Eric R Craig, Angelina I Londoño, Lyse A Norian, Rebecca C Arend
OBJECTIVE: Epithelial ovarian cancer continues to be the deadliest gynecologic malignancy. Patients with both diabetes mellitus and obesity have poorer outcomes, yet research correlating metabolic abnormalities, such as metabolic syndrome, to ovarian cancer risk and outcomes is lacking. This article reviews the literature regarding metabolic derangements and their relationship to epithelial ovarian cancer, with a focus on potential mechanisms behind these associations. METHODS: PubMed and Google Scholar were searched for articles in the English language regarding epithelial ovarian cancer, obesity, diabetes mellitus, and metabolic syndrome, with a focus on studies conducted since 1990...

Immunologists are well aware that cancer regression and increased patient survival with the use of checkpoint inhibitors, such as ipilimumab, an antibody directed against cytotoxic T-lymphocyte-associated antigen 4, CTLA-4 (CD152), is accompanied by concomitant autoimmunity. For over 30 years, a small group of investigators have shown that the rare paraneoplastic syndromes are caused by immunity to shared antigens found on both tumors and on components of the nervous system. In this issue of the European Journal of Immunology, Blachère et al...

INTRODUCTION: Carotid Body Tumors (CBTs) are Paragangliomas (PGLs) located in the head and neck region which usually do not cause overt neuroendocrine symptoms and hypertension. Matrix Metalloproteinases (MMPs) have shown a strong correlation between CBTs and their clinical behavior. Aim of this study is to analyze the relationship between changes in arterial blood pressure and metalloproteinases levels after surgical resection of CBTs. METHODS: We performed a multicenter clinical study on 17 patients with benign and malignant CBTs (5 males; 12 females)...

Tumor lysis syndrome (TLS) is an oncologic emergency triggered by the rapid release of intracellular material from lysing malignant cells. Most common in rapidly growing hematologic malignancies, TLS has been reported in virtually every cancer type. Central to its pathogenesis is the rapid accumulation of uric acid derived from the breakdown of nucleic acids, which leads to kidney failure by various mechanisms. Kidney failure then limits the clearance of potassium, phosphorus, and uric acid leading to hyperkalemia, hyperphosphatemia, and secondary hypocalcemia, which can be fatal...

This article provides a controlled evaluation of the ability of dietary supplementation with a commercially available rice bran extract modified with shitake mushroom extract (MGN-3) to support the immune function by assessing the ability of immunocytes to proliferate and produce cytokines in response to a mitogenic challenge. Twenty-four male Lewis rats were fed a control diet (Maypo sweetened oatmeal) or Maypo containing the recommended daily dose of MGN-3 for 2 weeks. This treatment modestly enhanced mitogen enhanced proliferation of splenocytes and interferon-gamma (IFN-g) production, and significantly increased proliferation of splenocytes to the superantigen toxic shock syndrome toxin-1 (TSST-1) as well as natural killer (NK) cell activity and production of interleukin-2 (IL-2) by stimulated lymphocytes...

In this protocol, we used the T24 human bladder cancer cell line as a source of native antigens to construct fractionated lysate microarrays. Subsequently, these microarrays were used to compare the autoantibody responses of individuals with interstitial cystitis/painful bladder syndrome (IC/PBS) to those of normal female controls. To accomplish this, T24 cells were lysed under nondenaturing conditions to obtain native antigens. These native antigens were then fractionated in 2D using a PF-2D liquid chromatography; the first dimension separated the proteins by their isoelectric points, and the second separated them according to hydrophobicity...

Toxic epidermal necrolysis (TEN) is characterized by an acute detachment and destruction of keratinocytes, affecting large areas of the skin. It is often related to adverse drug reactions. Previous studies have shown that effector CD8+ T cells, which accumulate in the blister fluid, are functionally cytotoxic and act through a classical perforin/granzyme B pathway. It has recently been shown that these cytotoxic T cells also secrete granulysin peptide, which is lethal to keratinocytes. These cytotoxic T cells exert their killer activity against autologous keratinocytes in the presence of the drug...

Acute tumor lysis syndrome (ATLS) is a potentially lethal condition precipitated by the massive release of intracellular components such as nucleic acids, potassium, and phosphorus, following a rapid and widespread lysis of tumor cells. Herein, the authors describe the high incidence and characteristic histopathologic lesions of acute ATLS in p53-deficient mice used in 2 short-term carcinogenicity studies. ATLS was a frequent cause of early death in p53 (+/-) mice in these studies and was consistently associated with the presence of disseminated lymphoma and leukemia...

A large proportion of melanoma patients host a spontaneous T-cell response specifically against ML-IAP-derived peptides. In this study, we describe that some ML-IAP-specific cytotoxic T cells isolated from melanoma patients cross react with an epitope from the auto-antigen SS56. SS56 is a recently described target of autoantibody responses in Sjögren's syndrome (SS) as well as systemic lupus erythematosus (SLE). Here, we describe that SS56 is also an auto-antigen for T cells in SS and SLE. Hence, SS56-specific T cells could readily be detected in circulation and among the infiltrating cells of SLE skin lesions...

Large granular lymphocyte (LGL) leukemia, or LGLL, is characterized by increased numbers of circulating clonal LGL cells in association with neutropenia, anemia, rheumatoid arthritis, and pulmonary artery hypertension (PAH). Emerging evidence suggests that LGLL cells with a CD8(+)CD28(null) phenotype induce these clinical manifestations through direct destruction of normal tissue. Compared with CD8(+)CD28(null) T cells from healthy controls, CD8(+)CD28(null) T cells from LGLL patients have acquired the ability to directly lyse pulmonary artery endothelial cells and human synovial cells...

Human monocyte-derived dendritic cells (DCs), stimulated with granulocyte-macrophage colony-stimulating factor and interleukin-4 for 1 week, major histocompatibility complex killed human tumor cells in 24-hour cytotoxicity assays. These immature DCs were >90% CD11c, major histocompatibility complex class II(+), but <1% were CD83(+) cells. Within 24 hours, these DCs ingested tumor membranes. The DC cells also lysed Jurkat lymphoma cells, but not Jurkat cells genetically knocked out of the Fas-associated death domain (FADD) or caspase-8...

Wild-type Wilms' tumor gene WT1 is expressed at a high level in hematopoietic malignancies including acute leukemia, chronic myelogenous leukemia, and myelodysplastic syndromes, as well as in various kinds of solid cancers. Human cytotoxic T lymphocytes (CTLs), which could specifically lyse WT1-expressing tumor cells with HLA class I restriction, were generated in vitro. It was also demonstrated that mice immunized with the WT1 peptide rejected challenges by WT1-expressing cancer cells and survived with no signs of autoaggression to normal organs that physiologically expressed WT1...

Lentiviral vectors have been tested as vaccination vectors in anti-tumoral and anti-viral models. They efficiently transduce dendritic cells and stimulate strong T-cell responses against the encoded antigen. However, their capacity to stimulate a cytotoxic T-lymphocyte (CTL) response against several antigens has not been evaluated. Broad anti-human immunodeficiency virus 1 (HIV-1) T-cell immune responses are important for the control of HIV replication. We evaluated the potential of polyepitope-encoding lentiviral vectors to induce broad anti-HIV CTL responses...

Wild-type Wilms' tumor gene WT1 is highly expressed not only in hematopoietic malignancies, including leukemia and myelodysplastic syndromes (MDS), but also in various kinds of solid tumors. Human cytotoxic T lymphocytes (CTLs) which could specifically lyse WT1-expressing tumor cells with HLA class I restriction were generated in vitro. We have also demonstrated that mice immunized with the WT1 peptide or WT1 cDNA rejected challenges by WT1-expressing tumor cells and survived with no signs of auto-aggression to normal organs which physiologically expressed WT1 in prophylactic and therapeutic models...

A white blood cell count more than 50 x 10(9)/l, not related to bone marrow involvement, is termed leukemoid reaction. We report on the first case of an undifferentiated sarcoma of the lung associated with an intense paraneoplastic neutrophilic leukemoid reaction related to the production of granulocyte colony-stimulating factor (G-CSF). A radiography and a computed tomography scan of the chest revealed a well-limited voluminous and heterogeneous low-density mass of the left lung. The patient died of multiorgan failure related to uncontrolled progressive tumor growth after admission and two cycles of chemotherapy...

The administration of high-dose continuous intravenous infusion interleukin-2 (IL-2) is able to induce the presence of lymphokine-activated killer (LAK) cells. LAK are able to nonspecifically lyse tumor cells. They are also able to lyse endothelial cells, which accounts for, at least in part, the capillary leak syndrome seen as one of the toxicities with this therapy. A pulmonary manifestation of capillary leak syndrome is the presence of pulmonary edema. We postulated that capillary leak may also be a mechanism by which LAK could conceivably reach pulmonary metastases or could be a reflection of damage of endothelial cells in vasculature supplying metastases and that capillary leak syndrome may actually correlate with the response of pulmonary metastases...

About 15% of all human colorectal, gastric, and endometrial tumors, and the majority of tumors in patients suffering from hereditary nonpolyposis colorectal cancer syndrome, are caused by loss of DNA mismatch repair functions. In the affected cancer cells, this results in insertion or deletion mutations at short, repetitive DNA sequences referred to as microsatellites. Such mutations in coding microsatellites (cMS) cause translational frameshifts that may destroy gene function. These frameshift mutations could also cause the translation of immunogenic neopeptides at the carboxy terminus...

Tumor lysis syndrome (TLS) is an oncologic emergency that occurs when a large number of rapidly dividing cells is lysed. Patients with cancer who have massive tumor burden with cells that are rapidly dividing are at particular risk for this potentially life-threatening complication. This program discussed the risk factors for developing TLS, the laboratory data used to diagnose the syndrome, the signs and symptoms associated with each of the metabolic abnormalities related to the syndrome, and patient management...

The fusion of a murine B cell and a myeloma cell generates a hybridoma that produces monoclonal antibody (mAb). These murine mAb induce the HAMA (human anti-mouse antibodies) response. Murine mAb have been modified by genetic engineering, producing molecules with a higher proportion of human protein. At present, chimeric, humanized and fully human mAb are available. mAb block interactions between target molecules and their ligands or trigger the lyses of mAb-coated tumor cells. Numerous mAb have been developed using the recombinant DNA technology and several are available in the market...
