Abstract

The deubiquitinating enzyme BAP1 is a tumor suppressor, among others involved in cholangiocarcinoma. BAP1 has many proposed molecular targets, while its Drosophila homolog is known to deubiquitinate histone H2AK119. We introduce BAP1 loss-of-function by CRISPR/Cas9 in normal human cholangiocyte organoids. We find that BAP1 controls the expression of junctional and cytoskeleton components by regulating chromatin accessibility. Consequently, we observe loss of multiple epithelial characteristics while motility increases. Importantly, restoring the catalytic activity of BAP1 in the nucleus rescues these cellular and molecular changes. We engineer human liver organoids to combine four common cholangiocarcinoma mutations (TP53, PTEN, SMAD4, and NF1). In this genetic background, BAP1 loss results in acquisition of malignant features upon xenotransplantation. Thus, control of epithelial identity through the regulation of chromatin accessibility appears to be a key aspect of BAP1's tumor suppressor function. Organoid technology combined with CRISPR/Cas9 provides an experimental platform for mechanistic studies of cancer gene function in a human context.

  • Multiplexed gene-knockout by conventional CRISPR/Cas9-mediated NHEJ is very efficient and can be readily applied in organoids.

    “Multiplexed gene-knockout by conventional CRISPR/Cas9-mediated NHEJ is very efficient and can be readily applied in organoids13,14,62.”

    From One-step generation of tumor models by base editor multiplexing in adult stem cell-derived organoids (2023) · cites this paper as [62]

    In “Generation of Cas9-gRNA plasmid, organoid electroporation and generation of KO lines” (page not provided), the paper describes co-injecting four or five Cas9-guide plasmids and says that, after TP53-mutant selection, the vast majority of organoids also carried mutations in the other targeted genes. This supports multiplex knockout in human liver organoids, but does not establish that NHEJ-mediated knockout itself is very efficient or readily applicable across organoids generally; the reported high efficiency is co-transfection in a selected population.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
