Xp11 translocation renal cell carcinoma (RCC) is a specific type of renal cell carcinoma recently placed under the "MiT family translocation RCC" at the last 2013 ISUP Vancouver classification of renal neoplasia. This tumor contains variable proportions of clear cells and could easily mimic papillary RCC, clear cell type, and clear cell papillary RCC. Given the small number of published cytologic findings of this tumor, it could easily present as a diagnostic pitfall. We describe a case of a 23-year-old man with a history of prior nephrectomy who presented with multiple mediastinal lymphadenopathies on imaging surveillance follow-up...

Adipokines are bioactive proteins that mediate proliferation, metabolism, inflammation, and angiogenesis. Adiponectin is an important adipokine that exerts multiple key functions via its anti-metabolic syndrome and anti-inflammatory properties. A number of adiponectin receptors, AdipoR1, AdipoR2 and T-cadherin, have been identified. Recent studies have suggested the involvement of adiponectin and receptors in several cancers, including prostate, breast, endometrial, brain, and colon cancer. Altered levels of adiponectin expression, or its interacting receptors, in cancers can lead to dysregulation of signaling pathways...

First-generation somatostatin receptors ligands (SRL) are the mainstay in the medical treatment of acromegaly, however the percentage of patients controlled with these drugs significantly varies in the different studies. Many factors are involved in the resistance to SRL. In this review, we update the physiology of somatostatin and its receptors (sst), the use of SRL in the treatment of acromegaly and the factors involved in the response to these drugs. The SRL act through interaction with the sst, which up to now have been characterized as five subtypes...

A 90-year-old woman was referred to our hospital because of abdominal distension and pretibial edema. No tumors were palpable in either breast. Her abdomen was distended and palpitation was noticed. Laboratory examination revealed hypercalcemia and elevated levels of tumor markers(PIVKA- II , CEA, CA19-9, SCC). Contrast-enhanced computed tomography(CT) showed pleural effusion and ascites, an approximately 17-mm high-contrast mass in the D area of the left breast, and osteolysis of the dorsal lumber spine. We initiated treatment for pleural effusion, ascites, and hypercalcemia...

The disruption of endothelial integrity and the occurrence of angiogenesis in response to advanced glycation end products (AGEs) contribute greatly to micro- and macrovascular complications associated with diabetes mellitus (DM). Among human dermal, brain and retinal vascular endothelial cells, activation of ERM protein (Ezrin, radixin and moesin protein), moesin, by phosphorylation of Threonine 558 (Thr-558) is involved in AGE-induced hyperpermeability and angiogenesis via the Rho and Rho-associated protein kinase (Rho/ROCK) and p38 pathways...

REVIEW

Cadherin-11 has been identified as a key regulator of synovial architecture mediating contact between Fibroblast-like Synoviocytes and organization in the lining layer. A central role for cadherin-11 has also been suggested in the formation of the rheumatoid pannus. Therapeutic targeting of cadherin-11 results in amelioration of autoimmune experimental arthritis, as well as of experimental fibrosis. In addition, cadherin-11 expression is upregulated in the synovium of patients with chronic inflammatory arthritis, whereas detection of cadherin-11 mRNA transcripts in the peripheral blood has been associated with more severe disease phenotypes in two prototypic conditions of chronic joint inflammation and fibrosis, namely, rheumatoid arthritis and systemic sclerosis, respectively...

Gastrointestinal metastases from breast cancer are not common. We present a 58-year-old female diagnosed with lobular breast cancer some years before whose relapses were gastric and colonic mucosal. Simultaneous metastases are extremely rare. To our knowledge, no cases of initial dual affectation have been reported. The patient also showed gastritis by Helicobacter pylori. Invasive lobular breast carcinoma is the most frequent special type of breast cancer and carries some specific molecular alterations such as loss of expression of E-cadherin...

The cadherin-catenin adhesion complex is the key component of the intercellular adherens junction (AJ) that contributes both to tissue stability and dynamic cell movements in epithelial and nonepithelial tissues. The cadherin adhesion complex bridges neighboring cells and the actin-myosin cytoskeleton, and thereby contributes to mechanical coupling between cells which drives many morphogenetic events and tissue repair. Mechanotransduction at cadherin adhesions enables cells to sense, signal, and respond to physical changes in their environment...

Collective cell migration critically depends on cell-cell interactions coupled to a dynamic actin cytoskeleton. Important cell-cell adhesion receptor systems implicated in controlling collective movements include cadherins, immunoglobulin superfamily members (L1CAM, NCAM, ALCAM), Ephrin/Eph receptors, Slit/Robo, connexins and integrins, and an adaptive array of intracellular adapter and signaling proteins. Depending on molecular composition and signaling context, cell-cell junctions adapt their shape and stability, and this gradual junction plasticity enables different types of collective cell movements such as epithelial sheet and cluster migration, branching morphogenesis and sprouting, collective network migration, as well as coordinated individual-cell migration and streaming...

Ovarian cancer accounts for only 3% of all cancers in women but is the most lethal gynaecologic malignancy. Low-grade and high-grade ovarian serous carcinomas (OSCs) represent two different diseases with different prognosis, approaches to detection and treatment. We assessed correlation between, MAPK, topoIIα, E-cadherin immunoexpression and clinicopathological features with overall survival (OS) in OSCs. The study included 81 patients undergoing surgery between January 1995 and December 2005.Formalin fixed paraffin embedded tumour sections were reviewed and examined immunohistochemically using antibodies against MAPK, topoIIα and E-cadherin...

Endocrine disrupting chemicals (EDCs) are natural or synthetic compounds that interfere with normal functions of natural hormones in the body, leading to a disruption of the endocrine system. Specifically, EDCs have the potential to cause formation of several hormone-dependent cancers, including breast, ovarian, and prostate cancers. Epithelial mesenchymal transition (EMT) process by which epithelial cells lose their cell polarity and cell-cell adhesion and acquire mesenchymal phenotype is closely associated with malignant transformation and the initiation of cancer metastasis...

The hallmarks of cancer are characterized by functional capabilities that allow cancer cells to survive, proliferate and disseminate during the multistep tumorigenesis. Cancer being a cellular disease, changes in cellular glycoproteins play an important role in malignant transformation and cancer progression. The present review summarizes various studies that depicted correlation of glycosylation with tumor initiation, progression and metastasis, which are helpful in early diagnosis, disease monitoring and prognosis...

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a heterogeneous syndrome which is usually characterized by urinary frequency, nocturia, and bladder pain. Several pathomechanisms have been proposed, including uroepithelial dysfunction, mast cell activation, neurogenic inflammation, autoimmunity, and occult urinary tract infections. It is possible that an inflammatory process alters regulation of urothelial homeostasis and results in dysfunction of the bladder epithelium. Different phenotypes of IC/BPS have been explored including Hunner and non-Hunner type IC, hypersensitive bladder, and bladder pain both with and without functional somatic syndrome...

Autism spectrum disorder (ASD) comprises a range of neurological conditions that affect individuals' ability to communicate and interact with others. People with ASD often exhibit marked qualitative difficulties in social interaction, communication, and behavior. Alterations in neurite arborization and dendritic spine morphology, including size, shape, and number, are hallmarks of almost all neurological conditions, including ASD. As experimental evidence emerges in recent years, it becomes clear that although there is broad heterogeneity of identified autism risk genes, many of them converge into similar cellular pathways, including those regulating neurite outgrowth, synapse formation and spine stability, and synaptic plasticity...

REVIEW
Iva Petrovchich, James M Ford
Gastric cancer ranks as the third leading cause of cancer mortality worldwide and confers a 5-year survival of 20%. While most gastric cancers are sporadic, ~1%-3% can be attributed to inherited cancer predisposition syndromes. Germline E-cadherin/CDH1 mutations have been identified in families with an autosomal dominant inherited predisposition to diffuse gastric cancer. The cumulative risk of gastric cancer for CDH1 mutation carriers by age 80 years is reportedly 70% for men and 56% for women. Female mutation carriers also have an estimated 42% risk for developing lobular breast cancer by age 80 years...

Breast cancer, with a lifelong risk of one in nine, is the most common cancer among women. In Iran, breast cancer is one of the growing and important women's health problems. Several environmental, genetic and epigenetics factors have been suggested to have a role in breast cancer development. Epigenetics alterations are heritable changes in gene expression that occur without causing any change in DNA sequence. DNA methylation as a main epigenetics modification in human cancer is found as a promising biomarker in early detection of breast cancer...

Much research effort has been devoted to identifying prognostic factors for esophageal squamous cell carcinoma (ESCC) by immunohistochemistry; however, no conclusive findings have been reached thus far. We hypothesized that certain molecules identified in previous studies might serve as useful prognostic markers for ESCC. Therefore, the aim of the current study was to validate the most relevant markers showing potential for ESCC prognosis in our prospective esophageal cancer database. A literature search was performed using the PubMed database for papers published between 1980 and 2015 using the following key words: 'esophageal cancer,' 'prognosis,' and 'immunohistochemistry...

Epithelial cadherin (encoded by the CDH1 gene) is a tumor suppressor glycoprotein that plays a role in the invasion and metastasis of human cancers. As previous studies regarding the association between CDH1 promoter methylation and head and neck squamous cell carcinoma (HNSCC) have yielded inconsistent conclusions, a meta-analysis was performed. A systematic literature review was undertaken from four databases: PubMed, Embase, Google Scholar, and Web of Science. Finally, a total of 23 studies (including 1,727 cases of HNSCC and 555 normal controls) were included in the present study...
