BACKGROUND: Chromogranin A (CgA) levels have previously been found to predict mortality in heart failure (HF), but currently no information is available regarding CgA processing in HF and whether the CgA fragment catestatin (CST) may directly influence cardiomyocyte function. METHODS AND RESULTS: CgA processing was characterized in postinfarction HF mice and in patients with acute HF, and the functional role of CST was explored in experimental models. Myocardial biopsies from HF, but not sham-operated mice, demonstrated high molecular weight CgA bands...

OBJECTIVES: To investigate possible relationships among oral mucosal epithelial MUC1 expression, salivary female gonadal hormones and stress markers, and clinical characteristics in patients with burning mouth syndrome (BMS). DESIGN: Thirty post-menopausal female patients with BMS (60.0±5.0 years) were included. Clinical and psychological evaluations were performed and the expression level of oral mucosal epithelial MUC1 was analyzed. The levels of cortisol, dehydroepiandrosterone (DHEA), 17β-estradiol, progesterone, chromogranin A, and blood contamination were determined from unstimulated whole saliva (UWS) and stimulated whole saliva (SWS) samples...

Neuroendocrine tumors (NETs) comprise a heterogeneous group of malignancies that express neuropeptides as synaptophysin, chromogranin A (CgA), and specific neuronal enolase (NSE), among others. Vasopressin (AVP) is a neuropeptide with an endocrine, paracrine, and autocrine effect in normal and pathological tissues. AVP receptors are present in human lung, breast, pancreatic, colorectal, and gastrointestinal tumors. While AVP V1 receptors are associated with stimulation of cellular proliferation, AVP V2 receptor (V2r) is related to antiproliferative effects...

A 17-year-old female wolf (Canis lupus lupus) had a right lung mass that was adhered to the thoracic cavity. Histopathological examination revealed that the mass consisted of sheets, cord or ribbon-like structures of monotonous, small, cuboidal cells with round, oval or short-spindle nuclei and scant clear cytoplasm, demarcated by a fine fibrovascular stroma. Focal necrosis, congestion and thrombi were observed. Immunohistochemically, the tumor cells diffusely expressed cytokeratin AE1/AE3, and some expressed chromogranin A, neural cell adhesion molecule (CD56) and thyroid transcription factor-1...

BACKGROUND: Chromogranin A (CgA), a circulating protein released by the neuroendocrine system, can regulate vascular physiology and angiogenesis. Full-length CgA (CgA1-439) and its fragment CgA1-76 (called vasostatin-1, VS-1) preserve the physiological integrity of the endothelial barrier function and are antiangiogenic, whereas CgA1-373 is proangiogenic. We investigated whether these polypeptides are altered in patients with various degrees of carotid artery atherosclerosis. METHODS: We studied 81 patients with carotid artery atherosclerosis, asymptomatic for cerebrovascular diseases...

Introduction Both physiologic stress and chronic heart disease are associated with increased systemic levels of chromogranin A (CGA) and NT-proBNP. Marathon running causes physiological stress and imposes a significant cardiac burden. Polyphenol-rich Mediterranean and Asian diets have been demonstrated to exert beneficial effects on the cardiovascular system. In this study we investigated whether pretreatment with a polyphenol beverage could attenuate the physiological and cardiac stress associated with a marathon...

Acanthomatous ameloblastoma is a common, locally invasive, nonmetastasizing tumor of the canine oral cavity. The long-term prognosis for canine acanthomatous ameloblastoma is good if complete excision can be achieved, usually by maxillectomy or mandibulectomy. A variant of acanthomatous ameloblastoma with atypical foci was noted in 5 dogs. There was no age, breed, or sex predisposition. Atypical cells were pleomorphic with a high mitotic rate. They were immunohistochemically negative for cytokeratin, vimentin, melan A, PNL2, CD3, Pax5, CD18, chromogranin A, and synaptophysin...

Endolymphatic sac tumors (ELSTs) are rare neoplasms of the inner and middle ear described in humans. Diagnosis of such neoplasms is difficult and largely dependent on a combination of histologic, immunohistochemical, and clinical findings. Although the neoplastic cells lack cellular features of malignancy, these are clinically aggressive tumors that often invade the surrounding temporal bone. Here, we describe 2 dogs with middle ear masses that share morphologic, immunohistochemical, and clinical similarities with human ELSTs...

Carcinoid tumor of the prostate is extremely rare. Here we report a unique case of prostate cancer that underwent complete transformation from conventional adenocarcinoma to carcinoid-like tumor shortly after androgen deprivation treatment (ADT). The patient was a 59years old man who presented with lower urinary tract symptoms. His biopsy specimen demonstrated a high-grade prostatic adenocarcinoma with mixed acinar and ductal features. After ADT for 6months, the patient underwent radical prostatectomy. The post-ADT tumor showed monotonous neoplastic cells with fine granular chromatin forming rosette-like structures, resembling a carcinoid tumor...

A 37-year-old man visited a previous hospital because of left abdominal pain. A contrast-enhanced CT scan revealed a 7 cm solid tumor in the pancreas body, and the patient was referred to our hospital. EUS-FNA showed that the tumor cells were positive for b-catenin in the nuclei, as well as for CD10 and CD56. On the other hand, the cells were negative for chromogranin A and synaptophysin. This is the typical immunohistochemical pattern of a solid pseudopapillary neoplasm(SPN). Therefore, we diagnosed this case as SPN before surgery...

A 42-year-old woman was admitted to our hospital because of a positive fecal occult blood test. Colonoscopy examination revealed an elevated lesion measuring 25mm in diameter at the terminal ileum. A histological diagnosis of neuroendocrine tumor(NET)was made based on biopsy specimens taken from the lesion. Since no apparent distant metastasis other than the ileocolic lymph nodes was noted, laparoscopy-assisted ileocecal resection with regional lymph node dissection was performed. In the resected material, NET(G2)limited to the subserosa layer was present...

High homocysteine (Hcy) concentration in serum has been associated to stress and inflammation in humans, but this association has not been studied in saliva in any animal species. The purpose of this research was to study salivary Hcy levels in pigs under stressful and inflammatory conditions. A commercially available enzyme-linked immunosorbent assay specific for Hcy determination in pigs was adapted and validated in saliva, yielding reproducible and accurate results. Hcy was measured in paired serum-saliva samples and no correlation was observed between serum and salivary Hcy...
