Abstract
OBJECTIVES IL17 is a critical pro-inflammatory cytokine that is involved in inflammation, multidrug resistance and growth persistence pathways in cancer. This study is aiming at studying the expression of IL17 and hormonal receptors expression in benign and malignant breast lesions using immunohistochemical staining methods. RESULTS A total of 137 cases of breast lesions were studied, 97 (70.8%) were malignant and 40 (29.2%) were benign cases. Age range for malignant and benign cases were between 26 and 80 years [mean age 50 ± 2 years], and 20 to 70 years [mean age 41 ± 4 years], respectively, Odds ratio = 2.3 [1.78-1.99, 95% CI]. The majority of the histopathological diagnosis of the benign and malignant lesions were 21 (15.3%) fibro-adenomas and 87 (63.5%) invasive ductal carcinoma, respectively. Expression of IL17 and age were insignificantly negatively correlated for both groups; benign cases [r = - 0.054, P value 0.742] and malignant cases [r = - 0.080, P value 0.444]. IL17 expression was showing insignificant association with age group, P value 0.065. IL17 expression showed a statistical significance based on the different histopathological diagnosis, P value 0.035. Expression levels of estrogen, progesterone, and human epidermal receptors were showing insignificant difference among IL17 expression categories, P values 0.678, 0.623, and 0.361, respectively.

Abstract
AIMS Fibroadenomas (FAs) and phyllodes tumours (PTs) are fibroepithelial tumours. Mutations in MED12 exon 2 have been reported in FAs. This study investigated the MED12 mutations in a spectrum of fibroepithelial tumours. METHODS AND RESULTS Using direct sequencing, we analysed MED12 exon 2 mutations on 121 samples, including PTs and FAs and variants. We found MED12 mutations in 71.4% of PTs. No significant difference in the mutation frequency was observed between benign, borderline and malignant PTs, and a general lack of correlation existed between mutations and pathological factors associated with PT grading. The mutation patterns were similar between PTs and FAs, with codon 44 being involved most frequently. MED12 mutations were identified in 47.1, 52.6 and 50.0% of complex FAs, juvenile FAs and tubular adenomas (TAs), respectively, and the frequency and mutation patterns were similar between these FA variants and usual FAs. CONCLUSIONS The high frequency and similar patterns of MED12 mutations in FAs and various grades of PTs implies that the MED12 mutation is a common and early pathological event in these fibroepithelial tumours. The similar frequency and patterns of the MED12 mutation between FAs and variants suggests that FA variants are bona fide FAs, with identical pathogenesis involving MED12 mutations.

Reassessment of endothelin receptor A expression in normal and neoplastic human tissues using the novel rabbit monoclonal antibody UMB-8. Peptides 2015; 66:19-25.

Abstract
The endothelins ET-1, ET-2 and ET-3 are a family of peptides, which exert their actions via two G protein-coupled receptor subtypes, ETA and ETB. ET-1 is a potent vasoconstrictor and is involved in the development of different cardiovascular and renal disorders. Additionally, ET-1 and the ETA receptor have been shown to be important mediators of cancer growth and metastasis. We have extensively characterized the novel monoclonal rabbit anti-ETA antibody UMB-8 using transfected cells as well as mouse, rat and human tissues. UMB-8 was then tested in a large series of formalin-fixed and paraffin-embedded human normal and neoplastic tissue specimens. Specificity of UMB-8 was demonstrated by detection of a broad band migrating at 70-80kDa in Western blot analyses of ETA-transfected HEK-293 cells and of different mouse tissues and by agonist-dependent translocation of the immunosignal from the surface of ETA-transfected cells into the cytosol. In tissue samples, UMB-8 yielded an efficient immunostaining of distinct cell populations with a predominance of plasma membrane staining, which was abolished after preadsorption of the antibody with its immunizing peptide. In normal tissue, ETA was present in the heart, blood vessels, gut and kidneys. ETA was also detected with a hitherto unappreciated high prevalence in all types of sarcomas and in glioblastomas, but also in various epithelial tumor entities and in tumor stroma. All in all, UMB-8 may prove of great value in the identification of ETA-expressing tumors during routine histopathological examinations.

Abstract
The local recurrence rate of phyllodes tumors of the breast varies widely among different subtypes, and distant metastasis is associated with poor survival. This study aimed to identify factors that are predictive of local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), and overall survival (OS) in patients with phyllodes tumors of the breast. Clinical data of all patients with a phyllodes tumor of the breast (n = 192) treated at Sun Yat-sen University Cancer Center between March 1997 and December 2012 were reviewed. The Pearson χ2 test was used to investigate the relationship between clinical features of patients and histotypes of tumors. Univariate and multivariate Cox regression analyses were performed to identify factors that are predictive of LRFS, DMFS, and OS. In total, 31 (16.1%) patients developed local recurrence, and 12 (6.3%) developed distant metastasis. For the patients who developed local recurrence, the median age at the diagnosis of primary tumor was 33 years (range, 17-56 years), and the median size of primary tumor was 6.0 cm (range, 0.8-18 cm). For patients who developed distant metastasis, the median age at the diagnosis of primary tumor was 46 years (range, 24-68 years), and the median size of primary tumor was 5.0 cm (range, 0.8-18 cm). In univariate analysis, age, size, hemorrhage, and margin status were found to be predictive factors for LRFS (P = 0.009, 0.024, 0.004, and 0.001, respectively), whereas histotype, epithelial hyperplasia, margin status, and local recurrence were predictors of DMFS (P = 0.001, 0.007, 0.007, and < 0.001, respectively). In multivariate analysis, independent prognostic factors for LRFS included age [hazard ratio (HR) = 3.045, P = 0.005], tumor size (HR = 2.668, P = 0.013), histotype (HR = 1.715, P = 0.017), and margin status (HR = 4.530, P< 0.001). Histotype (DMFS: HR = 4.409, P = 0.002; OS: HR = 4.194, P = 0.003) and margin status (DMFS: HR = 2.581, P = 0.013; OS: HR = 2.507, P = 0.020) were independent predictors of both DMFS and OS. In this cohort, younger age, a larger tumor size, a higher tumor grade, and positive margins were associated with lower rates of LRFS. Histotype and margin status were found to be independent predictors of DMFS and OS.

Abstract
Endothelins are important mediators of physiological and pathophysiologic processes including cardiovascular disorders, pulmonary disease, renal diseases and many others. Additionally, endothelins are involved in many other important processes such as development, cancer biology, wound healing, and even neurotransmission. Here, we review the cell and molecular biology as well as the prominent pathophysiological aspects of the endothelin system.
