According to a study being presented at the 23rd European Congress of Endocrinology (e-ECE 2021) on Sunday 23 May, women working night shifts may be at a greater risk of menstrual irregularity and developing endometriosis. The research found a reduction in the expression of PER-2, CRY-1 and CLOCK genes along with an increase in REV-ERBb in ectopic compared to eutopic tissues. Prior to this research, there had been no previously published studies relating to the alterations in core clock-genes and the impact on women with endometriosis.
