Abstract

Rationale: Oxidation of cysteine residues in class II histone deacetylases (HDACs), including HDAC4, causes nuclear exit, thereby inducing cardiac hypertrophy. The cellular source of reactive oxygen species responsible for oxidation of HDAC4 remains unknown. Objective: We investigated whether nicotinamide adenine dinucleotide phosphate oxidase 4 (Nox4), a major nicotinamide adenine dinucleotide phosphate oxidase, mediates cysteine oxidation of HDAC4. Methods and Results: Phenylephrine (100 μmol/L), an α1 adrenergic agonist, induced upregulation of Nox4 (1.5-fold; P <0.05) within 5 minutes, accompanied by increases in O 2 − (3.5-fold; P <0.01) from the nuclear membrane and nuclear exit of HDAC4 in cardiomyocytes. Knockdown of Nox4, but not Nox2, attenuated O 2 − production in the nucleus and prevented phenylephrine-induced oxidation and nuclear exit of HDAC4. After continuous infusion of phenylephrine (20 mg/kg per day) for 14 days, wild-type and cardiac-specific Nox4 knockout mice exhibited similar aortic pressures. Left ventricular weight/tibial length (5.7±0.2 versus 6.4±0.2 mg/mm; P <0.05) and cardiomyocytes cross-sectional area (223±13 versus 258±12 μm 2 ; P <0.05) were significantly smaller in cardiac-specific Nox4 knockout than in wild-type mice. Nuclear O 2 − production in the heart was significantly lower in cardiac-specific Nox4 knockout than in wild-type mice (4116±314 versus 7057±1710 relative light unit; P <0.05), and cysteine oxidation of HDAC4 was decreased. HDAC4 oxidation and cardiac hypertrophy were also attenuated in cardiac-specific Nox4 knockout mice 2 weeks after transverse aortic constriction. Conclusions: Nox4 plays an essential role in mediating cysteine oxidation and nuclear exit of HDAC4, thereby mediating cardiac hypertrophy in response to phenylephrine and pressure overload.

  • ROS influence the activity of epigenetic modulators such as HDACs or DNMTs, with consequences evident in the expression of target genes.

    “ROS influence the activity of epigenetic modulators, such as histone deacetylases (HDACs) or DNA methyltransferases (DNMTs) with consequences that are evident in the expression of the target genes38,39.”

    From ROS in cancer therapy: the bright side of the moon (2020) · cites this paper as [38]

    The Discussion links Nox4-derived ROS to HDAC4 oxidation, and the Results section on NFAT target genes reports changes in transcriptional activity and gene expression. The paper supports the HDAC portion of the claim, but the passages do not address DNA methyltransferases (DNMTs). No page numbers are available in our copy. (LLM, conf=0.88)

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.
