Target Background

Function
(From Uniprot)
Relaxin is an ovarian hormone that acts with estrogen to produce dilatation of the birth canal in many mammals. May be involved in remodeling of connective tissues during pregnancy, promoting growth of pubic ligaments and ripening of the cervix.
Gene References into Functions
  1. Results indicate that serum relaxin may be a clinically useful indicator for diagnostic and prognostic evaluation in epithelial ovarian cancer (EOC) patients. PMID: 29060928
  2. down-regulated in cord blood by prenatal smoking PMID: 28130959
  3. In a population of acute HF patients, admission relaxin serum levels were associated with clinical and echocardiographic markers of pulmonary hypertension, RV dysfunction, and overload, suggesting a role for circulating relaxin as a biomarker in this setting. PMID: 27488261
  4. The digestive tract has been shown to express relaxin receptors; the hormone appears to exert site-specific effects acting at the neural or at the smooth muscle level, mainly by a nitric oxide-mediated mechanism. (Review) PMID: 28606038
  5. a novel fusion transcript comprising the RLN1 and RLN2 genes, was identified. PMID: 26499396
  6. Although serum relaxin level is not a causative factor for benign hypermobility syndrome, the significant increases in patients with hyperkyphosis and pes planus suggest the hypothesis that relaxin has a limited and indefinite role in patients with BJHS. PMID: 25322737
  7. Serum concentrations of relaxin showed a positive association to duration of gestation among women with miscarriage but no association to duration of gestation among women with spontaneous onset of labour. PMID: 26272327
  8. Rln enhanced synergistically BMP-2-induced osteoblast differentiation and bone formation. PMID: 24643989
  9. Relaxin actions in pregnancy include increasing cervical pro-MMP-1 and pro-MMP-3 and decreasing TIMP-1, changes which soften the cervix. PMID: 24640561
  10. For the first time, we bring together the systemic (ovarian) and autocrine/paracrine (intrauterine) sources of RLN, in an attempt to understand how RLN contributes to premature birth in women. PMID: 24640563
  11. Notch signaling can down-regulate TGF-beta1/Smad3-induced fibroblast-myofibroblast transition and that RLX could exert its well known anti-fibrotic action through the up-regulation of this pathway. PMID: 23704950
  12. Recombinant human relaxin (RLX) may provide a novel therapy to manage atrial fibrillation in humans by reversing fibrosis and hypertrophy and by modulating cardiac ionic currents. PMID: 23748429
  13. relaxin may promote the proliferation, invasion and metastasis of osteosarcoma cells by regulating the expression of MMP-9 and facilitating ECM degradation. PMID: 23661525
  14. [review] This study not only clarifies the role of relaxin in sperm, but could also open avenues of research into its use in fertility treatment. PMID: 22180889
  15. heterozygous loss at the RLN1 locus is not a genetic factor mediating high population-wide risk for testicular germ cell tumour, but do not exclude a contribution of this aberration in some cases of cancer PMID: 21696394
  16. Endometrial expression of relaxin and its receptor in endometriosis. PMID: 20655530
  17. In conclusion, we have identified S100A4 as a major mediator of the actions of relaxin in thyroid carcinoma cell motility and in vivo thyroid tumor angiogenesis. PMID: 20332215
  18. Relaxin is a potent stimulator of osteoclastogenesis from hematopoietic precursors and regulates the activity of mature osteoclasts. PMID: 19833242

  28. rhRLX increases cardiac output and reduces arterial load in hypertensive rats without reducing blood pressure. Time of response is dependent on model of hypertension. Rats with angiotensin II hypertension responded more rapidly to rhRLX than SHR. PMID: 16172427

  33. long-term exposure to relaxin confers growth inhibitory and anti-invasive properties in oestrogen-independent tumours in vivo, which may in part be mediated through a down-regulation of S100A4 PMID: 18718015
  34. RXFP1-inactive relaxin activates human glucocorticoid receptor. PMID: 19101597
  35. The hydrogen-bond network and electrostatic interactions between charged groups in INSL5 by NMR-monitored temperature and pH titrations was characterized. PMID: 19178384
