  8. Suggest vaspin could be involved in the pathophysiology of cirrhosis, but is not a good indicator of its origin or severity and does not impact the thrombotic activity of platelets. PMID: 28465646
  9. Vaspin may play an important compensatory role in obesity and insulin resistance in elderly people. PMID: 28553648
  10. Studied the effects of vaspin on lipopolysaccharide (LPS)induced acute respiratory distress syndrome (ARDS) in vivo and in vitro, and further explored the molecular basis and potential mechanisms underlying these effects.

  12. Vaspin is modified at all 3 predicted asparagine glycosylation sites near the reactive center loop. Biochemical data demonstrate that glycosylation does not hinder inhibition of the target protease kallikrein 7. Although binding affinity to heparin is slightly decreased, the protease inhibition reaction is still significantly accelerated in the presence of heparin. Glycosylation did not affect thermal stability. PMID: 28668641
  13. Vaspin was associated with a reduced risk of insulin resistance independently of BMI and pubertal stage and the association was influenced by body fat and physical activity in these adolescents. PMID: 27513492

  15. The minor A allele of vaspin rs2236242 polymorphism plays a protective role against obesity and diabetes among women in Upper Egypt. The serum vaspin concentration was lower in minor protective allele carriers. PMID: 28479386

  17. Together, these data show that vaspin binds heparin with high affinity (KD = 21 +/- 2 nm) and that binding takes place at a basic patch on top of beta-sheet A and is different from other heparin-binding serpins. PMID: 27941022
  18. In patients with diabetic nephropathy (DNP), vaspin level does not change within the early stages of DNP; while it is higher in patients with decreased glomerular filtration rate, which may be related with increasing inflammation regardless of the stage of the kidney disease. PMID: 27216464
  19. vaspin could be visibly observed within the detectable concentrations of vaspin up to 5nM in both buffer and serum conditions. The sensitivity of this LFSA developed in this study was ranged from 0.137 to 25nM in buffer and from 0.105 to 25nM in spiked human serum, respectively. T PMID: 27916536
  20. Vaspin acts as a coordinator of the dynamic balance between bone formation and resorption processes; its action is affected by the cytokines of the RANKL/RANK/OPG system. Changes in the relationships between vaspin, bone markers, OPG, and RANKL might contribute to the development of osteoporosis in girls with anorexia nervosa. PMID: 28042653
  21. These findings suggest that vaspin and VAP-1 may play a role in the pathogenesis of psoriasis and can be used as markers of the disease; vaspin levels may reflect the severity of disease. PMID: 25279492
  22. Circulating vaspin levels were lower in nonalcoholic fatty liver disease. PMID: 27493109
  23. Circulating vaspin level is higher in women than in men in obese individuals. Vaspin had mediator effect between visceral fat and fat mass associations with resting metabolic rate in obese participants. PMID: 26058881

  26. High serum vaspin levels are associated with coronary artery disease in patients with type 2 diabetes. PMID: 26972957
  27. Vaspin might be a useful predictive biomarker in patients with AMI, and patients with low vaspin levels might have a high risk of a MACE. In addition, vaspin might have protective effects on the improvement of LVEF after AMI. PMID: 27322007
  28. High levels of serum vaspin is associated with obesity. PMID: 25470626
  29. Low vaspin blood levels in patients with prolactinomas. PMID: 26415032
