Chemotherapy resistance in recurrent gliomas is a large hurdle for successful therapy. Here, the authors show that some recurrent gliomas harbour O-6-methylguanine-DNA methyltransferase (MGMT) genomic rearrangements, and in vitro and in vivo these contribute to temozolomide resistance.

Tropomyosin receptor kinase B (TrkB), encoded by the neurotrophic tyrosine receptor kinase 2 (NTRK2) gene, exhibits intricate splicing patterns and post-translational modifications. Here, the authors perform whole gene and transcript-level analyses and report the TrkB.T1 splice variant enhances PDGF-driven gliomas in vivo and augments PI3K signaling cascades in vitro.

LIF is a pleiotropic cytokine that promotes an immunosuppressive microenvironment and has critical functions in embryonic development. Here, the authors show that LIF regulates CD8+ T cell tumor infiltration in cancer by repressing CXCL19 and promoting the presence of protumoral macrophages and thatLIF inhibition, via neutralizing antibodies, promotes T cell infiltration and synergizes with immune checkpoint inhbitors resulting in tumor regression and immunological memory.

Accurate recapitulation of human disease in animal models requires generation of complex and heterogeneous genetic variation. Here the authors combine RCAS-TVA with CRISPR-Cas9 to generate mouse models of cancer.

The epidermal growth factor receptor (EGFR) signalling is regulated at multiple levels. Here the authors show that the importin RanBP6 acts as a tumor suppressor in Glioblastoma and regulates EGFR signalling through promoting translocation of STAT3 to the nuclei and repressing EGFR transcription.
