The interaction between menstrual cycle, Tumour Necrosis Factor alpha receptors and sex hormones in healthy non-obese women – results from an observational study
Journal Title: Annals of Agricultural and Environmental Medicine - Year 2014, Vol 21, Issue 3
Abstract
There is growing evidence that TNF-alpha and its two receptors play an important role in hormonal regulation, metabolism, inflammation and cancer. The biological effects of TNF-alpha are mediated by two receptors, p55 and p75. The aim of this study was to analyze serum concentrations of p55 and p75 and hormonal status in healthy women during the normal menstrual cycle. Eight women aged 20–22 with regular menstrual cycles were scheduled for examination on 3[sup]rd[/sup] , 8[sup]th[/sup] , 14[sup]th[/sup] and 25[sup]th [/sup] day of their menstrual cycle. We only observed a positive correlation of p75 subunit with prolactin level (correlation coefficient 0.417; p=0.0116) and negative correlation with insulin level (correlation coefficient -0.35; p=0.032) and HOMA[sub]IR[/sub] insulin resistance index correlation coefficient 0.39; p=0.0185). Furthermore, a negative correlation of p55/p75 ratio with prolactin (correlation coefficient -0.42; p=0.0101) and a positive correlations of p55/p75 ratio with insulin level (correlation coefficient 0.43; p=0.008) and HOMA[sub]IR[/sub] insulin resistance factor correlation coefficient 0.45; p=0.0065) were found.
