Aquaporin-3 (AQP3), a water and glycerol channel, plays an important role in epidermal function, with studies demonstrating its involvement in keratinocyte proliferation, differentiation and migration and epidermal wound healing and barrier repair. Increasing speculation about the use of histone deacetylase (HDAC) inhibitors to treat skin diseases led us to investigate HDAC's role in the regulation of AQP3. The broad-spectrum HDAC inhibitor, suberolyanilide hydroxamic acid (SAHA) induced AQP3 mRNA and protein expression in a dose- and time-dependent manner in normal keratinocytes...

Dextran-capped gold nanoparticles (Au-dextran NPs) were prepared exploiting the natural polysaccharide polymer as both reducing and stabilizing agent in the synthesis process, aiming at studying their antitumor effect on solid carcinoma and EAC-bearing mice. To this end, Au-dextran NPs were designed via simple eco-friendly chemical reaction and they were characterized revealing the monodispersed particles with narrow distributed size of around 49nm with high negative charge. In vivo experiments were performed on mice...

F-FDG PET/CT is now an established modality for staging and restaging high-grade lymphomas, including diffuse large B-cell lymphoma. We here present the case of a 51-year-old woman successfully treated for diffuse large B-cell lymphoma. Follow-up F-FDG PET/CT demonstrated an unusual site of relapse involving left Stensen (parotid) duct, which was confirmed with cytology. By identifying such unusual sites of lymphomatous involvement, F-FDG PET/CT can have significant bearing on patient management.

BACKGROUND: Bronchial-associated lymphoid tissue (BALT) lymphoma is a relatively rare form of B-cell non-Hodgkin lymphoma (B-NHL). To date, the standard systemic treatment for this disease is still under debate, and few data are accessible for newly diagnosed unresectable BALT lymphoma presented with advanced disease. The combination of rituximab (R) and cladribine (2-CdA) has shown some activity in indolent B-NHL, but its usage has not been tested in disseminated BALT lymphoma so far...

Overexpression of the BCL2 is associated with a poor prognosis in diffuse large B-cell lymphoma (DLBCL). The assessment of MYC immunohistochemistry (IHC) is becoming optimized, whereas the criteria for BCL2 positivity are highly variable. Furthermore, data on the frequency and prognostic value of BCL2 positivity are conflicting. We aimed to evaluate BCL2 expression by IHC and assess the prognostic significance of the histopathologically-scored BCL2 expression in 456 patients with DLBCL uniformly treated with standard immunochemotherapy (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone; R-CHOP)...

CD30 is a member of the tumor necrosis factor receptor superfamily, member 8 (TNFRSF8), and its normal expression is restricted to activated T and B cells. In tumor cells, CD30 expression is most commonly associated with lymphoid malignancies (Hodgkin and non-Hodgkin lymphomas) and is a therapeutic target using anti-CD30 antibody. CD30 expression has been reported also in mostly adult non-lymphoid malignancies, raising the possibility of CD30-targeted therapy for additional tumors. In this study, we examined the incidence of CD30 expression in 251 hematopoietic and 334 non-hematopoietic cases of pediatric tumors...

Deregulation of MYC oncoprotein in cancers can result from multiple oncogenic mechanisms. Although MYC translocations define Burkitt lymphoma and MYC protein expression is a poor prognostic factor in undifferentiated neuroblastomas, the distribution of MYC protein (c-MYC) across other pediatric small round blue cell tumors (SRBCT) has not been well characterized. We undertook this study to assess MYC protein expression in a large cohort of pediatric lymphomas, sarcomas, and other SRBCT. Tissue microarrays containing 302 SRBCT were successfully evaluated by immunohistochemistry using anti-MYC clone Y69, with nuclear positivity scored as 0%, 1%-25%, 26%-50%, 51%-75%, or 76%-100%...

Background: B-cell survival is regulated through interactions of B-cell-activating factor (BAFF) and a proliferation-inducing ligand (APRIL) with their receptors transmembrane activator and CAML interactor (TACI) and B-cell maturation antigen (BCMA). We evaluated the diagnostic potential of soluble TACI (sTACI) and soluble BCMA (sBCMA) in cerebrospinal fluid (CSF) and serum as biomarkers in primary CNS lymphoma (PCNSL). Methods: CSF (n=176) and serum samples (n=105) from patients with clinically or radiologically suspected PCNSL as well as from control patients were collected prospectively...

The addition of anti-CD20 monoclonal antibodies to the treatment of B-cell malignancies has dramatically affected the field as well as the lives of patients. Rituximab in particular has been combined safely with conventional chemotherapy and has resulted in improved overall survival in major histologic subtypes of B-cell lymphoma and chronic lymphocytic leukemia. It is incorporated into the standard initial treatment of nearly all of these diseases. Novel anti-CD20 antibodies are currently under development...

Mitochondria are important regulators of cell death and cell survival. Mitochondrial Ca(2+) levels are critically involved in both of these processes. On the one hand, excessive mitochondrial Ca(2+) leads to Ca(2+)-induced mitochondrial outer membrane permeabilization and thus apoptosis. On the other hand, mitochondria need Ca(2+) in order to efficiently fuel the tricarboxylic acid cycle and maintain adequate mitochondrial bioenergetics. For obtaining this Ca(2+), the mitochondria are largely dependent on close contact sites with the endoplasmic reticulum (ER), the so-called mitochondria-associated ER membranes...

The hepatitis B virus (HBV) is a major global issue, because an increased risk of hepatocellular carcinoma among patients infected with HBV is well established. Recently, it has been suggested that HBV is associated with other human cancers. However, the association between HBV and the risk of onset of hematological malignancies remains controversial. The aim of this large-scale retrospective cohort study was to evaluate the association between HBV infection and hematological malignancies. A retrospective analysis of 86,115 newly admitted patients at Shanghai Ruijin Hospital was performed...

Epstein-Barr virus (EBV) replication contributes to multiple human diseases, including infectious mononucleosis, nasopharyngeal carcinoma, B cell lymphomas, and oral hairy leukoplakia. We performed systematic quantitative analyses of temporal changes in host and EBV proteins during lytic replication to gain insights into virus-host interactions, using conditional Burkitt lymphoma models of type I and II EBV infection. We quantified profiles of >8,000 cellular and 69 EBV proteins, including >500 plasma membrane proteins, providing temporal views of the lytic B cell proteome and EBV virome...

The role of the tumor microenvironment in leukemias and lymphomas is well established, yet the intricacies of how the malignant cells regulate and influence their non-malignant counterparts remain elusive. For example, chronic lymphocytic leukemia (CLL) is an expansion of malignant CD5(+)CD19(+) B cells, yet the non-malignant T cells play just as large of a role in disease presentation and etiology. Herein, we review the dynamic tumor cell to lymphoid repertoire interactions found in two non-Hodgkin's lymphoma subtypes: CLL and angioimmunoblastic T-cell lymphoma...

Several infectious agents appear to provide a proliferative signal -- "antigen-drive" - that could be implicated in the pathogenesis of various type of Non-Hodgkin Lymphoma (NHL). A classical model of the infection-driven lymphoproliferative disorder is Helicobacter pylori-induced gastric MALT lymphoma, where antibiotic therapy allows the eradication of both the infectious agent and the clonal B-cell expansion. Following the footsteps of this example, several retrospective studies have found a correlation with other pathogens and B-cell Lymphomas, adding new relevant information about pathogenesis and laying the groundwork for chemotherapy-free treatments...
