Glioblastoma multiforme (GBM) is the most frequent and aggressive primary brain tumor. GBM is formed by a very heterogeneous astrocyte population, neurons, neovascularization and infiltrating myeloid cells (microglia and monocyte derived macrophages). The IQGAP1 scaffold protein interacts with components of the cytoskeleton, cell adhesion molecules, and several signaling molecules to regulate cell morphology and motility, cell cycle and other cellular functions. IQGAP1 overexpression and delocalization has been observed in several tumors, suggesting a role for this protein in cell proliferation, transformation and invasion...

Epstein-Barr virus (EBV) is a gamma herpesvirus associated with diseases ranging from asymptomatic viremia to post-transplant malignancies in kidney transplant recipients. EBV specifically is associated with post-transplantation lymphoproliferative disorder (PTLD), in kidney transplant recipients, with increased risk in EBV seronegative patients with EBV seropositive donors on intensified immunosuppression. The diagnosis of PTLD relies on clinical suspicion plus tissue biopsy with polymerase chain reaction (PCR) testing of blood currently used for risk determination in high-risk recipients...

Recently it has been shown that interferon (IFN)-γ plays an important role in mesothelioma, mediated by the main IFN-γ dependent chemokines, chemokine (C-X-C motif) ligand (CXCL)10/IFN-γ- induced protein 10 (IP-10). IP-10 is up-regulated in malignant mesothelioma (MM), suggesting a relationship with development of these tumors. Nanoparticles containing nickel, that increase the risk for pleural diseases, induced increased levels of IP-10 in rat pleural mesothelial cells. Chemokine (C-X-C motif) receptor (CXCR)3 expression in CD4(+) T cells from pleural plaques and MMs was significantly decreased compared with that from healthy donors suggesting that CXCR3, IFN-γ, and IP-10 may be candidates to detect and monitor disease status...

BACKGROUND: Gastrointestinal carcinomas are genomically complex cancers that are lethal in the metastatic setting. Whole-genome and transcriptome sequencing allow for the simultaneous characterization of multiple oncogenic pathways. METHODS: We report 3 cases of metastatic gastrointestinal carcinoma in patients enrolled in the Personalized Onco-Genomics program at the BC Cancer Agency. Real-time genomic profiling was combined with clinical expertise to diagnose a carcinoma of unknown primary, to explore treatment response to bevacizumab in a colorectal cancer, and to characterize an appendiceal adenocarcinoma...

We previously discovered that Ras association domain family member 6 (RASSF6) was downregulated and predicted poor prognosis in GC patients. However, the mechanisms of the down regulation of RASSF6 in GC remained unclear. Increasing evidence indicates that dysregulation of microRNAs promotes the progression of cancer through the repression of tumour suppressors. Here, we identified miR-181a-5p as a novel regulator of RASSF6 in GC. Functionally, ectopic expression or silencing of miR-181a-5p, respectively, promoted or inhibited GC cell proliferation, colony formation and cell cycle transition, as well as enhanced or prevented the invasion, metastasis of GC cells and epithelial to mesenchymal transition of GC cells in vitro and in vivo...

Breast cancer affects mostly older women but there are no guidelines especially devoted to adjuvant chemotherapy for this population. In this context, this study was carried out in a population-based cohort of French elderly women with breast cancer, to check adherence to the existing national guidelines according to the women's age, taking into account the evolution of the situation over time for women requiring chemotherapy. Between October 2006 and December 2008, all consecutive women included in the French Health registry for a biopsy-proven primary nonmetastatic breast cancer, aged 65-80 years at diagnosis, and living in South Eastern France, were asked to participate in a cohort study...

Harnessing the immune system to eradicate malignant cells is becoming a most powerful new approach to cancer therapy. FDA approval of the immunotherapy-based drugs, sipuleucel-T (Provenge), ipilimumab (Yervoy, anti-CTLA-4), and more recently, the programmed cell death (PD)-1 antibody (pembrolizumab, Keytruda), for the treatment of multiple types of cancer has greatly advanced research and clinical studies in the field of cancer immunotherapy. Furthermore, recent clinical trials, using NY-ESO-1-specific T cell receptor (TCR) or CD19-chimeric antigen receptor (CAR), have shown promising clinical results for patients with metastatic cancer...

RSK2 is a serine/threonine kinase and a member of the p90 ribosomal S6 kinase (p90(RSK); RSKs) family, which regulates cell proliferation and transformation induced by tumor promoters such as epithelial growth factor (EGF), 12-O-tetradecanoylphorbol-13-acetate (TPA), and ultraviolet (UV) radiation. RSKs respond to many growth factors, hormones, neurotransmitters and environmental stresses. In signaling cascades, RSK2 is regulated under the control of extracellular signal-regulated kinase 1 (ERK1) and 2 (ERK2) activities and is positioned upstream of transcription and epigenetic factors involved in cell proliferation, cell transformation and cancer development, as well as some kinases that modulate cell cycle progression...

BACKGROUND: Adverse drug reactions (ADRs) are a global problem and constitute a major clinical problem in terms of human suffering. The high toxicity and narrow therapeutic index of chemotherapeutic agents makes oncology pharmacovigilance essential. The objective of the present study was to assess the pattern of ADRs occurring in cancer patients treated with chemotherapy in a tertiary care teaching hospital in Ethiopia. METHODS: A cross-sectional study over a 2-year period from September 2013 to August 2015 was conducted on cancer patients undergoing chemotherapy at Gondar University Referral Hospital Oncology Center...

Despite of promising improvements in treatment of gastric cancer, the mortality rate of this malignancy remains high. Chronic infection by Helicobacter pylori, interfering with intracellular signalling pathways, is the main risk factor for gastric cancer. Some evidence suggests that microRNAs (miRNA), the small noncoding RNA molecules, can play role as oncogenes or tumour suppressors in the cells. MiR-222 is one of the remarkable miRNAs undergoing upregulation in gastric cancer. However, the association between miR-222 upregulation and H...

Oncolytic adenovirus (Onco(Ad)) is a promising therapeutic agent for treating cancer. However, the therapeutic potential of Onco(Ad) is hindered by hepatic sequestration and the host immune response in vivo. Here, we constructed a PEG/Lipids/calcium phosphate (CaP)-Onco(Ad) (PLC-Onco(Ad)) delivery system for ZD55-IL-24, an oncolytic adenovirus that carries the IL-24 gene. The negatively charged PLC-ZD55-IL-24 were disperse and resisted serum-induced aggregation. Compared to naked ZD55-IL-24, the systemic administration of PLC-ZD55-IL-24 in BALB/c mice resulted in reduced liver sequestration and systemic toxicity and evaded the innate immune response...

BACKGROUND: Disseminated invasive aspergillosis is an exceptional finding in immunocompetent hosts. As in immunocompromised patients, it has high mortality rates. Early diagnostic methods are required in order to properly manage the patient. Bis(methylthio)gliotoxin (bmGT) is a novel biomarker, useful in onco-hematological patients. CASE REPORT: A 70-year-old male, with non-insulin dependent type II diabetes mellitus and a past surgery history of aortic valve replacement with coronary by-pass five years ago, was seen in the emergency department with blurred vision...

Paraproteins are monoclonal Igs or their components (light or heavy chains) that are produced by a clonal population of mature B cells, most commonly plasma cells. These paraproteins or monoclonal proteins are secreted into the blood and subsequently filtered by the glomerulus before entering into urine, where they can cause various types of kidney disease, including both glomerular and tubulointerstitial injuries. Furthermore, a monoclonal protein that causes a specific glomerular or tubulointerstitial lesion in a human can reproducibly cause the same pathology when injected into an animal, supporting unique paraprotein characteristics...

CD19-directed chimeric antigen receptor (CAR) T cells are clinically effective in a limited set of leukemia patients. However, CAR T-cell therapy thus far has been largely restricted to targeting extracellular tumor-associated antigens (TAA). Herein, we report a T-cell receptor-mimic (TCRm) CAR, termed WT1-28z, that is reactive to a peptide portion of the intracellular onco-protein Wilms Tumor 1(WT1), as it is expressed on the surface of the tumor cell in the context of HLA-A*02:01. T cells modified to express WT1-28z specifically targeted and lysed HLA-A*02:01+ WT1+ tumors and enhanced survival of mice engrafted with HLA-A*02:01+, WT1+ leukemia or ovarian tumors...

MicroRNAs (miRs) represent a part of epigenetic control of autoimmunity gaining increasing attention in rheumatoid arthritis (RA). Since cigarette smoking plays important role in RA pathogenesis and reprograms transcriptional profile of miRNAs, we ask if the onco-protein survivin, a novel biomarker of RA, may provide a link between smoking and miRNA. Studying survivin expression in leukocytes of 144 female RA patients we observed that smoking patients had higher survivin transcription and a remarkable spreading of survivin isoforms...
