Abstract
Cornelia de Lange Syndrome (CdLS), which is reported to affect about 1 in 10,000 to 30,000 newborns, is a multisystem organ developmental disorder with relatively mild to severe effects. Among others, intellectual disability represents an important feature of this condition.Cornelia de Lange syndrome can result from mutations in at least five genes: NIPBL (nipped-B-like protein), SMC1A (structural maintenance of chromosomes 1A), SMC3 (structural maintenance of chromosomes 3), RAD21 (RAD21 Cohesin Complex Component), and HDAC8 (Histone deacetylase 8). It is believed that mutations in these genes cause CdLS by impairing the function of the cohesin complex (to which all the aforementioned genes contribute to the structure or function), disrupting gene regulation during critical stages of early development.Since intellectual disorder might result from alterations in neural development, in this work, we studied the role of Hdac8 gene in mouse neural stem cells and in vertebrate (D.rerio) brain development by knock-down and chemical inhibition experiments. An underlying features of Hdac8 deficiency is an increased cell death in the developing neural tissues, either in mouse NSCs and in zebrafish embryos.
