General descriptionGlioblastomas are among the most aggressive forms of cancer, associated with low treatment efficacy and poor survival. Recurring glioblastomas are often resistant to first-line chemotherapies (1). There is much interest in studying drug-resistant forms of glioblastomas in the effort to develop effective therapies.

The CT-2A-Luc cell line is derived from a sub-cutaneous, non-metastatic murine glioma (astrocytoma) and is stably transduced with a firefly luciferase-EGFP reporter. CT-2A-Luc cells are marked by high levels of complex gangliosides and low distribution of the anti-angiogenic ganglioside GM3, as well as deficiency in the tumor suppressor PTEN/TSC2, a characteristic present in up to 70% of human high-grade glioma cell lines (2,3). CT-2A tumors are wild-type for p53 and recapitulate several features of human high-grade glioma, including high mitotic index and cell density, nuclear polymorphism, hemorrhage, pseudopalisading necrosis, and microvascular proliferation (4,5).
Source:The parental CT-2A cell line was generated from a malignant astrocytoma formed via implantation of the carcinogen 20-methylcholanthrene in the cerebrum of a C57BL/6J mouse (6). The tumor was maintained through serial intracranial transplants prior to cell line isolation. The CT-2A-Luc luciferase cell line was clonally derived from CT-2A cells transduced with a lentiviral vector harboring a firefly luciferase (Fluc)-IRES-GFP cassette under control of the CMV promoter; cells were subsequently sorted for EGFP expression (7).
