BACKGROUND: Most children with cancer live in resource-limited countries where malnutrition is often prevalent. We identified the relationship between malnutrition and treatment-related morbidity (TRM), abandonment of therapy, and survival of children with cancer in Nicaragua to better inform targeted nutritional interventions. PROCEDURE: We conducted a retrospective review of patients aged 6 months to 18 years with newly diagnosed acute lymphoblastic leukemia, acute myeloid leukemia (AML), Wilms tumor, Hodgkin lymphoma, or Burkitt lymphoma (BL) who were treated between January 1, 2004, and December 31, 2007 at Children's Hospital Manuel de Jesus Rivera in Managua, Nicaragua...

Wilms' tumor is the most common childhood renal malignancy. A genome-wide association study identified LIM domain only 1 (LMO1) as having oncogenic potential. We examined the associations between LMO1 gene polymorphisms and susceptibility to Wilms' tumor. In this hospital-based, case-control study, we recruited 145 children with Wilms' tumor and 531 cancer-free children. Four polymorphisms (rs110419 A>G, rs4758051 G>A, rs10840002 A>G and rs204938 A>G) were genotyped using Taqman methodology. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to measure the associations between selected polymorphisms and Wilms' tumor susceptibility...

The Wilms' tumor 1 (WT1) antigen is expressed in solid and hematological malignancies, but not healthy tissues, making it a promising target for cancer immunotherapies. Immunodominant WT1 epitopes, the native HLA-A2/WT1126-134 (RMFPNAPYL) (HLA-A2/RMFPNAPYL epitope (WT1A)) and its modified variant YMFPNAPYL (HLA-A2/YMFPNAPYL epitope (WT1B)), can induce WT1-specific CD8(+) T cells, although WT1B is more stably bound to HLA-A*02:01. Here, to further determine the benefits of those two targets, we assessed the naive precursor frequencies; immunogenicity and cross-reactivity of CD8(+) T cells directed toward these two WT1 epitopes...

Background: Female survivors of childhood cancer treated with abdominal radiotherapy who manage to conceive are at risk of delivering premature and low-birthweight offspring, but little is known about whether abdominal radiotherapy may also be associated with additional complications during pregnancy and labor. We investigated the risk of developing pregnancy and labor complications among female survivors of childhood cancer in the British Childhood Cancer Survivor Study (BCCSS). Methods: Pregnancy and labor complications were identified by linking the BCCSS cohort (n = 17 980) to the Hospital Episode Statistics (HES) for England...

Dipeptidase 1 (DPEP1) is a zinc-dependent metalloproteinase that is fundamental in glutathione and leukotriene metabolism. DPEP1 was initially considered as a tumor suppressor gene in Wilms' tumor and breast cancer. However, it has been reported that DPEP1 is upregulated in colorectal cancers (CRCs) and high DPEP1 expression levels are associated with poorer patient survival. The role of DPEP1 genes in CRC, as well as their expression, requires investigation. Therefore, the present study investigated DPEP1 expression using reverse transcription-quantitative polymerase chain reaction or immunohistochemistry on surgically resected samples from CRC cases, and further examined the biological significance of DPEP1 by comparing the expression of the epithelial to mesenchymal transition (EMT) markers, including epithelial cadherin and Vimentin to clarify the function of DPEP1 in CRC, particularly in metastasis...

Wilms tumor is a pediatric kidney cancer associated with inactivation of the WT1 tumor-suppressor gene in 5-10% of cases. There is an urgent need to illustrate risk factors which can trigger the motility of Wilms tumor cells. Our present study revealed that mono-(2-ethylhexyl) phthalate (MEHP) exposure can significantly increase the in vitro migration and invasion of G401 and WiT49 cells. Real time PCR and western blot analysis revealed that MEHP treatment can increase the expression of metalloproteinase-2 (MMP-2) and MMP-9, while had no effect on the expression of MMP-1, MMP-3, or MMP-12...

Insulin-like growth factor (IGF) binding proteins (IGFBPs) constitute a family of six secreted proteins that regulate the signaling of insulin-like growth factors (IGFs). IGFBP5 is the most conserved family member in vertebrates and the major IGF binding protein in bone. IGFBP5 is required for normal development of the musculoskeletal system, and various types of cancer frequently express high levels of IGFP5. Here we identify the gene encoding IGFBP5 as a novel downstream target of the Wilms tumor protein WT1...

Autophagy is a physiological pathway characterized by lysosome-dependent self-digestion to recycle damaged or superfluous cellular content. Deregulation of autophagy hampers the maintenance of cellular homeostasis and contributes to tumorigenesis. However, during anticancer therapy, autophagy activation contributes to development of resistance. Thus autophagy has been recognized as an important pathway and a therapeutic target in cancer. Nephroblastoma (Wilm's tumor) is a common childhood malignancy, the prognosis of the metastatic and relapsed cases remains poor...

MYCN is a member of the MYC family of proto-oncogenes. It encodes a transcription factor, MYCN, involved in the control of fundamental processes during embryonal development. The MYCN protein is situated downstream of several signaling pathways promoting cell growth, proliferation and metabolism of progenitor cells in different developing organs and tissues. Conversely, deregulated MYCN signaling supports the development of several different tumors, mainly with a childhood onset, including neuroblastoma, medulloblastoma, rhabdomyosarcoma and Wilms' tumor, but it is also associated with some cancers occurring during adulthood such as prostate and lung cancer...

WT1 is a transcription factor which regulates the epithelial-mesenchymal balance during embryonic development and, if mutated, can lead to the formation of Wilms' tumour, the most common paediatric kidney cancer. Its expression has also been reported in several adult tumour types, including breast cancer, and usually correlates with poor outcome. However, published data is inconsistent and the role of WT1 in this malignancy remains unclear. Here we provide a complete study of WT1 expression across different breast cancer subtypes as well as isoform specific expression analysis...

The Wilms' tumor oncogene protein (WT1) is a highly validated tumor antigen for immunotherapy. WT1-targeted immunotherapy has been extensively explored in multiple human trials in various cancers. However, clinical investigations using WT1 epitopes have generally focused on two peptides, HLA-restricted to HLA-A*02:01 or HLA-A*24:02. The goal of this study was to identify new epitopes derived from WT1, to expand the potential use of WT1 as a target of immunotherapy. Using computer-based MHC-binding algorithms and in vitro validation of the T cell responses specific for the identified peptides, we found that a recently identified HLA-A*24:02-binding epitope (239-247), NQMNLGATL (NQM), was also a strong CD8(+) T cell epitope for HLA-A*02:01 molecule...

Wilms' tumor (WT) is a most common renal cancer that occurs among children, and microRNA-19b (miR-19b) usually participates in various human cancers. Importantly, the PTEN/PI3K/Akt signaling pathway plays a key role in cell apoptosis, growth and proliferation. Thus, our present study aims to investigate the effect of miR-19b on the PTEN/PI3K/Akt signaling pathway during WT cell proliferation, migration and apoptosis. WT tissues and adjacent normal tissues from WT patients were collected. qRT-PCR was applied to detect miR-19b expression in both the WT tissues and the adjacent normal tissues, immunohistochemistry was applied to detect the protein expressions of PTEN, P13K and p-Akt, SK-NEP-1 cells were divided into the blank, negative control (NC), miR-19b mimics and miR-19b inhibitors groups...

Wilms' tumor 1 (WT1) is a promising target of new immunotherapies for acute myeloid leukemia (AML) as well as for other cancers. OCV-501 is a helper peptide derived from the WT1 protein. OCV-501 induced OCV-501-specific Type 1 T-helper (Th1) responses dose-dependently and stimulated helper activity of the specific Th1 cells in peripheral blood mononuclear cells from healthy donors. OCV-501 also enhanced the increase in WT1-killer peptide-specific cytotoxic T lymphocytes. OCV-501 stimulated the OCV-501-specific Th1 clones in an HLA class-II restricted manner and formed a complex with HLA class-II protein...

BACKGROUND: Wilms tumor (WT) is the most common urologic cancer in children. However, genetic bases underlying WT remain largely unknown. Previous studies indicated that Lin28 homolog B (LIN28B) level is significantly elevated in some WTs. Enforced expression of Lin28b during kidney development could induce WT. Genetic variations in the LIN28B gene may be related to WT susceptibility. METHOD: In this study, we aimed to assess the association between LIN28B gene polymorphisms and WT susceptibility in Chinese children...

Several types of vaccine-delivering tumor-associated antigens (TAAs) have been developed in basic and clinical research. Wilms' tumor 1 (WT1), identified as a gene responsible for pediatric renal neoplasm, is one of the most promising TAA for cancer immunotherapy. Peptide and dendritic cell-based WT1 cancer vaccines showed some therapeutic efficacy in clinical and pre-clinical studies but as yet no oral WT1 vaccine can be administrated in a simple and easy way. In the present study, we constructed a novel oral cancer vaccine using a recombinant Bifidobacterium longum displaying WT1 protein...

High-grade serous (HGS) ovarian cancer accounts for 90% of all ovarian cancer-related deaths. However, factors that drive HGS ovarian cancer tumor growth have not been fully elucidated. In particular, comprehensive analysis of the metabolic requirements of ovarian cancer tumor growth has not been performed. By analyzing The Cancer Genome Atlas mRNA expression data for HGS ovarian cancer patient samples, we observed that six enzymes of the folic acid metabolic pathway were overexpressed in HGS ovarian cancer samples compared with normal ovary samples...

Wilms' tumor is one of the most prevalent pediatric malignancies, ranking fourth in childhood cancer worldwide. TP53 is a critical tumor suppressor gene, which encodes a 53 kDa protein, p53. The p53 functions to protect against cancer by regulating cell cycle and apoptosis and maintaining DNA integrity. TP53 gene is highly polymorphic. Several TP53 gene polymorphisms have been considered to be associated with cancer risk. Of them, a nonsynonymous polymorphism, Arg72Pro (rs1042522 C>G), has been most extensively studied for the association with cancer risk; however, few studies have investigated its effect on Wilms' tumor...

Wilms' tumors (WT), which accountfor 6% of all childhood cancers, arise from dysregulated differentiation of nephrogenic progenitor cells from embryonic kidneys. Though there is an improvement in the prognosis of WT, still 10% of patients with WT die due to recurrence. Thus more effective treatment approaches are necessary. We previously characterized the inflammatory microenvironment in human WT and observed the robust expression of COX-2. The aim of this study was to extend our studies to analyze the role of COX-2 pathway components in WT progression using a mouse model of WT...

Tumor-associated antigens have emerged as important immunotherapeutic targets in the fight against cancer. Germline tumor antigens, such as WT1, Wilms' tumor gene 1, are overexpressed in many human malignancies but have low expression in somatic tissues. Recent vaccination approaches to target WT1 have been hampered by poor in vivo immune potency, likely due to the conserved self-antigen nature of WT1. In this study, we use a novel synthetic micro-consensus SynCon DNA vaccine approach with the goal of breaking tolerance and increasing vaccine immune potency...
