Objective:
Oxytocin (OT) is primarily synthesized in the paraventricular nucleus of the hypothalamus and supraoptic nucleus of the hypothalamus in the central nervous system and exhibits a wide spectrum of central and peripheral activities. OT is involved in lipid metabolism and glucose homeostasis and plays a protective role against liver damage.
Methods:
In this study, we investigated whether CSF OT levels correlates with peripheral glucose, lipid profiles, and/or liver enzymes in Chinese subjects. Sixty-nine subjects (n=36 males; n=33 females) who were recruited from Beijing Jishuitan Hospital participated in the study. Their levels of CSF OT and peripheral parameters were assayed by radioimmunoassay and continuous monitoring assay, respectively.
Results:
There was no significant difference in CSF OT levels between males (53.09±6.88 nmol/mL) and females (52.34±6.87 nmol/mL), and no correlation found between CSF OT levels and peripheral glucose and lipid profiles. Significant negative correlation was observed between CSF OT levels and peripheral ALT and AST concentration in females but not in males.
Conclusion:
Our results support the physiological role of neuropeptides acting on brain sites to regulate liver enzymes, and shed new light on the brain-liver interaction.
