Abstract

PURPOSE: RDH11 and RDH12 are closely related retinol dehydrogenases expressed in the retina. RDH12 has been linked to the early-onset retinal dystrophy Leber congenital amaurosis, whereas RDH11 has not been associated with human disease. To understand their physiological roles, the authors investigated their expression during development and their regulation by light-induced oxidative stress in mouse retina. METHODS: Quantitative RT-PCR and immunoblot analysis were used for quantification of RDH11 and RDH12 during development and oxidative stress. Expression during development was measured between embryonic day (E) 12 and postnatal day (P) 210 (7 months) in C57BL/6 mouse eyes. Expression during light-induced oxidative stress was measured between 2 and 24 hours of exposure to light in BALB/c mouse retina. RESULTS: The RDH11 level was low and remarkably constant during development and oxidative stress. RDH12 expression started at P7 and increased until P30 to approximately sevenfold higher than RDH11. Oxidative stress induced by exposure to constant bright light led to a rapid and significant decrease of RDH12 protein. CONCLUSIONS: The low and constant expression of RDH11 suggested a housekeeping function for this enzyme. The onset of RDH12 expression during the maturation of photoreceptor cells suggested a function related to the visual process. The light-induced rapid decrease of RDH12 protein, preceding the decrease of the mRNA, suggested a specific degradation of the protein rather than a regulation of gene expression.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The close proximity (<350 kb) of two adjacent genes that regulate homologous recombination (ZFYVE26 and RAD51B), two visual genes (RDH11 and RDH12), and PLEKHH1 represents a case of adaptive linkage.

    “We hypothesize that the close proximity (<350 kb) of two adjacent genes that regulate homologous recombination (ZFYVE26 and RAD51B, which directly interact with BRCA2), two visual genes (RDH11 and RDH12) related to retinol metabolism and dark adaptation (62), and one of our candidate domestication genes, PLEKHH1 (S2.4 in Dataset S2), represents such a case of adaptive linkage.”

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.
