Of note, both transthyretin and mir-204 have been implicated in regulating cell survival and may be involved in pathological states, such as Alzheimer’s disease and/or Schizophrenia (Serot et al., 1997; Wan et al., 2006; Turner et al., 2014b; Cammaerts et al., 2015; Li et al., 2016). This evidence concerns the gene TTR and Alzheimer disease.
