RB1 Loss and the Earliest Cell of Retinoblastoma
2026-09-02
A 2026 Cell Death and Disease study uses RB1-deficient human retinal organoids and longitudinal single-cell analysis to identify ATOH7+/RXRγ+ nascent cone precursors as the earliest cellular origin of human retinoblastoma. The work separates the effects of complete and monoallelic RB1 loss, providing a developmental framework for studying tumor initiation and prioritizing therapeutic targets.

Clathrin-Mediated Entry of Type III GCRV
2026-09-02
Wang et al. used pharmacological inhibition, transmission electron microscopy, and real-time quantitative PCR to show that genotype III grass carp reovirus enters CIK cells through a dynamin-dependent, clathrin-mediated, pH-dependent pathway. The study also shows that Nocodazole did not block infection under the tested conditions, making the compound useful as a negative mechanistic probe rather than evidence that microtubules are universally irrelevant to reovirus biology.

PCMT1 and Ovarian Cancer Metastasis: CRISPR Evidence
2026-09-01
Zhang et al. used a genome-wide CRISPR/Cas9 knockout screen to identify PCMT1 as a driver of anoikis resistance and ovarian cancer metastatic behavior. The study connects extracellular PCMT1 to LAMB3-dependent integrin–FAK–Src signaling, highlighting a potentially targetable interface between tumor cells and the extracellular matrix.
