Abstract
Alterations in the bone marrow niche induced by abnormal production of cytokines and other soluble factors have been associated with disease progression in classical BCR-ABL1 negative myeloproliferative neoplasms (MPN). Variations in circulating proteins might reflect local disease processes and plasma proteome profiling could serve to identify possible diagnostic and prognostic biomarkers. We employed a human cytokine array to screen for 105 distinct analytes in pooled plasma samples obtained from untreated young MPN patients (<35 years) with different clinical phenotypes and driver mutations, as well as from healthy individuals. Among molecules that exhibited significantly increased levels in MPN patients versus controls, the top of the list was represented by Dickkopf-related protein 1 (Dkk-1), which also showed the highest potential for discrimination between MPN subtypes. In the next step, a quantitative ELISA was used to measure plasma Dkk-1 levels in 30 young-onset MPN-10 essential thrombocythemia (ET), 10 polycythemia vera (PV), 10 pre-fibrotic primary myelofibrosis (pre-PMF)-and 10 controls. The results suggested that plasma Dkk-1 levels could differentiate ET from pre-PMF, in JAK2 V617F-positive as well as in CALR-positive patients, and also ET from PV in JAK2 V617F-positive patients.

Abstract
To explore how uterine innervations affect expression of Dickkopf-3 (DKK-3) during peri-implantation, we first examined the consequence of uterine neurectomy on embryo implantation events. We observed that amputation of autonomic nerves innervating the uterus led to the failure of on-time implantation in rats. We then analyzed the effect of neurectomy on expression of DKK-3 further using immunohistochemistry and quantitative real-time reverse transcription polymerase chain reaction. We observed that disconnection of autonomic nerve innervation significantly increased DKK-3 expression in the endometrium before and during invasion of the blastocyst. We also observed high levels of DKK-3 immunoreactivity in the vasculature of the uterus during peri-implantation. Thus, we speculate that DKK-3 may relate to implantation. Besides, our findings provide a new line of evidence that DKK-3 may be regulated by the autonomic nervous system.
