Abstract

Background: Glioblastoma (GBM), the most prevalent and aggressive primary brain tumor in adults, has a median survival of merely 14 months. Current therapeutic approaches, including maximal safe resection, radiotherapy, and temozolomide-based chemotherapy, have limited efficacy owing to resistance and the high rate of recurrence.

Methods: We analyzed H&E-stained specimens from 65 patients with glioma using deep learning-based morphological classification and analyzed a mouse model through tissue clearing and 3D imaging. Integrated transcriptomic and single-cell RNA-seq analyses identified PTBP1 as a morphology regulator. We validated the function of PTBP1 through lentiviral knockdown in vitro and in orthotopic models and performed structure-based drug screening against PTBP1 with experimental validation.

Results: We detected a clinically significant association between glioma cell morphology and patient survival times. Mechanistically, PTBP1, an RNA-binding protein abundantly expressed in glioma cells, regulated dual-specificity phosphatase 5 (DUSP5) expression post-transcriptionally and modulate ERK1/2 phosphorylation dynamics, thus reducing glioma stem cell proliferation and enhancing differentiation into neuronal-like cells to suppress tumor growth. Importantly, we developed a nanotherapeutic strategy using A2-PLGA/venetoclax; this strategy repurposes venetoclax, a known clinical drug for leukemia, as a PTBP1-targeting agent that effectively suppresses glioma progression in mouse models.

Conclusion: Our findings establish a novel PTBP1/DUSP5/ERK1/2 axis governing glioma stem cell proliferation and differentiation and identify the A2-PLGA/venetoclax nanoparticle as a mechanistically justified therapeutic candidate for glioblastoma.

Tracing map

Proposed by the machine: these links were found in the paper and verified at the source, without human review. The map will receive a Zenodo DOI once one of the paper's authors has validated it with their ORCID.

What the map holds:

  • 1 repository of the authors' code, each at its verified commit, with its license and how the link was found in the paper;
  • 3 scripts, each with its path and the digest of its content;
  • no match between paragraphs and code yet;
  • neither the text of the paper nor the code itself.

Its JSON (tracing-map.json) is deposited on Zenodo with its DOI once the map is validated.
