Abstract

JHDM1B is an evolutionarily conserved and ubiquitously expressed member of the JHDM (JmjC-domain-containing histone demethylase) family. Because it contains an F-box motif, this protein is also known as FBXL10 (ref. 4). With the use of a genome-wide RNAi screen, the JHDM1B worm orthologue (T26A5.5) was identified as a gene that regulates growth. In the mouse, four independent screens have identified JHDM1B as a putative tumour suppressor by retroviral insertion analysis. Here we identify human JHDM1B as a nucleolar protein and show that JHDM1B preferentially binds the transcribed region of ribosomal DNA to repress the transcription of ribosomal RNA genes. We also show that repression of ribosomal RNA genes by JHDM1B is dependent on its JmjC domain, which is necessary for the specific demethylation of trimethylated lysine 4 on histone H3 in the nucleolus. In agreement with the notion that ribosomal RNA synthesis and cell growth are coupled processes, we show a JmjC-domain-dependent negative effect of JHDM1B on cell size and cell proliferation. Because aberrant ribosome biogenesis and the disruption of epigenetic control mechanisms contribute to cellular transformation, these results, together with the low levels of JHDM1B expression found in aggressive brain tumours, suggest a role for JHDM1B in cancer development.

  • Inactivating mutations and/or reduced expression of JmjC histone demethylases including JARID1C, UTX and JHDM1B/FBXL10 occur in renal cell carcinomas, multiple myeloma, glioblastoma multiforme and several other cancers.

    “Interestingly, inactivating mutations and/or reduced expression of JmjC histone demethylases including JARID1C (Dalgliesh et al, 2010), UTX (van Haaften et al, 2009) and JHDM1B/FBXL10 (Frescas et al, 2007), occur in RCCs, multiple myeloma, glioblastoma multiforme and several other cancers.”

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.
