    Xu et al. review post-translational modifications (PTMs) in retinoblastoma, linking them to signaling, chromatin regulation, and immune interactions.

  • 2

    The integration of heterogeneous evidence streams in retinoblastoma research complicates the clinical prioritization of PTM-related observations.

  • 3

    Not all compounds affecting PTMs should be classified as PTM-targeting therapies; distinctions between direct and indirect effects are crucial.

  • 4

    Retinoblastoma therapy must consider survival, globe salvage, visual preservation, and ocular safety, emphasizing the need for local drug delivery.

  • 5

    PTM-immunotherapy combinations require retinoblastoma-specific validation due to variability in antigen expression and immune response.
