Abstract

Down syndrome is the main cause of intellectual disabilities with a large set of comorbidities from developmental origins but also that appeared across life span. Investigation of the genetic overdosage found in Down syndrome, due to the trisomy of human chromosome 21, has pointed to one main driver gene, the Dual-specificity tyrosine-regulated kinase 1A (Dyrk1a). Dyrk1a is a murine homolog of the drosophila minibrain gene. It has been found to be involved in many biological processes during development and in adulthood. Further analysis showed its haploinsufficiency in mental retardation disease 7 and its involvement in Alzheimer’s disease. DYRK1A plays a role in major developmental steps of brain development, controlling the proliferation of neural progenitors, the migration of neurons, their dendritogenesis and the function of the synapse. Several strategies targeting the overdosage of DYRK1A in DS with specific kinase inhibitors have showed promising evidence that DS cognitive conditions can be alleviated. Nevertheless, providing conditions for proper temporal treatment and to tackle the neurodevelopmental and the neurodegenerative aspects of DS across life span is still an open question.

  • DYRK1A is a serine-threonine kinase that utilizes autophosphorylation to enhance activity and stabilize itself, regulates many downstream proteins and transcription factors, and has a crucial role during brain development.

    “DYRK1A is a serine-threonine kinase that utilizes autophosphorylation to enhance activity and stabilize itself, regulates many downstream proteins and transcription factors, and has a crucial role during brain development (Ahn et al., 2006; Arron et al., 2006; Atas-Ozcan et al., 2021; Branchi et al., 2004; Canzonetta et al., 2008; Hammerle et al., 2011; Martinez de Lagran et al., 2004; Park and Ch”
  • DYRK1A may self-regulate by autophosphorylation, which may enhance its own kinase activity while reducing its degradation.

    “DYRK1A may also self-regulate by autophosphorylation which may enhance its own kinase activity while reducing its degradation (Atas-Ozcan et al., 2021).”

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.
