TMOD-36. PRECISE INVESTIGATION OF CANCER STEM CELLS IN A MOUSE GLIOBLASTOMA MODEL
2018
Cancer stem cells (CSCs) have been shown to play a critical role in glioblastoma (GBM) pathogenesis. However, a precise and thorough understanding of these cells is still lacking. Here we design a novel mouse model to label, purify, and study cancer stem cells in vivo. Firstly we generate and characterize a new transgene to label neural stem/progenitor cells in the subventricular zone (SVZ) with GFP, and drive expression of CreERT2 and human diphtheria toxin receptor in the same cells (CGD: nestin-CreERT2-H2BeGFP-hDTR). Following analysis with both bulk and single cell RNA sequencing of the SVZ tissue demonstrate its faithful expression in the stem/progenitor cell compartment. We then cross…
Erratum: Melanoma Unknown Primary Brain Metastasis Treatment With ECHO-7 Oncolytic Virus Rigvir: A Case Report
2018
Melanoma is considered an aggressive malignancy with a tendency of forming metastasis in the brain. Less than 10% of all melanoma cases present with unknown primary tumor location. This diagnose is yet to be fully understood, because there are only theoretical assumptions about the nature of the disease. Melanoma brain metastases have many severe side effects and, unfortunately, any disease related to the brain has limited therapeutic options due to the blood–brain barrier. The course of the disease after a treatment course is complicated to predict, and it is difficult to obtain long-lasting remission. In this report, we describe a female patient with unknown primary melanoma brain metasta…
Managing Multi-center Flow Cytometry Data for Immune Monitoring.
2014
With the recent results of promising cancer vaccines and immunotherapy 1 – 5 , immune monitoring has become increasingly relevant for measuring treatment-induced effects on T cells, and an essential tool for shedding light on the mechanisms responsible for a successful treatment. Flow cytometry is the canonical multi-parameter assay for the fine characterization of single cells in solution, and is ubiquitously used in pre-clinical tumor immunology and in cancer immunotherapy trials. Current state-of-the-art polychromatic flow cytometry involves multi-step, multi-reagent assays followed by sample acquisition on sophisticated instruments capable of capturing up to 20 parameters per cell at a…
Precision sampling fuels precision oncology: an evolutionary perspective.
2021
Intratumor heterogeneity (ITH) develops in malignant tumors. Precision sampling that captures this tumor variability is essential for the implementation of precision oncology. We highlight the necessity to update current sampling protocols and implement a strategy to ensure ITH detection and characterization. A cost-effective strategy for such sampling has been modeled in clear cell renal cell carcinoma (CCRCC).

Primitive neuroectodermal kidney tumor
2002
To the Editor: Primitive neuroectodermal tumors (PNET) and Ewing sarcoma (ES) belong to a group of neoplasms de®ned by neuroectodermal differentiation and a characteristic cytogenetic translocation, t(11;22) (q24;q12) or gene rearrangements between chromosomes 21 and 22 [1]. They are generally aggressive tumors that present as metastatic disease in nearly 50% of the cases. ES is frequently a bone disease, whereas PNET can occur in bones, soft tissues, or any other site. Renal PNETs are extremely rare, with only a few cases reported [2]. We here record an adult with renal PNET and bone metastases at diagnosis. Because these tumor can also be found in children [3] our experience may therefore…
