Corisin
Based on 1 Customer Validation
Corisin is a pro-apoptotic small peptide produced by Staphylococcus species. Corisin binds to serum albumin to target organs such as the lungs and kidneys, induces cellular senescence, apoptosis and epithelial-mesenchymal transition, and accelerates the progression of organ fibrosis including pulmonary fibrosis and diabetic renal fibrosis. Corisin levels are closely associated with coronavirus disease 2019 (COVID-19), diabetic chronic kidney disease (CKD), non-diabetic CKD, and idiopathic pulmonary fibrosis (IPF).

Biological Activity
Corisin (48 h) significantly increases phosphatidylserine externalization in human umbilical vein endothelial cells, and this effect is blocked by anti-Corisin monoclonal antibodies[1].
Corisin (5 μM; 24 h) significantly enhances tissue factor activity in A549 alveolar epithelial cells, THP-1 monocytes and human umbilical vein endothelial cells, and this effect is reversed by anti-Corisin monoclonal antibody or anti-TF antibody[1].
Corisin (5 μM; 24 h) significantly reduces thrombomodulin activity in A549 alveolar epithelial cells, THP-1 monocytes and human umbilical vein endothelial cells, and this effect is reversed by anti-Corisin monoclonal antibodies[1].
Corisin (20-40 μg/mL; 24-48 h) promotes apoptosis, disrupts cell cycle progression and reduces proliferative activity in normal human renal proximal tubular epithelial cells, human Caki-2 renal tubular epithelial cells and normal human podocytes, while anti-Corisin monoclonal antibodies inhibit these effects[2].
Corisin (20-40 μg/mL; 48 h) induces cellular senescence in human Caki-2 renal tubular epithelial cells, normal human primary renal tubular epithelial cells, and normal human primary podocytes, which is characterized by increased senescence-associated β-galactosidase activity, altered expression of senescence marker genes, and abnormal nuclear morphology. This effect is inhibited by anti-Corisin monoclonal antibodies[2].
Corisin (20-40 μg/mL; 48 h) induces epithelial-mesenchymal transition in human normal primary podocytes and human normal primary renal proximal tubular epithelial cells, which is characterized by changes in cell morphology and upregulated expression of mesenchymal marker genes, while anti-corisin monoclonal antibodies inhibit these effects[2].
Stimulation of primary human renal proximal tubular epithelial cells with Corisin (20 μg/mL; 24 h) activates pathways associated with DNA damage response, cellular senescence, senescence-associated secretory phenotype, and myofibroblast-like differentiation[2].
Corisin (0.5-50 μM; 16-48 h) induces dose-dependent apoptosis in A549 alveolar epithelial cells[3].

Increased Annexin V-positive cells to 13.7% at 0.5 μM, 21.1% at 5 μM, and 22.7% at 50 μM, all significantly higher than the control 6.2%.
Confirmed apoptotic morphology via transmission electron microscopy at 5 μM.
Corisin (administered intratracheally; once daily for 2 consecutive days) induces acute exacerbation of pulmonary fibrosis in TGFβ1 TG mice, which is characterized by significant increases in pulmonary inflammation, collagen deposition, levels of profibrotic mediators, and epithelial cell apoptosis[3].

Animal Model:TGFβ1 transgenic (female, 9 weeks old)[2]
-
Dosage:5 mg/kg
-
Administration:i.p.; thrice weekly; 2 weeks
-
Result:Elevated urinary levels of corisin, albumin, and albumin-to-creatinine ratio significantly compared to scrambled peptide-treated mice.
Elevated plasma blood urea nitrogen (BUN) and urinary liver-type fatty acid-binding protein (L-FABP) levels significantly compared to scrambled peptide-treated mice.
Elevated plasma levels of lipopolysaccharide-induced CXC chemokine (LIX/CXCL5), macrophage inflammatory protein-2 (MIP-2), interleukin-1β (IL-1β), platelet-derived growth factor (PDGF), tissue factor (TF), and plasminogen activator inhibitor-1 (PAI-1) significantly compared to scrambled peptide-treated mice.
Increased mean circulating corisin levels to 2.2-fold higher than those in diabetic CKD patients and 1.6-fold higher than those in diabetic TGFβ1 transgenic mice.
Increased renal fibrotic changes significantly compared to scrambled peptide-treated mice.
