Study IDST002772
Study TitleDay-night fluctuations in Cerebrospinal fluid metabolomics
Study TypeCircadian (Naïve animals)
Study SummaryThis study was designed to investigate whether the molecular drivers underlying the diurnal fluctuation of CSF secretion rate could be found in either the choroid plexus tissue itself and/or in the CSF surrounding it. Male Sprague-Dawley rats, kept in light-controlled 12:12 conditions, presented with diurnally modulated CSF metabolite composition. This change was accompanied with differential expression of 2778 genes within the choroid plexus, with several plasma membrane transporters and CLOCK-associated genes diurnally modulated.
