Abstract

MECP2 mutations cause a number of neurological disorders of which Rett syndrome (RTT) represents the most thoroughly analysed condition. Many Mecp2 mouse models have been generated through the years; their validity is demonstrated by the presence of a broad spectrum of phenotypes largely mimicking those manifested by RTT patients. These mouse models, between which the C57BL/6 Mecp2tm1.1Bird strain probably represents the most used, enabled to disclose much of the roles of Mecp2. However, small litters with little viability and poor maternal care hamper the maintenance of the colony, thus limiting research on such animals. For this reason, past studies often used Mecp2 mouse models on mixed genetic backgrounds, thus opening questions on whether modifier genes could be responsible for at least part of the described effects. To verify this possibility, and facilitate the maintenance of the Mecp2 colony, we transferred the Mecp2tm1.1Bird allele on the stronger CD1 background. The CD1 strain is easier to maintain and largely recapitulates the phenotypes already described in Mecp2-null mice. We believe that this mouse model will foster the research on RTT.

  • Heterozygous female mice on all genetic backgrounds, as well as female rats, become significantly overweight as they age.

    “Interestingly, heterozygous female mice on all genetic backgrounds, as well as female rats, become significantly overweight as they age [115,117,125], although humans with RTT have a wide range in body mass index [15].”

    From Rett syndrome: a neurological disorder with metabolic components (2018) · cites this paper as [125]

    The Results and Discussion (Fig. 4; page not provided) report that CD1 heterozygous female mice became overweight relative to wild-type controls beginning at three months of age. The paper does not establish this for female mice on all genetic backgrounds or for female rats. (LLM, conf=0.88)

  • Body weight in Mecp2 null mice differs depending on genetic background.

    “Curiously, body weight in Mecp2 null mice differs depending on genetic background; male Mecp2tm1.1Bird/Y mice on a C57BL/6J background are substantially underweight by four weeks of age compared with wild-type littermates.”
  • CD1.Mecp2tm1.1Bird mice have an increase in serum triglycerides with no corresponding change in serum cholesterol.

    “Additionally, CD1.Mecp2tm1.1Bird mice have an increase in serum triglycerides with no corresponding change in serum cholesterol [125].”

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.
