The invention provides generally a method of monitoring, diagnosing, prognosing and treating glioma. Specifically, the invention provides for three (3) prognostic subclasses of glioma, which are differentially associated with activation of the akt and notch signaling pathways. Tumor displaying neural or proneural PN lineage markers (including notch pathway elements) show longer median patient survival, while the two remaining tumor markers Prolif and Mes are associated with shortened survival. Tumors classified in this manner may also be treated with the appropriate PN- Prolif- or Mes-therapeutic corresponding to the subclassification in combination with anti-mitotic agents, anti-angiogenic agents, Akt antagonists, and neural differentiation agents. Alternatively, the invention also provides for method of prognosing and diagnosing glioma with a two-gene model based on the expression levels of PTEN and DLL3.

The invention discloses a preparation method of a zebrafish notch1b gene mutant. The preparation method includes: determining positions of knock-out target spots of the notch1b gene; utilizing pUC19-gRNA scaffold plasmid as a template, and performing PCR (polymerase chain reaction) amplification with primers T7-notch1b-sfd and tracr rev; subjecting a PCR product to purification and in-vitro transcription to obtain gRNA (guide ribose nucleic acid); introducing the gRNA and Cas9mRNA into a cell-stage embryo of zebrafish, and culturing to obtain the notch1b gene mutant stable in inheritance.

Methods and compositions are provided for inhibiting the responsiveness of CD4⁺ T cells that have been sensitized to antigen, i.e. CD4⁺ memory, or effector T cells. It is shown herein that such effector T cells will fail to proliferate in response to antigen when inhibited by two compounds, which act on two distinct signaling pathways, the mTOR pathway and the MAPK (MEK) pathway. A synergistic combination of inhibitors is required to achieve effector T cell inactivation because a single inhibitor can provide for inactivation of naïve CD4⁺ T cells, but will not by itself inactivate the sensitized effector T cells.
