Siblings diagnosed with same cancer within weeks of each other

Doctors in California are trying to solve a family's stunning medical mystery. Two young siblings, four and six years old, were diagnosed with the same kind of brain tumor within two weeks of each other. Now, their parents are speaking out in hopes of raising awareness and encouraging new research. Jamie Yuccas reports.

Investigators at the NCI Laboratory of Immune Cell Biology  discovered an Anti-TNF Induced Apoptosis (ATIA) protein, which protects cells against apoptosis.  ATIA is highly expressed in glioblastoma and astrocytomas and its inhibition results in increased cell sensitivity to TNF-related apoptosis-inducing ligand induced cell death.  Hence, ATIA assays ma y enable clinicians to effectively stratify patients for appropriate treatment.  ATIA exists in a soluble form that can be detected in culture medium of ATIA expressing cells indicating it could be used to develop a non-invasive, blood based diagnostic ...

Authors: Sun S, Du G, Xue J, Ma J, Ge M, Wang H, Tian J Abstract Indoleamine 2,3-dioxygenase (IDO), which is highly expressed in human glioblastoma and involved in tumor immune escape and resistance to chemotherapy, is clinically correlated with tumor progression and poor clinical outcomes, and is a promising therapeutic target for glioblastoma. IDO inhibitors are marginally efficacious as single-agents; therefore, combination with other therapies holds promise for cancer therapy. The aim of this study was to investigate the anti-tumor effects and mechanisms of the IDO inhibitor PCC0208009 in combination with temoz...

In this study, human glioma U251 cells and rat glioma C6 cells were treated with different concentrations of β-asarone. Cultured them for 24 h, 48 h, 72 h and evaluated the IC50 with the results of Counting Kit-8 assay. Then, cell apoptosis and cell DNA cycles were evaluated with flow cytometry. Apoptosis related mRNA and protein were analyzed In addition, cell migration and invasion were also detected with wound healing and transwell assays, respectively. What is more, glioma specific proteins: GFAP, NRP-1 and NSE an enzyme-linked immunosorbent assay. The corresponding CCK-8 results showed that β-asarone a...

(Johns Hopkins Medicine) In a 'proof of concept' study, scientists at Johns Hopkins Medicine say they have successfully delivered nano-size packets of genetic code called microRNAs to treat human brain tumors implanted in mice. The contents of the super-small containers were designed to target cancer stem cells, a kind of cellular 'seed' that produces countless progeny and is a relentless barrier to ridding the brain of malignant cells.

Here, we show that a ...

Authors: Parker Kerrigan BC, Hossain A, Yamashita S, Lang FF Abstract Stem cells (SC) are the seeds of tissue repair and regeneration that have been extensively investigated as tumor-tropic vectors for gene delivery to solid cancers. SC have an inherent glioma tropism that supports their use as reliable vehicles to deliver therapeutic gene products to brain neoplasms. Several types of adult SC (ASC) have been used to carry antiglioma agents, and neural SC (NSC) and mesenchymal SC (MSC) are the most studied. The therapeutic cargoes that have been tested include secreted proteins, converting enzyme/prodrug suicide co...

Authors: Kim JW, Chang AL, Kane JR, Young JS, Qiao J, Lesniak MS Abstract Despite many recent advances in the management of gliomas, such as aggressive surgical resection, chemoradiotherapy, antiangiogenic therapy, and molecular targeted therapy, the survival of patients with high-grade neoplasms remains dismal. Gene therapy and oncolytic virotherapy have emerged as highly promising strategies for treatment of malignant brain tumors due to recent progress in understanding of the underlying cancer biology as well as improved techniques for genetic modification of potential therapeutics.

Authors: Wipfler K, Cornish AS, Guda C Abstract Glioblastoma (GBM) is the most common and the deadliest type of primary brain tumor, with a median survival time of only 15 months despite aggressive treatment. Although most patients have an extremely poor prognosis, a relatively small number of patients survive far beyond the median survival time. Investigation of these exceptional responders has sparked a great deal of interest and is becoming an important focus in the field of cancer research. To investigate the molecular differences between typical and exceptional responders in GBM, comparative analyses of somati...

Brain tumors are the most common malignancy of childhood. Approximately 50% of pediatric CNS tumors are astrocytomas, most low grade. Low grade glioma (LGG) are WHO grade I or II tumors. Pilocytic astrocytoma (PA) is the most common; accounts for 33% of all gliomas in children 0 –14 years and ∼18% of all childhood brain tumors. Prognosis with this slow-growing tumor is excellent; 10 year overall survival of ∼95%. However, event free survival averages ∼50%. Patient age and extent of tumor resection are key prognostic factors; tumor location and size impact resection and outcome.
