Human follicular fluid neurotransmitters LC-MSMS


ABSTRACT: Pretreated human follicular fluid was prepared for targeted metabolomics experiments. For this purpose, 12-point standard calibration curves in the respective range with reference material were measured, and the limit of detection (LOD) and limit of quantification (LOQ) for each neurotransmitter under investigation were calculated. LC-MS/MS was conducted by an ultra-performance liquid chromatography method using a Waters ACQUITY UPLC BEH C18 column (2.1 mm×100 mm, 1.7 µm, Waters, USA). The Waters acquisition UPLC was coupled to an API 4000 triple quadrupole mass spectrometer (AB SCIEX, USA). The mobile phase A buffer was 10% methanol in water (containing 0.1% formic acid), and the mobile phase B buffer was 50% methanol in water (containing 0.1% formic acid). The LC gradient elution was at a flow rate of 0.3 mL/min at 0-8.0 min and 0.4 ml/min at 8.0-17.5 min, then 10%-30% B at 0-6.5 min; 30%-100% B at 6.5-7 min; 100% B at 7-14min; and 100%-10% B at 14-17.5min. The injection volume was 5 µl and the column temperature was set to 40 °C. Twenty-three metabolites (Ach: Acetylcholine chloride; Gln: Glutamine; Glu: Glutamate; His: L-Histidine; NE: norepinephrine; Tyr:Tyrosine; Trp:Tryptophan; Kyn: Kynurenine; GABA: 4-Aminobutyric acid;HisA:Histamine; PA:Picolinic acid;TyrA:Tyramine;DA:Hydroxytyramine hydrochloride; TrpA:Tryptamine;5-HT:Serotonin hydrochloride;E:Adrenaline hydrochloride;KynA:Kynurenic acid;5-HIAA:5-Hydroxyindole-3-acetic acid;DOPA:Levodopa;XA:Xanthurenic acid;VWA:Vanillymandelic Acid; 5-HTTP:5-Hydroxytryptophan;MT:Melatonine)were simultaneously reported in LC-MS/MS multiple reaction monitoring (MRM) mode. Data analysis was performed with Analyst 1.6 software.

Glutamine and norepinephrine in follicular fluid synergistically enhance the antioxidant capacity of human granulosa cells and the outcome of IVF-ET.

An increasing number of studies demonstrate that changes in neurotransmitters metabolic levels in follicular fluid are directly related to oocyte maturation, fertilization, the quality of embryo and pregnancy rates. However, the relationship between the intra-follicular neurotransmitters and the function of granulosa cells (GCs), and the outcome of in vitro fertilization-embryo transfer (IVF-ET) is not clear. Human follicular fluid and cumulus GCs were harvested from large follicles obtained fro  ...[more]
