Background: Kallikrein Related Peptidase 3 (KLK3) is secreted by Skene's glands and, is considered ancestral homologues of the male prostate gland and has long been used as a biological marker of prostate cancer. Recent studies have shown that the synthesis of KLK3 can be induced by steroid hormones in different tissues of women and in the menstrual cycle it seems to follow the cyclic variation of estradiol and progesterone. In addition, some environmental pollutants such as bisphenols, phthalate / DBP (DiButyl Phthalate) affect AR (Androgen Receptors) mediated signalling that directly regulates KLK3 secretion. This suggests that environmental factors may play a role in KLK3 secretion.
Methods: 61 healthy women living in a high environmental impact (HEI) area, 58 healthy women living in a low environmental impact (LEI) area were evaluated on possible presence or changes of KLK3 in serum at different phases of the menstrual cycle: blood samples taken in the follicular phase 5th-6th day, ovulatory phase 12th -13th day and luteal phase 19th -20th day of the menstrual cycle. For this aim, an ultra-sensitive kit for KLK3 with a detection limit of 0.001 ng / mL was used.
Results KLK 3 valuesshowed two opposite peaks, women from HEI had a positive peak in the ovulatory phase with mean value of 9.90 ± 3.21 pg / mL while women from LEI had a negative peak in the ovulatory phase with mean values of 3.07 ± 1.49 pg / mL. Progesterone, showed a correlation with KLK3. Women from HEI had higher KLK3 values on average and no significant changes were evident between the three withdrawals in the different phases of the cycle. In contrast, women from LEI had a statistically significant decrease between the follicular and ovulatory phase (p <0.0001) and a statistically significant increase (p <0.0001) between the ovulatory and luteal phase.
Conclusions: The data obtained seem to go beyond the known role of KLK3. The dosage of KLK3 during the various phases of the menstrual cycle, simple to carry out and with low costs, can represent an effective and early biomarker to assess environmental exposure and useful to recognize the risk early and protect female health, not only reproductive.
