Epidemiological studies have associated the exposure to permethrin and malathion with increased risk of leukemia and lymphoma. The aim of this study was to evaluate whether in vitro exposure to permethrin and malathion induces aberrations in genes involved in the etiology of these hematological malignancies. Genetic abnormalities in the IGH, KMT2A (MLL), ETV6 and RUNX1 genes; and aneuploidy induced by the in vitro exposure to permethrin and malathion (200μM, 24h), were analyzed by FISH in peripheral blood mononuclear cells (PBMCs)...

In this study, we investigated the effects of dietary myo-inositol on the growth and intestinal physical barrier functions of young grass carp (Ctenopharyngodon idella). A total of 540 young grass carp (221.83 ± 0.84 g) were fed six diets containing graded levels of myo-inositol (27.0, 137.9, 286.8, 438.6, 587.7 and 737.3 mg/kg) for 10 weeks. After the growth trial, fish were challenged with Aeromonas hydrophila for 14 days. The results indicated that compared with optimal myo-inositol levels, myo-inositol deficiency (27...

BACKGROUND: Disease-defining chromosomal translocations are seen in various neoplasms, especially in lymphomas and leukemias. Translocation detection at the DNA level is often complicated by chromosomal breakpoints that are distributed over very large regions. We have developed a ligation-based assay [the looped ligation assay (LOLA)] to detect translocations from diseases with multiple widely spaced breakpoint hot spots. METHODS: Oligonucleotide sets that probe breakpoints of IGH-BCL2 (immunoglobulin heavy-apoptosis regulator) in follicular lymphoma (FL), MYC-IGH (MYC proto-oncogene, bHLH transcription factor- immunoglobulin heavy) in Burkitt lymphoma (BL) and BCR-ABL1 (RhoGEF and GTPase activating protein-ABL proto-oncogene 1, non-receptor tyrosine kinase) in chronic myelogenous leukemia (CML) were designed...

Posttransplant lymphoproliferative disorders (PTLDs) are a diverse group of lymphoid or plasmacytic proliferations frequently driven by Epstein-Barr virus (EBV). EBV-negative PTLDs appear to represent a distinct entity. This report describes an unusual case of a 33-year-old woman that developed a monomorphic EBV-negative PTLD consistent with diffuse large B-cell lymphoma (DLBCL) 13 years after heart-lung transplant. Histological examination revealed marked pleomorphism of the malignant cells including nodular areas reminiscent of classical Hodgkin lymphoma (cHL) with abundant large, bizarre Hodgkin-like cells...

Quercetin is a natural product that is sold as a supplement in health food stores. While there are reported benefits for this flavonoid as a dietary supplement due to antioxidant properties, the full scope of its biological interactions has not been fully addressed. To learn more about the mechanisms of action related to quercetin, we exposed zebrafish (Danio rerio) embryos to 1 and 10μg/L quercetin for 96h starting at 3h post fertilization. Quercetin up to 10μg/L did not induce significant mortality in developing fish, but did increase prevalence of an upward-curved dorsal plane in hatched larvae...

Background: Recently double-hit lymphoma or double protein expressor lymphoma has been identified as a distinct group of diffuse large B cell lymphoma with poor prognosis. However, the expression status, clinical and prognostic effect of combined overexpression of MYC and BCL2 in extranodal NK/T-cell lymphoma, nasal type (ENKTL) are not known. Materials and methods: Paraffin-embedded lymphoma samples from 53 patients with newly diagnosed ENKTL were studied using immunohistochemistry for MYC and BCL2, and fluorescent in situ hybridization (FISH) for MYC and BCL2 were done on 5 tissue sections with highest percentages of both MYC and BCL2 positive lymphoma cells...

REVIEW
Pierre Sesques, Nathalie A Johnson
High-grade B-cell lymphomas (HGBLs) with MYC and BCL2 and/or BCL6 rearrangements, so-called "double-hit" lymphomas (HGBL-DH), are aggressive lymphomas that form a separate provisional entity in the 2016 revised World Health Organization Classification of Lymphoid Tumors. Fluorescence in situ hybridization (FISH) will be required to identify HGBL-DH and will reclassify a subset of diffuse large B-cell lymphomas (DLBCLs) and HGBLs with features intermediate between DLBCL and Burkitt lymphoma into this new category...

Double-hit lymphomas are rare tumors that are defined by a chromosomal breakpoint affecting the MYC/8q24 locus in combination with another recurrent breakpoint, mainly a t(14; 18)(q32;q21)involving BCL2. We report a case of a 38-yearold woman with a 2-month history of abdominaldistention. 18F-FDG PET showed multiple positive systemic lymph nodes, positive peritoneum, and multiple positive intra-abdominal masses. Histopathology results of the cervical lymph node were compatible with double-hit follicular lymphoma(Grade 3A)because fluorescence in situ hybridization(FISH)demonstrated both MYC rearrangement and BCL2 gene fusion...

IRF4/MUM1-positive lymphoma is a new subgroup of germinal center-derived B-cell lymphoma, predominantly involving the Waldeyer ring (WR) in children. CD5 expression is rare in these lymphomas. We report a 7-year-old Chinese male with B-cell lymphoma. Evaluation of his specimen by morphology, immunohistochemistry, and FISH analysis demonstrated IRF4/MUM1-positive lymphoma with strong and extensive CD5 and CD10 positivity. Despite the lack of t(14;18)(q32;q21) rearrangement, BCL2 protein was expressed. Our report highlights the clinicopathologic features of IFR4/MUM1-positive lymphoma in WR with co-expression of CD5 and CD10, and thereby provides insight into this newly recognized disease entity...

Bisphenol A (BPA) is an endocrine disruptor, and could induce germ cells apoptosis in the testis of mammals. But whether it could affect fish in the same mechanism has not' been studied till now. In the present study, to investigate the influence of BPA on testis germ cells in fish, adult male rare minnow Gobiocypris rarus were exposed to 225μgL(-1) (0.99μM) BPA for 1, 3 and 9 weeks. Through TdT-mediated dUTP nick end labeling (TUNEL) and transmission electron microscope (TEM) analysis, we found that the amount of apoptotic spermatocytes significantly increased in a time dependent manner following BPA exposure...

The diagnostics of leukemia relies upon multi-parametric approach involving a number of different pathology disciplines such as flow cytometry, histopathology, cytogenetics and molecular genetics [fluorescent in situ hybridization (FISH) and polymerase chain reaction (PCR)]. Childhood leukemia is often determined by the presence of specific chromosomal translocation that entails the generation of preleukemic fusion genes (PFG). In the last two decades, several studies have reported observations that PFG are present in healthy population and not necessarily result in leukemia...

BACKGROUND AND AIMS: Primary gastric B-cell lymphoma is the second most common malignancy of the stomach. There are many controversial issues about its diagnosis, treatment and clinical management. "Double-hit" and "double-protein" involving gene rearrangement and protein expression of c-Myc and bcl2/bcl6 are the most used terms to describe DLBCL poor prognostic factors in recent years. However, very little is known about the role of these prognostic factors in primary gastric B-cell lymphomas...

Lipoteichoic acid (LTA) is a major constituent of the cell wall of Gram-positive bacteria. The structure and immunomodulation of LTA vary greatly between different species. LTA from Lactobacillus plantarum has been shown to exert anti-pathogenic effects. Vibrio anguillarum is a major causative agent of vibriosis, one of the most prevalent fish diseases. The purpose of this study was to examine the effects of L. plantarum LTA on V. anguillarum growth, adhesion, and induced inflammation and apoptosis in intestinal epithelial cells of silvery pomfret (Pampus argenteus)...

The authors present a retrospective analysis of follicular lymphomas (FL) and mantle cell lymphomas (MCL) diagnosed according to the WHO classification (2008) in consecutive biopsies of GI organs in a period of 11 years. The series includes 18 patients with FL verified in 22 biopsies and 44 patients with MCL diagnosed in 54 biopsies. FL represented always a solitary tumor, most often - up to ¾ of all the cases - of a small intestine, more often in its jejunoileal than duodenal parts. The biopsies were obtained almost equally by endoscopical approach, they were usually mucosal and rarely polypectomic, as well as by surgical resections (54,5 % and 45,5 % of the cases respectively)...
