In 1996 a cDNA called KISS1 (KI in reference to the place of discovery-Hershey Pennsylvania, home of the famous Hershey Chocolate Kisses- and SS as suppressor sequence) was identified in non-metastatic melanoma cell lines. Its 54 amino-acid product, Kisspeptin-54 (Kp-54), was originally called metastin for its ability to inhibit cancer metastasis through the activation of a G coupled receptor, previously known as GPR54 and currently renamed the Kisspeptin receptor (KISS1R). Shorter active peptides all capable of binding to KISS1R have been identified and the physiological activities of these Kisspeptins are now known to extend not only to the suppression of metastasis. Kisspeptins currently represent evolutionarily conserved biological modulators, with a recognized role in the central control of sex maturation, reproduction and fertility. Consequently, the focus on the central role of the Kisspeptins has led to neglecting their possible activities in peripheral tissues. Increasing data reveals that Kisspeptins and KISS1R have a wider expression and possibly a broader spectrum of action in several peripheral tissues such as the gonads, adipose tissue, and liver with direct consequences on gamete quality and fertility rate, pregnancy, energy homeostasis and body weight control. In this respect, the Kisspeptin system may represent a promising prognostic/diagnostic biomarker and therapeutic target for cancer and other human diseases such as infertility and metabolic disorders. This Research Topic provides a comprehensive picture of the recognized and the emerging role of the Kisspeptin system. Such a volume is very timely and useful to the wide community of researchers in the field and for the scientific community at large.
