    text
  • secreted into the blood
    • basic FUNCTION
  • involved in reproduction (in preterm premature rupture of the membrane)
  • physiological changes leading to parturition
  • may promote the invasive potential of early placental extravillous trophoblasts (EVTs) through up-regulating MMP2, MMP9 mRNAs
  • promoting vasodilatory effects, is a therapy target for the treatment of acute heart failure, and has recently been shown to be highly expressed by cancer cells, aiding in their proliferation, invasiveness and metastasis
  • role for the RLN2 ligand-receptor system at the ocular surface and in the lacrimal apparatus as a potential future therapeutic during wound healing at the ocular surface
  • systemic hormone (sRLN) that is produced by the corpus luteum

    of RLN2 and S100A4 might be related to the prediction of metastasis potency and poor prognosis for osteosarcoma patients
    Susceptibility
  • to preterm premature rupture of membranes (PPROM)
  • to spontaneous preterm birth (sPTB)
    • Variant & Polymorphism SNP
  • rs4742076 was associated significantly with PPROM
  • SNP rs3758239 was associated with both PPROM and sPTB
    • Candidate gene
    Marker
  • detection of RLN2 and S100A4 might be useful in evaluating the outcome of patients with osteosarcoma
