Study Title | Investigation of 3,5,3’-L-triiodothyronine (T3) and 3,5,3’5’-L-tetraiodothyronine (T4) by targeted LC-MS analysis from mouse adult or embryonic CSF and from adult serum. |
Study Summary | To maximize discovery from samples with limited amounts, we optimized a method to detect the thyroid hormones ( 3,5,3’-L-triiodothyronine (T3) and 3,5,3’5’-L-tetraiodothyronine (T4)) as well as polar metabolites from central carbon metabolism from mouse adult or embryonic CSF and from adult mouse serum. Samples were ran on reverse phase and HILIC chromatography respectively. For T3 and T4 analysis we utilized targeted analysis using information from previously ran synthetic standards. We interrogated relative changes between fresh and frozen adult (male or female) CSF compared to fresh and frozen embryonic CSF. This data presents the levels of T3 and T4 as interrogated by reverse phase chromatography |

Project Title: | Optimized Mass Spectrometry Detection of Thyroid Hormones and Polar Metabolites in Rodent Cerebrospinal Fluid |
Project Summary: | Thyroid hormones (TH) are required for brain development and function. Cerebrospinal fluid (CSF), which bathes the brain and spinal cord, contains TH as free hormone, or as bound to transthyretin (TTR). Tight TH level regulation in the central nervous system is essential for de-velopmental gene expression that governs neurogenesis, myelination, and synaptogenesis. This integrated function of TH highlights the importance of developing precise and reliable methods for assessing TH levels in CSF. We report an optimized liquid chromatography-mass spectrome-try (LC-MS) based method to measure TH in rodent CSF and serum, applicable to both fresh and frozen samples. Using this new method, we find distinct differences in CSF TH in pregnant dams vs. non-pregnant adults and in embryonic vs. adult CSF. Further, targeted LC-MS metabolic pro-filing uncovers distinct central carbon metabolism in the CSF of these populations. TH detection and metabolite profiling of related metabolic pathways open new avenues of rigorous research into CSF TH and will inform future studies on metabolic alterations in CSF during normal de-velopment. |
