins. However, its distribution and clinical significance in retroperitoneal LMS remains poorly understood. This study assessed the histological classifications of postoperative tumor samples from 71 cases of retroperitoneal LMS that were collected at The General Hospital of the People's Liberation Army from January 1998 to December 2012. We found that more than half of the patients displayed positive expressions of CREPT, Ki-67 and PCNA via immunohistochemical analysis. The expression of CREPT correlated with histological grade (P = 0.044), and the PCNA expression level correlated with the differentiation of tumor cells and histological grade (P < 0.001 and P = 0.009, respectively). Multivariate analysis showed that survival was associated with histological grade and the expression level of CREPT (P = 0.011 and P = 0.012, respectively). Kaplan-Meier analysis showed that the patients lacking CREPT expression exhibited significantly longer overall postoperative survival (median, 60.0 months) than the patients displaying CREPT expression (median, 33.0 months), and CREPT expression correlated with distant recurrence within 5 years after surgery (P = 0.004). Western blot analyses showed that CREPT was more strongly expressed in the retroperitoneal LMS tumor tissue than in paired control tissue. Based on the above data, we concluded that CREPT displays unique immunostaining for retroperitoneal LMS tissue and can be used to supplement other currently available retroperitoneal LMS markers.

Abstract
BACKGROUND Melanoma-associated antigen (MAGE) family genes are reported to play important roles in the development of human cancers. However, the relationship between the expression of MAGE-A9 and clinicopathological characteristics in human laryngeal carcinoma remains unclear. This study aimed to examine the expression of MAGE-A9, and to evaluate the clinical significance of its expression in human laryngeal squamous cell carcinoma (LSCC). METHODS Quantitative real-time reverse transcription-PCR (qPCR) and immunohistochemistry (IHC) were performed to characterize the expression of MAGE-A9 in LSCC tissues and tumor-adjacent normal tissues. Kaplan-Meier survival and Cox regression analyses were performed to evaluate the prognosis of patients with LSCC. RESULTS The expression of MAGE-A9 was significantly higher in LSCC than in tumor-adjacent normal tissues. Cytoplasmic expression of MAGE-A9 was detected in 70 of 123 (56.9%) LSCC specimens. Levels of MAGE-A9 in LSCC were related to histopathological grade (P = 0.024). Kaplan-Meier survival and Cox regression analysis revealed that MAGE-A9 expression level and lymph node metastasis were independent prognostic factors of LSCC (P = 0.005; P = 0.001, respectively). CONCLUSIONS Our study suggests that MAGE-A9 expression is a prognostic biomarker for LSCC patients. High expression of MAGE-A9 indicates unfavorable survival outcome in LSCC patients.

Abstract
OBJECTIVES The purpose of the study was to detect the expression of SNCG, MAP2, SDF-1 and CXCR4 in gastric adenocarcinoma, and to evaluate their roles in the carcinogenesis of gastric adenocarcinoma, development, invasion and metastasis as well as their clinical significance. METHODS The expression of SNCG, MAP2, SDF-1 and CXCR4 was detected by SP immunohistochemical method in 225 cases of gastric adenocarcinoma and 105 cases of nonneoplastic adjacent gastric tissue. The expression of SNCG, MAP2, SDF-1 and CXCR4 mRNA was also detected by RT-PCR method in 50 cases of gastric adenocarcinoma and 30 cases of nonneoplastic adjacent gastric tissue. RESULTS The expression of SNCG, MAP2, SDF-1 and CXCR4 in the gastric adenocarcinoma was remarkably higher than those in the nonneoplastic adjacent gastric tissue (P < 0.01); The positive expression of SNCG and MAP2 was correlated with the depth of tumor invasion and the metastasis of lymph nodes (P < 0.05), and that of SDF-1 and CXCR4 was correlated with the metastasis of lymph nodes (P < 0.05). CONCLUSIONS SNCG, MAP2, SDF-1 and CXCR4 may play an important role in the carcinogenesis, progression, invasion and metastasis of gastric adenocarcinoma. However, it still needs more exploration whether they can serve as promising therapeutic targets of gastric adenocarcinoma.

Abstract
BACKGROUND Asthma is a complex disease influenced by multiple genetic and environmental factors. While Madeira has the highest prevalence of asthma in Portugal (14.6%), the effect of both genetic and environmental factors in this population has never been assessed. We categorized 98 asthma patients according to the Global Initiative for Asthma (GINA) guidelines, established their sensitization profile, and measured their forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) indexes. Selected single nucleotide polymorphisms (SNPs) were analysed as potential markers for asthma susceptibility and severity in the interleukin 4 (IL4), interleukin 13 (IL13), beta-2-adrenergic receptor (ADRB2), a disintegrin and metalloprotease 33 (ADAM33), gasdermin-like (GSDML) and the signal transducer and activator of transcription 6 (STAT6) genes comparatively to a population reference set. RESULTS Although mites are the major source of allergic sensitization, no significant difference was found amongst asthma severity categories. IL4-590*CT/TT and IL4-RP2*253183/183183 were found to predict the risk (2-fold) and severity (3 to 4-fold) of asthma and were associated with a lower FEV1 index. ADRB2-c.16*AG is a risk factor (3.5-fold), while genotype GSDML-236*TT was protective (4-fold) for moderate-severe asthma. ADAM33-V4*C was associated to asthma and mild asthma by the transmission disequilibrium test (TDT). Finally, ADAM33-V4*CC and STAT6-21*TT were associated with higher sensitization (mean wheal size ≥10 mm) to house dust (1.4-fold) and storage mite (7.8-fold). CONCLUSION In Madeira, IL4-590C/T, IL4-RP2 253/183, GSDML-236C/T and ADAM33-V4C/G SNPs are important risk factors for asthma susceptibility and severity, with implications for asthma healthcare management.

Abstract
During the past ten years, circulating tumour cells (CTCs) have received enormous attention as new biomarkers and the subject of basic research. Although CTCs are already used in numerous clinical trials, their clinical utility is still under investigation. Many issues regarding the detection and characterization of CTCs remain unknown. In this Opinion article, we propose a conceptual framework of CTC assays and point out current challenges of CTC research, which might structure this dynamic field of translational cancer research.

Abstract
The French-American-British (FAB) and WHO classifications provide important guidelines for the diagnosis, treatment, and prognostic prediction of acute leukemia, but are incapable of accurately differentiating all subtypes, and not well correlated with the clinical outcomes. In this study, we performed the protein profiling of the bone marrow mononuclear cells from the patients with acute leukemia and the health volunteers (control) by surface enhanced laser desorption/ionization-time of flight mass spectrometry (SELDI_TOF_MS). The patients with acute leukemia were analyzed as unitary by the profiling that were grouped into acute promyelocytic leukemia (APL), acute myeloid leukemia-granulocytic (AML-Gran), acute myeloid leukemia-monocytic (AML-Mon) acute lymphocytic leukemia (ALL), and control. Based on 109 proteomic signatures, the classification models of acute leukemia were constructed to screen the predictors by the improvement of the proteomic signatures and to detect their expression characteristics. According to the improvement and the expression characteristics of the predictors, the proteomic signatures (M3829, M1593, M2121, M2536, M1016) characterized successively each group (CON, APL, AML-Gra, AML-Mon, ALL) were screened as target molecules for identification. Meanwhile, the proteomic-based class of determinant samples could be made by the classification models. The credibility of the proteomic-based classification passed the evaluation of Biomarker Patterns Software 5.0 (BPS 5.0) scoring and validated application in clinical practice. The results suggested that the proteomic signatures characterized by different blasts were potential for developing new treatment and monitoring approaches of leukemia blasts. Moreover, the classification model was potential in serving as new diagnose approach of leukemia.

Abstract
Breast cancer is a heterogeneous disease, divisible into a variable number of clinical subtypes. A fundamental question is how many etiological classes underlie the clinical spectrum of breast cancer? An etiological subtype reflects a grouping with a common set of causes, whereas a clinical subtype represents a grouping with similar prognosis and/or prediction. Herein, we review the evidence for breast cancer etiological heterogeneity. We then evaluate the etiological evidence with mRNA profiling data. A bimodal age distribution at diagnosis with peak frequencies near ages 50 and 70 years is a fundamental characteristic of breast cancer for important tumor features, clinical characteristics, risk factor profiles, and molecular subtypes. The bimodal peak frequencies at diagnosis divide breast cancer overall into a "mixture" of two main components in varying proportions in different cancer populations. The first breast cancer tends to arise early in life with modal age-at-diagnosis near 50 years and generally behaves aggressively. The second breast cancer occurs later in life with modal age near 70 years and usually portends a more indolent clinical course. These epidemiological and molecular data are consistent with a two-component mixture model and compatible with a hierarchal view of breast cancers arising from two main cell types of origin. Notwithstanding the potential added value of more detailed categorizations for personalized breast cancer treatment, we suggest that the development of better criteria to identify the two proposed etiologic classes would advance breast cancer research and prevention.

Abstract
BACKGROUND Calcifying cyst odontogenic tumour (CCOT) is a rare benign cystic neoplasm of odontogenic origin. MMPs are responsible for extracellular matrix remodelling and, together their inhibitors and inducer, determinate the level of its turnover in pathological processes, leading to an auspicious microenvironment for tumour development. Thus, our goal was to evaluate matrix metalloproteinases (MMPs-2, -7, -9 and -14), their inhibitors (TIMPs-2, -3, -4 and RECK) and its inductor (EMMPRIN) expression in CCOT. MATERIALS AND METHODS We used 18 cases of CCOT submitted to immunolocalization of the target proteins and analysed in both neoplastic odontogenic epithelial and stromal compartments. RESULTS All molecules evaluated were expressed in both compartments in CCOT. In epithelial layer, immunostaining for MMPs, TIMPs, RECK and EMMPRIN was found in basal, suprabasal spindle and stellate cells surrounding ghost cells and ghost cells themselves, except for MMP-9 and TIMP-2 which were only expressed by ghost cells. In stromal compartment, extracellular matrix, mesenchymal (MC) and endothelial cells (EC) were positive for MMP-2, -7, TIMP-3 and -4, while MMP-9, TIMP-2 and RECK were positive only in MC and MMP-14 only in EC. Statistical significance difference was found between both compartments for MMP-9 (P < 0.001), RECK (P = 0.004) and EMMPRIN (P < 0.001), being more expressed in epithelium than in stroma. Positive correlation between both stromal EMMPRIN and RECK expression was found (R = 0.661, P = 0.003). CONCLUSIONS We concluded that these proteins/enzymes are differentially expressed in both epithelium and stroma of CCOT, suggesting an imbalance between MMPs and their inducer/inhibitors may contribute on the tumour behaviour.
